specialists who know how to explain their subjects clearly and interestingly1 without unnecessary technicalities and with keen appreciation of the popular and constantly increasing desire for scientific knowledge4 ,the supreme importance of science in the wonderful age in which our lot has been cast was demonstrated with overwhelming force of conviction by the events of the ,world ,war4 ,if1 as certain persons assert1 science may be accused of having rendered war more destructive and terrible1 yet1 on the other hand1 no one can deny that it was science that saved the world from sliding backward into an age of despotism4 ,the true importance of science for everybody arises from its rapidly increasing service in the development of human industry in all its forms1 for industry is the mother of democracy4 ,said ,gabriel ,lippman1 the ,french physicist1 inventor of color photography1 who died in the summer of #aiba3 ,for thousands of years science progressed by groping and feeling its way1 and coincidentally industry got slowly on by guesswork2 but within the last century science has developed more than during all preceding time1 while industry has sprung upon its feet and begun to march with the strides of a giant4 ,notwithstanding its immense importance and the vast extent and complication of its application in modern times1 science is not really difficult for any person of ordinary school education and of good natural intelligence to comprehend1 provided it is presented in a clear1 plain1 common sense manner1 in popular language with illustrations drawn from everyday life and experience4 ,the much talked-of methods of science are1 after all1 nothing more than the methods of common sense1 applied with systematic care by minds disciplined to a high degree of efficiency4 ,and1 in fact1 the only practical difference between the mind of a trained scientist and that of any other intelligent person is that the scientist has acquired a way or habit of looking at and thinking about things and events1 which enables him to get at their inmost nature and meaning more swiftly and accurately than he could do if he went to work in a haphazard manner as1 in truth1 his forerunners of the earlier centuries were obliged to do4 ,the pioneer must always work by rule of thumb1 but when he has exploited his field he knows better ways4 ,each branch of science has its own particular methods1 but it is not necessary for the average reader to study these special methods in order to become able to grasp the facts and principles that have been developed by them4 ,the results are all thrown into a common store--or should be if science is to attain its utmost usefulness to humanity--and from the common store the great public1 the people at large1 should be enabled freely to draw4 ,the object of this series of books is to form such a store of science for the people4 ,it may encourage those who look with some degree of timidity upon the task of trying to understand the great discoveries and achievements of modern science to know that even the ablest scientists1 leaders in their own particular branches1 do not pretend1 or attempt1 to grasp the special methods or the technicalities of any division of science except that one in which their own work is done4 ,they stand1 with regard to other branches1 practically on the same footing with the unscientific reader1 having over him only such possible advantages as their special training in clear thinking and in the intense application of the mental powers may give them4 ,besides1 science is really the most interesting thing in the world--outside of men and women--and they would be less interesting1 even to themselves1 if science had not transformed their lives as well as their surroundings4 ,if one of ,voltaire's favorite messengers from some other1 wiser world had visited our earth a few hundred years ago1 or even only one hundred1 and should now repeat his call1 he would be amazed1 and no doubt delighted1 by the changes in every feature of life and society which he would find that science had brought about1 as if by magic1 during the interval between his visits4 ,he would be likely to exclaim3 ,some great teacher and trainer from a more enlightened part of the universe must have been here since ,i saw this world before4 ,what a marvelous new spirit he has imparted to these creatures4 ,through him they have become more masterful and more like sons of ,god4 ,see if you can find a single detail of your daily life that is not affected by science1 or upon which science does not throw new light4 ,it is fascinating to trace out the scientific relations of the simplest things that surround us1 or the most ordinary occurrences and incidents4 ,start with your first awakening in the morning1 and you will perceive that there is not a thing that you see1 or that in any way attracts your attention1 that is not touched and illuminated by science1 and often in the most unexpected and delightful ways4 ,it is by considering these things that one may best perceive how to use the volumes of this little library4 ,as you open your eyes in the morning you see a bright glow through the window curtain1 then you know that the sun has risen4 ,but stop a moment4 ,what does that mean--the sun has risen8 ,the sun has not risen at all4 ,but1 one of the greatest facts of the science of astronomy is illustrated before your eyes--a fact that it took mankind thousands of years to find out4 ,you are standing in the astronomer's shoes now1 if you choose to wear them4 ,this is a part of his field of science4 ,it took him a long time to convince the world that the rising of the sun in the east next morning after its setting in the west really means that the globular earth has turned half way over during the night4 ,if this seems simple to you now1 it seemed very hard to comprehend to our remote ancestors1 who1 though reasoning men like ourselves1 had not learned as much about the relativity of motion as we now know1 though even we may be puzzled by some of the consequences that ,einstein has drawn from it4 ,and a hundred other things that astronomy has discovered about the sun and the other suns1 called stars1 and the other worlds1 called planets1 immediately rush to your mind1 and you turn to the volume on astronomy to read about them4 ,but this is only a beginning of the string of everyday incidents that are rendered curiously interesting as soon as their scientific relations and meanings become evident to you4 ,science is right at your elbow to raise questions and to answer them the moment you step out of bed1 and your mind begins to work4 ,as you throw open the window to see what kind of a day it is going to be1 whether fair1 or cloudy1 or rainy1 cool or warm1 you draw your conclusions from the appearance of sky and air1 but in doing that you are entering another field covered by another branch of science and included in our little library--meteorology1 or the realm of the air--and you may be sure that the correctness of the conclusions that you draw from the aspect of the clouds and the feeling of the air will be greatly increased1 not only in certainty1 but also in interest1 if you read what the students of this subject have learned about the laws and the mysteries of the rains1 clouds1 cyclones1 barometric pressures1 great winds and genial breezes1 great storms and little storms2 in short1 the whole wonderful science of the atmosphere1 that invisible1 yet powerful kingdom of the air1 which we are just beginning to annex to our world of activities without regard to what its natural occupants1 the birds1 think of such an invasion4 ,now you leave the window to begin making your morning ablutions4 ,you turn on a faucet and take a drink1 or plunge hands and face into the refreshing liquid1 so cool1 lively1 and invigorating4 ,but a bird or any four-footed animal may find just as keen physical enjoyment in the touch and taste of the water as you do4 ,you1 however1 because you are a thinking being1 possess a source of enjoyment from the touch and appearance of the water that is not open to those humbler creatures1 and that source of enjoyment springs from the principles and facts of another branch of science which the mere sight of the running water may call to mind if you have caught the spirit of these books--the science of chemistry1 whose early history is filled with that irresistible kind of romance that pertains to the search for ,eldorado1 or the strivings of the human spirit after the powers of magic2 for the realm of chemistry was once a kind of semi-scientific dreamland1 wherein the alchemists delved at the same time for the philosopher's stone which was to turn base metal into gold1 and for the wand of the magician which would give to its possessor the boundless gratifications of a ,faust4 ,water is no mystery to the lower animals1 but it is a great mystery even yet to the highest ones--ourselves--because we have been enabled to analyze it4 ,you cannot look at it pouring from the faucet1 and sparkling into bubbles1 without recalling the fact that it is composed of two invisible1 silent gases1 and that chemistry tells us not only how to make the water disappear by taking those gases apart1 but also how to form new water by making the two gases combine4 ,the mystery is--why should this be so8 ,it is a captivating question1 and the business of the book on chemistry is to give you all possible light on the solution of that question1 and others of a like nature4 ,you will find1 too1 that the very latest chemistry has1 strangely enough1 discovered a sort of justification for the extravagant expectations of the ancient alchemists1 by finding a way in which one substance may actually change1 or be changed1 into another1 different substance--one element taking the form of another element--and also by getting clues to the existence of marvelous locked-up energies in matter1 the release of which would give man control over powers that could properly be called magical4 ,after finishing your toilet1 with all the suggestions and remembrances of chemical science that it has produced1 you start to quicken the circulation of your blood by catching up a pair of dumb-bells1 or ,indian clubs1 or by pulling elastic cords1 or banging a leather ball with your fists1 as if you meant to go in for the championship of the world4 ,now1 what taught you the value of such exercises8 ,you are still on the ground of science1 and you are practically demonstrating the principles of another of its branches--the science of health1 or hygiene1 which is a part of the subject of medicine1 taken in its broadest signification1 for1 as the volume on that subject will assure you1 the greatest service that this science can render to mankind is in teaching us the laws of our physical existence1 and indicating1 directly or indirectly1 how all the functions of the body may be kept in the best working order by proper attention and exercise4 ,you will find such things pointed out in the several sciences that deal with the body1 such as physiology and medicine4 ,while you are making the leather ball strike the ceiling with resounding whacks1 your dog1 excited by the inspiring noise1 bursts into the room1 and interrupts your exercise with his enthusiastic morning greetings1 expressed as energetically by his wagging tail as by his joyous barks and licks1 all anticipatory of a lively morning run4 ,he brings immediately into your mind the thought of still another division of science--zology--to which you will devote many pleasant half-hours of reading1 for it is full of most entertaining matter1 as well as of matter calculated to awaken profound and useful thought concerning the relations of the many different members of the animal world to one another1 and especially to their head and chief1 man1 to whom the supervision of the whole was1 according to the ,bible story1 originally committed4 ,familiar as your dog may be to you1 there are a hundred particulars of his family relationships1 his descent from wild ancestors1 etc41 which can only become known to you through the studies that have been devoted to the science of zology by curious-minded investigators from the times of ,aristotle and ,pliny down to our own day1 when we have seen an ex-,president of the ,united ,states wandering adventurously through some of the remotest portions of the inhabited globe1 seeking fresh knowledge of1 and personal acquaintance with1 the rarer kinds of wild animals1 and hunting down in their native wilds great beasts which the ,csars used to admire from the security of the imperial seat1 high above the bloody sands of the ,roman arenas4 ,and this modern ruler1 after having laid down the political power intrusted to him by fellow citizens1 found no occupation so attractive as that of adding something to the growing stores of science4 ,illustration3 ,painting1 ,chas4 ,r4 ,knight4 7,american ,museum of ,natural ,history7 ,,the ,,little ,,eohippus4 ,,from ,,which ,,the ,,modern ,,horse ,,developed

fresco ,next1 your stomach1 awakened to its wants and needs by the restored circulation resulting from your lively exercises1 reminds you of what will be at the same time a pleasure and a means of sustained strength for body and mind1 your breakfast4 ,breakfast properly comes under the supervision of the science of physiology4 ,it is also suggestive of mechanics and physics1 since it has to do with the stoking of the furnace that keeps the bodily engine up to its work4 ,here you are face to face with a branch of science which you could no more safely neglect than an engineer or a fireman could neglect to learn the elements and principles underlying his critically important occupation4 ,one of the first sciences to be systematically developed was that of man's body1 including its structure1 or anatomy1 and its functioning1 or internal action1 physiology4 ,you will find that correct ideas on these subjects were slow in being developed1 yet even in the most ancient times men were shrewd and wise enough to understand the importance of knowing something about their own bodies1 in order to be able to take proper care of them1 and to deal with wounds and sickness4 ,it was an old saying that the proper study of mankind is man4 ,but that is a study which has two main branches4 ,the first covers the subjects of physiology1 anatomy1 medicine1 etc41 while the second relates to that even more intimate part of ourselves which has ever been a fascinating mystery1 and which we call the mind1 or sometimes the soul4 ,this is the theme of the science of psychology1 whose name comes from that delicate1 inscrutable spirit1 ,psyche1 the ,soul1 which plays like a flitting sunbeam through the magical atmosphere of ,greek mythology4 ,now1 this subtle and exquisite science1 often more poetic and mystic than scientific in its original character1 presents itself in its more sober and practical dress to you as soon as1 having finished your breakfast and prepared your bodily energies for the day's work1 you begin to meditate on the problems of the day opening before you4 ,when you went to bed1 perhaps your mind was agitated by some important matter of business through whose intricacies you could not clearly see your way4 ,you turned and tossed on your pillow1 and stated and restated the facts and arguments and lines of reasoning1 but all the while they became more obscure and entangled until at last1 in sheer exhaustion1 you fell into a troubled sleep4 ,but this morning1 to your immense surprise and gratification1 without any effort on your part1 and while you are occupied with other things--putting on your clothes1 hitting the ball1 playing with the dog1 eating your bacon and eggs1 or what not--suddenly the elusive clue or solution1 so vainly sought the night before1 presents itself plain before you4 ,in an instant1 in the twinkling of an eye1 the troublesome problem is solved1 as easily and naturally as water runs down hill1 and you are provoked at yourself for having been so dull and stupid as not to see it all before4 ,but not so fast6 ,you were stupid1 to be sure1 but it was not your mind's fault as you are now disposed to think1 but the trouble lay in your physical fatigue4 ,you were driving your brain too long without refreshment1 and it became like an engine whose oil cups are empty4 ,it could not receive and report the impressions of thought4 ,now this kind of experience comes many times to many men and women1 and it is the purpose of the book on psychology in this series to make everybody acquainted with the laws of the working of our minds through our brains4 ,yet1 how many of those who are frequently puzzled by such things are aware that there is a branch of science1 one of the most captivatingly interesting of all1 devoted especially to this subject8 ,by studying the volume on psychology you will get light on just such things as so greatly puzzled you1 and haunted you1 before the solution of your problem unexpectedly rose up1 as it were1 and stood plain before you on the breakfast table1 after having for twenty-four hours resisted your utmost efforts to master it1 or even to get an effective hold upon it4 ,it is unnecessary to speak of the immense importance to all human beings of a knowledge of the laws governing the manifestations of the mind1 by taking advantage of which they may get the most out of themselves with the least loss of time and expenditure of effort4 ,let us keep on further along the wonderful road of science on which your feet begin almost unknowingly to tread from the moment of your awakening1 and which they follow1 often just as unconsciously1 until you fall asleep at the close of another day2 while1 as we have just seen1 even when we are asleep our minds are not altogether inactive1 and may even secretly disentangle the puzzles of the day while our tired brains are restoring themselves with slumber4 ,perhaps you live in the suburbs of a city1 or far from the business center1 and have to take a considerable journey from your house to your place of work or business4 ,maybe you go by automobile1 or by street car1 or by a trolley route1 or take a commuters' train4 ,in any event1 whether you drive your own car1 or ride in one drawn by a motor or a locomotive engine1 you are brought face to face with the science of physics1 including1 of course1 not only mechanics1 but also1 in our own day1 electricity and magnetism4 ,if you glance at a steam locomotive1 puffing and blowing1 and then at a smooth1 silent electric motor drawing a long train1 and then at a swift automobile winding and turning with serpentine agility through crowds of slow horse-drawn vehicles--in all cases your memory must recall the long1 hard road by which these things were brought about1 and you must be lacking in intelligent curiosity if you do not resolve to know for yourself1 not only the history of these triumphs of human invention1 but the principles of action upon which they depend4 ,if you have a car1 it would be a good thing to drive it yourself and learn to take care of its machinery yourself1 for thus you would go far toward mastering the elementary principles of the science of mechanics1 which has done more than all other things combined to transform the face of the world we live in4 ,you cannot1 of course1 acquire all this knowledge by practical experience1 but by putting together what you observe with what you read in the volumes devoted to mechanics1 physics1 chemistry1 electricity1 etc41 you will find that every day is a school day for you in which you have learned something new1 useful1 and interesting1 and something1 moreover1 which every wide-awake person in this wide-awake age ought necessarily to know1 and can know by pursuing such a course as that just suggested4 ,your morning's ride to work will be transformed into a delightful intellectual experience if you prepare yourself by a little daily reading to understand the construction and manner of working of all the machines1 engines1 and mechanisms presented on every side to your inspection4 ,but machinery is not everything in life4 ,suppose that as you ride along your eye is caught by the great beauty of the flower gardens by the roadside1 their blossoms bright in the morning sunshine and sparkling with the yet undried dew1 as if sprinkled with diamonds4 ,perhaps your attention may never before have happened to be called so strongly to these objects1 and possibly you have hitherto remained almost unacquainted with the names and peculiarities of some of the most common plants and flowers4 ,but this morning1 for some accidental reason1 which may have a psychological origin1 you are particularly charmed with the brilliant sight1 and you resolve that you will be no longer ignorant of what could1 manifestly1 give you so much pleasure1 besides being of unquestionable usefulness4 ,when you return home you will take up the volume on botany1 and it may lead you into a realm of mental delight previously unknown to you4 ,if it is the springtime1 you may be interested by the sight of a tall1 graceful tree1 as lofty as a pine1 and as straight in trunk1 with many exquisite blossoms hanging from the pendulous stems on its great limbs1 fifty or more feet above the ground1 as if it were a flower garden in the air for the special delectation of the birds4 ,having never heard of a flowering tree outside the tropics1 you feel a keen desire to know what this one is1 and thus a way of introduction1 founded on keen1 personal interest1 is opened for you to the science of botany4 ,and few persons can take a ride1 or a walk1 anywhere in city or country or park1 without having attention attracted by some unknown flower or plant1 or tree1 and without becoming aware how much pleasure is lost1 and how much useful knowledge missed1 by lack of the easily acquired knowledge of these things1 which anybody can have by giving to it only that amount of time which would otherwise be wasted almost as completely as if the eyes were kept closed and the mind dismissed from its home in the brain4 ,more mysterious1 and not less fascinating than flowers and trees1 are the birds and insects that flit by on their own errands4 ,to explain them you have the volume on zology1 the science of animal life4 ,botany and zology together go far to revolutionize the ordinary man's ideas about the attractiveness of outdoor life4 ,for the cultivator of the soil1 whether farmer1 gardener1 or fruit grower1 botany1 of course1 is the queen of sciences--though he may not safely remain ignorant of the others mentioned1 which form a brilliant court for his queen4 ,in no direction has science lately proved itself so indispensable as in the application of botanical knowledge to the improvement of agricultural operations of all kinds4 ,in ,france1 always one of the richest of lands in this respect1 the government has since the war made special provisions for placing instruction in botany and plant physiology1 and the results of all advances in the science of the vegetable kingdom1 before the pupils of the primary as well as those of the secondary and higher schools4 ,botanical reading and study are encouraged in every possible way4 ,one of the most significant propositions for the extension of this educational reform consists in the suggestion that the schools in the country districts give much more attention to the various branches of botanical knowledge than the city schools do1 for the purpose not only of supplying instruction that will be of fundamental practical use to the young people who grow up on the land and are to make its cultivation their life's occupation1 but also of stimulating a love of the country for itself1 its scenes1 its atmosphere1 its society1 its amusements1 and its simple1 beautiful1 and healthful ways of life4 ,as your train1 or car1 rushes through a rock cut where the roadway has been carried1 without change of level or grade1 through the round back of a hill1 you may happen to see on the side walls of the excavation curious striations1 or cross checkings1 of the rock surface1 or alternate strata1 or layers1 of varying color and texture2 some composed of smooth-faced stone1 of a dark1 uniform color1 and others of coarse granular masses of variegated hue1 some of whose particles flash like microscopic mirrors in the glancing sunlight that grazes the top of the cut4 ,here1 then1 you are plunged into the wonder world of the geologist and the mineralogist1 the subject of one of the most interesting of our volumes4 ,that man must indeed be dull of intellect who does not feel a thrill of interest at the sight of these signs and inscriptions1 written by the ancient hand of nature in the rocks1 and telling1 in language far more easily decipherable than the hieroglyphics of ,egypt1 the story of the gradual growth of this round planet on whose surface we are confined1 like flies or ants1 as it rotates and revolves in empty space1 circling with us around a star1 ninety-three million miles away1 called the sun1 which saw the birth of our world and has ever since kept it warmed and lighted with its rays4 ,in those layers of rock in the railway cut you see the leaves of the book of geology1 infinitely older than the oldest scripture from man's hands1 and relating things that occurred in those far-off nights and mornings of time that flitted over the globe ages before the human stem had set off from the trunk of terrestrial life4 ,these geologic pages speak of occurrences in the building of the world that happened millions of years ago1 and millions of years apart1 though they have left marks and vestiges that the eye can discern as easily as if they had been the work of yesterday4 ,no observant person can ride twenty miles through the country1 especially in a hilly region1 without having the fundamental facts of geology continually before him1 and all that he needs in order to comprehend these things is a little preparatory reading1 accompanied and followed by intelligent thought and observation4 ,anybody to whom all rocks look alike1 and all hills the same1 needs a little awakening of the mind4 ,he is one of the persons had in view when this series was conceived and written1 and he has no occasion to feel in the slightest degree offended by such a statement1 for the simple fact that probably ninety-nine one-hundredths of his fellow citizens1 and they among the best in the community1 are just as unfamiliar with the plainest facts of geology as he is4 ,geology is not a difficult science to master in its main outlines1 and there are few more fascinating when once its drift is caught4 ,even the beginner in the reading of the volume on geology1 by seizing such chances of observation as every ride or walk affords1 may in a very short time acquire the ability to read the history of a landscape from its face1 to recognize the work of the glaciers in the great ,age of ,ice1 to see where ancient streams flowed1 or where molten rock has gushed up through the surface layers of the earth's crust1 and even to recognize on sight some of the fossils1 which are under everybody's feet in some parts of the country1 and which still retain the forms of animals some of which were among the primal inhabitants of the earth1 whose lines have died out1 while others1 though their individual lives expired tens or hundreds of millions of years ago1 bear in their fossilized forms a close resemblance to modern relatives and descendants whose generations still flourish in the living world in this twentieth century of man's latest historic era4 ,presently1 turning from the attractions of the outdoor world1 which seem just as entrancing the hundredth time you look upon them as they did the first time1 particularly if you have cultivated the habit not merely of noticing but of thinking and reading about them1 you take up the morning newspaper1 in which most of your companions of the car are already deeply buried1 and amid the political news1 the personal gossip1 the inevitable exploitation of the deeds of criminals1 the foreign intelligence1 and the social gossip that falls under your eyes1 your attention is caught 7this is an actual happening of not long ago7 by the headline3 ,john ,daniel1 the orang-utan1 is dead4 ,this sounds odd4 ,there has been no animal's obituary in the papers since ,barnum lost his biggest elephant1 and bequeathed its skeleton to science4 ,you read further and find an interview with a professor about the human relationships1 or apparent relationships1 of the anthropoid apes1 of whom ,john ,daniel would probably have been the acknowledged king if his relatives of the woods could have understood the regard in which he was held by his white-skinned and clothes-wearing jailers4 ,you will probably cut out that paragraph and put it aside for further consideration1 remembering that there are at least three volumes in your ,popular ,science set at home1 that on zology1 that on geology1 and that on anthropology1 in which there will be an abundance of interesting and authoritative matter bearing on this most important subject--for important you will consider it now that the death of a kind of caricature of humanity in the zological garden that had so long amused the children as well as their elders with its humanlike motions1 habits1 looks1 and pranks1 has suddenly brought the whole question up among the news of the day1 affording you a new light on a matter which you had hitherto thought to belong exclusively to the field of the professors of zology and their students4 ,hereafter you will disposed to take a broader view of all these things1 and will be in a better position to understand and enjoy the discussions of learned scientists when they are interviewed by newspaper men on subjects of this kind4 ,the inquiring spirit of the time requires this concession even if in your private opinion there is no real relationship between men and apes4 ,and1 without regard to any such questions1 you will find the volume on anthropology immensely interesting and informing4 ,finally1 as your morning's trip comes to an end1 your attention is recalled from the natural to the mechanical sciences4 ,you descend from your car or train1 to go to your office4 ,your now fully awakened mind1 alert to all the scientific relations of everything about you1 can no longer keep from dwelling upon the underlying meanings of this marvelous display of realized human dreams4 ,with the speed of the wind you are carried deep under the city's pavements1 inclosed in a little flying parlor1 in the midst of an artificial subterranean daylight1 far beyond the reach of the solar rays1 emulating the self-luminous creatures of the deep sea bottom2 or you go shooting past the window of third1 fourth1 and fifth stories1 or even above the levels of roofs1 and you cannot but reflect and marvel that electricity does it all2 electricity1 that strange imp with blue star eyes no bigger than pin points1 and a child's crown of little crinkling1 piercing rays1 which seemed so amusing when you were at school in the old days of frictional electric machines1 when it was a great joke to give the cat a shock and see her flee with a squall1 her hair standing on end in spite of herself4 ,but now electricity has become a giant of unrivaled and terrific power1 spurning the heavy-limbed ,brobdingnag1 steam1 from its swift path1 and fast making the world all its own--except its master1 man1 who is still1 however1 half afraid of his new and all-capable servant4 ,illustration3 ,,exhibition ,,of ,,copies ,,of ,,prehistoric ,,paintings ,,from ,,the ,,caverns ,,at ,,altamira1

,,times ,this modern genie of limitless power1 conjured out of his deceptive bottle1 can do the smallest as well as the greatest things for you4 ,when1 upon reaching your office1 you telephone to your wife that ,mr4 ,blank will be home to dinner with you1 you cannot form the slightest idea of how the miracle of distant speech is accomplished unless you are either an electrician yourself1 or have read intelligently upon the subject of the applications of electricity to the motivation of all kinds of machinery1 a subject to which an entire volume is devoted in our series4 ,it would be a kind of shame and reproach to an intelligent man to be ignorant of the way his telephone works1 and of the simple scientific principle on which it is constructed4 ,if telephones1 and such things1 were products of nature and grew on trees1 we might be excusable for not knowing exactly their secret2 but being made by men1 with the same limitations as those that circumscribe us all1 we ought at least to understand them4 ,thus1 by a simple review of the series of common happenings that arrive every day to everybody1 we perceive how intimately and indissolubly the various branches of science treated of in this compact library of science1 are linked with all that we do1 including our most unconscious acts and our most habitual subjects of thought4 ,we have taken for illustration the morning history of a person supposed to live amid urban or suburban surroundings4 ,equally illuminating would be that of an inhabitant of a village or a rural district1 and even more suggestive in many respects4 ,the dweller in the country is brought into closer association with the infinitely changing aspects of nature than the city dweller enjoys4 ,the simplest incident in the life of a person living on a farm may be the beginning of a thread of connection leading1 like the clue of a labyrinth1 into the heart of some of the most marvelous departments of science1 and resulting in a mental revolution for the fortunate person who follows out the clue under such guidance as these volumes afford4 ,the writer has remembered from boyhood the indelible impression made upon his mind by the finding of an ,indian arrowhead in a recently ploughed field4 ,the shapeliness of the beautifully chipped piece of flint1 almost as translucent at the edges as horn1 the delicate tapering point which1 as if by miracle1 had remained unbroken probably since colonial times1 the two curious little ears carefully formed on each side of the flat triangular base to facilitate attachment to the head of the arrow1 and the thought1 suggested by older persons1 that this weapon might actually have been used in some midnight attack on a white settlement1 made more terrifying by the frightful ,mohawk war whoop and the display of the reeking scalps of human victims in the glare of burning stockade and cabins--all these things bred a keen desire to learn the particulars of the history of the red warriors of the ,five ,nations1 the ,romans of the ,new ,world1 and also to know something about the life and customs of this strange1 savage race of mankind which continued to live in an age of stone on a continent that had never known civilization4 ,no volume like that on the history and development of man in this series existed at that time2 but if such a book had existed and had fallen into the hands of the finder of the arrowhead1 it would surely have fascinated him more than ,robinson ,crusoe did1 because a boy can distinguish as readily as a grown person the superior interest of the true over the pretended1 provided that the true possesses the real elements of romance4 ,so1 too1 the writer remembers having an interest in mineralogy awakened in his mind1 never to be obliterated1 by the sight of another plowed field1 in the southern skirts of the ,adirondack ,mountains1 whose freshly turned furrows glittered in the sunshine with thickly scattered quartz crystals1 some of the larger and more perfect of which blazed across1 the whole breadth of the field1 like huge diamonds1 and made the heart of the finder beat with an excitement akin to that of the discoverer of a ,koh-i-noor4 ,there were also some very curious stone buttons which one could break out with a hammer from slate rocks along the ,schoharie ,creek1 and which1 when cracked open1 were found to be composed of pyrites that resembled pure silver--and sometimes gold--freshly broken4 ,now1 things of this sort are always attracting the attention and awakening the curiosity of children living in the country1 but the real pleasure and instruction that they might afford are usually missed because of the lack in the family library of popularly written books on the natural sciences--a lack that we are trying to supply4 ,for city children and their elders1 whose eyes are constantly greeted1 not by hills1 creeks1 ponds1 rivers1 woods1 and fields1 but by sky-aspiring buildings1 railroads elevated on stilts1 multiple-decked suspension bridges1 electric power houses1 tunnels that form a second city underground1 and the thousand marvels and splendors of electric illumination at night1 the volumes on physics1 mechanics1 and electricity and magnetism have a more immediate interest and value4 ,what the children learn about these things in school is far from sufficient to satisfy their curiosity4 ,they need books at home to guide their inquiries as well as to answer them4 ,only by that means can the diffusion of scientific knowledge1 and the popularization of the scientific method of getting at the truth and the meaning of things be thoroughly effected4 ,science1 as its history plainly demonstrates1 progresses most rapidly only when a great number of minds have been led to concentrate their powers upon its problems4 ,great genius1 it is true1 rides over obstacles2 yet consider how much further its energies might have carried it if the obstacles had been more or less completely removed in advance4 ,many a young man has been led to a brilliant career1 to the great advantage of his country and his time1 as a result of the interest awakened in him by the clear statements of a popularly written book on some branch of science4 ,one of the difficulties that persons unfamiliar with certain branches of science encounter in reading about them arises from the excessive use of technical terms1 the lack of simple illustrative examples1 and also1 sometimes1 a lack of sympathetic appreciation of the reader's difficulties4 ,it has been a special object of this series to avoid this trouble4 ,ordinary textbooks are prepared for students in school and are intended to be supplemented by the personal instruction and guidance of a teacher1 standing at the pupil's elbow1 or readily approachable4 ,but the reader who wishes to inform himself upon some progressive branch of science after his school days are over needs to have the teacher included in the book itself4 ,then1 too1 there are many persons who have no comprehension of the great and gratifying power that a knowledge of some of the elementary principles and formulas of science bestows upon anybody who may take the little trouble necessary to master them1 a trouble that does not imply a long course of scientific study4 ,the man in the street1 if he possesses these easy-working keys to knowledge1 can verify for himself some of the calculations of scientists which1 if he did not know how they were done1 would always remain for him in the category of the mysterious achievements of genius4 ,to illustrate1 let us take a simple example--that of the ,newtonian law of falling bodies4 ,many persons would assume on the face of it that there was nothing in this law that could have a particular interest for them4 ,but let us see4 ,you will find in the volume on physics that the law is stated thus3 ,s gt1 i4 e41 ,s equals one-half of the product of g multiplied by t squared4 ,as you look at it you would1 perhaps1 as soon think of picking up a complicated tool and trying to use it for some ordinary purpose4 ,nevertheless1 let us try4 ,s in the formula means the space or distance traversed by the falling body1 g means the velocity that the force of gravity imparts in each successive second to the body1 and t means the time elapsed during the fall4 ,what the formula tells us1 then1 is that if we observe the time during which the body is falling1 and then square the number of seconds involved 7multiply the number by itself71 multiply this square by g1 which is represented practically everywhere on the face of the earth by the number #cb1 and finally divide the whole by #b1 we shall have the distance that the body fell4 ,this distance will be in feet1 since the number #cb1 representing g1 is in feet4 ,now1 it might be a matter of life and death1 or at any rate of mental discomfort against quietude of mind1 to have that rule in memory and to be able to apply it4 ,for instance1 you are on your vacation and stopping in a strange hotel1 where they have put you in the top story4 ,on looking out of the window you are dismayed at finding no fire escape1 or other appliance of safety1 so that your only resource in case of fire would be to make a rope out of the bedclothes and let yourself down with it4 ,but1 how far is it to the ground8 ,how long should the rope be8 ,are there sheets enough on your bed to furnish it8 ,the little formula about falling bodies will answer the question for you in five minutes4 ,first1 you let some small solid object drop from the window1 and note by your watch1 or by counting seconds1 which everybody ought to teach himself to do1 how long it takes to reach the ground4 ,you repeat the experiment two or three times to make sure4 ,say the time comes out three seconds4 ,very well1 now apply the rule3 ,the square of #c is #i1 and #i multiplied by #cb gives #bhh1 and dividing by #b you have #add feet for the height6 ,it is to be feared that your bedclothes rope would not be long enough2 you had better send to the office for something to supplement it4 ,but if the time of fall should be only #b seconds1 which is more likely1 except in skyscraper hotels1 then the calculation would give you #fd feet for the height1 which you might manage with the aid of the bedclothes4 ,illustration3 ,,models ,,of ,,gutenberg',s ,,printing ,,presses ,the models show three stages of development1 the first of them at the right ,illustration3 ,,benjamin ,,franklin',s ,,printing ,,press ,the original is now in the ,national ,museum at ,washington ,this is only a single example among many that could be given to show the usefulness and interest of many of the formulas of science which the ordinary reader looks upon as beyond the reach of any person whose occupation leads him another way4 ,but cases of equal simplicity could be found in connection with the subjects of electricity and magnetism1 chemistry1 medicine1 physiology1 etc4 ,sometimes it happens that a technical word contains its own definition and explanation in a nutshell4 ,a striking instance of this will be found in astronomy1 in the word light-year4 ,the meaning of this word stands forth on its face--it evidently expresses the distance that light travels in the course of one year4 ,now1 since it is known by means of direct measurement that light goes at the rate of #ahf1cjj miles per second1 manifestly a light-year must be equivalent to an enormous number of miles4 ,in fact that number1 roundly stated1 is no less than #e1hfj1jjj1jjj1jjj4 ,but to what marvelous regions of thought such a term opens the way6 ,yonder star is #b1jjj light-years distant from the earth2 then its light-waves now entering your eyes left it when ,julius ,csar was conquering ,gaul1 and have been speeding on their way to the earth ever since6 ,another star is found to be #e1jjj light-years distant2 then the light by which you now see it started from the star when ,abraham set out from ,ur of the ,chaldees to settle in the ,holy ,land1 and has not found a resting place anywhere in boundless space until just now when its tiny waves break and expire on the retina of your eye6 ,such treasures of knowledge and tonics to thought are scattered all through the volumes of this set1 the purpose of whose publishers1 editors1 and writers has been to accumulate such things in small compass and in crystal clearness1 for the use not only of those who1 after their school days are over1 still wish to keep abreast of the progress of science in all its branches--as everyone should strive to do in this most scientific of all ages--but also for those who have hitherto not had the time1 or the opportunity1 or perhaps even the desire1 to make themselves at home in the house of science4 ,it may be well to add a few words on the interrelation of the different subjects treated in the various volumes of the series4 ,this will suggest to the reader himself the best order in which to take up the reading of the books4 ,naturally he will desire to obtain both a clear general view of the whole field of science1 and also more detailed acquaintance with its special parts1 the amount of detail depending upon his particular interest in a subject4 ,for the first purpose the preferable way would be to run first over the brief account that follows in this volume1 of the history and development of science in general1 and then to take up the simpler and more easily grasped branches4 ,but it should be firmly kept in mind that1 fundamentally1 science is one1 having in all its branches but one aim and object1 viz41 the ascertainment and demonstration of the exact truth of things as far as human capacities are able to reveal and comprehend such truth1 and also but one method of procedure1 which is the method of common sense trained to the utmost attainable exactitude in observation and the greatest possible clearness and precision of reasoning4 ,science properly so-called confines itself to things that are subject to observation by the senses and to verification by repeated observation and experiment1 while its reasonings and predictions are based entirely upon the unvarying sequence of the phenomena of nature1 as they display themselves before us4 ,science is just as one and inseparable as life1 or as an organic being1 and its divisions no more imply lack of unity than do the various organs and limbs of an animal1 or a tree1 or the different structural parts of a building4 ,astronomy is not entirely independent of geology1 nor geology of botany1 nor botany of chemistry1 nor any of these of physics1 nor physics of electricity and magnetism1 nor the last of physiology and medicine4 ,accordingly the question where to begin in studying science is not one that can be answered in the same way for everybody4 ,but the spirit is the same in all the branches4 ,perhaps the best general indication of the order in which a person who has no predilection for any one branch of science should take up the various parts is afforded by their historic development4 ,this was a result of the natural reaction of man's mind to its surroundings4 ,the things nearest to him1 and most immediately important1 first attracted his attention4 ,the broadest division would be into the science of things on the earth's surface2 the science of things above the earth1 in the air and the sky2 and the science of things within the earth1 concealed from immediate view4 ,if we take these in their order they naturally subdivide themselves as follows3 #a--,,things ,,on ,,the ,,earth--,,explained ,,by 7a7 ,anthropology1 the ,science of ,man and ,his ,ancestors1 treating of his nature1 origin1 development1 division into races and tribes1 society1 industry1 etc4 7b7 ,zology1 the ,science of ,animal ,life1 treating of the lower animals1 and of animal life in general as distinguished from the kingdom of the plants1 although the related science of biology deals with both plants and animals1 its special subject being the phenomena of life in its widest sense4 7c7 ,botany1 the ,science of ,plant ,life4 7d7 ,geography1 combined with ,physiography1 the ,science of the ,face1 or ,superficies1 of the ,earth1 dealing with lands and seas1 rivers and mountains1 political divisions1 etc4 ,this is covered in our series by the volume on ,physiography4 7e7 ,in this compartment several branches of science may be grouped1 since they are all the product of study of things encountered on the earth's surface4 ,they are3 ,physics1 the ,science of the ,forces of ,nature1 dealing with the laws of the inanimate world around us1 including the phenomena relating to solid1 liquid1 and gaseous bodies and substances4 ,chemistry1 the ,science of ,matter and ,its ,changes1 dealing with the atoms and their constituents1 and with the combinations of atoms into molecules to form the various chemical elements1 etc4 ,electricity and ,magnetism1 the ,science of ,power1 fundamentally underlying all other branches1 and through its investigation of the nature of the constituents of atoms--the electrons--going deeper into the constitution of things than chemistry itself4 ,in fact this science1 in some respects1 blends with chemistry1 although it is quite separate when it deals with the mechanical developments of electromagnetism4 ,medicine1 the ,science of ,health1 ,physiology1 the ,science of the ,body1 ,psychology1 the ,science of ,human ,behavior1 ,mechanics1 the ,science of ,machinery1 etc41 also naturally fall into this category of ,things on the ,earth4 #b--,,things ,,above ,,the ,,earth--,,explained ,,by 7a7 ,astronomy1 the ,science of the ,heavenly ,bodies4 7b7 ,meteorology1 the ,science of the ,atmosphere1 rains1 winds1 storms1 fair and foul weather1 the changes of the seasons1 and essentially related to the new and fast developing art of aerial navigation4 #c--,,things ,,within ,,the ,,earth--,,explained ,,by 7a7 ,geology1 the ,science of the ,earth's ,crust1 or shell2 which also deals with the various stratifications of the rocks1 superposed one above another1 and containing in the shape of fossils1 and other marks1 a wonderful record of the character and development of the living forms that have inhabited the earth during the long ages of the past4 ,of course some of the phenomena dealt with by geology are manifest on the earth's surface1 and others1 like volcanoes and earthquakes1 hot springs and geysers1 are partly subterranean and concealed from sight and partly evident by their effects on the surface4 7b7 ,closely associated with ,geology are ,mineralogy1 the ,science of the ,constitution and ,structure of ,rocks and of ,mineral and ,metallic substances2 ,vulcanology1 the ,science of ,volcanoes1 and of earth disturbances in general2 and the ,science of ,mining1 which has several branches1 and forms the basis of enormous industrial developments4 ,it is manifest1 as before said1 that the reader must be his own best judge as to the precise order in which to take up the perusal of the volumes in which this immense mass of scientific knowledge is presented4 ,but1 where there is no predisposition to choose one subject rather than another1 or where there is a desire to follow1 as nearly as may be1 the natural line of development of human knowledge1 it would be well to take first1 after the history1 the volume on astronomy1 a science that from the beginning has had a peculiar power to awaken intellectual curiosity2 then that on anthropology2 then the various so-called natural history subjects1 leaving the mechanical and the more technical subjects for the last4 ,or1 the reader might first take up the subjects of personal importance to every human being--,medicine1 the ,science of ,health2 ,physiology1 the ,science of the ,human ,body2 ,psychology1 the ,science of the ,mind--every one of which is essential to the proper care and preservation of life2 and afterward study the other branches in the order already suggested4 ,illustration3 ,garrett ,p4 ,serviss ,,chapter ,i ,,history ,,of ,,science ,the romantic history of science shows how the discoveries of the greatest human minds1 slowly operating since the remotest times1 have made possible our present-day civilization4 ,few studies are worthy of greater attention2 no other department of knowledge affords more real pleasure4 ,whoever clearly understands the history of science possesses intellectual advantages over those who are ignorant of the causes that have led to the establishment of the basic principles of our modern industrial arts and applied sciences4 ,standards of comparison are furnished by the history of science which illuminate many of the wonders of to-day1 develop alertness of mind1 and afford a never-ending train of suggestions for thought4 ,the term science means knowledge4 ,it was derived from the language of the ,romans4 ,it is well to have a clear idea of the meaning of the word4 ,everyone knows that it has to do with certain kinds of knowledge2 few know the particular kinds it embraces4 ,it does not mean the mere knowledge of a single fact4 ,it does not mean a knowledge of something which has to be done4 ,long before science was born1 our early ancestors observed many isolated physical1 philosophical1 and religious facts4 ,they knew that day followed night1 that the stars moved1 that every day the sun progressed over the arch of the heavens4 ,such facts did not constitute science4 ,what we know as science began when man commenced to compare one fact with another1 to classify phenomena1 and to arrange his knowledge systematically4 ,order1 method1 system1 are basic principles of science4 ,the best description would1 therefore1 appear to be systematized knowledge of any kind which had been gained and verified by exact observation and correct thinking4 ,the whole field of human knowledge is now methodically formulated and arranged into rational systems4 ,modern science may1 therefore1 be said to embrace all our exact knowledge4 ,its province is enormous2 its subdivisions are limitless4 ,science takes no account of knowledge which is not exact4 ,many people acquire valuable information which they profitably use in business1 but which they are unable to communicate or describe to others because they do not actually understand it4 ,farmers and flower growers often possess important practical knowledge of facts which are embraced by the principles of the sciences of agriculture1 botany1 and biology4 ,but their practical knowledge is not true science4 ,it is rather like an artist's intuitive impulse4 ,it is not the result of scientific analysis1 and there is no tangible1 communicable residuum4 ,there could be no science if men did not discover principles of knowledge which can be communicated to1 and made available for use by others4 ,scientific knowledge must be stripped of all traces of emotionalism and personal convictions4 ,true science is1 therefore1 depersonalized knowledge4 ,the history of science shows how our exact knowledge has been developed along irregular paths but with progressive advances4 ,there have been long periods during which little apparent progress was accomplished1 which have been succeeded by others made memorable by brilliant discoveries4 ,we must constantly bear in mind that many of the truths generally accepted to-day were doubtful or novel theories at some previous period4 ,the history of science shows the enormous mental effort expended in testing and developing what now appear to us as commonplace truths4 ,basic principles like those of algebra1 geometry1 and the planetary motions were tested during several thousand years before they were finally accepted as true4 ,the human intellect at the dawn of history was similar to what it is to-day4 ,but it was not exercised as we exercise ours because it did not have adequate materials and opportunities4 ,for the same reason science made slower progress in early times than it does now4 ,progress is cumulative4 ,each advance helps that which follows4 ,the functions of a scientist are to struggle against individual views1 and to provide an explanation of phenomena which may be accepted as true by other minds4 ,ascertained facts must be classified and then sequence and significance recognized from an unbiased viewpoint4 ,the history of science is the written record of countless experiments1 theories1 and experiences of mankind which have been submitted to the tests of scientific methods4 ,while it is true that science embraces all knowledge its real scope is limited to knowledge which is reducible to laws and can be embodied in systems4 ,the human mind unites all knowledge by a single thread1 but we have to chart and map it into larger and smaller divisions which we define by the methods1 basic concepts1 and plans used in developing them4 ,we may now see how it is that the boundaries of any science are merely approximate4 ,the general grouping of the sciences is likewise approximate4 ,the first large group includes the abstract1 or formal1 sciences such as mathematics and logic4 ,the other great group comprises the concrete sciences dealing with phenomena as contrasted with formal relationships4 ,chemistry1 biology1 physics1 psychology1 and sociology belong to the concrete group4 ,at the beginning of history man is discovered observing the great phenomena of ,nature and struggling to learn their laws and to explain them4 ,religion is both emotional and intellectual1 and through these qualities it attracted primitive man while he was attempting to gather light on the riddles of the world4 ,it was through religion that science was born4 ,recent researches into primitive beliefs have shown in a surprising manner the psychological unity of man4 ,in all parts of the world1 in all periods of history1 and under all conditions1 the minds of men1 in their natural reactions against the basic factors of existence1 operate in similar ways4 ,there is a remarkable resemblance in the mental processes of men4 ,the laws of thought appear to work automatically in all men4 ,the minds of prehistoric people worked like those of men to-day4 ,the impressions of the senses appear to be interpreted in similar ways by all peoples4 ,here is the explanation of the numerous resemblances we find in national histories1 national folk lore1 and national religions4 ,they differ much in innumerable details1 but possess many resemblances in their great fundamental conceptions4 ,normal man has always been religious4 ,mankind has always assumed definite attitudes toward the universe and this has resulted in the universality of religion4 ,early men the world over appear to have been as eager to learn the keys to the riddles of the universe as was the boy ,longfellow sang about in the following stanzas3 ,nature1 the old nurse1 took ,the child upon her knee1 ,saying3 ,here is a story-book ,thy ,father has written for thee4 ,come wander with me1 she said1 ,into regions yet untrod2 ,and read what is still unread ,in the manuscripts of ,god4 ,and he wandered away and away ,with ,nature1 the dear old nurse1 ,who sang to him night and day ,the rhymes of the universe4 ,and whenever the way seemed long1 ,or his heart began to fail1 ,she would sing a more wonderful song1 ,or tell a more marvelous tale4 ,modern science has developed from this instinctive human desire to read ,nature's story-book and understand her marvelous tales4 ,early struggles of mankind taught that human behavior must be regulated in accordance with rigid moral laws4 ,this promoted the primitive social processes which were early concerned with religious beliefs as well as with magic and medicine4 ,two of the earliest beliefs universally accepted were that we possess souls and that our personality persists after death4 ,these basic principles of faith have caused extremely beneficial results to follow in the development of knowledge4 ,some of the ,american ,indians and other primitive peoples of to-day still live in the belief that the heavenly bodies1 the sky1 sea1 and earth1 as well as plants1 animals1 and men1 all belong to a vast system of all-conscious and interrelated life1 in which the degrees of relationship are distinguished by the degrees of resemblance4 ,religious beliefs were developed from struggles to conceive the inconceivable and discover the infinite4 ,religions led to studies of mysteries and ceremonies and rites4 ,magic developed and this also had its customs1 dogmas1 and rites4 ,the difference between magic and religion was that the magician was consulted by his personal friends1 whereas the holders of religious beliefs had a common bond uniting them in one strict form of worship4 ,magic was not systematized1 while religion was a unified system of beliefs and practices relative to sacred things1 and chiefly to the regulation of moral concepts and conduct4 ,the intimate association of religion1 magic1 necromancy1 and science continued until the early ,greek era4 ,there were many temples erected in ,greece and dedicated to sculapius1 the god of medicine4 ,cures were believed to be effected through the valuable offerings made to the god by patients and their friends4 ,it was thought that the ways to health would be indicated to them by the god through dreams4 ,recent investigations of the representative ceremonial rites of the aboriginal peoples of ,australasia and of ,north and ,south ,america have yielded a remarkably rich fund of information on the causes and conditions which operated in prehistoric eras in developing the mental1 moral1 and physical sciences4 ,some of the most romantic stories ever developed by the human intellect are to be found in recent scientific works dealing with the history and principles of the tribal customs1 ceremonies1 and religious rites of primitive peoples4 ,the early chapters in the history of man's mental development and the evolution of science from distant origins in mystic forces1 through magic and necromancy to religion and philosophy1 must give abundant pleasure to all thoughtful persons by showing how it came that the high state of civilization now attained was brought about by slow processes1 operating through immense periods of time and blossoming only during the past two or three thousand years4 ,a study of these stories cannot fail to show how intimately science has been associated with religion1 why every normal individual is essentially religious1 and why the continuation of our civilization1 and the very existence of the human race1 are absolutely contingent upon the recognition of the moral laws1 in the future as in the past4 ,the history of science establishes the fact that moral sanctions1 which require religious ceremonies to keep them vital1 are the essential bases of human progress4 ,,chapter ,,ii ,,primitive ,,man ,,and ,,early ,,civilizations ,the development of scientific history has not followed a uniform course4 ,progress has been rhythmic4 ,there has been always a reaction coming in the steps of brilliant discoveries4 ,periods of feverish experimental activities have been succeeded by others during which little apparent progress was made4 ,such dull intervals seem to have been necessary for developing1 formulating1 classifying1 and testing the innumerable details and inferences that the discoveries of the active periods produced4 ,while mankind in general has contributed to the total of our intellectual treasures1 some races have been more active in this way than others4 ,for this reason it is advisable to briefly survey the more recent discoveries about the ancestors of existing peoples4 ,indo-,malaysia1 parts of central ,asia1 and the valleys of the ,tigris and ,euphrates rivers in ,mesopotamia are variously credited with having been the cradle of the human race4 ,it should be understood1 however1 that we are only permitted to speak authoritatively of existing races1 because the land forms of the earth have undergone such remarkable changes that we can know little definitely about the earlier periods of human history4 ,for the purposes of the history of science1 while bearing in mind these qualifying suggestions1 we may accept the statement that man's ancestors originated in proximity to ,india4 ,it was around the waters of the ,persian ,gulf that the earliest known civilizations arose4 ,the people who founded them came from central ,asia4 ,they had reached a considerable degree of culture1 which suggests that they themselves came from earlier centers of civilization4 ,the study of prehistoric antiquity is termed archology4 ,its principal periods have been divided1 for convenience1 into the ,stone1 ,bronze1 and ,iron ,ages4 ,each of these is distinguished by the substances used for tools4 ,in the ,stone ,age men used stone spearheads1 arrows1 and knives1 whereas in the ,iron ,age similar things were made of iron or copper4 ,the science of mankind is known as ,anthropology4 ,it deals with the innumerable steps in the evolution of mankind from remote periods1 and with the primitive development of the arts1 sciences1 and religion4 ,yet it is one of the youngest of the sciences4 ,one of its essential teachings is that heredity and racial predispositions play1 and always have played1 more important parts in man's evolution1 and in the development of civilization1 than environment and education4 ,hereditary tendencies1 such as the religious1 moral1 and sthetic instincts have been indispensable in preserving and developing all the races of mankind4 ,moral discipline has been the chief factor in self-control1 and therefore in civilization4 ,it is because the moral sense has proved so beneficial to the human race1 and is the most powerful of our instinctive desires1 that mankind always has been and must be religious4 ,it controls man's knowledge1 desires1 and will1 and has dominated the race since our early ancestors began to think4 ,when we recognize this fact we can readily see that anything which tends to oppose the moral or ethical sanctions1 or detract from religious beliefs1 is injurious to civilization and human progress4 ,the histories of religion1 ethics1 and sthetics plainly develop the rles which have been played by moral self-discipline in the protection and development of mankind1 as well as of knowledge and science4 ,the moral control of individuals acts also upon society generally1 and upon whole racial and national groups4 ,the ethical ideals assist each individual mind to realize its own end and at the same time tend to influence the tribal and social mind to attain a common end4 ,this great moral1 instinctive force1 which has played such an immensely valuable part in developing civilization and science1 is known as the human social and national conscience4 ,it acts both individually and collectively4 ,european races have been divided into classes corresponding to the prevailing cephalic indices4 ,the longheads are grouped as the ,nordic1 or ,baltic1 subspecies1 because they were formerly numerous around the ,baltic countries4 ,people of this group are distinguished by tall statures1 fair skin and hair1 good physique1 and light colored eyes4 ,these peoples include the ,scandinavians1 ,anglo-,saxon1 and certain important ,teutonic groups1 as well as ,asiatic peoples who are known as the ,aryans4 ,illustration3 ,copyright1 ,ewing

#aiba ,illustration3 ,u4 ,s4 ,,army ,,dirigible ,,on ,a ,,transcontinental ,,flight ,the most important rles in the development of modern civilization1 art1 industry1 and science have been played by representatives of the ,nordics4 ,the ,iberian1 or ,mediterranean1 subspecies1 ranks next in importance4 ,the peoples of this great racial division originally occupied the countries between the northern ,atlantic coast of ,africa and the confines of the areas of the ,nordics around the northern provinces of ,france4 ,they spread down the ,mediterranean and over large areas in ,asia4 ,their skulls are long1 but differ from those of the ,nordics in their absolute size4 ,their stature is lower1 and weaker than that of the ,nordics1 while their hair1 eyes1 and skin are dark or black4 ,the ,welsh1 the ,moors1 and the early ,greeks are chiefly classed with the ,mediterranean group4 ,the ,carthaginians1 ,phnicians1 ,egyptians1 and ,etrurians were members of it4 ,the roundheads comprise the ,alpine subspecies4 ,this is the strongest numerical group to-day4 ,it is characterized by small round heads1 short bodies1 dark hair1 and dark eyes4 ,it is of ,asiatic origin and includes the ,slavs1 modern ,greeks1 ,italians1 ,germans1 ,austrians1 ,swiss1 the pre-,nordic ,irish1 ,french1 and ,belgians4 ,the first ,alpine invasion of ,europe began about #aj1jjj ,b4 ,c4 ,there were many subsequent ones through the plateaus of ,asia ,minor1 the ,balkans1 and valley of the ,danube4 ,they reached ,england about #ahjj ,b4 ,c41 and formed small colonies in ,ireland1 the descendants of which now call themselves ,celts and are clearly distinguished by the characteristic ,alpine indices4 ,this race is now so well acclimatized in ,europe that most of its ,asiatic traces have been lost1 and its round skulls and dark eyes and hair are the only reminders of its ,mongolian origin4 ,members of each of these three great racial groups of mankind have throughout the ages contributed to the development of the sciences and arts4 ,the ,nordics began to appear in ,european history as agricultural tribes1 speaking ,aryan languages1 like ,celtic and ,welsh1 who swept down from the north and pushed the earlier settlers back through their irresistible arms1 which were made of bronze and later of iron4 ,the earlier settlers were still furnished with arms and implements of the ,stone ,age4 ,there was a much older intellectual people than the ,nordics settled in ,europe4 ,the people of this race1 about whom we have learned through recent archological researches1 are known as the ,cro-,magnons4 ,they lived between #be1jjj and #aj1jjj ,b4 ,c4 ,their skulls were distinguished from those of the ,nordics by their pronounced cheek-bones and broad faces4 ,their culture1 as their favorable cephalic index would suggest1 was of a high character4 ,numerous drawings and art works of theirs1 which have been preserved1 place them among the world's superior peoples4 ,soon after the settlement of the ,cro-,magnons in ,europe1 and their intermarriage with the earlier settlers1 their physical development and stature began to decline4 ,they were finally absorbed and destroyed by the inferior peoples among whom they dwelled4 ,their disappearance1 like that of the ancient ,greeks1 who appear to have been the most intellectual people the world ever produced1 shows how the upward development of human physical and intellectual qualities is constantly injured by the contacts of superior and inferior races4 ,the scientific discoveries made prior to the ,iron ,age1 or about #bjjj ,b4 ,c41 were not numerous4 ,the struggle for life was so intense that few had opportunity for contemplation and philosophic reflection4 ,it was subsequent to the discovery of the basic principles of metallurgy1 in the ,iron ,age1 that science began rapidly to advance4 ,the benefits bestowed upon mankind by the employment of metals reduced the sharpness of life's struggles1 permitted and instigated reflection1 and provided means for experimentation4 ,modern history begins with the peoples of ,mesopotamia4 ,there were cultured peoples east of the ,tigris and ,euphrates1 in ,persia1 ,india1 ,mongolia1 ,tartary1 and ,china before the founding of ,babylon4 ,but we are more instructed about the ,babylonians and ,assyrians than about earlier ,asiatic races4 ,the ,babylonians and ,assyrians appear to have originated in central ,asia and to have migrated to ,arabia about #aj1jjj ,b4 ,c41 and perhaps earlier4 ,they were well settled in ,arabia before the ,egyptian pyramids and other ,semitic memorials were planned4 ,they brought with them from the farthest ,orient many important contributions to civilization and culture1 and developed many others4 ,these were religious1 philosophical and keen commercial peoples4 ,they shaped the organization of modern religions4 ,the ,babylonians reduced the world of gods to a single system with classifications distinguishing between major and minor deities1 and between those of heavenly1 or stellar1 and earthly habitats1 and those of time and space4 ,they developed many religious myths of the ,creation1 the ,flood1 ,paradise1 and others which were subsequently embraced by other religions4 ,both the ,babylonians and ,assyrians composed beautiful hymns1 prayers1 parables1 and religious tales1 and had numerous elaborate religious customs1 rituals1 ceremonies1 and festivals conducted by priests1 nuns1 and acolytes4 ,anu1 or ,anum1 the ,god of ,heaven1 was the principal ,babylonian deity1 while ,ashur was the leading god of the ,assyrians4 ,religious studies and rites occupied a large portion of the time of these peoples and1 consequently1 their temples1 monasteries1 schools1 and other religious buildings were large and numerous4 ,their architecture was elaborately artistic4 ,this was one of their incentives to scientific invention4 ,they made important discoveries in all the basic physical sciences1 like chemistry1 physics1 metallurgy1 and mathematics1 to enable them to improve their buildings and to embellish them with paintings1 pictorial tiles1 and fancy metals and textiles4 ,they had excellent professional men1 artists1 jurists1 bankers1 contractors1 and scientists4 ,they were fond of literature and founded extensive libraries4 ,music and musical instruments were very popular with them4 ,their cuneiform writings1 as disclosed by numerous beautiful stone and porcelain tablets which have come down to us1 were excellently done4 ,the fragments of literature1 laws1 and religious policies that we are acquainted with indicate that the numerous ,babylonian and ,assyrian settlements in each great empire possessed social and political conditions similar to those of our days4 ,science and art were then sufficiently advanced to enable these ancient people to live as agreeable1 moral1 and legally secure lives as those of any subsequent peoples4 ,the ,chinese appear to have been making similar progress to that of the ,babylonians about the same period4 ,it would seem that both these peoples were in contact with a similar but earlier cultured race in central ,asia4 ,although the early ,chinese were a religious people1 they appear to have been more philosophical than the ,babylonians4 ,this enabled them to make further progress in the abstract sciences4 ,in subsequent years they made rapid strides in the physical sciences1 as will be shown later4 ,the ,egyptians came into prominence toward the end of the ,babylonian and ,assyrian empires1 and for many centuries played a great rle in developing civilization4 ,the numerous benefits which they bestowed upon the world by their researches in science and art are not fully appreciated4 ,early history pictures two great ,asiatic races struggling for supremacy in ,india4 ,they were the ,aryans1 a fair-skinned people1 and the ,dravidians1 a colored people4 ,the ,aryans succeeded in displacing the ,dravidians in the great plains1 upon which they settled and developed large cities1 important world commerce1 and contributed great art works and scientific and philosophical discoveries to the world's stores4 ,the ,dravidians retired to the hill country1 where their representatives still live4 ,the minds of the various ,indian peoples have always been strongly philosophical4 ,this led them to the development of numerous religious sects and philosophical systems1 and they made important mathematical discoveries4 ,while the scientific bent of the ancient ,greeks was of a concrete nature1 which tended toward geometrical proofs for scientific problems1 that of the ancient peoples of ,india was toward numerical symbolism and arithmetical proofs4 ,we find that when the ,greeks were developing geometry the ,indians were contributing to arithmetic and algebra4 ,the ,chinese closely resembled the ancient ,indians in the philosophical tendency of their minds2 but1 owing perhaps to the different conditions under which they lived1 they were more concrete in their ideas4 ,they also made progress in mathematics and developed medicine1 chemistry1 metallurgy1 and many of the sciences which were applied to commercial and industrial uses4 ,the progress made in mathematics in ,china was transmitted to ,egypt1 and therefore to ,europe1 through ,india4 ,among early ,chinese discoveries in mathematics were methods of solving numerical equations and the development of magic squares and circles1 which gave a great stimulus to studies in geometry and astronomy4 ,the ,arabs1 ,greeks1 and ,romans took up the discoveries of the ,asiatic peoples1 and the ,egyptians enlarged them and passed them forward to us4 ,the ,arabs solved cubic equations by geometrical means1 perfected the basic principles of trigonometry1 and made great advances in mathematics1 physics1 chemistry1 and astronomy4 ,a survey of the early history of science indicates that from the remotest period man was engaged in grappling with the great principle of causation4 ,progress was necessarily slow at first on account of the scarcity of tested data4 ,then it became more rapid4 ,soon after the founding of the great city of ,babylon we find that the ,babylonians were possessed of enough knowledge of the arts and sciences to enable them to become world traders and great industrial undertakers4 ,they built many cities and lived highly civilized lives4 ,the history of modern science may very properly be dated from the building of ,babylon4 ,,chapter ,,iii ,,pre-,,babylonian ,,science ,the transcending wonders of the phenomena of the heavenly bodies attracted the attention of primitive man at an early period of his intellectual development4 ,the succession of day and night1 the phases of the moon1 comets1 meteorites1 the eclipses of sun and moon1 the recurrence of the seasons were observed and recorded4 ,in this way1 through long uncivilized times1 many scientific facts were noticed and handed down by tradition1 and probably were among the first scientific data collected4 ,we have no means of determining when the primitive science of astronomy became systematized1 although there are reasons for believing that it was roughly outlined at a remote date4 ,there was a tradition among the ,babylonian priests that their astronomical observations and records went back to a period of more than #djj1jjj years4 ,this statement was believed by the people of antiquity1 and was made to ,alexander the ,great during his ,indian campaign4 ,astronomy appears to have been developed into an organized system by the primitive peoples of central ,asia4 ,it was carried to ,china1 ,india1 and ,arabia by learned travelers4 ,there were government astronomers in ,china before the year #cjjj ,b4 ,c41 and history records that two of these officials1 named ,ho and ,hi1 were beheaded in the year #baei ,b4 ,c4 for being careless in their work and failing to issue a timely prediction of a solar eclipse4 ,chinese history also relates that the ,emperor1 in #bheg ,b4 ,c41 issued an edict recommending the study of astronomy4 ,from these and other historical references we learn that nearly #e1jjj years ago astronomical science was not only well developed1 but that its educational value was recognized4 ,while attention was being given to the study of astronomy in ,china1 this science was independently developed in ,india4 ,the astronomers of ,india invented a different system from that of the ,chinese1 and compiled numerous astronomical tables which were published and widely used as far back as #cajb ,b4 ,c4 ,these early astronomical studies resulted in the division of time practically as we know it to-day4 ,the ,babylonians had a week of seven days4 ,the days bore names of the planets and were divided into hours and minutes4 ,days were combined into months and years4 ,the ,babylonian and ,chaldean astronomers1 like those of ,china and ,india1 were important men and were credited with great learning4 ,the ,babylonian month began on the evening when a new moon was first observed4 ,an adjustment was made necessary between the months1 owing to the fact that the actual lunar interval is about twenty-nine and a fraction days4 ,numerous astrological observations were made with the view of obtaining data to facilitate the monthly adjustments4 ,the taking of these observations was made easier by maps of the heavens which were recorded on baked clay tablets and prisms4 ,similar maps of the world1 with positions fixed by astronomical observations1 were likewise made in ,babylonian times4 ,the usefulness of astronomical observations and predictions led to the belief that they could be employed with advantage for wider purposes4 ,the astrologers endeavored to deduce omens and forecast horoscopes4 ,in order to facilitate their calculations1 the astrologers invented calculating and time-dividing machines4 ,tablets from the royal library at ,nineveh indicate that ,chaldean astrologers possessed mechanisms which divided the hours of the day by mechanical means4 ,these were forerunners of modern clocks and timepieces4 ,these early scientists represented the earth as a vast circular plain1 intersected by high mountain ranges and surrounded by a large river1 with other mountain chains which lost themselves in an infinite ocean4 ,the heavenly vault was believed to be supported by the highest peaks of the outlying mountains4 ,it was owing to the peculiar nature of this cosmogony that the pre-,babylonians and ,babylonians were unable to develop a satisfactory mechanical view of the world4 ,the world had to wait for an adequate mechanical theory before general knowledge could be advanced1 so that men like ,newton and ,laplace could correct the errors of early theories and furnish a sound working hypothesis4 ,the advancement of science requires methodical observations and the use of the highest powers of the imagination4 ,it is thinking in picture-like figures that supplies primitive reasoning4 ,while pure reasoning deals with abstract1 verbal images1 the more concrete picture-thinking deals with object-images4 ,the differences between thinkers and dreamers is chiefly in the way their minds act4 ,but even thinkers are supplied with thought material by the elementary mental operation of picture-thought1 dreams1 or dream-thinking4 ,science needs the active use of the imagination to anticipate experience and suggest the issues of a process in course of action4 ,most great inventions1 and probably all primitive inventions1 were stimulated by imagination4 ,but the imagination1 unless skillfully directed1 is liable to numerous errors4 ,that is why in all ages there has been much error in connection with knowledge4 ,there could1 however1 be little or no progress without imaginative work4 ,it is only within very recent years that the modern sciences have been stripped of much absurd matter derived from crude imaginative work4 ,when we bear this in mind1 we have the key to the part played by ancient myths1 magic1 and ceremonies in developing civilization4 ,the term magic is derived from the ,persian term for priest4 ,the magi1 or priests of ,zoroaster1 their religion1 learning1 and occult practices had important world-wide effects just before the ,babylonian era4 ,magic is a pioneer of religion1 philosophy1 and science4 ,medicine was benefited1 in some ways1 by the priests seeking means for dealing with the work of the spirits of evil4 ,chemistry and metallurgy were also advanced1 and new realms of knowledge were opened even by magicians4 ,the magic of the ,babylonians survived their empire4 ,it was handed over to the ,egyptians and contemporary peoples1 and was in turn passed down to the magicians and alchemists of the ,middle ,ages1 and to the dramatists1 poets1 and novelists of all ages4 ,the accumulation of scientific facts was greatly facilitated by the improvements made by the ,babylonians in the manufacture of earthenware tablets1 scrolls1 and prisms4 ,beautifully drawn cuneiform picture signs recorded on these all the knowledge of the day4 ,these stonelike records were filed away in many monasteries and libraries4 ,subsequently1 letters were invented1 alphabets were formed1 and writing displaced the hieroglyphic symbols4 ,the invention of alphabets made reading easier4 ,this resulted in giving an impetus to education which has had cumulative effects right down through the ages4 ,we are now in a position to realize why scientific discoveries were made very slowly1 and at long intervals apart1 in early times4 ,facts had to be accumulated1 studied1 grouped1 and compared4 ,accounts of these studies had to be pictured and stored away for future use4 ,only exceptionally learned men did this4 ,but when alphabets were invented and education increased1 numerous minds became active and there was a great extension of thought1 experimentation1 and philosophical contemplation4 ,this was followed by the establishment of new religious houses1 schools1 and philosophical academies1 at all of which the ablest men of the day emulated the scholars in formulating theories and making inventions4 ,soon after the perfecting of cuneiform writing in ,babylon1 characters were devised for representing numbers4 ,a vertical1 arrowlike wedge represented the figure #a1 while a horizontal wedge stood for #aj4 ,a vertical and horizontal wedge1 placed together1 signified #ajj4 ,other arrangements of these characters meant that they were to be multiplied1 subtracted1 divided1 or added together4 ,in this simple manner all kinds of arithmetical results could be recorded4 ,the ,babylonian mathematicians were familiar with decimals1 integers1 and fractions1 and their tables and records of astronomical and engineering calculations reveal a remarkably high degree of mathematical ability1 indicating that peoples who preceded us by several thousands of years were familiar with the more important calculations requisite in trade and industry as well as for astrological computations4 ,babylon was a great world metropolis4 ,it occupied a position similar to that occupied by ,london to-day4 ,its merchants were engaged in world-wide commercial operations which needed good systems of bookkeeping and accountancy4 ,these1 in turn1 presupposed a highly developed arithmetical system4 ,practically all the arithmetical calculations used in commerce to-day were employed by them4 ,their accountants1 like those of ,china to-day1 used the abacus1 or calculating machine4 ,a lucid illustration of the accuracy of ancient calculations1 the efficiency of their reports1 and the confidence with which they executed intellectual duties is afforded by the following translation of a ,babylonian astronomer's official report3 ,to the ,king1 my lord1 thy faithful servant1 ,mar-,istar4 444 ,on the first day1 as the new moon's day of the month of ,thammuz declined1 the moon again became visible over the planet ,mercury1 as ,i previously had predicted that it would to my master the ,king4 ,my calculations were accurate4 ,the records of ,babylon furnish us with a wealth of documents of this character4 ,the numerous peoples of ,india have always been divided into castes4 ,this has resulted in the pioneering work in science falling to the priests4 ,however1 the principal priests were among the most intellectual men of each generation and1 as they traveled in search of instruction1 ,india was always in contact with the progress made in ,china1 central ,asia1 and ,babylonia4 ,these great centers of ancient learning progressed together4 ,the ,indians were able mathematicians and discovered and developed at an early period what is now known as ,arabic notation4 ,in this work they were assisted by the ,babylonians4 ,the ,indians1 like the ,chinese and ,babylonians1 solved problems in interest1 discounts1 partnership1 the summation of arithmetical and geometrical series1 and determined number changes in combinations and permutations with ease4 ,they were also proficient in algebra1 the extraction of the roots of numbers1 various classes of equations1 and the principles of trigonometry4 ,the ,chinese have always been good mathematicians4 ,it is probably due to this fact that they have at all times been such able traders and bankers4 ,we are not so familiar with the works of ,chinese mathematicians in pre-,babylonian times as we are with the ,indian2 but the references of contemporary writers indicate that the ,chinese scientists were as able and active as their contemporaries4 ,we have remarked the high degree of perfection which was attained in the ,babylonian era by scholars in science and mathematics4 ,similar perfection was attained in art1 industry1 law1 and medicine4 ,the wonderful law work that has come down to us under the name of the code of ,hammurabi indicates not only the extensive progress which had been made in law1 but incidentally through its references the progress of agriculture1 industry1 commerce1 and business4 ,many references in the ,hammurabic code1 written about #bcjj ,b4 ,c41 show that the medical profession had attained considerable advance in ,babylon4 ,surgeons were daring operators4 ,they commonly performed operations for cataract4 ,many of the common major operations now performed by surgeons were also done by the ancients4 ,they were experts at setting fractured bones4 ,the physicians made effective use of drugs4 ,many drugs employed to-day were known to them4 ,the discoveries of the early oriental nations were collected and developed in ,babylon4 ,the entire fields of science1 mathematics1 geometry1 agriculture1 astronomy1 philosophy1 and art were focused in ,babylon and handed down to the ,egyptians and the ,greeks4 ,much credit that is given to ancient ,greece should be shared also by ,babylon4 ,it was from ,babylon that ,greece obtained the principles of its civilization1 arts and sciences4 ,even ,greek architecture and sculpture were originally derived from ,babylon4 ,,chapter ,,iv ,,egyptian ,,science ,the early civilization in ,egypt developed in the ancient cities of ,thebes and ,memphis4 ,authorities on the dawn of history in ,egypt are unable to definitely account for the origins of the various peoples who have ruled the land4 ,one school contends that the early negroid inhabitants originated in ,africa4 ,another school opposes this view and suggests an ,asiatic origin4 ,each of these schools can marshal facts to sustain its contentions4 ,the truth is that ,africa was inhabited at such an early period that we are unable to fully trace back the movements of its races4 ,man was divided into species and subspecies at a very remote period4 ,the dominant peoples in each country1 in each era1 were the successful contestants in long conflicts for supremacy4 ,many races have vanished without leaving any traces beyond reversional strains which still come to the surface at times in families living to-day4 ,the laws of evolution1 only recently deciphered1 are the sole means we possess for learning about many of the long-perished species of men4 ,a few races1 too weak to ever gain supremacy and themselves to occupy districts1 or countries1 have survived by dwelling among stronger races4 ,the ,ainus1 in ,japan1 and the ,jews in ,asia and ,europe1 are well-known examples4 ,illustration3 ,,model ,,of ,,an ,,early ,,electric ,,motor ,the original was invented by ,m4 ,h4 ,jacobi in #ahcd and was used in #ahch to

,,whitney',s ,,cotton ,,gin ,this device1 invented in #agic1 revolutionized the cotton and cotton manufacturing industries4 ,egypt1 owing to its remarkable geographical situation between ,asia1 ,europe1 and the vast continent of ,africa1 has been a great highway for race migrations4 ,many peoples have lived and ruled there and passed on before incoming tides of new and more vigorous peoples4 ,each race1 undoubtedly1 during its residence in ,egypt contributed to the general fund of ,egyptian knowledge and customs and assisted in the development of science4 ,the tombs of ,thebes have given us bodies of ancient ,egyptians of more than six thousand years ago4 ,at that time the people were characterized by the ,grecian type of profile4 ,they resembled the contemporary active peoples in ,india and ,arabia and did not differ much from the ,egyptians of our day4 ,the incoming streams of people who settled in the ,nile valley1 both ,asiatic and negroid1 changed the appearance of the ,egyptians at different times by intermarriage1 but when their vigor waned and they were crowded out by other peoples1 the ,egyptians assumed their regular ,semitic characteristics4 ,egyptian history really begins with the old kingdom dynasties1 about ten thousand years ago4 ,the tombs of ,abydos have furnished material for accounts of this early period4 ,there were eight powerful kings in the first dynasty and all of them contributed to the advancement of civilization4 ,abydos1 and later ,memphis1 were their principal cities4 ,they ruled in great luxury and were patrons of the arts and sciences4 ,the art works1 sculptures1 and carvings in ivory and ebony of this era speak in eloquent terms of the taste and high mental powers of the people4 ,modern museums are well supplied with relics of those times1 which illustrate the degree of civilization attained by the ,egyptians at the beginning of their history better than any written account4 ,the early ,egyptians adopted the sciences1 arts and customs of the ,babylonians4 ,with these as a basis the priests and learned men experimented and made many independent researches and discoveries4 ,the pyramids1 erected near ,cairo #cjjj ,b4 ,c41 indicate the high degree of culture which the early ,egyptians had attained4 ,these renowned monuments to the kings were scientifically designed and constructed to exist for all time4 ,in order to contribute to their usefulness1 they were planned so as to exhibit correct geometrical forms and indicate the cardinal points of the compass and the positions of certain astronomical bodies4 ,the details of their construction disclosed much mathematical1 geometrical and physical knowledge1 and their actual building called for not only an all-around mechanical skill but a high degree of engineering ability4 ,they were constructed of various materials4 ,some large granite blocks were used in the outside walls and these were brought from the upper ,nile4 ,they were towed down the river on barges and were lifted into the positions in which they are found to-day4 ,various mortars and mortar mixtures were employed in binding the brickwork and masonry4 ,these called for a good knowledge of chemistry and physics4 ,the arches and sloping walls of some of the larger pyramids show how well the architects and engineers of the day knew their professions4 ,with similar means in their possession1 the best professional men of the present day would find it difficult to get such splendid results4 ,in the past few years1 lapidaries and gem-workers have learned to cut stones and gems with steel disk-wheels1 the cutting edges of which are furnished with carborundum or emery powder or insets of diamonds4 ,the pyramid builders knew this method of sawing and cutting stones4 ,they actually employed bronze saws set with diamonds to cut the huge blocks of granite1 syenite1 diorite1 and basalt used in the construction of the pyramids4 ,they also set the cutting ends of their rock drills with diamonds1 and bored rocks as we do to-day with diamond core drills4 ,the art of making these tools was afterward lost4 ,only within the past half-century have mechanical rock saws and diamond drills been reinvented4 ,this brilliantly indicates the inventive ability of the engineers at the dawn of ,egypt's history4 ,the builders of the splendid monument of ,rameses ,,ii in the ,memnonium1 at ,thebes1 which weighs #hhg long tons1 transported the huge stone by land from the quarries at ,e',sooan1 a distance of #ach miles4 ,such tasks appear never to have deterred early ,egyptian engineers and architects4 ,they were so sure of their ability to carry their great operations to satisfactory completion that they never hesitated in agreeing to the severest penalties for nonfulfillment of contract4 ,their cranes1 levers1 wedges1 rock drills1 pumps1 air blowers and compressors1 and building tools all showed how well mastered was their knowledge4 ,their quarrying methods were similar to those used in the best practice to-day4 ,when huge blocks and slabs of stone were needed the required dimensions were marked on the rock and channeled out4 ,metal wedges were forced into the channels and struck at once by a large number of hammers4 ,the constant vibration1 in time1 broke off the stone with clean-cut surfaces4 ,when these were to be carved into statuary or ornamental shapes it was often done at the quarries1 so as to reduce transportation difficulties4 ,water transportation was used when possible4 ,when the stone had to be moved over the desert sands it was lifted by cranes and set on sleds drawn by men or animals1 or driven forward by levers1 just as heavy steel machinery is moved by modern engineers4 ,the principle of the siphon was known to the ,egyptians at an early period4 ,it was employed daily in many homes for supplying water and for drawing off wine from barrels and tanks into domestic utensils4 ,its principal use1 however1 was in civil engineering works4 ,siphons were constructed on a large scale for furnishing water to villages1 draining land for farming1 and for irrigation purposes4 ,they were built1 in many known instances1 for carrying large quantities of water1 in high lifts1 over hills4 ,herodotus tells us that the science of geometry was discovered by the ,egyptians as a result of the necessity for making annual surveys of the farming lands in the ,nile valley4 ,when geometry was established as a practical science1 land and astronomical surveying were simplified and many branches of mathematics were enlarged4 ,the science of marine surveying was also developed and this led to a great improvement in map-making and in geography1 in which the ,egyptians became famous4 ,the skill attained by the ,egyptians in land surveying required accurate surveying instruments4 ,these were invented at an early period4 ,the ,greeks claim the invention of the theodolite and similar instruments1 but ,egyptian history shows that gnomons1 surveying compasses1 and levels were used by ,egyptian surveyors long before the ,greeks began to study the learning of ,egypt4 ,astronomical science made great progress in ,egypt4 ,the theory attributing to the sun the central place in our planetary system1 now called the ,copernican theory1 was known and used in ,egypt4 ,they were familiar with the obliquity of the ecliptic1 and knew that the ,milky ,way was an aggregation of numerous stars of various sizes4 ,they understood that moonlight is simply the reflected light of the sun4 ,the movements of comets1 the positions of the principal stars and stellar constellations and other astronomical phenomena were studied and charted on astronomical maps or recorded and forecasted in astronomical tables4 ,the discoveries made by the ,greek scientists naturally stimulated philosophical thought1 which in turn reacted upon scientific experimentation and led to a broadening of the scope of general research work4 ,we are dependent upon the pictorial records of early ,egyptian times for descriptions of the instruments and machinery employed and these are not always clear4 ,they indicate1 however1 that the ,egyptians quickly learned the sciences developed by the ,babylonians and other ,oriental peoples and improved them4 ,their knowledge of astronomy1 mathematics1 geometry1 chemistry1 physics1 medicine1 and agriculture was extensive4 ,the priests and learned men taught the pure sciences and constantly experimented2 the engineers1 architects1 surveyors1 and mechanics applied the sciences to the arts4 ,in one of the records of an early dynasty the father of a student sailing up the ,nile to begin his studies in one of the leading scientific schools gave this advice3 ,put thy heart into learning and love knowledge like a mother1 for there is nothing that is so precious as learning4 ,the ,mesopotamian peoples1 as we saw in the last chapter1 considered the stars and principal heavenly bodies as deities4 ,the ,egyptians did not do this1 although they looked upon the heavens as the abode of all pious souls4 ,their astronomical knowledge at the time of the establishment of the ,new ,empire at ,thebes1 about the year #acbj ,b4 ,c41 was remarkably extensive4 ,the ,egyptians divided time in accordance with the course of the sun into periods of #cfe days1 and these were divided in accordance with the course of the moon into periods of about #bi days4 ,thus the basis of the system of years and months used by us was perfectly understood by the ,egyptians4 ,the science of medicine was developed at a very early period in ,egyptian history4 ,the various divisions of physicians1 surgeons1 pharmaceutists1 veterinarians1 and dentists organized by the ,babylonians were retained by the ,egyptians4 ,many names of distinguished practitioners have been handed down4 ,nevertheless1 their anatomical knowledge remained poor1 and there were many superstitious practices connected with medicine4 ,the various medical manuals which have been preserved show that the ,egyptian physicians studied diagnosis with modern thoroughness4 ,they were aware that an exact knowledge of each disease1 obtainable only by a complete study of the symptoms1 was necessary before a correct treatment could be prescribed4 ,when the magic and the superstitious dressings are abstracted from ,egyptian medical works and prescriptions1 we find that the broad principles were sound and efficient4 ,they were developed along lines similar to those of modern times4 ,mathematics attracted much attention in ,egypt4 ,the learning of ,oriental countries on this subject was readily absorbed by the ,egyptians4 ,the ,greek historians were so surprised at the efficiency of the ,egyptians in this branch of knowledge that they almost unanimously asserted that the mathematical sciences originated in ,egypt4 ,the pyramid base lines run in the direction of the four points of the compass1 and were determined by correct astronomical methods4 ,the astronomers and surveyors were skilled in trigonometry4 ,fractions were known to the ,egyptians1 who were taught in the schools of ,babylon4 ,the modern x1 representing an unknown factor1 was known to the ,egyptians under the name of hau4 ,quadratic equations were employed by them4 ,the problem of finding x and y1 when x y #ajj and x3y #a31 one of the earliest problems of this character known1 was found in a papyrus at ,kahun4 ,the problem was stated as follows3 ,a given surface of1 say1 #ajj units of area1 shall be represented as the sum of two squares1 whose sides are to each other as #a34 ,the papyrus gave the working out of the solution4 ,many similar problems are given in mathematical works and papyri4 ,they show the proficiency in mathematics that ,egyptian scientists had attained at a remote period4 ,but their methods of expressing mathematical problems were crude and1 consequently1 involved much tedious labor in finding solutions4 ,there can be little doubt that if effective mathematical symbols had been devised the abstract sciences would have made even greater progress than they did in early ,egypt4 ,when we study the complicated solutions of algebraic problems made by the ,egyptians1 owing to the lack of simple symbols1 we can appreciate how greatly modern mathematical science is benefited by the devices now employed for expressing quantities1 variations1 and operations4 ,the ,egyptians were expert in applying the discoveries of science to the arts4 ,the ,nile made their country potentially rich in agriculture1 and they devoted much attention to inventing such things as single and double plows1 rakes1 and other agricultural machines1 many of which were drawn by oxen1 donkeys1 and other animals4 ,reaping was done with sickles and scythes4 ,not only was irrigation understood and widely practiced1 but the importance of fertilization was recognized4 ,the farmers understood the preservation of meat1 vegetables1 and foodstuffs generally1 by drying or pickling4 ,they also brewed beer and made wines1 vegetable and seed oils1 and alcohol4 ,the selection of breeding animals and the principles of variation were understood and employed for developing particular breeds of cattle and farm stocks4 ,the papyrus reed grew luxuriantly in ,egypt and this resulted in the discovery of paper making1 weaving1 thread making and many textile methods4 ,these industries led to the invention of looms1 rope and twine twisting appliances1 flax weaving and other machinery4 ,the linens and cloths made by these machines have never been excelled4 ,dyeing was developed with the textile industries4 ,as the skies of ,egypt are bright1 the people in all ages have had a fondness for brilliant colors4 ,the call for bright textile colors led to a considerable development in the chemistry of dyes and dyeing4 ,vegetable and mineral dyes were used4 ,dyes were not always applied to the whole pieces of goods1 but stenciling and other methods of patterning were used4 ,the highly organized artistic skill of the people demanded art-designed textiles and the manufacturers responded with beautiful and rich materials4 ,the fur and feather industries became important at an early period4 ,the ,egyptians were fond of beautiful ornamental skins like those of the panther or gazelle4 ,such skins were manufactured into numerous domestic articles1 made into clothing or used as rugs1 mats1 and seat coverings4 ,skins not valuable for art purposes were sent to the tanners to be converted into various kinds of leather4 ,tanning was highly developed1 and the tanners turned out leathers which are to-day admired for their excellence4 ,the tanners carried on their industries by chemical processes similar to those in use to-day4 ,the scarcity of wood in ,egypt led to the invention of various substitutes4 ,one common substitute was a kind of papier mch4 ,this was manufactured out of linen1 wood or vegetable pulp and various kinds of paste4 ,when it was used for art work the molded forms were covered with lacquer or various kinds of stucco4 ,very beautiful objects were manufactured from these substances1 which indicate that the artists possessed a wide practical knowledge of physical and chemical principles4 ,chemical knowledge was also well shown in their manufacture of glass4 ,they excelled in this industry4 ,all kinds of glass were made and decorated by staining and glazing4 ,the glassmakers were able to imitate precious stones in glass and their glass-bead and enamel work has never been excelled4 ,some modern chemists express the opinion that glass making was carried to a greater degree of perfection in ,egypt than any modern nation has attained4 ,egyptian porcelains were also finely executed4 ,these were enameled1 stained1 and decorated in numerous ways4 ,the colors1 glazes1 and art mediums employed by the artists in pottery and porcelain necessitated a wide chemical knowledge4 ,some of the pigments employed both in glass and porcelain ornamentation were made from metals4 ,their use required a knowledge of metallurgy4 ,metals like lead1 nickel1 manganese required fluxing and refining before they could be secured in a state sufficiently pure to be used as bases for colors4 ,not only did the artists know the value of many metallic oxides1 but they understood how to secure the tints resulting from blending different oxides1 and by acting upon metals with acids1 just as they acted upon vegetable and metallic dyes with acids to get rare tones in linen dyeing4 ,mordants were employed in dyeing cloths and these were acted upon by acids and alkalies to produce various colors4 ,we are dependent upon the relics which have been preserved for our knowledge of the chemical and physical learning of the ,egyptians4 ,no chemical books of theirs have come down to us1 and inferences must be drawn from the results seen4 ,in carrying out metallurgical operations1 the ,egyptians employed small blast furnaces and melting pots4 ,air was compressed by bellows and conducted into molten substances by pipes4 ,the methods of metal working1 melting1 rolling1 forging1 soldering1 annealing1 and chasing were similar to common methods in use in modern times4 ,the ,egyptians were a practical people4 ,they made wonderful progress in the industrial arts and learned enough of scientific principles to enable them to deal with much success with the mechanical1 agricultural1 astronomical1 medicinal1 and chemical problems encountered4 ,but1 like the ,babylonians1 ,assyrians and other ,oriental peoples1 the ,egyptians did not systematize their sciences4 ,their investigations were always carried out with practical objects in view1 and when the objects were attained the experiments ceased4 ,they never discovered a true scientific method4 ,that was left to be done by another people who were long students of ,egyptian science and who1 taking all the learning of ,egypt1 worked out from it1 as a basis1 the principal sciences as we have them to-day4 ,the ,greeks took the torch of scientific progress from the ,egyptians1 organized learning1 and passed it on to the ,romans and other peoples in sound1 effective and augmented forms4 ,the ,greeks idealized and systematized scientific principles1 whereas the ,egyptians and earlier peoples rested content with the results they could obtain by their practical efforts4 ,we will find that1 throughout the history of science1 progress has always been made by similar reactions between peoples possessing the one a practical1 the other a philosophical genius4 ,,chapter ,v ,,founding ,,of ,,systematic ,,science ,,in ,,greece ,the world is indebted to the ,greeks as much for science as for art and literature4 ,the idealistic spirit of ancient ,greece invested scientists as well as poets1 artists1 and thinkers generally4 ,but the ,greek scientists were students in the great schools of ,egypt and brought much of their knowledge from that country4 ,the greatest contributions made by ,greece were in the nature of methods and analysis4 ,they were led to these by the tendencies of the ,greek mind to abstract thought and philosophical investigations4 ,they soon recognized that science is knowledge gained by certain methods of abstraction4 ,data had to be systematically collected1 digested1 classified1 and impartially studied4 ,the results of such studies had to be assembled and expressed in the most useful forms4 ,progress had to be made by the trial and error method and the results of experiments tested by synthesis as well as analysis2 by induction as well as deduction4 ,the ,ionian philosophers were the first to break away from the mythological traditions surrounding the principles of ,egyptian and ,asiatic science4 ,thales of ,miletus about the year #ehj ,b4 ,c4 taught that there is an essence1 force1 or soul in all things4 ,this universal principle of activity is superhuman4 ,seeking to find of what the world is made1 he arrived at the idea that water1 or moisture1 is the basic element4 ,all matter1 he said1 is water in various forms and combinations4 ,here we see scientific knowledge sought with a definite aim and with unity of purpose4 ,none of the earlier peoples had ever attempted to approach knowledge in this logical and fruitful manner4 ,when the learned ,babylonians were asked what the earth was they simply said3 ,when the world was created1 ,marduk1 the sun god1 took ,tiamat1 or ,chaos1 and divided her4 ,the sky was formed above and the earth below4 ,and the ,egyptians answered the question in a similar way by saying3 ,when the world was created1 ,shu tore the goddess ,nuit from the arms of ,keb1 and now she hangs above him and he is the earth4 ,it was this kind of statement that ,thales cast aside4 ,he sought for more concrete definitions4 ,customary beliefs were not acceptable to him2 his knowledge must be based on reason4 ,here we see the dawn of a new scientific spirit and the beginning of a new method of investigating knowledge4 ,the world was introduced to a new field of intellectual activities4 ,the theory of ,thales was studied by other ,greek philosophers4 ,but ,anaximander1 a friend of ,thales1 rejected it1 and in its place suggested that there is one eternal1 indestructible substance which constitutes the basis of matter4 ,this was not water but an infinite eternal motion4 ,water is subjected to extremes of temperature4 ,under such conditions nothing could have been stable enough to constitute matter4 ,a primary substance must be free from warring or antagonistic elements4 ,the world arose1 said ,anaximander1 through the evolution of a substance subjected to temperature changes which developed from the eternal1 boundless1 basic element4 ,a sphere of flame arose from this1 as from an explosion1 and assumed a rounded form with concentric divisions4 ,as these rings became detached1 the sun1 moon1 stars1 and other heavenly bodies and the earth were formed4 ,aristotle tells us that1 according to ,anaximander's theory1 the terrestrial region was at first moist2 and1 as the moisture was dried up by the sun1 the portion that was evaporated produced the winds and the turnings of the sun and moon1 the remaining portion becoming the sea4 ,in time the sea1 ,anaximander held1 would dry up4 ,the heat1 or fire1 of the world would burn the whole of the cold moist element4 ,then the world would become a mixture of heat and cold like the boundless1 primary element surrounding it1 and by which it would be absorbed4 ,this theory of matter and the evolution of the world marks a notable advance over any previous scientific theory4 ,it was well developed by numerous teachers of the ,milesian philosophical school and has played a great rle in intellectual history4 ,the daring nature of some of ,anaximander's explanations of earthly organisms may be realized from a sketch of his views on the evolution of animals4 ,he taught that living creatures arose from the moist element as it was evaporated by the sun4 ,man at first resembled a fish4 ,all animals were developed in the moisture wrapped in a protecting cover or bark4 ,as they advanced in age1 they came out into a drier atmosphere and discarded their protective coats4 ,man was not an original creation1 but resulted from the fusion of other species4 ,anaximander's reason for this statement was that the period of infancy of the human being is so long that had he been born that way originally he could not have survived4 ,there must have been a slow development from ancient ancestors4 ,this may be regarded as an anticipation of the ,darwinian theory4 ,thus man's thoughts in succeeding ages have a rhythmic swing4 ,anaximenes rejected some of ,anaximander's ideas and furnished new ones to take their places4 ,he was not so daring a thinker as his predecessor1 and his theory of the world was not as interesting as ,anaximander's4 ,many of his teachings1 however1 are accepted as sound to-day4 ,anaximenes contended that the basic element was not boundless1 but determinate4 ,innumerable substances are derivable from it and1 just as our soul1 like an atmosphere1 holds us together1 so do breath and air encompass the whole world4 ,air is always in motion1 otherwise so many changes could not be made by it4 ,it differs in various substances in virtue of its rarefaction and condensation4 ,the perpetual changes taking place in the world owing to the instability of matter were emphasized by ,heraclitus4 ,he taught that there is nothing immutable in the world process excepting the law or principle which governs it4 ,cosmological speculations were not the only ones attracting the attention of the ,greek scientists4 ,pythagoras1 for example1 founded a philosophical college devoted to mathematical studies which resulted in the development of arithmetic to points beyond the requirements of commerce4 ,he made arithmetic the basis of a profound philosophical system4 ,pythagoras studied science in ,egypt and first became familiar with ,egyptian and ,babylonian mathematics and geometry4 ,he also studied the ,milesian cosmological philosophy4 ,on his return to ,greece from his foreign studies he sought to discover a principle of homogeneity in the universe more acceptable than any suggested by the earlier philosophers4 ,he had noticed numerous relationships between numbers and natural phenomena1 and believed that the true basis of philosophy was to be found in numbers4 ,in seeking data to sustain this thesis1 he discovered harmonic progression4 ,his experiments showed that when harp strings of equal length were stretched by weights having the proportion of 331 they produced harmonic intervals of an octave1 a fifth and a fourth apart4 ,since he saw that harmony of sounds depended upon proportion he concluded that order and beauty in the world originate in numbers4 ,there are seven intervals in a musical scale1 and seven planets sweeping the heavens4 ,seven must1 therefore1 be a basic number4 ,this suggested to him his ideas regarding the harmony of the spheres4 ,pythagoras and his students found that the sum of a series of odd numbers from #a to #bn#a was always a complete square4 ,when even numbers are added to the above series we get #b1 #f1 #ab1 #bj1 etc41 in which every member can be broken into two factors differing from each other by unity4 ,thus #f #b4c1 #ab #c4d1 #bj #d4e1 etc4 ,such numbers were called heteromecic4 ,numbers like n7n#a7 were called triangular4 ,a large number of other arithmetical relations were found and given distinctive names4 ,the ,pythagoreans were also familiar with the principles of arithmetical1 geometrical1 harmonic1 and musical proportion4 ,illustration3 ,,de ,,witt ,,clinton ,,train ,,of #ahca ,,beside ,a ,,modern ,,locomotive ,illustration3 ,,locomotive ,,of ,,the #ahgj ,,period ,,still ,,in ,,use ,,in ,,the ,,ozarks ,illustration3 ,,john ,,bull1 ,a ,,locomotive ,,brought ,,from ,,england ,,and ,,put ,,into ,,service ,,in ,,america ,,in #ahca ,pythagoras made similar advances in geometry4 ,he believed that each arithmetical fact had an analogue in geometry1 and each geometrical fact a counterpart in arithmetic4 ,he devised a rule by which integral numbers could be found so that the sum of the squares of two of them equaled the square of the third4 ,he also developed the theory of irrational quantities4 ,the first incommensurable ratio discovered is said to have been that of the side of a square to its diagonal which is #a3b4 ,euclid 7#cjj ,b4 ,c47 developed this theory in the tenth book of his geometry as still used4 ,pythagoras not only placed mathematics on a solid scientific basis1 he also established the fact that the physical phenomena of the world are governed by mathematical laws4 ,little progress appears to have been made in astronomy by the ,greeks in the time of ,pythagoras4 ,the ,milesians and the associates of ,pythagoras advanced numerous theories1 but none of these was better than some of the ,egyptian ideas4 ,hicetas1 and others of this period1 believed that the sun1 moon1 stars1 and all other bodies in the heavens were stationary and that only the earth moved4 ,the great turning movement of the earth around its axis produced the illusion that it was the heavenly bodies which were moving while the earth remained stationary4 ,the astronomical theories of ,pythagoras1 ,hicetas1 and ,philolaus1 all affirmed that the universe is composed of the elements earth1 air1 fire1 and water1 the whole mass being of spherical shape with the earth at the center and all having life or motion4 ,these early theories1 #b1jjj years later1 did service by aiding to secure acceptance for the ,copernican theory4 ,the ,pythagorean ideas that the universe is one grand harmonious system1 and that thought instead of sense is the sole criterion of truth1 have exercised important influence on intellectual speculation throughout the ages4 ,in order to collect data for testing their theories in the physical and mathematical sciences1 the ,greeks invented many physical appliances4 ,the monochord1 employed in determining the relationships of vibrating harmonic strings is one of the first mechanisms used in practical physics that we have definite information about4 ,an anvil1 metal and glass disks1 and bell-shaped cylinders were employed in studying the movements of sound waves4 ,alcmon 7#ejh ,b4 ,c47 was one of the earliest of the ,greek anatomists4 ,he was a disciple of ,pythagoras and employed the logical research methods of his teacher in the investigation of medical problems4 ,although the ,egyptians had developed medical science to a considerable extent and had taught the ,greeks1 their methods were not based upon sound principles4 ,the result was that the more analytically minded ,greeks could not accept certain ,egyptian ideas4 ,the ,egyptian anatomical teachings were particularly crude1 and ,alcmon began to investigate that science4 ,his discoveries1 both in anatomy and physiology1 were very great4 ,he outlined the functions of the principal organs of the body1 discovered the optic nerve1 the difference between the arterial and nervous systems1 the ,eustachian tube1 the two divisions of the brain1 the nerves connecting the brain with the organs of sense and with the spinal column4 ,these advances placed the medical sciences on a logical basis similar to that of the physical1 mathematical1 and astronomical sciences4 ,this first great anatomist and physiologist invented the practice of anatomical dissection and surgical exploration1 and advanced the practice of medicine to a higher degree of usefulness4 ,after the ,greeks had satisfied themselves that they possessed a cosmological theory which answered the demands of reason they turned their investigations to the question of how matter was changed into its innumerable forms4 ,empedocles had taught that when the primary elements1 earth1 air1 fire1 and water1 were mixed in variable proportions they yielded different kinds of matter4 ,leucippus1 ,democritus1 ,anaxagoras1 and others studied the subject more carefully and developed a novel theory4 ,when matter is divided as far as possible do the ratios of the constituents remain the same8 ,this problem attracted their attention4 ,they also asked themselves whether there was not a simpler conception to explain the basic state of matter4 ,when they began their inquiries1 the qualities of matter were believed to reflect their essences4 ,for example1 the sweetness of honey and the color of the sky were real things which should be studied in themselves apart from honey and the sky4 ,democritus thought1 however1 that such changes of color as the sky undergoes at dawn and sunset would not take place if the colors were real elementary things4 ,while meditating on this the thought arose in their mind3 ,if we assume matter to be composed of an infinite number of minutest particles or atoms1 could we not explain the changes in matter by changes in atomic quantities and orders8 ,this line of thought resulted in the development of the atomic theory and the origin of the philosophic school of the atomists4 ,according to ,leucippus some of the atoms darting about in the universe collide and thus give rise to new substances4 ,he also believed that the atoms followed whirling or circular paths and that such rotary motions drew in neighboring atoms1 and that as these movements continued indefinitely within the atoms the constituents were being constantly rearranged1 the lighter elements being grouped around the periphery2 the heavier ones around the center4 ,these changes were due to pressure and impact4 ,these conceptions about atoms were carried into cosmological discussions and it was taught that there are various worlds and planets within the boundless universe1 each one moving freely according to physical laws1 unless fractured by collision with another4 ,zeno challenged these doctrines because of the importance attached to the whirling motion4 ,he attempted to show that such atomic motions are impossible4 ,his proofs of the impossibility of atomic motion were designed with the object of sustaining his own theory of an ultimate principle of unity4 ,his mental trend was toward negation4 ,whenever his rival ,parmenides argued affirmatively regarding a scientific principle1 ,zeno would invariably maintain the negative side of the question4 ,zeno's first proof of the impossibility of motion referred to the impossibility of passing through a fixed space4 ,he showed that by dividing a line into an infinite number of parts an infinite number of points would be obtained and these permitted no beginning of motion4 ,his second proof tried to show the impossibility of passing through space having movable boundaries4 ,the story of ,achilles and the tortoise illustrates this4 ,a pursuer in a race at every interval must reach a point from which the pursued starts simultaneously4 ,but the latter is always in advance4 ,the third1 or resting arrow1 argument showed that a moving arrow is at every instant in some one point of its track4 ,its movement at such instant is then equal to zero4 ,its track is a group of zeros4 ,no magnitude could be framed from these4 ,zeno also anticipated much later philosophical discussions1 like ,einstein's1 relating to the relativity of motion4 ,he took for an example a moving wagon4 ,its movement would appear different to observers on other moving bodies going in various directions4 ,they would see changes in rates of speed as well as in direction4 ,protagoras1 at a subsequent date1 developed this idea of relativity and showed that things are as they appear to each individual at the moment they are perceived4 ,he summarized his teaching in the aphorism3 ,man is the measure of all things4 ,the ,skeptics1 #bjj years later1 developed the ,protagorean theory of relativity1 and by a series of arguments attempted to prove that perceptions change not only with the different species of animate beings1 but with many conditions and circumstances4 ,it was also shown that not only man's perceptions are subject to changes1 but also his opinions following from his perceptions4 ,another school taught that to every opinion the opposite can be opposed with equally good reasons4 ,,chapter ,,vi ,,golden ,,age ,,of ,,greek ,,sciences ,science had made a great advance as a result of the researches and theories of the atomists4 ,a consistent mechanical theory of matter and the universe had been set forth4 ,science and philosophy were stripped of many of the old superstitions that had clung to them4 ,the leading theories invented were based on logical principles4 ,while these changes were being worked out1 numerous inventions of scientific instruments and apparatus were made and systematic methods of studying science were organized4 ,these furnished the means for still greater progress4 ,the apparent completeness of the mechanical theory of the universe satisfied the inquiring intellect4 ,the excitement caused by the scientific discussions and discoveries from the time of ,heraclitus subsided4 ,but after a short intervening period1 when public attention had been largely centered on practical affairs1 there was a reaction against science4 ,when scientific principles were quoted a tendency was shown to question their validity and usefulness4 ,this resulted in inquiries into the sources of knowledge and conduct and ushered in a new intellectual era that is now known as the ,humanistic period which1 beginning about #dej ,b4 ,c41 extended to #djj ,b4 ,c4 ,the ,sophists1 who were teachers of rhetoric and were accustomed to studying the phrasing of verbal statements1 became active in searching for the foundations of thought4 ,the ,protagorean theory of knowledge was based on ,empedocles's doctrine that the inner atoms advance to meet the outer ones4 ,perception is the resultant product of these atoms when they collide4 ,they believed that this perception is something else than the perceiving subject and is also something different from the object giving birth to the perception4 ,it is conditioned by both1 but has a distinct existence4 ,the doctrine of the subjectivity of sense perception was developed in explanation of this psychological problem4 ,from this it followed that knowledge must be strictly personal and could be true only under conditions existing at the instant of perception4 ,these limitations caused ,protagoras to advance his theory of relativity1 which teaches that man is the measure of all things4 ,facts are what appear to each individual to be statements of truth4 ,isocrates1 ,plato1 ,aristotle1 and ,socrates were the leaders of this intellectual movement4 ,socrates developed the ,pythagorean theory of intelligible forms4 ,the specific qualities of the senses belong to the realm of perception4 ,when these are withdrawn from an object of thought there remains only the form or idea4 ,therefore it is evident that pure1 intelligible forms constitute the essences of things4 ,the early scientists1 such as ,democritus1 thought1 perhaps1 in terms of atom forms4 ,socrates1 ,plato1 and later teachers looked upon forms as conceptions of similar logical elements4 ,knowledge1 in the view of ,democritus1 was essentially rationalistic4 ,plato considered knowledge as having ethical and sthetic purposes within itself4 ,each of these types of rationalism stimulated ,greek thought and resulted in a strong impulse to philosophical and scientific investigation4 ,they prepared the outlook for ,aristotle4 ,science had been hampered by the confusion raised by the discussions relating to forms4 ,aristotle realized that proper progress in logic1 physics1 and ethics1 the leading sciences of his time1 could not be made unless the essential nature of science were kept in view4 ,he saw that knowledge of the forms of correct thinking can be understood only by keeping in view the object of thought and this requires definite ideas of the general relations of knowledge and its objects4 ,the study of general relationships led to the study of particular or special relations4 ,the connection of general with particular ideas was unfolded1 and ,aristotle saw that conceiving1 understanding1 and proving result from the deduction of particular from universal1 or general1 ideas4 ,therefore science consists in deriving or deducing facts acquired through perception from their general grounds or phenomena4 ,the logical form of the syllogism naturally suggested itself to ,aristotle when engaged with these thoughts and the invention of the syllogism was one of the most brilliant contributions to knowledge made by the ,greeks4 ,the logical results of the invention of syllogistic forms suggested a solution of the problem of true reality which ,aristotle showed was the essence that unfolds in phenomena themselves4 ,this led to fruitful scientific results4 ,plato and his contemporaries unified mathematics1 formulated the definitions logically1 and demonstrated correct methods of criticism and proof4 ,a point was shown to be the boundary of a line2 while a line is the boundary of a surface1 and a surface the boundary of a solid4 ,this concrete definition of scientific elements progressed through the use of analytic methods1 by proceeding from the known to the unknown1 and led to the discovery of tests for scientific assumptions and of synthetic proof4 ,none of the earlier philosophers possessed anything like the progressive tools ,aristotle placed in the hands of scientists4 ,their use quickly led to a general review of knowledge and a great increase in the number of sciences4 ,the textbook on geometry compiled by ,euclid1 still used in many schools1 gives us a good picture of the state of scientific methods in his time4 ,euclid1 like ,aristotle1 ,plato1 ,socrates and others1 was a great systematizer4 ,he collected the geometrical proofs of his mathematical predecessors1 selected those which were logically correct and simple1 and raised on a few axioms1 or first principles1 a great geometrical system4 ,archimedes published textbooks on spherical and cylindrical geometry4 ,he proved that the surface of a sphere is equal to four times a great circle4 ,he showed the properties of spherical segments and methods for calculating surface areas and other parts of spherical forms4 ,this great scientist also developed mechanics and physics4 ,he investigated the lever and demonstrated the principle upon which its power is based4 ,he then studied hydrostatics and hydraulics1 and discovered the theory of specific gravity and invented methods for determining it4 ,apollonius began publishing scientific textbooks about forty years after ,archimedes4 ,his masterpiece was his textbook on conic sections4 ,the work done by ,archimedes on the quadrature of curvilinear figures resulted1 centuries later1 in the discovery of the infinitesimal calculus1 while the theory of conic sections published by ,apollonius led to theories for the solution of problems relating to geometrical curves of all degrees4 ,they placed the geometry of measurements and the geometry of forms and positions on strictly scientific bases4 ,hipparchus applied the new mathematical and geometrical discoveries to astronomy4 ,he found a method for representing the observed motions of the sun1 moon1 and planets by assumed uniform circular motions4 ,his theory of the sun's motion assumed that the earth was not the center of the sun's orbit4 ,he drew a line through the earth and the real center of the orbit and found where the sun's distance is least and where greatest4 ,he then compiled a large set of solar tables giving the position of the sun among the stars at any time4 ,he next turned his attention to the movements of the moon and prepared tables for determining eclipses4 ,then the various planets were studied and their mean motions were calculated and recorded4 ,the stars were mapped and catalogued4 ,he described the apparent movements of #a1jhj stars and comparing his observations and calculations with those of ,aristyllus and ,timocharis1 made #aej years previously4 ,he also discovered the precession of the equinoxes4 ,the astronomical calculations of ,hipparchus led to a great improvement in trigonometrical methods4 ,by using chords1 as we use sines1 and assuming the heavens to be a plane surface1 he fixed the positions of stars 7and similarly geographical points7 by the intersections of lines of latitude and longitude4 ,a planosphere1 an instrument for representing the mechanism of the heavens1 was among the many scientific inventions of ,hipparchus4 ,while ,hipparchus was engaged upon problems in astronomical physics1 ,hero1 a professor of science at ,alexandria1 was working out numerous problems relating to matter and devising machines for practically applying the teachings of mechanical science4 ,ctesibius1 assisted perhaps by his pupil ,hero1 made a large number of valuable engineering inventions4 ,he was an authority on hydraulics and pneumatics4 ,he devised improved siphons1 a pneumatic organ1 a force pump1 a vacuum pump1 a hot-air motor1 and other machines4 ,his studies regarding the physics of gases led him to adopt a molecular theory of matter4 ,he believed that there are vacua existing between the innumerable particles which constitute matter in all its states and forms4 ,ctesibius improved surveying instruments4 ,his dioptra1 an instrument corresponding to a theodolite1 was a plane table set on a tripod1 furnished with compass points and two sights4 ,the plane was adjusted by screws and a water level4 ,this instrument was used by engineers for leveling1 laying out irrigation works and farm lands1 sinking shafts for mining and prospecting purposes1 and for tunneling4 ,a cyclometer for measuring angles of dip and elevation of rock beds and mountains was also used with this instrument4 ,the ,greeks owed much of their knowledge of hydrostatics1 mechanics1 pneumatics1 and physics generally to ,ctesibius4 ,he was not only a great inventor and lecturer1 but also a writer of valuable textbooks dealing with physical and mechanical sciences4 ,hero edited a number of editions of the textbooks of ,ctesibius1 and is credited with inventing some of the theories and machines discussed4 ,he1 too1 published numerous scientific books4 ,hero's work in trigonometry was important4 ,he described a formula for estimating the area of a triangle which still bears his name4 ,he defined spherical triangles and arranged methods for determining the volumes of irregular solids by measuring the water displaced by them4 ,the steam turbine is the best known of ,hero's machines4 ,scholars read much about his wonderful musical instruments operated automatically by pneumatic means resembling the mechanisms of player-pianos1 and particularly about his mechanical toy mimicking a number of singing birds4 ,a group of birds were made alternately to sing and to whistle4 ,the mechanism consisted of air tubes operating various kinds of whistles4 ,a running stream was made to operate an air compressor4 ,the air from the compressor tank operated the various movements of the birds and supplied air for blowing the whistles4 ,the numerous mechanisms of this character which ,hero and his master made indicate that they were as much at home in making pneumatic and similar mechanical toys as is any expert to-day4 ,they not only knew the scientific principles1 but had the engineering and mechanical ability to design them and make them work4 ,hero's fire engine is not as well known as his steam engine4 ,it was a remarkable invention1 however4 ,it was worked by levers and force pumps and resembled the engines still employed by fire companies in some remote rural districts4 ,not the least interesting machine described by ,hero was his slot machine for dispensing wine and other liquids4 ,this machine consisted of a cylindrical container with a slot hole on top through which coins were dropped4 ,beneath this there was a lever with a receptacle for the dropped coin4 ,the weight of a falling coin depressed one arm of the lever and raised the other1 which opened a valve and allowed the liquid to escape4 ,when the lever arm had moved a certain distance1 the coin slipped off and the valve was automatically closed4 ,hero's steam turbine was a crude model4 ,steam was generated in a boiler and conducted through pipes so as to play upon revolving globes or wheel vanes4 ,this machine was invented to operate mechanical toys4 ,it was not until nearly #b1jjj years later that it occurred to an inventor that steam could be used to operate more important mechanism than toys4 ,the next great name in science is that of ,claudius ,ptolemy1 an ,egyptian astronomer1 who lived in ,alexandria about #aci ,a4 ,d4 ,he brought out new editions of the mathematical works of ,hipparchus1 and published a number of scientific books of his own4 ,his principal work1 known as the ,grammar of ,mathematics1 formed the basis of all astronomical studies down to the time of ,copernicus1 about #aejj ,a4 ,d4 ,the earth formed the center of the universe1 according to ,ptolemy's theory4 ,the sun and planets1 he thought1 revolved around the earth4 ,we obtain our minutes and seconds from ,ptolemy's great work4 ,he divided the circle with #cfj degrees and its diameter into #abj divisions4 ,each division of the circumference he divided into sixty parts4 ,the ,latin names for these parts were partes minut prim and secund1 or the first small divisions and the second small divisions4 ,the ,greek scientists were so interested in logical analysis that they constantly investigated the fundamental facts upon which their teachings were based4 ,they made provisional hypotheses1 deduced mathematical consequences1 and compared these with the results of observation and experiments4 ,when ,hipparchus found that his planetary theories did not meet his tests1 he decided to make as many new observations as possible and collect astronomical data to be used at a later period by other scientists4 ,he realized that1 while he knew the old theories were incorrect1 there was not enough data at hand to enable better theories to be established4 ,he therefore deliberately labored to provide data for posterity4 ,ptolemy's treatise on geography was an encyclopedia of places1 names1 and descriptions4 ,in this work he located over #e1jjj places between ,india and ,morocco1 giving their latitude and longitude4 ,ptolemy's textbooks on sound and optics were long celebrated4 ,the work on optics contained valuable chapters on refraction1 a subject he had done much to develop4 ,these works contained some of the finest collections of experimental data illustrating the best scientific methods used in antiquity4 ,the next great mathematicians and physicists are ,pappus and ,diophantus4 ,the former lived about #cjj ,a4 ,d4 ,he was the author of textbooks on mathematics and astronomy4 ,some of these have been preserved and are of great value in exhibiting the status of ,greek science at that time4 ,the arithmetical textbook of ,diophantus1 which is extant1 is remarkable as being the first to contain a complete exposition of algebra and the use of algebraic symbols and methods4 ,euclid solved quadratic equations geometrically and ,hero solved them algebraically1 although without using symbols4 ,but in ,diophantus's arithmetic quadratics are solved by the use of algebraic symbols4 ,after several centuries1 when the ,euclidean geometry was in the ascendant1 and many problems which were suited to arithmetical and algebraic methods of analysis were solved by geometrical and trigonometrical means1 ,diophantus succeeded in renewing interest in arithmetic and mathematics generally4 ,political changes and other intellectual interests soon after the time of ,diophantus turned men's thoughts in other directions and no great scientists were afterward developed by the ,greeks4 ,while the physicists were making their discoveries1 medical men were studying anatomy1 biology1 and materia medica4 ,medical science in the time of ,diophantus had a status1 with a theory and practice1 closely resembling those of to-day4 ,hippocrates of ,cos 7#dfj ,b4 ,c471 was the greatest leader of ,greek medical science4 ,he cast superstition aside and based his researches and practice upon the same principles of inductive philosophy that had proved so valuable in other sciences4 ,he established hospitals for the nursing of the sick1 and had attendants note the symptoms and the histories of the cases4 ,in this way a number of casebooks were made4 ,he wrote a work on ,public ,health4 ,his operations in trepanning were more heroic than would be undertaken by good surgeons to-day4 ,these are described in his book on ,injuries of the ,head4 ,many of his works are extant and furnish very interesting and valuable pictures of the state of medical science in ,greece4 ,during the several centuries in which the ,greeks placed science and all the leading departments of knowledge upon firm bases1 stripped of the sentimental and traditional trappings which had come down from remote times1 changes of a political nature were causing the immigration of foreign peoples to ,greece4 ,the importance of preserving racial purity was not recognized4 ,the result was that the original ,greeks1 who were of the long-headed type1 were forced to give way to the hordes of inferior peoples coming in from ,asia4 ,these new1 round-headed people were not original thinkers1 and were unable to advance science and the arts as the ,greeks had done4 ,they were1 to a large extent1 even unable to appreciate the wonderful treasures of knowledge bestowed upon them by the cultured people they had displaced4 ,the ,egyptians and ,babylonians advanced knowledge for practical purposes and when these were served they showed no desire to explore further4 ,but the analytical mind of the ,greek called for knowledge of basic laws and first principles4 ,,chapter ,,vii ,,the ,,roman ,,and ,,middle ,,ages ,the ,romans succeeded to ,greek culture2 but they were a business people4 ,they exhibited smaller intellectual capacity than the ,greeks for analytical thinking4 ,this precluded them from advancing the sciences4 ,the ,romans attained great eminence in oratory1 history1 art1 and literature4 ,they probably equaled the ,greeks in music4 ,they never produced any great thinkers like ,aristarchus1 ,hipparchus1 ,euclid1 ,ptolemy1 ,archimedes1 ,democritus1 ,hippocrates1 ,plato1 ,aristotle1 and others referred to in the preceding chapters4 ,what the ,romans lacked in intellect they made up in energy4 ,they became good soldiers and sailors1 good politicians1 able architects1 engineers1 and farmers4 ,this explains how they became so powerful politically4 ,they were the most practical people in a practical world4 ,instead of bequeathing us great scientific masterpieces like the ,greeks1 they have left us miles of useful roads1 waterways1 walls1 fortresses1 bridges1 buildings1 and statuary4 ,remains of these objects occur throughout ,europe and northern ,africa1 showing that ,roman engineering practice has been as universally useful as ,roman law and political practices4 ,the great scientific discoveries of the world have been made by only a few peoples4 ,those nations which have possessed the scientific temperament have not always been productive4 ,great inventions and discoveries appear to be made in response to national needs and are preceded by long periods during which the preparatory work is being done4 ,the great men of science being active generalizes1 need the cooperation of many lesser scientists to collect data and observations upon which general theories may be built4 ,this appears to be the explanation of the irregular periods of great scientific activity4 ,julius ,csar1 great in many departments of human endeavor1 carried through two important scientific reforms4 ,he caused the rectification of the calendar4 ,in the year #dg ,b4 ,c4 there was an accumulated error of nearly #he days in the calendar4 ,this was corrected and the year was made to consist of #cfe days1 with an additional day every four years4 ,csar's calendar is still in use4 ,his other reform1 which was not completed until the reign of ,augustus1 was a scientific survey of the ,roman empire4 ,this conferred great benefits not only upon ,rome1 but upon the world4 ,geography1 commerce1 and industry were enlarged1 many practical scientists were trained1 and the various data and maps which had to be collected and drawn resulted in many improvements in statistical methods and in surveying and astronomical computations4 ,an early contribution to science by ,rome was the textbook on ,architecture by ,vitruvius4 ,this great work became the standard guide to building until the changed conditions in the ,middle ,ages called for new architectural methods4 ,the works on natural philosophy by ,lucretius1 the geography of ,strabo1 the books on natural history by ,pliny1 and the encyclopedic medical works of ,galen were successive contributions4 ,these chiefly aimed at developing the teachings of the great ,greek scientists for the practical use of the ,romans4 ,roman history shows that all branches of the learned professions were popular and ,roman professional men were very competent4 ,none1 however1 stands out as a great discoverer4 ,the names just above recorded are those of the chief lights of ,roman science1 and they simply reflect the practical nature of the ,roman intellect4 ,the best the ,romans did was to preserve ,greek science1 test it extensively by practical applications throughout their vast empire1 and hand it on to succeeding nations4 ,philosophical thought in the declining years of ,greece turned to theosophical speculations1 and finally to ethics and theology4 ,much interest was evinced by the ,romans in ethics1 sthetics1 and theology4 ,a new religion1 destined to exert profound influences on intellectual developments1 gradually attracted the attention of thinkers4 ,the ,romans were fascinated by the monotheism of ,christianity and the doctrines of a future life and good will and love4 ,there grew out of the critical attacks on this new theology a powerful scholastic philosophy aiming at the exposition1 systematization1 and demonstration of the principal ,christian doctrines4 ,aurelius ,augustinus1 a native of ,africa 7#cec-dcj ,a4 ,d471 championed the opinion that knowledge of ,god and self was the proper kind to study4 ,the sciences have only value in illuminating the power of ,god4 ,intelligence is necessary to comprehend what we believe2 faith is required to believe what we comprehend4 ,as the highest good1 or moral ideal1 is transcendent1 ,christians cannot realize it1 so human perfection should consist in the love of ,god and bearing good will to others4 ,the conditions brought about by this turn of thought were not favorable for scientific development4 ,the world had to wait until the scholastic philosophy lost itself in metaphysical discussions4 ,then ,roger ,bacon 7#abad-abid7 released science and mathematics from the chains which had so long confined them4 ,while ,european thought was occupied in discussing scholastic philosophy1 the ,arabs and ,moors were carrying on the practice of the sciences4 ,the ,moors in ,spain published many valuable textbooks and developed new principles in architecture and medicine4 ,their ,giralda observatory in ,seville was the first astronomical building erected in ,europe1 and their university in ,cordova remained for a long period the leading professional school4 ,the universities of ,paris1 ,salerno1 ,oxford1 and ,cambridge1 and the law school at ,bologna1 were founded in the eleventh and twelfth centuries and have continued to hold up the torch of science until our time4 ,roger ,bacon1 an ,english ,franciscan monk1 was a graduate of the ,university of ,paris4 ,he was a brilliant student of physical and mathematical sciences4 ,pope ,clement ,,iv invited him to write a textbook of science4 ,bacon did this in #abff4 ,he became a professor in ,oxford ,university in #abfh4 ,his ,opus ,majus 7#abfg7 summarized ancient and current philosophy and science and included the researches of the ,moors4 ,this great book reasserted the fact that science must be based upon experiments and that the astronomical and physical sciences must rest upon geometry and mathematics4 ,bacon's clear recognition of the value of experimental methods and logical exposition mark him as the greatest intellectual force of his century4 ,the errors in the calendar were estimated and corrected by ,bacon4 ,he criticized the astronomical principles of ,ptolemy1 which were still generally accepted4 ,his experiments in physics led him to make important discoveries in optics4 ,he improved lenses and apparently made microscopes and telescopes4 ,he proposed a lunar theory in accounting for the movements of the tides4 ,roger ,bacon made so many accurate comments on physical phenomena and so accurately forecasted recent mechanical inventions that his book1 which was so far in advance of his time that it was unintelligible and caused him to be charged with witchcraft1 still astonishes its readers4 ,lenses were used for spectacles in ,asia in the remotest times1 but there are reasons for believing that ,bacon was the first to prescribe them on scientific principles for the correction of defective vision4 ,he also appears to have appreciated the value of gunpowder as an explosive agent and had it introduced into ,europe from ,morocco4 ,being misunderstood1 ,bacon founded no school and left no students4 ,nicole ,oresme1 ,bishop of ,normandy 7#acbc-achb71 used fractional powers in mathematics and developed a notation4 ,about the same period1 ,thomas ,bradwardine1 ,archbishop of ,canterbury1 wrote on star polygons1 and other ,englishmen1 like ,boethius and ,bath1 wrote new textbooks on astronomy and mathematics4 ,they started a school of trigonometry in ,england that made great improvements in that branch of science4 ,between #abjj and #adjj ,a4 ,d4 the magnetic compass was improved and used at sea1 clocks were improved and made popular1 improvements were made in weaving1 printing was invented1 textbooks were written on many subjects1 and education began to spread in ,europe4 ,all these factors prepared the way for a great industrial and scientific awakening4 ,nicholas de ,cusa 7#adja-adfd71 ,bishop of ,brixen1 published books on mathematics and suggested that the earth's movements indicate a diurnal rotation4 ,the way was now paved for a new theory of planetary motions4 ,nicolaus ,copernicus 7#adgc-aedc7 a ,pole1 developed the astronomical system bearing his name1 as a result of suggestions gained by studying the works of the ,greek astronomer ,hicetas1 and ,plutarch's ,lives of ,greek ,scientists4 ,his great work was entitled ,de ,revolutionibus ,orbium ,celestium1 or the ,movements of ,heavenly ,bodies1 which treated the sun as the center of the planetary system4 ,weather forecasting was improved by ,tycho ,brahe 7#aedf-afja71 and many fine astronomical observations were made by him4 ,he greatly improved astronomical instruments and built and splendidly equipped a great observatory in ,uraniborg1 ,denmark4 ,numerous important observations were made there4 ,john ,kepler1 the discoverer of the ellipticity of the planetary orbits and the laws of their movements1 was a student under ,brahe1 and continued his master's researches4 ,his observations on the movements of the planet ,mars led to his discovery that the planets travel in ellipses and not in circles4 ,besides his numerous works on astronomy he wrote valuable books on optics and other scientific subjects4 ,galileo 7#aefd-afdb7 took up the work of ,tycho ,brahe and ,kepler and carried it forward to new triumphs4 ,he made the first telescope ever used for astronomical observation1 and with it was able to discern that the ,milky ,way was composed of aggregations of innumerable stars2 that the surface of the moon was covered with plains and mountains1 that there were four moons revolving around the planet ,jupiter1 that the planet ,venus showed phases like those of the moon as she moved around her orbit1 and that there were black spots1 at times1 upon the sun1 which revealed its rotation on its axis4 ,galileo did equally fundamental work in developing the laws of motion1 and the principles of mechanism and physics4 ,the development of modern mathematics began with three intellectual feats--the invention of the ,arabic notation1 of decimal fractions1 and of logarithms4 ,the notation was derived by the ,arabs from ,india about #gjj ,a4 ,d4 ,they had used numerals long before1 but the old system was crude like the systems employed by the ,egyptians and ,greeks4 ,the ,textbook on ,mathematics by ,mohammed ibn ,musa1 published at ,bagdad about #hbe ,a4 ,d41 contained the first notable exposition of modern numerals4 ,this important work gave rise to many more ,arabic treatises1 some of which showed improved methods4 ,decimal fractions were used by the early peoples of central ,asia and were transmitted by them to the ,babylonians4 ,their system was based1 apparently1 upon a sexagesimal scale4 ,simon ,stevin 7#aedh-afbj71 a ,belgian1 made great improvements in decimals4 ,he adopted the plan of ,william ,buckley1 of ,england1 and other mathematicians1 and made the base #ajj1jjj1 instead of #fj4 ,john ,napier 7#aeej-afag71 a ,scottish nobleman1 invented logarithms4 ,the story of this great mathematician's work is one of the most interesting in the history of science4 ,napier's first table of logarithms was published in #afad4 ,henry ,briggs 7#aeef-afca71 professor at ,oxford1 made suggestions for the improvement of the tables1 and persuaded ,napier to make the base #aj1 as is now done in tables of common logarithms4 ,briggs published tables in #afbd containing the logarithms to #ad places of decimals for the numbers between #a and #bj1jjj and from #ij1jjj to #ajj1jjj4 ,adrian ,vlacq 7#afjj-affg71 a ,dutchman1 computed the logarithms of the numbers running from #bj1jjj to #ij1jjj1 and thus completed the whole series of logarithms between #a and #ajj1jjj4 ,edmund ,gunter 7#aeha-afbf71 of ,london1 calculated the logarithmic sines and tangents of angles for every minute to seven places4 ,he invented the terms cosine and cotangent and used them in a work published in #afbj4 ,another ,englishman1 ,william ,oughtred 7#aegd-affj71 wrote textbooks on mathematics1 and invented numerous mathematical symbols which are now in general use1 as well as rectilinear and circular slide rules4 ,bonaventura ,cavalieri 7#aeih-afdg7 made many improvements in mathematical formul and expounded a new method of indivisibles which solved some of the difficult astronomical problems raised by ,kepler1 and enabled ,torricelli1 ,viviani1 de ,roberval1 and others to solve abstruse problems relating to all types of curved figures4 ,pierre de ,fermat 7#afja-affe71 one of the greatest of ,french mathematicians1 developed rules for calculating maxima and minima4 ,his functions in this type of equation closely approached those of the differential calculus4 ,the calculus was developed from ,fermat's work by ,lagrange1 ,laplace1 ,fourier1 and other ,frenchmen4 ,pascal and ,fermat developed the theory of probability4 ,pascal worked out many useful methods for dealing with curves4 ,the intense mathematical activity in ,england and ,france resulting from the stimulation given by the invention of ,napier1 prepared the way for the discovery of the infinitesimal calculus by ,newton and ,leibnitz4 ,newton was born in ,england the same year that ,galileo died in ,italy4 ,his greatest work is presented in his celebrated ,principia1 or ,mathematical ,principles of ,natural ,philosophy1 in which the law of gravitation1 the laws of motion1 and the mathematical principles of mechanics are developed4 ,the ,principia was published in #afhg1 and it has ever since been regarded as the corner stone of mathematical and physical science4 ,,chapter ,,viii ,,science ,,in ,,the ,,seventeenth ,,century ,the wonderful advances made in the mathematical1 physical1 and astronomical sciences1 and the invention of many new scientific instruments1 together with the publication of improved textbooks and scientific tables1 like those mentioned in the preceding chapter1 stimulated interest in other fields of science at the beginning of the seventeenth century4 ,medicine1 which failed to advance with the astronomical and physical sciences1 began to improve4 ,the ,moors had established great medical schools in ,spain1 but their teachings were based upon the principles enunciated by ,hippocrates and the ,greek schools4 ,modern medicine was started upon a firm basis by ,john ,harvey 7#aegh-afeg74 ,hippocrates taught that the blood was one of the principal parts of the body--one of the four great humors4 ,its movements1 however1 had never been investigated until ,harvey began to study the functions of the arterial system by the dissection of animals4 ,the arteries had been considered as merely air tubes4 ,this was due to the fact that they were studied only in post-mortem examinations when they were empty4 ,the anatomists of the sixteenth century failed to grasp their importance4 ,harvey1 who was a penetrating observer1 had studied in several continental universities as well as in ,england1 and having an original mind he determined to test the medical theories which he had been taught4 ,his discoveries of the functions of the heart1 the arteries1 and the veins were epochal4 ,he did his work so well and made such simple1 yet telling1 demonstrations that he had less difficulty than his predecessors in getting his teachings accepted4 ,he was soon recognized as the peer of ,hippocrates and ,galen4 ,harvey died without actually seeing the blood coursing from the arteries into the veins1 but four years after his death ,marcello ,malpighi 7#afbh-afid7 exhibited microscopically the passage of blood corpuscles through the minute vessels in the lung of a turtle1 on their way from the heart through the arteries into the veins and returning to the heart4 ,the blood circulation was demonstrated at a subsequent date by applying a microscope to the web of a frog's foot4 ,with low-powered lenses a good view is obtainable in this manner4 ,many other important discoveries were made by ,harvey1 particularly in embryology4 ,he demonstrated that the embryo chicken is formed by gradual development and processes of differentiation and not1 as had previously been believed1 from a minute perfect chicken4 ,microbes were discovered in #afhc by ,antonius von ,leeuwenhoek 7#afcb-agbc71 when he was examining some scrapings from his teeth4 ,he saw for the first time the long and short rods of bacilli and bacteria1 the spirillum and the micrococci4 ,he tried means for destroying them and met with a fair degree of success with a gargle composed of a mixture of vinegar and hot coffee4 ,this experiment was one of the early anticipations of antiseptic surgery1 which was invented by ,lister in the nineteenth century4 ,a ,french surgeon1 ,ambroise ,par 7#aeag-aeij7 was a pioneer in the treatment of wounds4 ,the old method was to use boiling oil4 ,he found that by simply cleaning and bandaging wounds he could get better and quicker results than with hot oil1 which was a very painful treatment4 ,par used ligaments in stopping hemorrhages1 improved the surgery in harelip and hernia operations and for suprapubic lithotomy4 ,he learned the principles of these operations from ,peter ,franco 7#aeje-aegj71 an itinerant surgeon1 who had much skill in operations for kidney and bladder troubles4 ,franz de la ,bo 7#afad-afgb71 a professor in the university of ,leyden1 who is best known under the name of ,sylvius1 the discoverer of the brain fissure of ,sylvius1 founded a new school of chemical medicine4 ,van ,helmont suggested to him the possibility of the stomach being the seat of many common disorders4 ,when this was investigated1 many experiments were made with new medicines4 ,the success of these experiments led to a great reform in medical practice4 ,thomas ,willis 7#afbb-afge71 an ,english physician1 completed the development of the treatments suggested by ,van ,helmont and ,sylvius as a result of their studies of the works of ,harvey4 ,another great ,english medical genius arose to establish the practice of medicine on a scientific basis4 ,thomas ,sydenham 7#afbd-afhi7 founded a school of medicine in accordance with these three principles3 7#a7 ,accurate descriptions of the courses of diseases1 7#b7 following a fixed method of treatment in each disease1 7#c7 searching for specific remedies for each diseased condition4 ,the results of these teachings were very pronounced4 ,before ,sydenham's time1 the only drug used in medicine was an extract of cinchona4 ,the ,dutchmen above named and ,sydenham discovered many active medicinal substances4 ,sydenham's principal discovery in materia medica was that of the properties of laudanum4 ,william ,gilbert1 court physician to ,queen ,elizabeth of ,england1 while ,galileo and ,stevin were developing the laws of gravitation and hydrodynamics1 undertook the investigation of the laws of terrestrial magnetism and chemistry4 ,his researches in chemistry were extensive and valuable4 ,his fame1 however1 was perpetuated by his study of magnetism and electricity4 ,he found that the earth is a vast magnet with north and south poles4 ,his remarkable textbook on magnetism covered many of the fundamental facts known to-day4 ,he noted the distinction between magnetism and electricity1 described electrical charges1 the principles of conductivity and methods for magnetizing iron4 ,galileo wrote of him3 ,i extremely admire and envy this author4 ,the mercurial barometer and its laws were discovered by ,evangelista ,torricelli 7#afjh-afdg7 a student of ,galileo4 ,by means of his barometer1 ,torricelli was able to make great advances in knowledge relating to the physics of the air and to gas pressures1 and he investigated the principles of hydraulics4 ,the microscope1 telescope1 sextant and other instruments were greatly improved by him1 and his mathematical work ranks only second to his contributions to experimental science4 ,the ,torricellian tube1 used as a barometer1 was a means of creating a vacuum1 which was formed at the top of the column of mercury4 ,pascal1 the ,french mathematician1 took up the study of the physics of the vacuum and published an important work on his own experiments4 ,these and other experiments made by ,european scientists prepared the ground for1 and suggested1 the investigations of gases and vacua by ,boyle1 ,mariotte1 and others which finally resulted in the invention of the steam engine and many other modern machines4 ,robert ,boyle 7#afbg-afia7 published at ,oxford in #affj a book which distinguished between chemical compounds and chemical mixtures4 ,he adopted the use of the term gas1 which was first proposed by ,van ,helmont1 and made some valuable studies on the physics of boiling and freezing4 ,the oxidation of metals1 the results of calcination1 and of the fusing of metals and alloys1 calculation of the atmospheric pressure1 a study of colors as affected by light rays1 and investigations in electricity were among the scientific works carried out by this great experimenter4 ,but his fame rests mainly upon the results of his researches on gases4 ,boyle began life as an alchemist and died a well-trained chemist4 ,edme ,mariotte1 a ,french contemporary of ,boyle's1 carried out similar experiments and assisted in formulating the physical laws of gases bearing the names of ,boyle and ,mariotte4 ,a ,german physicist1 ,otto von ,guericke 7#afjb-afhf71 also followed up ,boyle's work and invented a new form of air pump4 ,he also carried on important experiments in electricity4 ,gilbert1 ,harvey1 ,van ,helmont1 ,torricelli1 ,boyle1 ,mariotte1 and other similar pioneers in scientific methods not only invented numerous valuable instruments and wrote suggestive textbooks1 but advanced scientific learning and the love of it by their delightful accounts of their experiments4 ,modern education started with these men4 ,before this period there had been a sterile age in which the fundamental purpose of education was only to teach men how to protect the soul and to serve ,god4 ,this humanistic principle1 however1 failed to advance knowledge of the laws of nature1 and the researches of the scientists gradually caused a strong reaction against it4 ,this in turn resulted in further advances being made1 not only in the sciences1 but in all departments of learning4 ,the way was paved for the era of naturalism1 developed by ,hobbes1 ,locke1 ,descartes1 ,voltaire1 ,kant1 ,rousseau1 and others4 ,naturalism aimed at explaining all phenomena in the simplest terms1 and correlating all things by universal principles4 ,it has received a great impetus in modern times from the ,darwinian theory of evolution4 ,the great scientific discoveries of the sixteenth and seventeenth centuries had other important educational effects4 ,they led to professional specialization and the founding of scientific institutions1 schools1 and universities4 ,the ,lyncean ,society of ,scientists was founded in ,italy in ,galileo's time4 ,it subsequently became1 in #afeg1 the ,accademia del ,cimento4 ,the ,royal ,society of ,england was organized about #afde and chartered in #affb4 ,it did much valuable scientific work from its inception4 ,it has assisted the foremost scientists in their work1 directed scientific researches1 and financed the printing of scientific records and the carrying out of foreign expeditions4 ,nearly all the leading countries in the world have formed institutions with similar aims4 ,the chemical discoveries of ,boyle attracted widespread attention and led to investigations started with the view of discovering the constitution of matter4 ,hermann ,boerhaave 7#affh-agch7 of ,leyden1 took up the study of organic chemistry4 ,stephen ,hales 7#afgg-agfa7 did similar work in ,england4 ,both of these chemists invented valuable laboratory processes and instruments4 ,hales improved the pneumatic trough used for collecting gases4 ,scientists were now furnished with the telescope1 compass1 sextant1 microscope1 barometer1 thermometer1 air pump1 manometer1 and other instruments so that cellular structures of plants1 animals1 and insects1 the microbes and bacteria1 the animalcul found in water and in the sea1 as well as the phenomena of the air1 sky1 and earth crust could now be studied by trained observers4 ,the invention of these instruments caused workers to specialize more and more1 and completely severed science from philosophy1 of which it had been an appendage since the earliest times4 ,the microscopical investigations of ,malpighi1 ,kircher1 ,leeuwenhoek1 ,grew1 and ,hooke opened up an immense field for research4 ,they developed microscopical chemistry and anatomy1 and changed the prevailing ideas regarding animal and vegetable tissues4 ,the sciences of mineralogy1 botany and entomology were benefited and the medical sciences were practically revolutionized4 ,the first publications of the ,royal ,society show the widespread attention microscopical and telescopic studies were then receiving4 ,illustration3 ,copyright1 ,keystone ,view ,co4 ,,weather ,,and ,,astronomical ,,instruments ,,on ,,the ,,roof ,,of ,,greenwich ,,observatory1 ,,england ,illustration3 ,courtesy

7#afdf-agaf71 in ,england1 ,france1 and ,germany1 respectively1 lent powerful aid to the advance of science at this time4 ,bacon's great learning enabled him effectively to describe scientific methods and to direct scientific criticism4 ,he attracted general attention to scientific methods based on inductive processes4 ,descartes1 seeing that the world's best intellects had long been exercised with philosophy and metaphysics1 without discovering anything with certainty1 resolved to accept no beliefs upon the authority of any name or reputation4 ,he would reach his own conclusions based upon the scrupulous examination of data4 ,he hoped to solve the mysteries of nature by the aid of mathematics and geometry1 and developed the ,cartesian philosophy4 ,the mathematical works of ,descartes are now better known than his general scientific ideas4 ,he published in #afcg his ,discourses on ,method and on ,geometry4 ,in the last-named work1 suggestions are given for the development of analytic methods4 ,it has been said of his formul that they are even cleverer than himself4 ,the general use of his analytic methods by other mathematicians resulted in the solution of many scientific problems that had been handed down for centuries as insoluble4 ,descartes also advanced algebra4 ,the application of the doctrine of curved lines to algebra greatly enlarged the scope of its usefulness4 ,in making these innovations1 ,descartes introduced the methods and symbols of modern exponential notation4 ,the ,english mathematician ,wallis was also an important agent in the development of mathematical notation4 ,he based his work on the ,greek notation and that of ,nicolas ,chuquet 7#adhd71 ,j4 ,brgi1 ,thomas ,harriot 7#afca71 ,johann ,hudde 7#afei71 and others4 ,descartes was familiar with the writings of these scholars and1 undoubtedly1 was influenced by them4 ,roberval1 ,fermat1 and ,pascal were contemporary mathematicians in ,france and left great names in the history of the mathematical sciences4 ,they all made contributions which permanently enriched mathematics and made further progress in other sciences possible4 ,the geographical sciences now began to attract attention4 ,the new scientific instruments made it possible to collect data in all parts of the world that was needed in unraveling scientific mysteries4 ,william ,dampier 7#afec-agae7 was one of the pioneers in scientific voyages of discovery4 ,in voyages to the ,orient and ,australasia he collected much important data on zology1 botany1 meteorology1 the winds1 tides1 currents1 and on fish and sea life4 ,his book on winds became the first great standard work on meteorology4 ,the doctrine of spontaneous generation had long held sway in ,europe4 ,the ,greeks entertained it and it was accepted as true in the time of ,martin ,luther4 ,francesco ,redi 7#afbf-afig71 an ,italian biologist1 showed that when the flesh of dead animals is protected it remains fresh4 ,the ,abb ,spallanzani 7#agbi-agii7 carried ,redi's theory further and showed that microbes and bacteria do not develop in concoctions which have been boiled and sealed4 ,here we note the beginning of antiseptic science4 ,under the leadership of ,bacon in ,england1 ,calvin in ,france1 ,luther in ,germany1 and ,knox in ,scotland1 ,european thought was being stirred up while the great discoveries just related were being made4 ,just as ,boyle's chemical discoveries caused the divorcing of chemistry from alchemy1 and the naturalistic philosophy of the times led to the specialization of scientists and the breaking off of philosophy from science1 so the intellectual awakening aroused by ,bacon and his contemporaries led to the suppression of belief in witchcraft and to revolutionary ideas in religion and ethics4 ,locke endeavored to base a rational ,christianity on the ground of experience4 ,until his times1 theology was tangled up with a maze of physical problems which dismayed even such intellects as those of ,newton1 ,hume1 and ,locke4 ,newton's researches were chiefly based upon mathematical and astronomical problems4 ,while a student at ,cambridge in #affj1 he studied the works of ,descartes1 ,kepler1 ,van ,schooten1 ,barrow1 and particularly those of the ,greek and ,british mathematicians4 ,the works of ,j4 ,wallis were very valuable to him4 ,the ,arithmetic of ,affinities of ,wallis drew his attention to astronomical problems and thus led to his great triumphs later on4 ,newton's ,principia has already been referred to as being one of the greatest works of the intellect ever produced4 ,the result of ,newton's meditation upon the nature of the central force that keeps the planets in their courses was that he furnished a mathematical basis for ,kepler's laws by proving that if the planets describe elliptical orbits about the sun1 the force acting toward the sun1 keeping them in revolution1 must vary inversely as the square of the distance4 ,on the revolution of the moon around the earth he found a practical confirmation of this law of gravitational attraction4 ,he then took up the study of motion in general and showed that every particle of matter attracts every other particle in accordance with the same principle of inverse squares4 ,botanical gardens were established in ,padua in #aede1 and not long after in ,pisa1 ,leyden1 ,paris1 and ,london4 ,much attention was devoted to medicinal plants1 and numerous herbal books were published4 ,malpighi1 ,grew1 and ,camerarius 7#affe-agba7 published works on botany and plant morphology4 ,ray and ,linnus 7#agjg-aggh7 studied the classification of plants and compiled textbooks of descriptive botany4 ,buffon 7#agjg-aghh7 published his famous ,natural ,history of ,animals which did for zology what the works of ,linnus did for botany4 ,looking backward1 we can now see that all scientific knowledge has been gained by the trial and error method and cumulative analyses of a multitude of observations4 ,progress is not made uniformly but in a recurrent1 cyclic manner4 ,reactions follow advances1 but in the end all goes forward4 ,,chapter ,,ix ,,prelude ,,to ,,modern ,,science--,,the ,,eighteenth ,,century ,when the eighteenth century opened science had begun to make men think1 and the works of the great scientists had changed the trend of thought on all sides4 ,liberty of conscience1 of worship1 and of opportunity were demanded1 as well as representative government1 economic freedom1 and individual equality before the law4 ,men wanted to be free agents4 ,the philosophical writings of ,berkeley1 ,locke1 ,hume1 ,spinoza1 ,voltaire1 ,rousseau1 and others supplemented the books of the scientists and promoted rational thinking4 ,syllogistic reasoning displaced the practice of accepting beliefs upon authority4 ,this change in public thought reacted most favorably upon science4 ,gottfried ,wilhelm ,leibnitz 7#afdf-agaf7 conceived matter as a plurality of simple forces4 ,many kinds of matter1 he said1 exist4 ,there is no single natural force1 but an infinite number4 ,each force is represented by some individual substance4 ,force is indivisible1 immaterial1 and unextended4 ,simple forces he called essential forms1 units1 atoms1 or monads4 ,the monads are not mathematical points1 nor physical points4 ,real points are metaphysical4 ,in other words1 ,leibnitz created a philosophy of eternal force atoms4 ,the ,greeks were taught by ,leucippus1 ,empedocles and ,anaxagoras that matter is formed of atoms4 ,space is infinite2 atoms are indivisible4 ,atoms are in a continuous state of activity4 ,atoms constitute worlds and planets4 ,falling through space they give rise to eddying motions by mutual impact4 ,many philosophers rejected these views4 ,throughout the ages1 however1 they were learned by students and when ,leibnitz advanced his new atomic theory1 the world was ready to consider it4 ,the ,leibnitzian monads were like ,plato's ideas--eternal purposes4 ,aristotle held that monads are absolute1 indivisible beings4 ,leibnitz suggested that each monad is in process of evolution and realizes its nature through inner necessity4 ,it is not determined from without4 ,each form of matter existed in germ in an embryo4 ,nothing in a monad can be lost1 and future stages are predetermined in the earlier stages4 ,each monad is charged with the past and big with the future4 ,the biologists at this period generally accepted this incasement theory4 ,caspar ,f4 ,wolff suggested1 in #agei1 that there is an epigenesis or a progressive evolution and differentiation of organs from a homogeneous primitive germ4 ,this view did not meet with approval until ,darwin published his great discoveries in the middle of the last century4 ,the history of the atomic theories furnishes a clear illustration of the long period of preparation that great scientific ideas must pass through before they are united by a generalizing genius of exceptional capacity and launched in the form of a new theory4 ,modern mathematical science grew out of the analytical geometry of ,descartes4 ,he showed that the true method for the discovery of scientific facts was to accept nothing as true which was clearly not recognizable as true4 ,all assumptions should be proved4 ,each difficulty should be separately studied4 ,no intermediate steps should be skipped1 and details should be methodically enumerated4 ,thoughts must be guided in an orderly manner1 beginning with the simplest characteristics of an object and proceeding in a logical sequence to the most complicated aspects of each subject4 ,descartes carried out his own rules in his work4 ,his improvements in the differential calculus1 and those in the integral calculus made by ,cavalieri1 and in the calculus of probabilities by ,pascal and ,fermat1 furnished scientists with instruments capable of solving almost every physical problem met with in their investigations4 ,one of the first results of the new analytical methods was the establishment of the science of optics4 ,newton demonstrated that white light is composed of rays of various colors1 and that the color reflected by any object is due to the ability of the object to reflect certain rays while absorbing the rest4 ,the ,dutch physicist1 ,huygens1 championed the undulatory or wave theory of light4 ,refraction was explained by both ,newton and ,huygens1 and the latter1 while studying the double refraction of crystals of ,iceland spar1 discovered the phenomena of polarization4 ,boyle's chemical discoveries led to much research in chemistry4 ,black1 ,bergman and ,van ,helmont investigated the properties of carbonic acid gas4 ,joseph ,black treated limestone with acid and collected the gas evolved in a ,hales pneumatic trough4 ,he weighed the gas and the remainder of the limestone1 finding that what the limestone lost was equivalent to the weight of the gas4 ,he then reversed the process and succeeded in making chalk from a solution of lime4 ,this simple experiment paved the way for chemical analysis and syntheses which have added profoundly to our knowledge of the composition of matter4 ,bergman tested ,black's gas with litmus and found it gave an acid reaction and in #aggi ,lavoisier demonstrated that it consisted of carbon and oxygen4 ,priestley and ,cavendish1 both ,english chemists1 then took up this study4 ,cavendish treated iron1 tin1 zinc1 and other metals with sulphuric acid and discovered a new gas which he termed hydrogen4 ,rutherford discovered nitrogen in #aggb and ,priestley isolated nitric oxide1 and in #aggd discovered oxygen4 ,in the course of his experiment ,priestley also discovered ammonia1 sulphur dioxide and other chemicals4 ,his greatest achievements1 however1 were the isolation and recognition of oxygen1 and the discovery of the composition of water4 ,following up these discoveries1 he noted that the air is not a simple elementary substance1 but a mixture of nitrogen and oxygen with several impure gases4 ,the work of this great chemist became as fruitful in the chemical field as that of ,newton in physics1 astronomy1 and mathematics4 ,carl ,wilhelm ,scheele1 a ,swede1 carried out many experiments which resulted in the discovery of tartaric acid1 the decomposition of silver chloride by light1 magnesium nitrate1 magnesia1 microcosmic salt1 and sulphureted hydrogen1 chlorine1 hydrofluoric1 and other inorganic acids4 ,he also discovered the following organic acids3 lactic1 gallic1 pyrogallic1 oxalic1 citric1 malic1 mucic and uric4 ,he isolated glycerin and sugar of milk and determined the nature of hydrocyanic acid1 borax1 plumbago1 ,prussian blue1 and other chemicals4 ,he invented many new chemical and laboratory processes4 ,scheele was an apothecary's assistant and lived in poverty4 ,but although his experiments were conducted under disadvantageous circumstances his discoveries ranked him as the greatest chemist of his time and one of the greatest chemical experimenters of all time4 ,cavendish established the proportions of the constituents of air1 demonstrated the nature of water and its volumetric composition4 ,the character of the experiments conducted by ,cavendish1 his elegant methods of weighing1 measuring and calculating have caused him to be looked upon as the founder of systematic chemistry4 ,he was more scientific in his methods than the brilliant ,lavoisier1 and much more learned and philosophical than the practical ,scheele4 ,while the chemists were making these great advances there were important developments in physical science4 ,benjamin ,franklin 7#agjf-agij71 the first ,american scientist to acquire world-wide fame1 announced that lightning was an electrical phenomenon4 ,in #ageb he showed by his famous kite experiments that atmospheric and machine-generated electric charges are of a like nature4 ,franklin suggested to ,cavendish certain electrical experiments with a view to studying the electric force between two charges4 ,these experiments led ,cavendish to the discovery of the law of electric attraction between charged bodies4 ,franklin subsequently discovered the law of conservation of an electric charge4 ,charles ,augustin ,coulomb 7#agcf-ahjf7 rendered great service to electrical experimentation4 ,he resurveyed the experiments of ,cavendish1 ,priestley1 and other pioneer electricians1 and established a theory of molecular magnetization which provided a working formula to explain electrical currents and magnetic fields4 ,simeon ,denis ,poisson 7#agha-ahdj7 discovered the law of induced magnetism which bears his name4 ,luigi ,galvani 7#agcg-agih7 observed that the limbs of a frog are convulsed whenever they are connected up through the nerves and muscles with a metallic arc formed from more than one metal4 ,he thought the convulsions were due to a peculiar fluid which he called galvanism1 or animal electricity4 ,another ,italian1 ,alessandro ,volta 7#agde-ahbg7 discovered and explained the theory of the voltaic pile4 ,nicholson and ,carlisle discovered frictional electricity while ,william ,cruickshank showed that a voltaic current decomposes solutions of metallic salts4 ,william ,hyde ,wollaston used ,cruickshank's discovery to prove that frictional and voltaic electric currents are identical4 ,humphry ,davy 7#aggh-ahbi7 in #ahjg established a new voltaic theory which combined the chemical and contact theories previously held1 and showed that electrical and chemical attractions are produced by similar causes4 ,chemical affinity he found to be an essentially electrical phenomenon4 ,francis ,hawksbee1 in #agje1 communicated to the ,royal ,society a monograph which showed that when common air is passed over mercury in a well-exhausted receiver an electric light is produced4 ,this was the first demonstration of the availability of electricity for the production of light4 ,dufay 7#afii-agci7 described positive and negative electric currents4 ,watson determined1 for the ,royal ,society1 the velocity of an electric current and found it practically instantaneous4 ,these1 and numerous lesser1 discoveries did for electricity what the chemical discoveries of ,priestley1 ,cavendish1 ,scheele1 ,boyle1 ,lavoisier1 and others had done for chemistry4 ,the numerous voyages of discovery in the eighteenth century helped to develop the geographical sciences4 ,special expeditions were fitted out for the acquirement of geographical knowledge without any thought of trading profits4 ,the ,jesuits carried out a valuable survey of ,china and ,mongolia early in the century4 ,a ,danish scientific expedition studied ,arabia1 the results of which were published by ,niebuhr in #aggb4 ,james ,bruce visited ,abyssinia with the view of solving the ancient problem of the source of the ,nile4 ,mungo ,park studied the course of the ,niger4 ,captain ,james ,cook led a scientific expedition to ,tahiti with the object of making astronomical observations4 ,this resulted in one of the greatest and most valuable voyages of discovery in history4 ,cook determined the westernmost point of ,america in #aggh and his accounts of ,bering ,sea and ,alaska revived interest in the ,polar seas1 which resulted in numerous ,arctic and ,antarctic expeditions yielding rich scientific returns4 ,the ,hudson's ,bay ,company sent out many investigators to determine the characteristics and resources of ,arctic ,america4 ,the ,russians did the same for their own northern lands4 ,these activities of geographical investigators led to improved methods of navigation1 nautical surveying1 sounding and shipbuilding1 besides supplying an enormous amount of scientific data4 ,the ,british naval authorities pointed out to ,king ,charles ,,ii the need for correct nautical tables4 ,flamsteed1 one of the leading astronomers of the day1 was appointed ,astronomer ,royal in #afge1 with the definite object of producing a new catalogue of star positions1 tide tables1 and other nautical data4 ,he immediately founded the ,greenwich observatory1 which has supplied the world with data for the navigator4 ,bradley1 a successor of ,flamsteed at ,greenwich1 made many important astronomical discoveries while carrying on the star maps4 ,he discovered the aberration of light and the mutation of the earth's axis4 ,locaille studied the parallax of the sun and made numerous stellar observations at the ,cape of ,good ,hope in #agea4 ,he located the positions of #aj1jjj stars in the southern hemisphere4 ,measurements were made in ,peru1 ,lapland1 and elsewhere to discover data regarding the earth's curvature4 ,pendulum observations to detect variations of gravity were made in many countries4 ,maskelyne1 the astronomer royal1 made observations on the transit of ,venus at ,st4 ,helena in #agfa4 ,on this expedition he perfected the method of finding longitude at sea by lunar distances4 ,sir ,william ,herschel discovered the planet ,uranus in #agha1 and subsequently found its satellites4 ,many star groups1 double stars and nebul were discovered by him and he found that the solar system is traveling through space in the direction of a point in or near the constellation of ,hercules4 ,greenwich observatory was publishing at the end of the eighteenth century the ,nautical ,almanac1 and annual reports on star and meteorological observations as well as important astronomical monographs4 ,similar publications were founded in the next century in ,france1 ,germany1 and ,italy4 ,the discoveries in mathematics during the eighteenth century included the differential1 integral1 and other forms of the calculus1 differential equations1 and various formul for dynamics1 mechanics1 and physical and astronomical calculations4 ,euler1 ,lagrange1 ,laplace1 ,d',alembert1 and ,carnot were prominent mathematical investigators4 ,heat in earlier times had been regarded as an imponderable substance called caloric which was supposed to be emitted by hot and absorbed by cold bodies4 ,thus the expansion of mercury was explained by the addition of caloric and not by the increase of distance between the molecules4 ,francis ,bacon and the ,scotch chemist ,black did the preliminary work which enabled ,count ,rumford finally to establish the true theory of heat4 ,watt and ,newcomen were attracted by these studies and reduced their theories to practice in the steam engine4 ,black described specific and latent heat and invented1 and used1 the calorimeter bearing his name4 ,hall invented an achromatic lens for telescopes in #agcc1 and ,dollond1 another ,english optician1 improved achromatic lenses and made1 in #ageh1 achromatic telescope objectives4 ,the lenses were primarily designed for astronomical telescopes1 but they were also applied to microscopes and other scientific instruments1 resulting in improvements in our knowledge of light4 ,the voyages of discovery1 in this century1 encouraged study of zology and natural history subjects generally1 including mineralogy and geology4 ,hooke1 ,ray1 and ,woodward made collections of rocks and fossils in ,england and advanced hypotheses to explain their origins4 ,lazzaro ,moro suggested that fossils must have been deposited in rocks when they were being formed4 ,he also distinguished rock formations by the characteristic fossils found in them4 ,hutton and ,smith then made scientific studies of ,english rocks1 fossils1 and earth sculpture1 and prepared the materials for the subsequent brilliant discoveries of ,lyell4 ,the first governmental school of mines was established in ,freiberg1 ,saxony1 in #agge4 ,this institution1 and others which were afterward established in different countries1 led to an intensive study of the geological and metallurgical sciences1 which eventuated in great advances during the nineteenth century4 ,aristotle and ,theophrastus in early times1 ,gesner in the sixteenth century1 ,ray1 ,grew1 ,malpighi and ,willughby in the seventeenth century1 had been the writers of the principal textbooks on zology4 ,buffon 7#agjg-aghe7 and ,linnus 7#agjg-aggh7 were the founders of modern natural history in the eighteenth century4 ,buffon described species1 while ,linnus classified them4 ,linnus named ,homo sapiens as a distinct species in the order of primates which includes apes1 lemurs1 and bats1 and fixed man's place in nature4 ,the medical sciences were revolutionized by the researches of ,edward ,jenner4 ,he applied the scientific methods of the chemists1 mathematicians1 and astronomers to medicine and through accurate observation1 skillful experimentation1 careful generalization1 and thorough verification1 founded preventive medicine4 ,his discovery of vaccination as a preventive for smallpox1 communicated to the ,royal ,society in a very interesting paper in #agih1 was the pioneer of the many brilliant advances of our day4 ,the ,freiberg ,school of ,mines1 the ,woolwich ,observatory1 the ,school of ,civil ,engineering in ,paris 7#agdg71 the ,universities of ,gttingen 7#agcg71 ,bonn 7#aggg71 ,brussels 7#agha71 ,yale 7#agja7 and ,princeton 7#agdf7 were founded in this century4 ,modern industrialism began in the final part of this century4 ,the invention of the steam engine by ,watt resulted in giving the greatest impulse to material civilization the world ever experienced4 ,this invention was the direct result of the experimental work of ,boyle1 ,newton1 ,black1 ,cavendish1 ,davy1 ,priestley1 and ,lavoisier4 ,it illustrates how the scientific discoveries of one generation furnish the data for the advancement of knowledge by the next generation and how a single invention may change the whole aspect of life1 giving employment for vast numbers of people1 developing settlement in foreign lands1 starting new industries1 and extending the fields of commerce4 ,the history of the development of the steam engine from the results of a few basic physical researches by ,british scientists forms one of the grandest stories in the history of science4 ,the new aspect assumed by the world as a result of the great scientific discoveries and the increases in industry and commerce which followed them seemed strange to the people who were unused to rapid progress4 ,there was a disturbed feeling akin to fear abroad while the new ideas were being popularized and disseminated throughout the world4 ,the movement in favor of enlightenment was strongest in ,france because of the social1 political1 and religious oppression of the people4 ,it ended in the ,french ,revolution1 which strengthened the respect for reason and human rights throughout the world4 ,,chapter ,x ,,physical ,,sciences ,,in ,,the ,,nineteenth ,,century ,during the nineteenth century1 the path of scientific discovery might almost be represented by a vertical line4 ,never before was such rapid and marvelous progress made4 ,the releasing of the mind from the oppressive restrictions of earlier conservative ages liberated the intellectual energies of mankind4 ,a new idealistic philosophy supplanted that of an earlier period and universal attention was given to science and material things4 ,amidst these changes social science was devolved1 and1 with it1 the study of psychology4 ,but it was the physical sciences which most felt the stimulus of the new rationalistic spirit4 ,the relationships between physical magnitudes are established by measurements4 ,when these are accurately ascertained1 questions regarding their variable functions can be solved by mathematical principles4 ,physics is thus linked with mathematics through measurements4 ,the more science advances1 the greater is the accuracy needed in physical measurements4 ,the strictness and clearness of experimentation which has been attained in physics has given birth to a science of measurement1 which has its own instruments1 rules1 methods1 and formul4 ,measurement of length is one of the bases of physics4 ,it is a relative operation carried out by comparing the length of one body with that of another4 ,standards of length are preserved by a ,bureau of ,weights and ,measures in most countries4 ,delambre1 a ,french authority on the decimal system of measures1 taught at the beginning of the nineteenth century that magnitudes as small as the hundredth of a millimeter are incapable of observation4 ,the ,international ,bureau of ,weights and ,measures now guarantees to determine two or three ten-thousandths of a millimeter4 ,so much has the science of measurement progressed in a century4 ,the undulations of light rays are used for determining standard lengths4 ,michelson and ,benoit measured a standard length of ten centimeters1 in #ahid1 in terms of the wave lengths of the red1 green1 and blue radiations of cadmium1 and then in terms of the ,french standard meter4 ,these experiments yielded very accurate results4 ,the measurement of mass is another important base of physics4 ,mass is the quantity of matter in a body and the action which gravity exerts on mass is called weight4 ,weight does not depend entirely upon mass1 but also upon the position of the body weighed1 because when the body is weighed in one place and reweighed in another1 there will be a difference in the force of gravity due to change of latitude and of altitude4 ,national standards of mass have been made of alloys of iridium and platinum4 ,many remarkable measurements of time1 temperature1 and physical constants were carried out during the century4 ,high and low temperature charts were completed1 showing temperatures in the air1 the earth1 and the sea4 ,instruments and methods were devised for measuring any temperature whether of high furnace gases or low freezing mixtures4 ,the measuring units of mass1 length1 time1 and temperature are fundamental1 others like velocity1 acceleration1 power1 and area are referred to them4 ,for that reason the latter are called derived units4 ,many of these are important and call for accurate determinations4 ,one of the first achievements of the century was the establishment of the doctrine of the conservation of energy4 ,francis ,bacon had suggested that motion is a phenomenon of heat1 and ,newton had divined the principle of the conservation of energy1 but it was ,benjamin ,thompson1 ,count ,rumford1 who discovered the nature of friction and made the first estimate of the mechanical equivalent of heat4 ,sir ,humphry ,davy showed that two pieces of ice could be melted by simply rubbing them together1 in a vacuum4 ,but he failed to draw the great inference that this experiment warranted4 ,if he had observed that the heat could not have been supplied by the ice because ice is an absorber of heat1 he would have anticipated the great work done by ,james ,p4 ,joule1 an ,english physicist1 who published the results of many experiments carried out by him prior to #ahdc4 ,his task was to find the exact mechanical equivalent of heat4 ,his best results were secured by dropping a mass of lead from a measured height and using the energy generated during the descent to operate a revolving paddle in a dish of measured water4 ,delicate thermometers recorded the increase of temperature in the water and showed that the descent of #dbd grams of lead through a distance of one meter1 or one gram of lead through #dbd meters1 generated sufficient heat to raise one gram of water one degree centigrade 7#a ,c474 ,otherwise expressed1 a fall of #ggb lbs4 of lead through a distance of #a foot1 or #a lb4 of lead through #ggb feet1 raises the temperature of #a lb4 of water one degree ,fahrenheit 7#a ,f474 ,these #ggb foot-pounds1 or #dbd gram-meters1 represent the mechanical equivalent of heat upon which so many important theories have been based4 ,but ,joule's equivalent was determined for common air temperatures whereas the specific heat of water increases with the temperature so that the value of the equivalent rises with increased temperatures4 ,osborne ,reynolds1 in #ahig1 found the mean equivalent for temperatures between the freezing and boiling points to be #ggg foot-pounds4 ,the discovery of ,joule's equivalent established a relationship between motion or mechanical work performed and the amount of heat generated when work is completely expanded in friction4 ,the same relationships continue good when the work is transformed by indirect means as by generating electric currents or expanding gases4 ,the multitude of elegant experiments used to confirm the truth of ,joule's law showed that heat is not a substance1 or calorie1 but a purely mechanical effect4 ,this great discovery of the relation of friction and heat lies at the basis of electricity1 molecular physics1 and chemistry1 and is the source of the formul used by engineers in designing power machinery4 ,the internal combustion engine is largely a result of the discovery of ,joule's equivalent and the physical theories derived from it4 ,this great discovery caused a new theory of matter to be developed4 ,dalton had suggested1 when applying the atomic theory to chemistry1 that when two elements combine to form a third substance1 it is probable that one atom of one element joins itself to one atom of the other1 unless some exceptional condition exists4 ,when water is formed by bringing oxygen and hydrogen together1 he supposed that one atom of oxygen combined with one atom of hydrogen4 ,gay-,lussac subsequently proved that not only does one volume of oxygen combine with two volumes of hydrogen 7not one as ,dalton believed7 in the production of water1 but that nitric and carbonic acid gases combine with ammonia gas in the ratio of #a3a or #a3b4 ,he also demonstrated that one volume of nitrogen united with three of hydrogen form ammonia1 and that carbonic oxide burning in a mass of oxygen consumes half its volume of oxygen4 ,he concluded from these and other facts that gases always combine together in simple proportions by volume and that the apparent contraction of volume they show on combining bears a similar simple relationship to the volume of one or more of the gases4 ,avogadro1 working on ,gay-,lussac's experimental data1 suggested that the number of integral molecules in any gas is always the same for equal volumes1 or is always proportional to the volumes4 ,he also suggested that equal volumes of different gases at the same pressure and temperature contain the same number of molecules4 ,experiments on alcohol made by ,williamson raised doubts as to the validity of ,avogadro's hypotheses when applied to chemical combinations4 ,these doubts were cleared in #ahfj1 when the new chemical atomic weights and formul were introduced into ,english textbooks4 ,the molecular theory of matter derived from these experiments supposes that all visible forms of matter are aggregations of simpler and smaller chemical elements4 ,mendeleff and ,newlands showed that the physical and chemical properties of the elements are functions of their atomic weights4 ,investigations of radioactivity and the observations based upon the passage of electric currents through gases have recently modified our views with respect to the atomic theory1 but these points will be dealt with in the chapter dealing with radiation4 ,questions regarding the eventual loss of energy in matter are best studied in gases4 ,a considerable number of important investigations are now being carried on in ,europe with the view of tracing the interchanges of molecular energies in gas molecules4 ,maxwell and other investigators found long ago that the motion of molecules cannot go on perpetually4 ,the energy of motion will in time be frittered away by friction1 air resistance1 collisions with other molecules1 vibrations set up by collisions1 and other molecular movements4 ,it has been found that the energy which is dissipated by air resistance is transformed into energy in the air4 ,that which is lost by collisions is converted into internal vibrations within each molecule4 ,the question now arises as to what effects are exerted on a gas4 ,it involves the effects of the communicated internal molecular vibrations and their transference of energy to the surrounding medium4 ,what is known as the ,quantum dynamic theory has been proposed to account for this phenomena4 ,quantum dynamics appear to be distinct from the ,newtonian4 ,carnot and ,clausius discovered that the motive power of heat is independent of the agents brought into play for its realization4 ,the motive power of a waterfall depends1 for example1 on its height and on the quantity of water falling within a given time4 ,clausius stated the ,carnot idea in mechanical terms by saying3 ,that in a series of transformations1 in which the final is identical with the initial stage1 it is impossible for heat to pass from a colder to a warmer body unless some other accessory phenomenon occurs at the same time4 ,a heat motor1 which1 after a series of transformations1 returns to its initial state1 can only supply work1 or power1 if there exist two sources of heat1 and if a certain quantity of heat is given to one of the sources which can never be the hotter of the two4 ,the output of a reversible machine working between two given temperatures is greater than that of any nonreversible engine1 and it is the same for all reversible machines working between these two temperatures4 ,clausius showed that this principle conduces to the definition of an absolute scale of temperature and there is another factor assisting in restoring physical equilibrium which he termed entropy4 ,it is a variable which1 like pressure or volume1 serves concurrently with another variable to define the state of a body4 ,these discoveries of ,carnot and ,clausius showed the impossibility of finding a source of perpetual motion and helped to solve many of the difficulties in securing efficiency from internal combustion engines4 ,industrial1 as well as scientific results of immense importance have developed from these principles4 ,theories on the compressible fluids and elastic equilibrium were developed as the result of work done between #ahge and #ahif by ,j4 ,w4 ,gibbs1 ,helmholtz1 ,duhem1 and others on internal thermodynamic potentials4 ,these theories have proved of incalculable value in elucidating electrical and radiation phenomena4 ,another discovery of ,gibbs1 made in #ahgf1 has also had brilliant results4 ,it is known as the ,phase ,law4 ,the homogeneous substances into which a material system is divided is called a phase4 ,carbonate of lime1 lime1 and carbonic acid gas are the three phases of a system which comprises ,iceland spar partially dissociated into lime and carbonic acid gas4 ,the number of phases1 combined with the number of independent bodies entering into the reactions1 fixes the general form of the law of equilibrium of the system4 ,this discovery of ,gibbs has resulted in greatly extending the field of physics4 ,it is of importance in molecular and atomic investigations1 in osmosis1 electrolysis1 and in most questions dealing with thermodynamics4 ,light is generally defined as the sense impression received by the eye4 ,it was formerly believed that it was caused by streams of corpuscles emitted by the source of light4 ,this was known as the emission theory4 ,early in the nineteenth century1 the undulatory displaced the emission theory4 ,according to this1 light is a transverse vibratory motion extended longitudinally through the ether4 ,the experiments of ,faraday1 ,maxwell1 ,fresnel1 ,hamilton1 ,green1 and others suggested that the undulatory theory required for its validity a new medium different from the atmospheric air and from every substance known to man4 ,just as the results of investigations into reflection1 refraction1 diffraction1 and polarization showed that the old corpuscular theory of light was untenable1 so these experiments seemed to cast doubt upon both the undulatory and emission theories4 ,fresnel1 when studying problems in polarization1 noticed that a theory of light proposed by ,hooke appeared to be true4 ,hooke asserted that light vibrations are not longitudinal but transverse4 ,fresnel found by his experiments that the idea of longitudinal vibrations acting along the line of propagation in the direction of the rays would not explain the polarization changes in light4 ,they suggested that there was a transverse movement perpendicular to the ray4 ,when ,fresnel's researches were published1 physicists realized that if the transverse direction of luminous vibrations was denied the undulatory movement of light would also be denied4 ,now transverse vibrations cannot exist in any medium resembling a fluid1 because it is characteristic of fluids that1 so long as the volume continues constant1 its different parts can be displaced without the appearance of any reaction4 ,this necessitates the assumption that light needs a solid body for its transmission and ,lord ,kelvin asserted that this body must be a solid more rigid than steel4 ,when the vibratory theory was accepted1 it became necessary to investigate the nature of the ether and to determine its characteristic properties4 ,neumann1 ,mac,cullagh1 ,green1 and ,stokes then developed an elastic solid theory of the ether4 ,the experiments of ,lord ,rayleigh1 ,lorentz1 ,drude1 ,larmor1 and others suggested that light is identical with electromagnetic disturbances and1 consequently1 is an electrical phenomenon4 ,some of the finest developments in physics during the nineteenth century were in the realm of electricity4 ,they resulted in an enormous extension of the use of electricity in industry and commerce and led to the investigation of radioactivities of various kinds and these in turn are developing investigations of a most brilliant character4 ,,chapter ,,xi ,,the ,,natural ,,sciences ,manifestations of animal life are everywhere visible4 ,they may be seen on mountain peaks1 in desert plains1 and by the seashores4 ,even the bleak arctic ice fields have their faunas4 ,this extraordinary distribution of life has attracted attention since the dawn of history4 ,primitive man1 by his often beautiful cave drawings1 indicated that he studied intimately the wild life surrounding him4 ,the basic facts of natural history were studied by the early peoples of the ,near ,east4 ,the ,greeks prepared many books on natural history and anticipated modern evolutionary theories4 ,the natural sciences1 however1 made slow progress until toward the end of the eighteenth century when ,linnus and ,buffon began their great works4 ,when the nineteenth century opened1 the broader fields of nature were segregated1 classified1 and described4 ,linnus took broad views regarding the principles of classification based upon general structure1 and his work was enlarged and improved by ,cuvier4 ,buffon contributed suggestions regarding the probable mutability of species with respect to changes in environment1 and improved on the old ,greek evolutionary ideas by formulating a definite theory of the causes of mutability4 ,he was an important agent in promoting the modern theories of evolution in zology and botany1 which have done more than anything else to augment our knowledge of terrestrial life4 ,the numerous scientific exploring expeditions in the eighteenth and nineteenth centuries collected an enormous amount of data regarding animals and animal life4 ,early in the nineteenth century this data was worked up and classified4 ,it soon became apparent that the range of any given species of animal is strictly limited4 ,a new science1 that of the geographical distribution of life1 was developed4 ,this has been very fruitful in defining the true home areas of all species of animals1 insects1 birds1 and fish1 and locating their principal paths of migration4 ,the world has been divided into about a dozen terrestrial life regions1 subregions and transitional regions4 ,these have been mapped and described4 ,the work of ,dr4 ,a4 ,r4 ,wallace1 in #ahgf1 showed the comparative importance and extent of these life zones and their variable richness in zological forms1 the relationships of the species in different zones1 and their degrees of isolation4 ,the descriptions of these great geographical zones fill many interesting volumes and cover all the important forms of existing life4 ,the naturalists who studied particular zones1 or classes of animals1 frequently did extraordinary work4 ,the bird studies in ,north ,america1 recorded in a series of wonderful paintings by ,audubon1 and the studies of ,frbringer and other naturalists1 are comparable with ,wallace's great book on the ,geographical ,distribution of ,animals1 published in #ahgf4 ,the morphological researches of ,parker1 ,huxley1 ,quatrefages1 ,owen1 and others revolutionized many of the subdivisions of natural history and led to important discoveries in biology4 ,the effects of climate upon the development1 migration1 and decline of species and upon the extension and upbuilding of civilization have been minutely studied4 ,kropotkin showed that climatic changes in ,asia drove the hordes of native tribes into ,europe at early periods4 ,they were forced to migrate on account of droughts leading to a food shortage4 ,many historical events have been shaped by climatic factors4 ,just as men who inhabit dry districts are usually nomads on account of their need of seeking new food supplies1 so animals and insects are forced to migrate for a similar reason4 ,the life changes wrought by disease epidemics under climatic influences have also been studied and have shed much light upon the origin and development of many organs and upon the habits of animals4 ,some of the chief inferences arising from investigations on the effects of climatic variations on life are that certain types of climate favor the development of certain animal species2 certain climates have prevailed in historical times in centers where civilization flourished greatly4 ,therefore it may be presumed that definite climatic conditions are required for the specific development of each type of species and for each kind of civilization4 ,just as history shows that one of the many conditions of human progress has changed repeatedly from century to century on account of variations in climatic factors1 so these stimuli have1 from the earliest times1 swayed and modified all classes of organic life4 ,climate serves to develop1 retard1 or extinguish animal characteristics1 habits1 and development4 ,the study of the rle of climate in modifying living conditions has disclosed data which throws much light on the philosophical problems surrounding organic life1 its laws and progress4 ,the voyage of the ,beagle in #ahca1 for a scientific cruise to ,south ,america1 with ,charles ,darwin aboard as naturalist2 that of the ,ross ,antarctic expedition in #ahci1 with ,sir ,w4 ,j4 ,hooker as botanist2 that of the ,rattlesnake for ,australia and the ,south ,seas in #ahdf1 with ,t4 ,h4 ,huxley as surgeon1 resulted in the assembling of scientific data in natural history fields which1 when classified and developed1 revolutionized the natural sciences4 ,the work of the ,challenger1 in #ahgb1 and many other memorable ,british scientific expeditions augmented and confirmed the data collected in the earlier explorations4 ,harvey's explanation of the movement of the blood by the pumping pulsations of the heart quickened interest in biology4 ,mayer and ,helmholtz1 when chemists1 had succeeded in artificially making urea and sugar and investigated living organisms from the viewpoint of mechanisms operated on the principle of the conservation of energy4 ,they traced the manifold functions of the body to chemical and thermal energies developed by the destruction of food4 ,these valuable discoveries were augmented by ,schleiden and ,schwann1 showing that all organisms are built up of living cells4 ,the offices performed within cells by colloids and solutions1 and in the nerves by electric movements1 were traced4 ,investigations into the most minute forms of animal life also furnished startling results4 ,schwann found1 in #ahch1 that fermenting yeast consists of living vegetable cells1 and that organic putrefaction is caused by the activities of such cells4 ,louis ,pasteur 7#ahbb-ahie7 demonstrated that the presence of bacteria in any animal is always due to the entrance of bacteria and microbes from the outside1 or by means favoring the abnormal increase of existing germs4 ,he also showed by experiments that diseases like chicken cholera1 phylloxera1 or the silkworm disease are caused by particular microbes4 ,these discoveries led to the tracing of many common diseases to their special living germs4 ,while these impressive additions to scientific knowledge were being made1 other naturalists were studying the instinctive emotional and intelligent behavior and psychology of animals1 both singly and in herds4 ,animals and insects were found to display signs of intelligence1 sometimes of a high order2 to live socially1 in many cases2 and to play and court with emotional attributes4 ,throughout the animal kingdom1 until man is reached1 animals are guided in their activities by self and racial preservation4 ,play was found to be a fruitful factor in animal education1 even in minute insects4 ,the behavior of any animal does not stand alone1 but is related to that of others4 ,animals which hunt1 or are hunted1 combatants1 rivals1 mates1 and enemies1 react upon one another4 ,entomology1 the science of insects1 has been extensively systematized4 ,practically every phenomenon relating to the insect metamorphosis has been disclosed4 ,the works of ,binet1 ,lubbock1 ,fabre1 and many others have illuminated the psychology of insect life4 ,the charming writings of ,j4 ,h4 ,fabre on the life of a fly1 on the mason bees1 the hunting wasps1 the life of a caterpillar1 of a grasshopper1 of the sacred beetles and other insects1 are as thrilling and instructive as any masterpiece of romantic writing4 ,what could be more interesting than ,fabre's account of his observations on the glowworm1 when he discovered that its luminescence is due to oxidation by air forces through a special lightning tube1 and that it occurs in males as well as females and in the eggs and grubs likewise8 ,he shows that the glowworm's life1 from start to finish1 is one carnival of light4 ,the females are living lighthouses which brilliantly illumine the wild thyme and other flowering plants they haunt on dark nights1 making miniature fairylands in country districts4 ,studies in the growth and form of living bodies have opened up many interesting problems in physical biology4 ,the cell and tissue1 shell and bone1 leaf and flower are various portions of matter1 the particles of which are moved1 molded1 conformed1 or shaped in obedience to the laws of physics4 ,forms like those of the lovely wing scales of butterflies1 of lace flies1 or the spiral shells of the foraminifera are natural diagrams of the results of physical forces4 ,biologists not only study the nature of the motions of living organisms as animal kinetics1 but also the conformation of the organism itself1 whose permanence or equilibrium is explained by the interaction or balance of forces leading to static conditions4 ,the dynamics of cell formation and cell division and their karyokinetic figure drawings are the result of numerous complex physical force struggles brought about by chemical and physiological reactions4 ,studies of these have shown that the spermatozon1 nucleus1 chromosomes1 or the germ plasms1 which develop organic life1 can never act alone4 ,they must be started by other forces which make them seats of energy4 ,the experiments of ,george ,rainey on the elementary formation of the skeletons of small animals1 of ,carpenter upon the formation of shells1 and those of ,professor ,harting on the same subjects1 have shown how lime solutions acting in conjunction with gelatinous substances1 or membranes1 build up the numerous geometric shapes of the frames of so many kinds of primitive organisms1 and the scales of fish or the extraordinarily beautiful markings and sculpture of shells4 ,the application of the ,cartesian coordinates to the outline of organisms1 skulls1 bones1 and organs of animals has opened up a new field of mathematics--biological research which has yielded many results confirming theories based on other data and supplying facts of great interest that may at any time result in the establishment of important generalizations4 ,the fact of beauty in animate nature is so pronounced1 and man's contemplative delight in beautiful things is so natural that investigations have been made into the sthetic emotions of other animals4 ,a vast array of facts has been collected which leaves no doubt of the universal appreciation of beauty4 ,the lovely colors of shells1 butterflies and birds1 the extraordinary beauty of the designs of the frames of the ,foraminifera1 radiolarians and sponges1 the graceful logarithmic spirals of horns and flower and leaf buds1 and the charming flowing lines in the shape of the race horse and gazelle1 these elements of organic beauty which emphasize and enhance the forms of animals1 all contribute to the general embellishment of nature4 ,the combinations of beauty of form1 color1 and movements in parrots1 humming birds1 the fish inhabiting coral reefs1 butterflies1 and orchids1 are always perfect4 ,we likewise find that in all parts of the globe1 and in each life zone1 organic beauty conforms to that of the landscape and the heavens4 ,the biological significance of this universality of beauty in the organic world will be dealt with in the following chapter4 ,the fishes of the seas1 rivers1 streams1 and lakes have been studied1 classified1 and described as completely as the insects of the air1 the field1 the soil1 and those parasitic upon other organisms4 ,the surveys of the ,atlantic have brought to light many types of fish which inhabit only the deepest parts of the ocean4 ,these fish are modified in most extraordinary ways to fit their surroundings4 ,owing to the darkness of their living zones1 they are provided with luminescent appendages which are practically similar to the firefly's and glowworm's electric generators4 ,the lights are formed1 as in the insects1 by the oxidation of material exuded by the fish4 ,there are more than #ahj families of fishes recorded4 ,each family contains an average of twenty genera and each genus about five species4 ,the known species of fish are1 therefore1 between #ai1jjj and #bj1jjj4 ,the ,danish naturalist ,hensen found #bgh1gie1jjj1jjj fecundated fish eggs per square mile in the summer waters of the ,skagerrack4 ,the waters of the seas from the ,arctic to the ,antarctic limits are full of fish eggs as well as those of shellfish and sea organisms generally4 ,this shows that organic life is as abundant in the sea as anywhere on land4 ,just as temperature and salinity are the chief agents of oceanic circulation and current movements1 so they are the leading factors in promoting the organic life of the sea4 ,the vast heterogeneous mixtures of living creatures1 comprising vegetable and animal organisms1 larv1 and eggs of fish and animals1 which are swept hither and thither by the sea tides are called plankton4 ,this term means the living dust or emulsion of the sea4 ,it has been shown that vegetable plankton is composed of bacteria and adult microscopic alg1 largely of the ,diatomace1 ,peridinace1 ,cyanophyce1 and other primary groups4 ,the animal plankton comprises a mass of microscopic creatures belonging to the ,protozoa1 ,radiolaria1 and ,globerigin4 ,there are also immense numbers of tiny1 invisible crustaceans like the ,copepoda1 and eggs and spores of all kinds of fish and alg4 ,these organisms are so dense in certain sea areas that their particular colorations are reflected in the water4 ,the ,red ,sea1 for example1 is colored by a reddish alg2 the ,baltic and ocean areas near ,greenland are colored green by swarms of alg1 and certain tropical seas are often brilliantly colored in the same manner4 ,plankton furnishes fish with nutriment4 ,the study of the movements of plankton1 at seasonal intervals1 has led to the discovery of the causes1 extent1 and results of the migration of the principal commercial fishes4 ,these researches are so valuable that most large nations support marine biological stations and ships to regularly make observations4 ,the ,norwegian naturalist ,srs1 ,sir ,john ,murray1 the ,prince of ,monaco1 and others have furnished accounts of the life histories1 feeding grounds1 metamorphoses and migrations of many fishes1 and have shown how the inhabitants of the plankton masses live upon themselves or produce nitrifying or denitrifying bacteria1 chemicals1 and mineral substances like lime1 phosphates1 and horny membranous material4 ,the development of biology and embryology1 and the peculiar habits and color schemes of certain fish1 insects1 birds1 and animals led to inquiries about design in nature1 the causes of the development of species1 and the instincts and habits of animals4 ,erasmus1 ,darwin1 ,buffon1 ,cuvier1 and others began these studies1 but it was ,charles ,darwin 7#ahji-ahhb71 who by the publication of his ,origin of ,species in #ahei1 first furnished many of the keys to the riddles of organic life4 ,the next chapter will show what has developed from his labors4 ,,chapter ,,xii ,,organic ,,evolution1 ,,variation1 ,,and ,,heredity ,science developed when primitive man began pondering over the problems of the creation4 ,he sought the causes of life1 of the development of life forms1 and the authorship or origin of the uniformity and apparent design in nature4 ,it is1 therefore1 probable that what we now study as the science of organic evolution is one of the oldest of the sciences4 ,as the ages have rolled on1 the origin of life has been explained in turn by theories of3 7#a7 eternity of present conditions2 7#b7 miraculous creation2 7#c7 catastrophism with 7a7 increases by immigration 7b7 increases by successive creations2 and1 finally1 by 7#d7 organic evolution4 ,the term organic evolution means the forming of new combinations of the elements of organisms4 ,it does not mean the arising of an animal or plant out of nothing--a new creation4 ,that idea was exploded long ago4 ,the science which ,darwin started surveys the whole course of natural history in terms of four dimensions--length1 breadth1 depth1 and duration4 ,this was the plan which led ,darwin to his great discoveries4 ,while studying the minor changes taking place in common animals and plants1 and looking over the broad vistas of nature back to the remotest times1 he saw how each year countless weak and ill-adapted plants1 insects1 and animals were killed off4 ,when he reflected that this process has been going on throughout all time1 the idea flashed into his mind that it is through this testing ordeal that adaptability of surviving organisms is derived4 ,one of the grandest conceptions of the human mind is that the apparently complex1 inharmonic system of nature has developed from a simple beginning on a cooled globe from a jellylike cell4 ,the theory of the permanence of species was generally held by biologists before publication of ,darwin's first great book4 ,darwin said that no naturalist of his time doubted the accuracy of the theory of the eternity of existing conditions and they refused to listen to his views regarding the mutability of species4 ,darwin put forth the theory of organic evolution by natural selection and the survival of the fittest4 ,the great beauty of this theory lies in its simplicity and its appeal to agencies which we can see in full operation every day and night4 ,the skillful manner in which ,darwin marshaled data to substantiate his theory quickly converted the scientific world1 and led to revolutionary changes in the general tendencies of knowledge1 and in practically all fields of human activity4 ,darwin's terse statement of his conception was3 ,as many more individuals of each species are born than can possibly survive1 and as consequently there is a frequently recurring struggle for existence1 it follows that any being1 if it vary in any manner profitable to itself1 under the complex and sometimes varying conditions of life1 will have a better chance of surviving1 and thus be naturally selected4 ,from the strong principle of inheritance any selected variety will tend to propagate its new and modified form4 7,origin of ,species1 ,intro47 ,this statement of the doctrine of the survival of the fittest1 suggesting a glimpse at the great pageant of nature from the remotest times1 shows how the organisms existing at this moment are the descendants of the victors in the world's greatest battles4 ,the struggles for life1 always keen and persistent1 shared in by every individual organism1 both animal and vegetable1 are the instigators of all progress in the natural world4 ,they are nature's means for the attainment of beauty1 usefulness1 and perfection4 ,the ,darwinian theory was based upon the observed facts that members of any given species are not alike1 while their offspring may differ in numerous ways from their parents4 ,the data furnished by zology1 botany1 physiology1 and other sciences supply overwhelming evidence that the present species of animals and plants have arisen through the modification from various causes of many pre-existing species4 ,the organisms with which we are familiar owe their characteristics to the accumulation of a long series of changes similar to those that we may see that they are still undergoing4 ,the methods pursued in studying variation in species1 and its important accompaniment1 heredity1 consists in comparison1 statistical examinations1 cultural experiments1 and crossbreeding4 ,evolution is the process of differentiation accompanying the operations of nature4 ,all the great naturalists before ,darwin's time noted facts indicating this universal differentiation1 but it required the particularly wide sweep of ,darwin's mind to phrase and demonstrate it4 ,the law of origin by evolution1 as ,herbert ,spencer showed1 is not confined to the method of bringing into existence new species of animals and plants4 ,the stars1 planets1 the geological strata and earth contours and forms1 human institutions1 social customs1 and practically everything in nature are obedient to it4 ,much research work in evolution has been done since ,darwin stated his theory1 but the basic principle of the survival of the fittest remains untouched by criticism4 ,some of his views respecting minor details of selection and the effects of various factors have been modified or enlarged1 and many new evolutionary forces have been discovered4 ,it has also been found that a single cause is usually followed by more than one effect4 ,weissmann has drawn attention to the importance of adaptations4 ,most organic beings are usually closely fitted for the conditions under which their lives are spent4 ,the principal parts of every animal and plant1 and all the points in which one species differs from a nearly related species1 have been shown to have arisen on account of their usefulness to the creatures possessing them4 ,as natural selection is always progressive1 it follows that no adaptation is ever perfect4 ,there is always progress from the useful to the more useful--a continual striving for greater beauty of form and color and higher efficiency4 ,works on evolution furnish an abundance of interesting evidence showing how adaptation works4 ,a single instance may be cited here4 ,one of the ,mexican yucca plants common in our ,southern ,states is pollinated by a moth of the ,pronuba family4 ,this moth is adapted for its work by several special organs including a special ovipositor and peculiar maxillary tentacles which are not found in other moths4 ,the female moth collects pollen with these tentacles from several yucca flowers1 rolls it into a ball and kneads it into a pellet4 ,when the pellet is ready the moth seeks an unvisited flower and1 after depositing a few of her own eggs in the ovary1 she climbs the style and forces the pollen pellet into the stigma4 ,this is the way the yucca is pollinated and fertilized4 ,two important purposes are served by this arrangement3 a species of plant and a species of moth1 together with those dependent upon them1 are enabled to survive by this moth's activities4 ,there are many known cases of similar cooperative adaptation to living conditions4 ,quetelet1 in #ahde1 followed by ,francis ,goltin and ,karl ,pearson1 have applied statistical methods in dealing with evolutionary problems1 and a new science called biometry has been developed4 ,this science has yielded much important data regarding the effects of inherited characteristics4 ,the studies of variations in plants by mutations1 made by the ,dutch botanist ,de ,vries1 have opened up wide fields of study regarding the causes of variation4 ,he has shown that increased bulk or better coloration may result from improved nutrition and more light1 and that such improved characteristics may be inherited4 ,a law of ancestral heredity has been worked out for men by biometricians1 and this has been confirmed by the experiments of ,professor ,johannsen1 of ,copenhagen1 on self-fertilizing beans1 and by ,jennings on protozoa4 ,this hypothesis suggests that every ancestor of a particular man or woman contributes its quota to the heritable qualities displayed by that individual4 ,the average amount of resemblance between an individual and any of his particular ancestors is capable of being numerically expressed4 ,the experiments and conclusions of ,gregor ,mendel 7#ahbb-ahhb7 tend to oppose the law of ancestral heredity1 but it is believed that any exceptional cases may be explained by the operation of special conditions4 ,karl ,pearson has shown by the analyses of numerous statistical records of ,englishmen that by artificial selection any selected characteristic1 such as facial contour or stature1 can be changed within a few generations4 ,but when the character has been changed about #ij per cent within a short time another method must be employed1 because the original one then becomes less efficient4 ,individuals in any given population who differ in size from the mean of the population give rise to offspring which differs from that mean value in the same direction but to a smaller extent4 ,the same law applies to the color of the hair or to intelligence or constitution4 ,selection will always produce a change in the average character of a population taken as a whole4 ,but selection within a pure line1 or one which shows only normal variability about a mean or type value1 does not produce marked changes4 ,the usual selection within any particular population consists in the partial separation of extreme types4 ,the personal characteristics of any ancestor do not influence his descendants4 ,only the typical characteristics are handed down4 ,these and many other facts developed by investigations in biometry should be of value in regulating immigration1 so as to guard against degenerative influences1 and they have greatly increased the efficiency of farming by showing how to improve farm stocks and crops so as to yield larger returns4 ,farmers have been more ready than politicians to avail of their advantages4 ,we note how the speed of racing and trotting horses1 and the milking capacity of cows1 have been improved by the past century1 but we are doing little to reform national health and efficiency4 ,mutation is the name given to the process of origination of a new species or character accomplished by a single step or by a series of steps4 ,bateson1 in #ahid1 showed that symmetry is a characteristic common to all organisms4 ,this may affect the whole or parts of an organ4 ,major symmetry involves the whole organism and minor symmetry only an organ or part4 ,there are meristic variations1 involving the symmetrical pattern1 and substantive variations involving changes in the constitution or substance of the organism4 ,red-flowering plants1 for example1 may yield offspring bearing white flowers4 ,substantive variations are often discontinuous1 or accidental1 and are infrequent4 ,organic bodies are built up of a number of cells4 ,the living material of cells is protoplasm formed out of many elements1 of which carbon1 oxygen1 hydrogen1 nitrogen1 and sulphur are the more important4 ,new cells arise from bipartition of existing cells4 ,therefore by following back the history of any animal or plant we will arrive at a stage when its ancestors had only one cell4 ,every animal or plant which is propagated sexually actually starts as a cell and develops through its main evolutionary changes in the embryonic state4 ,cells are liable to all the evolutionary changes that the organism as a whole is subject to4 ,studies of embryology have shown that the fusion of biparental reproductive cells results in the formation of a complete new individual which1 at the time of the fusing of the two conjugating cells1 called gametes1 or germ cells1 inherits the characteristics of each parent and its ancestors4 ,the determination of the sex of the cell1 plant1 or animal1 depends upon the presence of extra male or female sex-chromosomes1 or sex-determinant fibers of the cell nucleus4 ,certain animals and plants transmit male characteristics to the female descendants1 while the female transmits her characteristics to the male descendants4 ,there are many variations of this kind4 ,these strange movements in heredity are explained by the laws governing chromosomes and idio-chromosomes and elementary cells4 ,according to the germ plasm theory of inheritance1 the separate parts of living organisms are assumed to be represented by separate material particles in the germ cells4 ,in the ,mendelian theory each cell is assumed to contain a large number of ids1 or complete sets of sex determinants1 half the total being derived from each parent4 ,this permits the germ cells to contain a certain number of ids from each parent4 ,studies of these subjects show that the great harmonies of the natural world are manifested in form1 number1 pattern1 and color1 which we find to be basically simple and1 when studied systematically1 they appear quite clearly1 so as to be capable of being described and expressed as laws4 ,the study of the agencies under social control which may improve1 or impair1 the racial qualities of future generations1 either physically1 socially1 or mentally1 is called the science of eugenics4 ,this new science is another outgrowth of the revolution in intellectual development originating with the publication of ,darwin's theory4 ,sir ,francis ,galton was the pioneer worker1 and he has been followed by ,pearson1 ,yule1 ,lombroso 7#ahcf-aiji71 and others4 ,eugenic studies1 confirmed by those of genetics and biometry1 show that the human race1 which is the masterpiece of ,nature's evolutionary processes1 is capable of much further development through the careful guiding of the very forces used in evolving man to his present state4 ,man can be improved by selection and education to greater beauty1 clearer intellect1 larger stature1 sounder character1 and better physique4 ,the measure of what man has done is a good criterion of what he is capable of doing under the guidance and encouragement of science4 ,genetics1 the study of the hereditary phenomena of organisms1 is based upon the law of inheritance discovered by ,mendel in #ahfe4 ,this law relates to the inheritance of certain definite characters called allelomorphs4 ,these characters are found to group themselves in pairs which exhibit more or less antagonistic qualities4 ,a knowledge of these characteristics is necessary to conduct selective breeding experiments scientifically4 ,it is found that when two similar germ cells1 each bearing the same new combination of allelomorphs1 meet in fertilization1 they result in the development of a new zygotic combination of a pure type which breeds true4 ,this accounts for the establishment of new species4 ,when1 on the other hand1 the coupling is unequal1 or only partial1 there will be irregularities in the characters of the offspring and no new species is likely to develop4 ,immense value is attached to this law by naturalists working in all fields4 ,the three new sciences of eugenics1 genetics1 and biometry have prepared the way for a regeneration of humanity through breeding in the desirable and breeding out the undesirable4 ,,chapter ,,xiii ,,chemical ,,and ,,botanical ,,theories ,the ,world ,war served to demonstrate the degree of perfection which has been attained in chemistry4 ,the wonderful high explosives used1 the poisonous gases1 the lubricating and motor oils and a multitude of valuable chemicals employed for military and naval purposes1 many of which were developed at short notice1 showed the modern chemist's command of his science4 ,yet chemistry is a new science4 ,practically it began with ,robert ,boyle1 in ,england1 in #affa4 ,boyle conducted experiments on the rarefaction of air and the nature of gases1 and in his book1 ,the ,sceptical ,chemist1 he made this remarkable statement3 ,i am apt to think that men will never be able to explain the phenomena of nature1 while they endeavor to deduce them only from the presence and proportions of such or such ingredients1 and consider such ingredients or elements as bodies in a state of rest2 whereas1 indeed1 the greatest part of the affections of matter1 and consequently of the phenomena of nature1 seem to depend upon the motion and contrivance of the small parts of bodies4 ,thus ,boyle anticipated the chemical theories of matter developed in the nineteenth century4 ,lavoisier1 about #aggg1 advancing from the quantitative study of one chemical change to another was able to describe many processes1 and to distinguish between an element and a compound4 ,he cast aside all the alchemical formul and expressed the results of his experiments in fractions and proportions4 ,j4 ,b4 ,richter between #agia and #ahjb made a series of experiments by which he secured the weights of various bases neutralized by constant weights of several acids1 and the weights of several acids neutralized by constant weights of several bases4 ,he found that the composition of chemical compounds is constant1 as had been assumed by ,lavoisier and ,boyle4 ,dalton described the atomic constitution of gases in #ahjh1 and sketched the law of multiple proportions in chemical combinations and described binary1 ternary and quaternary combinations4 ,prussic acid was investigated by ,gay-,lussac in #ahae1 when he isolated cyanogen and found that although it is a compound it plays the part of an element with hydrogen and the metals4 ,berzelius also found that ammonium possessed all the properties of an alkali metal4 ,ten years after the above discoveries were made1 ,faraday prepared a compound of carbon and hydrogen from liquefied coal gas which led to the general study of isomerism and the great discoveries of the organic radicals with their important combinations4 ,when isomeric combinations were studied by ,jacob ,berzelius 7#aggi-ahdh71 he was led to devise a means of expressing organic reactions4 ,he wrote to ,whler and ,liebig a letter outlining his new method in which he said3 ,from the moment when one has learned to recognize with certainty the existence of ternary atoms of the first order which enter compounds after the manner of simple substances1 it will be a great relief in the expression of the language of formul to denote each radical by its own symbol1 whereby the idea of composition it is desired to express will be placed clearly before the eye of the reader4 ,illustration3 ,photo1 ,fifth ,avenue ,hospital ,,room ,,in ,,which ,,infected ,,articles ,,are ,,sterilized ,illustration3 ,,modern ,,operating ,,room ,,in ,a ,,paris ,,hospital4 ,,it ,,is ,,fitted ,,with ,a ,,glass ,,dome ,,and ,,radio ,,microphones ,,for ,,the ,,use ,,of ,,students ,,and ,,doctors ,,who ,,wish ,,to ,,watch ,,the ,,operations ,,and ,,hear ,,distinctly ,,the ,,comments ,,of ,,the ,,surgeons ,an example of this method of expressing reactions was given in the case of the action of chlorine on benzoic acid4 ,he wrote ,b,o for benzoic acid1 ,b,,cl for chlorbenzol and ,b ,,nh for benzamide4 ,with certain simple improvements made subsequently by ,gmelin1 the method devised by ,berzelius was generally adopted and is in use to-day4 ,the numerous investigations now being made with the object of discovering the various combinations of the elements led to many improvements in chemical analyses4 ,when we read ,berzelius' accounts of his analyses they seem to have been written only yesterday4 ,he and his contemporaries developed analytical and synthetic methods to almost the efficiency that we see to-day4 ,we also owe to ,berzelius a table of the elements showing their electrical qualities1 an electrochemical theory1 identifying chemical affinity with electric attraction1 and a new nomenclature1 besides a vast amount of descriptive chemistry4 ,the discovery of the specific heats of various solid elements by ,dulong and ,petit in #ahai1 and ,mitscherlich's finding of the isomorphic phenomena in #ahah1 resulted in the publication of a new atomic weight table in #ahbf by ,berzelius4 ,the experiments made in isomorphism by ,mitscherlich led him to discover dimorphism and study crystallography4 ,he used his knowledge of crystal measurement extensively and developed synthetic chemistry and the laws of crystallization4 ,thompson1 ,prout1 and ,wollaston were working on problems in ,england similar to those examined in ,sweden by ,berzelius and ,mitscherlich4 ,molecules were discriminated from atoms in #ahbf by ,jean ,baptiste ,dumas and ,faraday discovered his law of electrochemical action in #ahcd4 ,organic chemistry originated in ,manchester1 ,england1 when ,dalton read his paper before the ,manchester ,philosophic ,society in #ahjc on the theory of atomic weights4 ,this paper led ,gay-,lussac1 ,thenard1 ,berthollet1 de ,saussure and others to study organic analyses as devised by ,dalton4 ,gay-,lussac and ,thenard greatly improved ,dalton's methods and in #ahbd1 as shown by ,chevreul's work on fats and greases1 organic analyses had been brought to high perfection4 ,the phenomena of substitution in hydrocarbon compounds like the petroleum oils were studied by ,laurent who proposed a theory of basic nuclei4 ,c,h being the nucleus of the naphthalene group and ,c,h that of the ethylene group1 derived nuclei can be obtained from these by substitution and hydrogen and other elements acting on derived nuclei from numerous hydrocarbon series4 ,the homology of the hydrocarbons was discovered by ,gerhardt in #ahdd while he was investigating the alcohols4 ,wurtz's work on the ammonia compounds1 ,williamson's on the ethers1 ,hoffmann's on anilines1 ,graham's and ,liebig's on the citrates1 and ,frankland's1 ,kolbe's and ,kekul's work on other compounds raised organic chemistry to such a high plane that industrial chemists were able to use their theoretical conclusions and build a great number of important industries upon organic principles4 ,lothar ,meyer1 in #ahfh1 and ,mendeleff1 in #ahfi1 published atomic weights showing improvements in the theories of valency and the interrelationship of atomic weights4 ,mendeleff was able to predict from the vacant positions in his table the discovery of important new elements4 ,a number of these elements have since been discovered4 ,the aniline dye industries have grown out of the discoveries of many chemists4 ,the basic work was done by ,faraday1 ,laurent1 and ,runge1 who isolated valuable hydrocarbons from coal gas tar4 ,hoffmann discovered aniline and ,perkin obtained mauve in #ahef by the oxidation of aniline with chromic acid4 ,it was this and subsequent discoveries by ,perkin which gave the greatest impetus to synthetic dyes4 ,the solubility of a dye was improved by increasing its acidity 7sulphonation7 or by increasing its alkalinity 7alkylation74 ,similar dyes are now made by the same methods from many common aromatic substances4 ,the chemistry of explosives was developed by ,van ,helmont1 ,debus1 ,bunsen1 ,abel1 ,nobel1 and1 others4 ,fulminates were used for detonators by ,ure in #ahca1 picrates were employed as explosives by ,fontaine and ,abel2 nitrocellulose 7guncotton7 discovered by ,braconnot in #ahcb and used as an explosive by ,schnbein in #ahdf1 and nitroglycerine was produced by ,sobrero in #ahdg4 ,smokeless powders made from guncotton1 dynamite1 and gelatine were introduced by ,nobel in #ahij4 ,pasteur showed1 in #ahdh1 that when the double sodium ammonium racemate was crystallized1 two kinds of crystals separated from the solution4 ,when one set of crystals was dissolved in water the solution rotated a beam of polarized light to the left1 while the aqueous solution of the other crystals rotated the light to the right4 ,these crystals thus revealed their geometrical properties with perfect light while in solution in water4 ,pasteur noted that optical activity of this kind is the expression of some form of molecular asymmetry4 ,le ,bel in #ahgd also pointed out that optical activity is an expression of the asymmetry of the chemical molecule and showed that all carbon compounds which are optically active contain a carbon atom combined with four different atoms1 or groups4 ,van't ,hoff showed in #ahge that there were definite relations between the arrangements of tetrahedral carbon atoms and polarization phenomena and established the theory of such atoms4 ,willard ,gibbs1 of ,yale1 discovered what is known as the phase rule1 which shows1 by thermodynamic methods1 how the conditions of chemical equilibria can be systematically grouped4 ,van't ,hoff1 ,pfeffer1 and others noticed that when two solutions are brought together1 if one is more concentrated than the other1 diffusion begins in the concentrated and extends to the weaker solution4 ,this shows a talent force in concentrated solutions which is now known as osmotic pressure4 ,van't ,hoff and ,arrhenius showed that for comparable concentrations the osmotic pressure of a solution is exactly equal to the pressure of a gas4 ,these discoveries led to a brilliant series of investigations into electrolytic chemistry4 ,the theory of electrolytic dissociation advanced by ,ostwald shows that the molecules of electrolytes in aqueous solutions are broken down into electrically charged parts called ions4 ,in very dilute solutions the dissociation of strong acids1 bases1 and salts is practically complete as was suggested by ,williamson in #ahea4 ,catalysis1 or reaction brought about by agents which do not enter into the chemical changes1 was discovered by ,berzelius4 ,ostwald investigated and developed catalytic reactions which are now extensively employed in industry1 particularly in refining oils and in the fixation of nitrogen4 ,hot platinum1 for example1 is used to act catalytically in causing sulphur dioxide and oxygen to combine and form the basis of sulphuric acid1 sulphur trioxide4 ,one of the most important applications of catalysis to industry is the ,haber process for securing nitrogen from the air4 ,when air and hydrogen are compressed and heated to a high temperature in the presence of a catalyzer such as metallic uranium or iron carbide1 the nitrogen and hydrogen combine and form ammonia4 ,the experiments of ,sir ,william ,crookes on vacuum tubes subjected to electrical impulses led the way to the discovery of radioactivity1 and investigations of radium have revolutionized our conceptions of the nature and properties of matter4 ,the discovery of helium1 argon1 the niton emanation from radium and other elements by ,ramsay1 ,collie1 ,soddy1 and others will be referred to later4 ,carl ,linnus1 who is called the father of modern botany1 established the genera and species of plants upon philosophical principles4 ,he established a binomial nomenclature and formulated modern descriptive methods4 ,thus he prepared the way for the systematic works of ,de ,jussieu and ,de ,candolle4 ,de ,candolle1 in #ahai1 published a new method of classification based upon morphological characters4 ,he defined and illustrated the doctrine of the symmetry of plant organs and asserted that a natural classification must be based on a plan of symmetry4 ,the relationships between the endosperm and embryo were shown in #ahaj by ,robert ,brown in his monograph on the ,australian ,proteace4 ,the morphological nature of seed reserves was described by him4 ,he also discovered the functions of the cell nucleus and founded cytology4 ,he showed that the oscillation of minute particles in the fluids of plants when viewed under high microscopic powers1 known as the ,brownian movement1 is due to purely physical causes4 ,schultze1 ,unger1 and others1 working on suggestions previously made by ,knight1 ,robert ,brown1 and ,hooke1 discovered the rle of protoplasm in plant cells4 ,alexander ,braun and ,de ,bary correlated the movements of protoplasm with the locomotory movements of free zogonidia and the amboid movements of ,mycetozoa4 ,these investigations directed research to further studies of the structure and constitution of protoplasm and helped develop the cellular theory4 ,the ,alg were studied and classified by ,naegeli1 ,unger1 ,von ,mohl1 ,haustein1 and others in #ahdg-ahej4 ,the vascular cryptogams were studied by ,hofmeister4 ,he found that the alternation of a sexual with an asexual generation is common to all plants of the mosses1 vascular cryptogams1 and gymnosperms1 as well as among angiosperms4 ,hofmeister's work led to appreciation of the fact that a natural system of plant classification must be based1 not on balancing the values of the morphological parts of fruits and flowers1 but on the anatomy of the real and concealed reproductive organs4 ,fossil botany1 or paleophytology1 was founded1 in #ahbh1 by ,adolphe ,brongniart4 ,witham1 ,goeppert1 ,unger1 ,corda1 and others helped to advance this science4 ,the publication of ,darwin's ,origin of ,species in #ahei found the various botanical sciences already well worked out by numerous capable experts4 ,a huge amount of data and descriptive matter had been assembled and botany1 like the other sciences1 was ready to be quickened by the ,darwinian theories4 ,the idea of a progressive evolution in plants had been suspected by many botanists1 but the genius of ,darwin developed it4 ,living plants were pictured as a multitude of units competing for food1 light1 air1 and room for growth1 and struggling against unfavorable environments4 ,the classification of tissues was begun1 and the phenomena of absorption of water and salts1 the ascent of sap1 the absorption of minerals and nitrogen1 and metabolism and growth were elucidated4 ,investigations were made into the nature and functions of chlorophyll and other plant substances4 ,these studies resulted in suggesting means for improving crops by artificial selection1 as shown in the work of ,luther ,burbank4 ,,chapter ,,xiv ,,geology1 ,,metallurgy1 ,,and ,,meteorology ,geology is essentially a nineteenth century product4 ,fossils1 minerals1 rocks1 and rock strata had attracted more or less attention from the earliest times4 ,the ,egyptians1 ,greeks1 and ,romans had books dealing with such subjects1 and ,greek philosophers1 like ,aristotle1 lectured upon them4 ,but it was only in the last century that geology was placed upon a scientific basis and began to make progress4 ,the reformation was begun by ,cuvier's work on paleontology1 the chemical and physical discoveries of the eighteenth century1 and the works of ,hooke1 ,boyle1 ,buffon1 ,linnus1 and others4 ,the special technique required in geographical research could not be developed until the biological1 anatomical1 botanical1 and physical sciences had been established on a scientific plane4 ,that is why geology remained for so many centuries undeveloped1 and then rapidly advanced during the nineteenth century4 ,its preparation was long and involved1 while its fruition was rapid and brilliant4 ,william ,smith 7#agfi-ahci71 called the father of ,english geology1 was a mining surveyor engaged in making colliery and farm surveys in ,oxfordshire and the west of ,england4 ,his professional work led him to study the coal outcrops1 and in #agic he mapped the inclined coal deposits in ,somersetshire4 ,the numerous rock strata accompanying the coal beds contained fossils which he found could be used to identify the beds in that field with others in northern counties4 ,he published an account of this manner of using type fossils for identifying fossiliferous rock formations in #agii1 and in #ahae issued his geological map of ,england1 ,wales1 and southern ,scotland4 ,this map showed the advantages that scientific geology and mineralogy offered to industry and caused scientists all over ,europe to study geological phenomena and make sketch maps of local geology4 ,a work on paleontology1 dealing with the fossils of the ,old ,red ,sandstone deposits1 published in ,england by ,hugh ,miller 7#ahjb-ahef71 which had an enormous popularity and has been described as the most fascinating book ever written on a geological subject1 followed ,smith's ,strata ,identified by ,organized ,fossils4 ,a large amount of mapping resulted from the issuing of these two works4 ,these maps called for detailed descriptions1 and these in turn resulted in the accumulation of many interesting data which1 when collected1 and systematized1 led to many important discoveries4 ,while these authors were preparing their books1 ,werner1 ,de ,luc1 ,de ,saussure1 ,lamarck1 and others were working out paleontological problems1 ,rom de l',isle1 ,brongniart1 ,hay1 d',aubuisson1 and others were building up the science of mineralogy4 ,the ,theory of the ,earth1 of ,dr4 ,james ,hutton 7#agbf-agig71 was published in #aghe1 and in an enlarged form in #agie4 ,this book described the metamorphoses of sand into sandstones1 quartzites1 schists1 and other rock formations2 the work of floods and lava floods2 the sculpturing powers of streams1 rains1 and winds1 etc4 ,he indicated the effects of the alternate sinking and raising of strata through earth shrinkings and volcanic phenomena1 and taught that purely physical causes can be found for every geological effect4 ,playfair's ,illustrations of the ,huttonian ,theory of the ,earth augmented the teachings of ,hutton's book1 while works by ,jameson1 ,kirwan1 ,bou1 ,sir ,james ,hall1 ,daubre1 ,st4 ,claire-,deville1 ,buckland1 ,sedgwick1 ,bakewell1 ,breislak1 ,maclure1 and others rapidly appeared sustaining the ,huttonian1 or the ,wernerean theories of geological deposition4 ,the work of ,james ,sowerby 7#ageg-ahbb71 entitled ,the ,mineral ,conchology of ,great ,britain and that of ,james de ,carle ,sowerby 7#agha-ahga71 published between #ahab and #ahde1 marked the establishment of paleontology as a science4 ,both father and son were well-trained naturalists and artists1 and1 like ,william ,smith1 reproduced the fossils and their containing rocks to scale and in natural colors4 ,these works greatly simplified the labors of field geologists in identifying rock strata and type fossils4 ,in ,germany geology was worked out by ,baron von ,schlotheim 7#agfd-ahhb71 ,goldfuss 7#aghb-ahdh71 and ,count ,munster 7#aggf-ahdd74 ,brocchi 7#aggb-ahbf7 described ,italian fossil strata4 ,the ,geological ,classification of ,rocks1 of ,mac,culloch1 marked the separation of petrology as a science from descriptive geology4 ,mac,culloch noted that the ancient granites and granite schists are among the oldest rock forms4 ,von ,humboldt1 ,murchison1 ,lyell1 ,de la ,beche1 ,von ,buch1 ,elie de ,beaumont1 ,holley1 ,geikie1 ,bonney1 ,wollaston1 ,scrope and ,daubeny were among the pioneer geologists in ,europe1 while ,james ,dwight ,dana 7#ahah-ahie71 ,e4 ,s4 ,dana1 ,conrad1 ,hitchcock1 ,warren1 ,lesley1 ,fremont1 and others published descriptive geological accounts in the ,united ,states4 ,references to the geology and minerals of ,new ,mexico were made in ,humboldt's ,new ,spain4 ,greenhow's work on ,oregon and ,california1 published in #ahde1 and ,lewis and ,clark's reports added much to our knowledge of ,american topography and geology4 ,these reports were followed by those of ,stanton1 ,clarence ,king1 ,hague1 ,emmons1 ,custer1 ,powell1 ,davis1 ,gilbert1 ,agassiz1 and others which dealt with various phases of ,american geology1 paleontology1 glaciation1 and mineralogy1 and prepared the way for the publication of the valuable works of ,dana1 ,williams1 ,iddings1 ,washington1 ,pirsson1 ,clarke1 ,grabau1 ,brush1 and others4 ,the treatment of geological problems from the viewpoint of present causes was begun after the publication of ,lyell's ,principles of ,geology 7#ahcj-ahcc74 ,earlier geologists were aware of the fact that many of the rock formations had been derived from other consolidation of sand and mud beds and by other actions which may be studied in operation to-day4 ,but the systematic manner in which ,lyell treated the whole field of geology made such an impression upon geologists that the publication of his great work marked a new era in the science4 ,de la ,beche1 ,buckland1 ,geikie1 ,bonney1 and other geologists in ,england2 ,dana1 and a number of scientists in the ,united ,states ,geological ,survey1 in ,america2 ,vogt and ,naumann1 in ,germany2 ,studer in ,switzerland2 ,stopanni1 in ,italy1 and many specialists in other countries took up the work of ,lyell1 and at present practically every important geological factor is known and the effects of its operations have been described4 ,the succession of life in geological periods is studied under paleontology4 ,this science developed at the same time as systematic and descriptive geology4 ,many great naturalists have contributed to it4 ,agassiz1 ,hall1 ,dawson1 ,walcott1 ,marsh1 and others in the ,united ,states and ,canada2 ,owen1 ,prestwich1 and others in ,england2 and numerous writers in ,europe have published valuable monographs on various phases of fossil and strata-graphical geology4 ,paleontology1 by fixing the succession of animal and vegetable eras1 has served as a basis for measuring time1 revealing the antiquity of man and of the principal mammals1 as well as showing changes in climate1 and in land and sea areas4 ,the application of geology to many industries called forth another branch of the science known as economic geology4 ,this deals with the origin and geographical distribution of the useful minerals1 the derivation of underground waters and petroleum1 and the changes undergone by soils4 ,the first important impetus to economic geology was given by the publication of ,whitney's ,metallic ,wealth of the ,united ,states in #ahed1 ,von ,cotta's work on ore deposits in #ahei1 and the economic references in the textbooks of the leading ,european and ,american geologists4 ,the recent work of ,bonney1 ,groddeck1 ,de ,launay1 ,phillips1 ,prosepny1 ,van ,hise1 ,emmons1 ,le ,conte1 ,lindgren1 and others has greatly advanced the interest and usefulness of the science4 ,these writers carried out an extended series of investigations on the depth temperature and physical and chemical condition of the earth's crust4 ,chemical analyses of rocks and soils were made and the changes wrought by physical and chemical forces were noted4 ,on these were based theories as to the formation of rocks1 soils1 minerals1 and ore deposits4 ,the erosive properties of soil water were found to be limited to a depth not exceeding #bj1jjj feet1 although hydrostatic water bodies are rarely found as low as half that distance1 the rise in temperature precluding their existence4 ,the work of these men revealed the part played by vulcanism in rock changes1 and the effects produced through hot solutions and magmatic intrusions4 ,various systems of classification of minerals and ore deposits were developed4 ,richard ,beck's1 ,the ,nature of ,ore ,deposits 7#aijj71 and ,lindgren's ,mineral ,deposits 7#aiai71 are works which have contributed to the systematizing of economic geology from the mineral standpoint1 and the establishment of epochs of metal generation4 ,the ore deposits of the ,united ,states have been described in the monographs of the ,united ,states ,geological ,survey1 and by ,kemp1 ,spurr1 ,grabau and other writers4 ,this branch of geology emphasizes the strong tendency to concentration shown by mineral elements4 ,all climatic forces are found to aid this work4 ,underground waters1 both flowing and stationary1 are powerful assistants4 ,other phases of economic geology have been developed in studies of subterranean waters1 microscopical petrology and mineralogy1 the chemical analyses of rocks1 etc4 ,among the leaders in this work have been ,pirsson1 ,emmons1 ,iddings1 ,washington1 ,van ,hise1 ,clarke1 and others4 ,the enormous metallurgical industries of to-day are all dependent upon scientific principles chiefly discovered and applied in the nineteenth century4 ,metallurgists in the previous century knew that by adding certain metals to molten steel it could be hardened4 ,a method of this kind was published by ,raumur in #agbb4 ,tool points1 he showed1 could be hardened if the steel when red hot was forced into solid tin1 lead1 copper1 silver or gold1 thus producing an alloy stronger and harder than the pure steel4 ,a series of calorimetric researches on metallic alloys1 carried on by ,bergman1 led to the discovery that steel differs from iron merely in the carbon contents4 ,clouet1 in #agih1 followed this by an experiment in which he melted up a little crucible iron with a diamond and obtained a mass of steel4 ,this created a sensation and led to many other experiments on the metallurgy of cast and wrought iron and steel4 ,thomas ,young1 in #ahjb-g1 studied the mechanical properties of iron and steel and developed the theory of the modulus of elasticity4 ,a patent was issued to the ,rev4 ,robert ,stirling1 in #ahag1 for a regenerative iron smelting furnace4 ,the next year ,samuel ,baldwin ,rogers substituted iron bottoms for sand bottoms in puddling furnaces4 ,faraday and ,stodart produced the first alloy of nickel and steel in #ahbj1 and in #ahbb ,faraday showed that there is a fundamental chemical difference between hard and soft steel4 ,the first patent for a hot blast for iron furnaces was granted to ,james ,beaumont ,neilson in #ahbh4 ,all these discoveries led to important improvements in iron making4 ,the steam hammer was patented by ,nasmyth in #ahdb1 and between #ahdc and #ahdh ,thomas ,andrews conducted valuable investigations into the heat of combination4 ,the ground was now prepared for one of the greatest of metallurgical inventions--the conversion of pig iron into steel by an air blast in a ,bessemer converter4 ,this invention not only vastly extended the use of steel1 but drew attention to the valuable oxidizing effects of a hot air blast and in that way induced many important improvements in the metallurgy of copper1 lead1 and zinc4 ,siemens1 ,whitworth1 ,bell1 ,graham1 ,percy1 ,richards1 ,martin1 ,thomas1 ,holley1 ,hewitt1 ,fritz1 ,howe1 ,jones1 and others made further important improvements in the metallurgy of iron and steel in the ,united ,states and ,europe4 ,one of the early ,american iron smelters was built by ,governor ,keith1 in #agbf1 in ,new ,castle ,county1 ,delaware4 ,a rolling mill and forge were subsequently built at ,wilmington4 ,the first ,american smelted iron was shipped to ,england from smelters in ,maryland and ,virginia in #agah4 ,the ,bessemer steel process was introduced into the ,united ,states by ,abram ,hewitt at the ,troy smelter1 ,new ,york1 in #ahfe4 ,from these beginnings the iron industries of the ,united ,states have grown so that they now produce more than two-fifths of the world's annual supplies4 ,the alloys of iron and steel have now attained importance and a new science known as metallography has developed4 ,professor ,arnold1 of ,sheffield1 ,sherard ,cowper-,coles1 ,roberts-,austen1 ,sorby1 ,tschermak1 ,tschernoff1 ,wst1 and ,ziegler have been active promoters of this branch of metallurgy1 and a closely related one dealing with the effects of the heat treatment of metals4 ,developments in the iron industries led to others in the metallurgy of copper1 lead1 and zinc4 ,the application of the blast furnace to copper1 lead1 and zinc smelting was chiefly made in ,america4 ,one of the early furnaces was built in ,leadville1 ,colorado1 in #ahgg4 ,from that time1 pyritic smelting has been chiefly developed by ,american metallurgists4 ,the metallurgy of lead1 copper1 and zinc has reached a similar high plane to that attained by iron and steel4 ,the metallurgy of gold and silver began to improve after the discovery of the ,californian deposits in #ahdh4 ,the stamper battery and amalgamation processes were improved2 when sulphide ores were encountered1 chlorination processes were developed4 ,subsequently1 in response to demand for a cheaper chemical solvent for low-grade ores1 the cyanide and bromide processes were devised4 ,the application of the electric furnace to metallurgy greatly increased the scope of metallurgists' methods4 ,pichon1 in #ahec1 described a small arc furnace with which he was experimenting1 and in #ahgh ,sir ,william ,siemens built a furnace for reducing iron ores4 ,moissan made numerous tests of furnaces and smelting methods in the nineties and did much to develop commercial electric smelting4 ,faure1 ,cowles1 ,borchers1 ,de ,chalmont1 ,girod1 ,heroult1 and others invented furnaces1 smelting methods1 and metallurgical processes4 ,the aluminum1 carborundum1 acetylene1 and other important industries are developments from the electrometallurgy of iron and copper4 ,zinc1 copper1 nickel1 silver1 gold1 and platinum plating and the electrodepositing of copper in the form of tubes by the ,elmore process are dependent upon the principles of electrometallurgy as is the electrorefining of metals4

,,oscillating ,,audion ,illustration3 ,,automobile ,,with ,,radio ,,equipment ,,for ,,listening ,,in ,,en ,,tour ,the physical phenomena of the earth's atmosphere are studied under the science of meteorology4 ,the art of weather forecasting is as old almost as mankind1 but only in recent years has it been placed upon a sound basis4 ,torricelli1 in #afdc1 invented the barometer2 ,boyle1 in #afhe1 developed it and applied it to measuring gas pressures4 ,the chemists of the eighteenth century1 ,boyle1 ,black1 ,rutherford1 ,priestley1 ,scheele1 ,lavoisier1 and ,cavendish1 all studied the chemistry of the atmosphere4 ,franklin1 in #agdi1 raised thermometers by kites to measure temperatures4 ,balloon ascents were made by ,jefferies and ,blanchard1 in #aghd1 for atmospheric observations4 ,soundings of the upper air by balloons1 kites1 and other apparatus have been conducted since the closing years of the nineteenth century4 ,,chapter ,,xv ,,medicine ,,and ,,pharmacy ,medicine was in a state of transition at the beginning of the nineteenth century4 ,the great scientific discoveries of the eighteenth century had carried people away to such an extent that they showed a tendency to exaggerate their bearings upon medicine4 ,the result was a wild diffusion of extravagant speculation and unsubstantial hypotheses4 ,one of the leading physicians of the eighteenth century1 who wielded broad influence throughout ,europe1 was ,herman ,boerhaave 7#affh-agch74 ,his work1 entitled ,aphorismi1 published in ,leyden1 #agji1 was immensely popular4 ,it was translated into all the ,european and several ,asiatic languages4 ,his reputation now depends upon his chemical discoveries and his medical teachings4 ,one of the most brilliant students of ,boerhaave's medical school was ,albrecht von ,haller 7#agjh-gg74 ,haller published many medical works and monographs4 ,his ,elements of ,human ,physiology1 7#agei-ff7 is the best known4 ,the function of bile in the digestion of fats1 the demonstration of ,glisson's hypothesis that irritability in an excised muscle is a specific property of all living tissues1 and several theories explaining the heart's activities1 were among his best contributions to medical science4 ,the discovery of the existence of lacteal and lymphatic vessels in birds1 reptiles1 and fish brought ,william ,hewson into prominence and secured him membership in the ,royal ,society4 ,he published his monograph on the coagulation of the blood in #agga4 ,william ,cumberland ,cruikshank 7#agde-ahjj7 investigated the surgery of the nerves1 the functioning of the ,fallopian tubes1 the physiology of absorption4 ,the electrical discoveries of ,galvani1 ,volta1 ,benjamin ,franklin1 ,henly and others caused much experimenting with the electric current in the treatment of muscular diseases4 ,the ,monros1 father1 son and grandson1 by their wonderful teaching abilities1 caused the medical teaching center of ,europe to be transferred from ,leyden to ,edinburgh in #agbj4 ,these men1 and many of their students1 did brilliant work in all branches of medicine4 ,the medical school which they so established in ,edinburgh ,university still maintains its great reputation4 ,the best anatomists of the eighteenth century were ,cheselden1 ,pott1 the ,monros1 the ,hunters1 ,desault1 and ,scarpa4 ,their work was largely topographical4 ,surgical anatomy started with the writings of ,joseph ,lieutaud 7#agjc-aghj71 ,albinus1 ,eisenmann1 ,soemmering1 ,mascagni1 ,sandifort1 and ,caldani4 ,the anatomical textbooks in use in the year #ahjj gave general accounts of the body's structure and included current theories of the functions of organs and their relationships to injuries and disease4 ,more than half of the chapters were occupied with morbid anatomy and the recital of cases4 ,the anatomy of the tissues and finer structures was neglected because the microscopes of the period were little better than simple lenses4 ,physiology was studied by all medical students1 but the science was so badly developed that it never stood alone4 ,for many years it formed a part of studies in anatomy4 ,early in the nineteenth century it began to expand1 and in #ahdf physiology was taught as a separate subject for the first time at ,guy's hospital1 ,london1 by ,sir ,william ,gull4 ,before that it was taught by the professors of midwifery4 ,it was the great developments made in chemistry and physics1 referred to in previous chapters1 that pushed physiology to the front as an important branch of medical science4 ,denman's ,introduction to the ,practice of ,midwifery1 the work of the greatest living authority at the time of its publication in #ahje1 shows that gynecology hardly existed at that time4 ,anesthetics and antiseptics1 together with the systematic employment of abdominal and bimanual palpation1 all were revolutionary discoveries of the nineteenth century1 unknown when ,denman presided over the obstetric department of the ,middlesex ,hospital4 ,when the nineteenth century opened1 medical men were unaware of the value of auscultation and percussion4 ,they were familiar with the symptoms of fevers and with diseases of the heart and chest1 but they had no means of determining differences between them4 ,textbooks of that time show that the now common forms of heart disease were known only from post-mortem inspections4 ,but they distinctly state that physicians were unable to determine1 in case of changes in stricture of the heart's valves1 what part was affected4 ,the seat of disease in heart and chest troubles could not be located4 ,parasitology was no better advanced4 ,books published as late as #ahaj indicated that parasites1 like hydatids1 threadworms1 etc41 were very puzzling phenomena to the physician4 ,the status of surgery throughout the eighteenth century was very low4 ,the best work was done in ,france and ,holland1 until ,cheselden1 the ,hunters1 the ,monros1 and ,abernethy established their schools in ,england and ,scotland4 ,german medical practitioners were barbers until after the army authorities formed the ,medico-,chirurgical ,ppinire in ,berlin in #aghe4 ,there were several good medical schools in the ,united ,states in #ahjj including those of the ,king's ,college1 ,new ,york1 and of the ,harvard1 ,dartmouth1 and ,philadelphia ,colleges1 and the ,university of ,pennsylvania4 ,there were also numerous medical societies4 ,european medical and surgical textbooks were used like those of ,cheselden1 ,monro1 ,haller1 ,boerhaave and ,sydenham4 ,medical practice was on the same plane in ,america as in ,europe4 ,there were many patent remedies used1 but the authorities recognized the importance of regulating the practice of medicine4 ,regulation acts were passed in ,new ,york ,city in #agfj1 ,new ,jersey in #aggb1 and a general quarantine act was enacted by ,congress in #agii4 ,the modernization of medicine was brought about to a large extent by the publication of the ,conservation of ,energy by ,helmholtz1 in #ahdg1 and ,darwin's ,origin of ,species1 in #ahei4 ,these books cleared away completely the myths and legends which had surrounded medicine at earlier periods1 and taught medical students the strict need of proceeding entirely upon scientific grounds precisely as chemists1 physicists1 engineers1 and others were already doing with wonderful success4 ,darwin's biological teachings appealed very strongly to medical men and influenced all their activities4 ,virchow's ,cellular ,pathology1 published in #aheh1 ,huxley's textbooks on ,physiology 7#ahff7 and on ,vertebrate and ,invertebrate ,anatomy 7#ahga-gg7 ,haeckel's ,general ,morphology 7#ahff71 and numerous medical encyclopedias and textbooks on practice and special diseases were the result of the new scientific spirit4 ,new medical associations were formed and these promoted discussions1 the reporting of observations1 and the publication of innumerable monographs4 ,medical journals and magazines of a high character did fine educational work4 ,the investigations on fermentation and putrefaction made in ,france by ,pasteur caused ,joseph ,lister1 professor of surgery at ,glasgow ,university1 to reflect upon the great mortality witnessed daily in the hospitals from pymia1 erysipelas1 tetanus1 septicemia1 gangrene1 and other similar diseases4 ,he observed that in spite of his great care to maintain scrupulous cleanliness in treating wounds1 #de per cent of his surgical cases were mortal4 ,pasteur's dictum that putrefaction is a micro-organic phenomenon1 caused ,lister to experiment with the view of preventing the development of microorganisms in wounds4 ,beginning with weak solutions of zinc chloride and zinc sulphite1 he accidentally tried carbolic acid1 securing surprising results1 and two years later1 in #ahfg1 he published his monograph on antiseptic surgery which instantly became world-famous4 ,lister1 instead of being carried away by the celebrity he attained1 turned his attention to the scientific development of his important discovery4 ,he investigated lactic-acid fermentation1 the relation of bacteria to flesh inflammations and to the best methods of treating wounds antiseptically4 ,lister1 however1 was not the first to employ antiseptics in the treatment of wounds1 and his great contribution to medical practice was due to the systematic manner in which he experimented4 ,he was not a brilliant surgeon1 but a deliberate and careful one whose chief desire was to have the patient recover4 ,his whole surgical career was guided by this principle which proved so successful that before his death the whole medical profession saluted him as master1 and when he died1 rejoiced that his remains were entombed in ,westminster ,abbey4 ,theodor ,billroth was one of ,lister's greatest disciples4 ,he introduced ,lister's methods into continental surgery and through their use improved the treatment of wounds and opened up new fields in the surgery of the alimentary tract4 ,he was the first to make a resection of the esophagus and pylorus and to excise the larynx4 ,mikulicz-,rodecki1 a ,pole1 was ,billroth's chief assistant4 ,he was also a pioneer in ,lister's practice4 ,specializing on the surgery of the alimentary organs1 he promoted antiseptic methods and introduced the modern modes of exploring the esophagus and stomach4 ,he was also a master in the treatment of diseases of the mouth4 ,felix ,guyon applied ,lister's system to surgical treatment of the genitourinary ailments1 and became a leader in this class of surgery4 ,bernard ,naunyn1 a well-known ,german writer on surgery1 became a leading authority on diabetes and diseases of the liver and pancreas4 ,jean ,martin ,charcot made the ,salptrire ,hospital1 ,paris1 the greatest of the world's neurological clinics4 ,he was also a great authority on diseases of the biliary passages and kidneys4 ,sir ,james ,paget1 ,sir ,jonathan ,hutchinson1 ,sir ,william ,gull1 ,jenner1 ,wilks1 ,spencer ,wells1 and ,clifford ,allbutt1 besides doing much by their writings to advance the practice of medicine1 all closely allied themselves with large hospitals1 giving as much attention to the hospitals as to the treatment of disease4 ,modern hospitals are largely due to their pioneering work4 ,louis ,pasteur's studies in fermentation led to the discovery of lactic-acid bacteria and this was the starting point for a number of revolutionary discoveries in bacterial diseases4 ,infectious diseases were placed in new categories by his work4 ,the etiology of traumatic infectious diseases was advanced by the researches of ,robert ,koch 7#ahdc-aiaj74 ,his work in discovering the cholera vibrio1 the microorganisms of ,oriental ophthalmia and his researches on the nature and treatment of tuberculosis1 made his name known everywhere4 ,his isolation of the tuberculosis germ in #ahhb1 and that of ,asiatic cholera in #ahhd1 were leading steps toward the discovery of a great number of disease germs4 ,fevers1 like typhus1 typhoid1 yellow fever1 and malaria1 a few generations ago1 took a great annual toll of lives4 ,the work of the men mentioned above1 ,lister1 ,pasteur1 ,koch1 and the ,french physiologist1 ,claude ,bernard1 gave medical men the means of curbing the ravages of these diseases so that to-day they are incidental annoyances rather than human scourges4 ,the germ of typhoid fever was discovered in #ahhj by ,eberth4 ,the cocci of pneumonia were isolated by ,frankel in #ahhf4 ,modern surgery has been greatly facilitated by the employment of numerous anesthetics1 chemicals which possess the power of inducing local or general insensibility4 ,soporific drugs have been used in surgical operations since the remotest antiquity1 but modern practices in the employment of anesthetics followed the discoveries of ,faraday in #ahah4 ,he described the properties of nitrous oxide1 or ether and other gases in that year and suggested their use in medicine4 ,john ,godman 7#ahbb71 ,james ,jackson 7#ahcc71 and ,drs4 ,wood and ,bache 7#ahcd7 were among ,american medical men who made use of ,faraday's suggestions4 ,dr4 ,horace ,wells1 a dentist at ,hartford1 ,connecticut1 used ether in #ahdd4 ,two years later ,w4 ,t4 ,morton1 a dentist in ,boston1 employed it successfully4 ,chloroform was described as a useful anesthetic by ,dr4 ,flourens1 of ,paris1 in #ahdg1 the year in which ,sir ,james ,simpson introduced ether as an anesthetic in obstetric practice4 ,mesmer introduced hypnosis into medical practice about #aggg1 and in #aghd ,benjamin ,franklin reported favorably on the medical value of what he called magnetic sleep4 ,alexandre ,bertrand1 about #ahca1 described the nature of hypnosis and in #ahda ,james ,braid employed it in his ,english medical practice4 ,the employment of hypnosis has not become general1 although it is recognized that in certain nervous troubles there is a field for it4 ,among other ,american medical men who advanced their science in the past were ,james ,marion ,sims 7#ahac-ahhc7 and ,thomas ,emmet1 who acquired wide fame for successful methods of operating in obstetric diseases4 ,william ,beaumont 7#aghe-ahec7 investigated the offices of the gastric juice and devised treatment for digestive troubles4 ,john ,shaw ,billings served his profession by compiling1 with the assistance of ,robert ,fletcher1 an ,index ,catalogue of the ,surgeon ,general's library1 ,washington4 ,pharmacology is as old as medicine4 ,the medicinal qualities of herbs1 roots1 and gums were known to primitive man4 ,there have been herbalists and druggists in all important communities at all times4 ,scientific pharmacology1 however1 is just as new as modern medicine4 ,cordus published a pharmacopia1 which listed drugs in use in #aece4 ,since that time many such works have appeared4 ,the second of the ,monros of ,edinburgh ,university ,medical ,school1 ,magendie1 and ,claude ,bernard placed pharmacy upon a scientific basis4 ,they followed scientific methods used by ,fontana in ,florence in #agfe in studying the effects of snake poisons4 ,pareira's ,elements of ,materia ,medica was the leading textbook in #ahdb4 ,this work gave very brief accounts of the physiological effects of drugs4 ,the physiological values were not properly appreciated until about twenty years later4 ,drugs are now scientifically classified and prepared1 the full resources of science being used in their manufacture4 ,american chemists have invented machinery and methods of preparing new drugs4 ,citrate of magnesia was invented by ,henry ,blair1 of ,philadelphia4 ,many other valuable remedies came from his laboratory1 including sirup of phosphates4 ,,chapter ,,xvi ,,electricity ,,and ,,radioactivities ,among the most marvelous scientific developments of the nineteenth century those in the electrical field claim universal attention4 ,it was only as recently as #ahdd that ,morse introduced electric telegraphy4 ,the telephone was introduced by ,alexander ,graham ,bell in #ahgf and ,edison built one of his early dynamos in #ahgh and in #ahgi made his first high resistance incandescent lamp for parallel operation4 ,the first ,edison power and lighting station was opened at #beg ,pearl ,street1 ,new ,york ,city1 in #ahhb4 ,although electrical phenomena were understood in a general way thousands of years ago1 they were not studied and applied to practical purposes until the sixteenth century when ,william ,gilbert carried out his classical experiments in the reign of ,queen ,elizabeth4 ,the ,leyden jar was discovered in the early half of the eighteenth century4 ,from experiments carried out with these jars a great number of important inventions were derived and our knowledge of electricity was for many years dependent upon researches of this kind4 ,benjamin ,franklin in experimenting with the ,leyden jar found that its electrical discharges were similar to those of lightning and he subsequently discovered that the inner part of the jar1 when charged with a frictional current1 was positively electrical while the outer portion was negative4 ,the voltaic pile was invented in #agif as a result of ,galvani's experiments in physiological electricity and ,sir ,humphry ,davy exhibited the first practical electrical lamp before the ,royal ,society in #ahji4 ,the dynamo was1 in substance1 invented by ,faraday1 and described by him before the ,royal ,society in #ahca4 ,this was1 perhaps1 the greatest of all electrical triumphs because it gave engineers a practical means of generating and using electrical currents of any desired dimensions4 ,bunsen in #ahdj devised a means for making carbon rods for arc lamps1 and ,edison made practical carbon incandescent lamp filaments in #ahgi4 ,faraday's invention promoted all of these lighting discoveries4 ,the engine-driven electric dynamo was made a practical machine in #ahgj and thenceforward became the source of power of a great multitude of secondary machines1 such as electric street cars1 marine engines1 power plants1 and forging hammers4 ,a new and profitable field was opened for the use of electricity by the invention of the electric furnace4 ,sir ,humphry ,davy produced his electric arc in #ahjh and was greatly impressed with its fusing properties4 ,he melted many metals with the arc and found that it fused platinum just as easily as an ordinary tallow candle melts beeswax4 ,the electric furnace1 which is now extensively used in chemical and metallurgical works1 is simply a large electric arc provided with means for containing the heat4 ,furnaces lined with carbon are now heated to over #d1jjj degrees centigrade4 ,when the electrical manufacture of aluminum on a large scale was started at ,niagara1 ,dr4 ,edward ,acheson1 who was impressed by the industrial needs of cheap abrasives1 accidentally discovered that by heating a piece of porcelain to a high temperature in an electric furnace and bringing it in contact with pure carbon1 the carbon was rendered very hard4 ,in #ahia he carried on experiments with high currents and a mixture of ground coke and sand4 ,he found a method of fusing these so that the oxygen of the sand passed off with carbon in the form of carbonic acid gas1 and the reduced metallic silicon combined with an equal atomic weight of carbon and produced a new body which he named carborundum4 ,the success met with in making carborundum led to the devising of a method of manufacturing artificial graphite in the electric furnace4 ,a soft1 non-coalescing graphite was made in #aijf4 ,this is extensively used in lubricating heavy machinery4 ,dr4 ,acheson produced the first chemically pure artificial carbon in his electric furnace in #aiaa4 ,by using pressure during consolidation this carbon may eventually be converted into diamonds4 ,another valuable product of the electric furnace1 acetylene gas1 was discovered in ,dublin by ,edmund ,davy in #ahcf4 ,subsequently numerous chemists discovered means for making carbides4 ,t4 ,sterry ,hunt1 an ,american chemist1 observed in #ahhf that oxides of the alkaline metals and of calcium1 magnesium1 aluminum1 silicon1 and boron could be reduced in the electric furnace in the presence of carbon and could be alloyed with other metals4 ,he also found that silicon and acetylene could be made that way4 ,t4 ,l4 ,wilson1 a ,canadian engineer1 in attempting to make aluminum bronze in an electric furnace1 devised an experiment for reducing lime with carbon4 ,he found that this produced calcium carbide and secured a patent for the invention in #ahib4 ,variations of this process are now used for manufacturing nitrogen and nitrates from atmospheric nitrogen4 ,wireless developments have resulted from the work of many separate investigators4 ,k4 ,a4 ,steenheil in #ahch used the earth return in live telegraphy and suggested the possibility of wireless telegraphy4 ,joseph ,henry produced the first high-frequency oscillations in ,america in #ahdj4 ,lord ,kelvin in #ahec enunciated the mathematical principles governing uncoupled electrical oscillatory circuits4 ,joseph ,heyworth patented a wireless telegraphic process in #ahfb4 ,clark ,maxwell in #ahfg predicted the existence of electromagnetic radiations and these were demonstrated by ,hertz in #ahhg4 ,hughes discovered the phenomena of the coherer and ,branby used ,hughes's coherer for wireless wave detection in #ahib4 ,a4 ,e4 ,dolbear secured ,united ,states patents for a system of wireless telegraphy using aerials in #ahhf4 ,sir ,oliver ,lodge described his wireless system before the ,royal ,society in #ahid and in the same year ,popoff issued descriptions of his wireless system4 ,wireless telegraphy became commercially practicable in #ahig when ,g4 ,marconi secured the promotion of the ,wireless ,telegraph and ,signal ,company in ,england4 ,marconi succeeded in turning to commercial account a long series of brilliant discoveries in electricity1 and this success has led to numerous kindred discoveries4 ,de ,forest's three-electrode thermionic detector1 known as an ,audion1 invented in #aijg and improved in #aiaa by ,lieben and ,reiss1 in #aiac by ,meisser and in #aiad by ,langmuir1 opened up great possibilities for sound transmission by wireless telephony4 ,the electric deposition and refining of metals have been referred to in previous chapters4 ,many industries are based upon these4 ,niepce produced commercially successful photographs in #ahch4 ,earlier1 in #ahbd1 he had etched plates for printing and in that year published his photo-engraving of ,cardinal d',amboise4 ,fox ,talbot patented a mixture of gelatine and bichromate of potash to take the place of the bitumen used by ,niepce as a plate coating4 ,gillot found in #ahgb that ,fox ,talbot's method of making intaglio plates could also be used for making relief blocks4 ,in #ahhe-ahhf1 ,f4 ,e4 ,ives sealed two single-line screws together and made a new fine cross-line screen1 which resulted in the development of the half-tone process4 ,ives at this time also developed the three-color photo-engraving process4 ,photography and photo-engraving are so widely used and are so intimately connected with our civilization that few people now realize that the great industries based upon them are the results of a few scientific discoveries of a couple of ,american and ,european scientists made only a generation or two ago4 ,illustration3 ,,gifts ,,for ,,tutankhamen

,amenophis ,,iv74 ,the original is now in the ,berlin ,museum4 ,chemists had long recognized the fact that certain chemicals like preparations of zinc1 fluorine1 and phosphorus were phosphorescent4 ,it was found early in the eighties that ,welsbach gas mantles1 when placed on a photographic plate and exposed in a dark room for two weeks1 made a fine picture4 ,invisible rays in the mantle imprint its image4 ,rntgen1 in #ahie1 discovered what are now known as the ,x-rays4 ,this discovery was the result of experiments begun in #ahei by ,plucker to ascertain the cause of fluorescence in light glass1 and ,sir ,william ,crookes1 between #ahgi and #ahhe1 carried out beautiful experiments on fluorescence4 ,these were the immediate pioneers of the discovery of the cathode rays and the other great radio discoveries of recent years4 ,crookes1 remembering ,faraday's suggestions concerning a fourth state of matter1 expressed the opinion1 in #ahhe1 that the matter constituting cathode rays is neither solid1 gaseous1 or liquid1 but in a fourth state which transcends the gaseous condition4 ,perren found in #ahie that the rays carried electrically negative charges and ,sir ,j4 ,j4 ,thomson noticed that their velocities are appreciably less than the speed of light4 ,owing1 however1 to their great momentum1 hardly anything can long endure their impacts4 ,they fuse platinum and make diamonds buckle up into coke4 ,electrons1 which constitute the cathode rays1 were originally studied in ,crookes vacuum tubes1 though they are now found to pervade the universe4 ,larmor in #ahig proposed an electronic theory of magnetism4 ,henri ,becquerel was the first to discover radioactivity4 ,he made radiographs from uranium salts in #ahif4 ,m4 and ,madame ,curie undertook the investigation of uranium and found that among the minerals occurring in pitchblende1 or uranium ore1 bismuth and barium showed radioactive properties1 whereas when these metals are found in their ordinary ores they are not radioactive4 ,this discovery led to the finding of two new metals1 polonium and radium4 ,radium is now obtained by fractional distillation of solutions obtained from ,american and ,australian pitchblende4 ,helium1 one of the lightest substances known1 was discovered in #ahie by ,sir ,william ,ramsay1 and liquefied1 at a temperature #c degrees above absolute zero1 or -#bgj degrees centigrade1 by ,onnes in #aijh4 ,helium appears to be one of the ultimate products of the disintegration of all radioactive elements4 ,some of the most interesting discoveries about radioactivity are very recent4 ,radium prepared from uranium in #aiae was found in #aiai to have increased proportionately to the square of the time interval4 ,the amount of radium in some preparations was found to have increased ten times in four years4 ,the old idea of the constant fluxation of matter was thus shown to have been based upon a scientific truth4 ,,chapter ,,xvii ,,science ,,in ,,the ,,twentieth ,,century ,it is obvious that we are now in a great period of transition4 ,scientific discoveries came so quickly at the end of the last century that a recasting and readjusting of scientific conceptions had to be undertaken4 ,this process was in progress when the ,world ,war began4 ,the world-wide disturbance led to temporary scientific infertility except in such directions as served the purposes of war4 ,but therein science became allied more closely than ever before with certain branches of industry1 and the cooperation thus established has been recognized in all civilized countries as of the utmost value to the future progress of mankind4 ,the philosophic thought of each era generally develops in harmony with social and intellectual conditions4 ,the philosophical doctrines of the leading writers may1 therefore1 be taken as representative of the spirit of their age4 ,when ,darwin in the middle of the last century published his doctrines of evolution1 of the struggle for existence and the influences of living conditions upon survival of species1 philosophy turned away from the utilitarianism and tolerance of ,hamilton1 ,hume1 and ,mill and the positivism of the ,french to the synthetic evolutionism of ,herbert ,spencer4 ,one of the basic teachings of ,spencer was the relativity of knowledge4 ,the process of thinking involves relation1 difference1 and likeness4 ,this is merely relationing4 ,therefore no thought can ever express more than relations4 ,the primary act of thought through which we discover likeness and difference underlies all our knowledge4 ,a reaction against this new empiricism began in #ahih1 when ,william ,james published his ,philosophical ,conceptions and ,practical ,results4 ,this work popularized the philosophy of pragmatism which denies the absoluteness or ultimateness of the traditional antithesis between theory and practice and relies for its justification upon the fact that everything which we think about1 and do1 must first be willed4 ,reality consists in pure experience quite independent of thought4 ,bergson developed this philosophy of practicalism further and taught that knowledge of reality comes through intuition and that life is merely intuitive knowledge4 ,intuition1 is deeper than scientific reason because it feels1 and links us with1 the eternal processes of nature4 ,philosophic thought is now temporarily influenced by the revival of an old principle known as the principle of relativity4 ,the popular name for this is the ,einstein theory1 because in #aije ,albert ,einstein1 working on some theories developed by ,lorentz and ,fitzgerald1 published his first principle of relativity which suggested that the velocity of light is constant1 however the position of an observer may vary and that space and time are variable4 ,in #aiag ,einstein enlarged this idea in order to include all the laws of nature4 ,space and time are treated as just mental concepts4 ,they lack the concreteness of matter1 but they compose the framing of the universe and give it form and continuity4 ,consequently we see so much of them that we attribute reality to them4 ,the theory of relativity suggests that time is not continuous4 ,there is no identity of instants at different places4 ,the present instant really does not extend beyond this immediate point4 ,at other points there are instants older1 younger1 and contemporaneous with this instant4 ,they are1 however1 quite distinct from this one4 ,in order for an instant to be simultaneous it would be necessary that it should occur at the same point4 ,an object or event gains its substance and form from activities of our minds4 ,any meaning or significance that an object or event has is also derived from our minds4 ,the reality of the universe is an activity1 or series of activities1 which are manifested in life and mind4 ,the relativity of space is illustrated by an example given by ,professor ,henri ,poincar4 ,assume that ,i meet you in ,wall ,street1 ,new ,york1 and say1 ,i will meet you here again at this time to-morrow4 ,you promise to do so4 ,but you could not keep such a promise except with regard to position on the surface of the earth1 because between now and to-morrow the earth will have moved over an enormous distance carrying ,wall ,street and a great mass of other things with it4 ,the sun also will have moved away the stars1 carrying the earth with it4 ,another interesting mental picture is drawn by ,professor ,herbert ,wildon ,carr to illustrate the philosophical meaning of the principle of relativity4 ,suppose that on a very frosty morning we were to see a watery vapor in the air we breathe condense into a little cloud and after floating around a while gradually disappear and become reabsorbed in the atmosphere4 ,assume that at the moment of this reabsorption we should undergo an instantaneous transformation of all our proportions so that our new dimensions become infinitesimal in comparison with our former state4 ,do you think that we would recognize the fact that we had changed8 ,the theory of relativity declares that we would not know what had happened1 because with the alteration in proportions the ratios would remain constant4 ,the change would express itself in the new dimensions of objects around us4 ,the little globules of water composing the little cloud would now appear like stars and planets occupying immense areas in distant spaces1 far apart from each other1 and all undergoing a slow age-long evolution4 ,such a change would be signalized as a new time and a new space4 ,yet the principle of relativity does not appear to our physical senses to represent a truth of nature4 ,it is noteworthy that the principle of relativity is usually invoked when conditions are unstable1 when thought is confused1 and when a period of readjustment is in progress4 ,thus the ,einstein theory may be representative of present-day harmonies1 but yet may prove1 in the future1 to have been merely a passing philosophic mood4 ,bagehot1 a shrewd observer1 writing in #ahfh about the changes wrought by ,darwin's evolutionary theory1 said3 ,there is scarcely a department of science or art which is the same1 or at all the same1 as it was fifty years ago4 ,a new world of inventions has grown up around us which we cannot help seeing2 a new world of ideas is in the air1 and affects us though we do not see it4 ,those were very true words more than half a century ago1 yet they serve to describe present conditions6 ,,general ,,index ,a1 vowel sound1 record of1 iv1 #bcd ,aard-vark1 xii1 #bha-b ,abacus1 or calculating machines1 xv1 #ahc-d1 xvi1 #fa ,abalones1 xii1 #ga ,abbe1 ,prof4 ,cleveland1 i1
