biology, study of living things and their vital processes. The field deals with all the physicochemical aspects of life. As a result of the modern tendency to unify scientific knowledge and investigation, however, there has been an overlapping of the field of biology with other scientific disciplines. Modern principles of other sciences—chemistry and physics, for example—are integrated with those of biology in such areas as biochemistry and biophysics.

A few years ago the world was suddenly astounded by hearing of an experiment of a most novel and daring nature, altogether unprecedented in the annals of science. In accordance with the Cambridge men's note, the cannon intended to discharge the projectile was to be planted in some country not further than 28° north or south from the equator, so that it might be aimed vertically at the Moon in the zenith. The bullet was to be animated with an initial velocity of 12,000 yards to the second. It was to be fired off on the night of December 1st, at thirteen minutes and twenty seconds before eleven o'clock, precisely. Four days afterwards it was to hit the Moon, at the very moment that she reached her perigee, that is to say, her nearest point to the Earth, about 228,000 miles distant. The leading members of the Club, namely President Barbican, Secretary Marston, Major Elphinstone and General Morgan, forming the executive committee, held several meetings to discuss the shape and material of the bullet, the nature and position of the cannon, and the quantity and quality of the powder. These questions settled, Barbican, aided by Murphy, the Chief Engineer of the Cold Spring Iron Works, selected a spot in Florida, near the 27th degree north latitude, called Stony Hill, where after the performance of many wonderful feats in mining engineering, the Columbiad was successfully cast. Things had reached this state when an incident occurred which excited the general interest a hundred fold.

During the Federal war in the United States a new and very influential club was established in the city of Baltimore, Maryland. It is well known with what energy the military instinct was developed amongst that nation of shipowners, shopkeepers, and mechanics. Mere tradesmen jumped their counters to become extempore captains, colonels, and generals without having passed the Military School at West Point; they soon rivalled their colleagues of the old continent, and, like them, gained victories by dint of lavishing bullets, millions, and men. But where Americans singularly surpassed Europeans was in the science of ballistics, or of throwing massive weapons by the use of an engine; not that their arms attained a higher degree of perfection, but they were of unusual dimensions, and consequently of hitherto unknown ranges. The English, French, and Prussians have nothing to learn about flank, running, enfilading, or point blank firing; but their cannon, howitzers, and mortars are mere pocket pistols compared with the formidable engines of American artillery. This fact ought to astonish no one. The Yankees, the first mechanicians in the world, are born engineers, just as Italians are musicians and Germans meta-physicians.

To cement together the detached fragments of a subject, never yet treated as a whole; to harmonize the true portions of discordant theories, by supplying the links of thought necessary to connect them, and by disentangling them from the errors with which they are always more or less interwoven; must necessarily require a considerable amount of original speculation. To other originality than this, the present work lays no claim. In the existing state of the cultivation of the sciences, there would be a very strong presumption against any one who should imagine that he had effected a revolution in the theory of the investigation of truth, or added any fundamentally new process to the practice of it. The improvement which remains to be effected in the methods of philosophizing (and the author believes that they have much need of improvement) can only consist in performing, more systematically and accurately, operations with which, at least in their elementary form, the human intellect in some one or other of its employments is already familiar.

Principles of Geology sought to explain the geological state of the modern Earth by considering the long-term effects of observable natural phenomena. Written with clarity and a dazzling intellectual passion, it is both a seminal work of modern geology and a compelling precursor to Darwinism, exploring the evidence for radical changes in climate and geography across the ages and speculating on the progressive development of life. A profound influence on Darwin, Principles of Geology also captured the imagination of contemporaries such as Melville, Emerson, Tennyson and George Eliot, transforming science with its depiction of the powerful forces that shape the natural world.

Charles Darwin's Descent of Man and Selection in Relation to Sex (1871) was the single most important European or American nineteenth-century statement that man is an integral part of the animal kingdom. As a work of science, Descent of Man mattered more, and was more coherent, rigorous, and in tune with scientific opinion than that of any of its predecessors in evolutionary theory. Darwin's "Man book" was a bigger immediate success than any of his other books, including the epochal Origin of Species (1859), and it was soon translated into numerous languages. Darwin wrote with engaging literary style, charming modesty, brilliant argument, and a discursive method of proof, making the book an exhilarating romp through the Earth's known natural history and our own history as well as contemporary scientists knew it.

The most obvious and the most distinctive features of the History of Civilisation, during the last fifty years, is the wonderful increase of industrial production by the application of machinery, the improvement of old technical processes and the invention of new ones, accompanied by an even more remarkable development of old and new means of locomotion and intercommunication. By this rapid and vast multiplication of the commodities and conveniences of existence, the general standard of comfort has been raised, the ravages of pestilence and famine have been checked, and the natural obstacles, which time and space offer to mutual intercourse, have been reduced in a manner, and to an extent, unknown to former ages.

They have imagined that the substitution of the adjective partial for universal will save the credit of the Pentateuch, and permit them after all without too many blushes to declare that the progress of modern science only strengthens the authority of Moses. It is raked alike by the old fashioned artillery of the churches and by the fatal weapons of precision with which the enfants perdus of the advancing forces of science are armed.

Which describes some of the things which were said by Charles Darwin. Author became known as 'Darwin's bulldog' because of his forceful and energetic support for Darwin's theory, especially at the notorious British Association meeting in Oxford in 1860. In fact, Huxley had some reservations about aspects of the theory, especially the element of gradual, continuous progress, but in public he was unwavering in his allegiance, saying in a letter to Darwin 'As for your doctrines I am prepared to go to the Stake if requisite'. In his 1870 essay collection Lay Sermons, Addresses, and Reviews, of which the title alone was designed to provoke controversy, he offers a variety of his writings, many of which were originally talks given to a range of audiences from learned societies to a working men's college, and including his own review of On the Origin of Species and a typically passionate response to two other reviews less favourable to Darwin.

In some brains it appears simply as an indentation of the margin of the hemisphere, but, in others, it extends for some distance more or less transversely outwards. I saw t in the right hemisphere of a female brain pass more than two inches outwards; and on another specimen, also the right hemisphere, it proceeded for four-tenths of an inch outwards, and then extended downwards, as far as the lower margin of the outer surface of the hemisphere. The imperfect definition of this fissure in the majority of human brains, as compared with its remarkable distinctness in the brain of most Quadrumana, is owing to the presence, in the former, of certain superficial, well marked, secondary convolutions which bridge it over and connect the parietal with the occipital lobe. The closer the first of these bridging gyri lies to the longitudinal fissure, the shorter is the external parieto-occipital fissure (loc. cit. p. 12).

The present book, as originally planned over seven years ago, was to be a simplified paraphrase or restatement of the principles embodied in Friedrich Ratzel’s Anthropo-Geographie. The German work is difficult reading even for Germans. To most English and American students of geographic environment it is a closed book, a treasure-house bolted and barred. Ratzel himself realized “that any English form could not be a literal translation, but must be adapted to the Anglo-Celtic and especially to the Anglo-American mind.” The writer undertook, with Ratzel’s approval, to make such an adapted restatement of the principles, with a view to making them pass current where they are now unknown. But the initial stages of the work revealed the necessity of a radical modification of the original plan.

This is mathematics book. Definition of one-to-one correspondence. Given any two sets of individuals, if it is possible to set up such a correspondence between the two sets that to any individual in one set corresponds one and only one individual in the other, then the two sets are said to be in one-to-one correspondence with each other. This notion, simple as it is, is of fundamental importance in all branches of science. The process of counting is nothing but a setting up of a one-to-one correspondence between the objects to be counted and certain words', one', two', 'three', etc., in the mind. Many savage peoples have discovered no better method of counting than by setting up a one-to-one correspondence between the objects to be counted and their fingers. The scientist who busies himself with naming and classifying the objects of nature is only setting up a one-to-one correspondence between the objects and certain words which serve, not as a means of counting the objects, but of listing them in a convenient way. Thus may be able to marshal and array his material in such a way as to bring to light relations that may exist between the objects themselves.

The history of science (see Krakatoa by Simon Winchester to learn more) and at the time when Percival Lowell's books on the canals of Mars were all the rage (and they still make interesting reading) Wallace was demonstrating scientifically there were no such things as canals or water running freely on the surface. Some (but not most) of his scientific assumptions are incorrect, but that's only because no one had been to Mars yet! This is an astounding little book, a fun read, and I enjoyed it thoroughly. Having said this, we're still undecided about life on Mars, but it's fascinating to watch the debate that took place over a century ago.

He conceived of the idea during the voyage of the Beagle while still in South America, before he had seen a coral island, and wrote it out as HMS Beagle crossed the Pacific Ocean, completing his draft by November 1835. At the time there was great scientific interest in the way that coral reefs formed, and Captain Robert FitzRoy's orders from the Admiraltyincluded the investigation of an atoll as an important scientific aim of the voyage. FitzRoy chose to survey the Keeling Islands in the Indian Ocean. The results supported Darwin's theory that the various types of coral reefs and atolls could be explained by uplift andsubsidence of vast areas of the Earth's crust under the oceans.

If a weasel crosses his path, he stops, and either throws three pebbles into the road, or, with the innate selfishness of fear, lets someone else go before him, and attract to himself the harm which may ensue.

This book essentially restated the argument of Life and Habit, stating that human variation, or ‘progress’, is due to ‘strokes of cunning – to a sense of need, and to study of the past and present which have given shrewd people a key with which to unlock the chambers of the future’. Butler believed that heredity was a mode of memory, and instinct was inherited memory. A world shaped by natural selection appeared to Butler to be ‘a world of chance and blindness’, which he simply could not accept, and he seized on what he saw as the wilful aspect of the Lamarckian mechanism of evolution to refute the apparent arbitrariness of the Darwinian vision.

The Effects of Cross and Self Fertilisation in the Vegetable Kingdom is a book on evolution in plants. In this book Darwin examines the effects of cross and self fertilisation of plants and provides experimental evidence for a hypothesis stated in his famed book of 1859, Origin of Species, that "in none [i. e. plant] [...] can self-fertilisation go on for perpetuity" (Origin, p. 101). He reports on experiments conducted on over 60 different species of plants, where he used controlled pollinations in order to produce self-fertilised and cross-fertilised descendants. Through growth experiments of this progeny, he concluded that self-fertilised progeny performed poorer in most species and for most traits measured. Thus he showed that inbreeding may have severe detrimental effects on progeny. While this idea was accepted by many, e. g. plant and animal breeders, Darwin's book provided overwhelming experimental support for this idea. This book has remained the starting point for the study of inbreeding and is cited in scientific papers to this effect to this day.

Everybody can see under the surface of the skin more delicate and softer looking tubes, which do not pulsate, which are of a bluish colour, and are termed the veins. And every person who has seen a recently killed animal opened knows that these two kinds of tubs, are connected with an apparatus which is placed in the chest, which apparatus, in recently killed animals, is still pulsating. And you know that in yourselves you can feel the pulsation of this organ, the heart, between the fifth and sixth ribs. This much of anatomy and physiology has been known from the oldest times, not only as a matter of curiosity, but because one of the great objects of men, from their earliest recorded existence, has been to kill one another, and it was a matter of considerable importance to know which was the best place for hitting an enemy.

It is a science book. Merchants occasionally go through a wholesome, though troublesome and not always satisfactory, process which they term 'taking stock'. After all the excitement of speculation, the pleasure of gain, and the pain of loss, the trader makes up his mind to face facts and to learn the exact quantity and quality of his solid and reliable possessions. The man of science does well sometimes to imitate this procedure; and, forgetting for the time the importance of his own small winnings, to re-examine the common stock in trade, so that he may make sure how far the stock of bullion in the cellar — on the faith of whose existence so much paper has been circulating — is really the solid gold of truth. The Anniversary Meeting of the Geological Society seems to be an occasion well suited for an undertaking of this kind — for an inquiry, in fact, into the nature and value of the present results of paleontological investigation; and the more so, as all those who have paid close attention to the late multitudinous discussions in which paleontology is implicated, must have felt the urgent necessity of some such scrutiny.

A philosophical study presented by the biologist author has been depicted in this book. There is no doubt that breeds may be made as different as species in many physiological characters. So with Dogs in their habits and instincts. It is a physiological peculiarity which leads the Greyhound to chase its prey by sight, —that enables the Beagle to track it by the scent, that impels the Terrier to its rat-hunting propensity, and that leads the Retriever to its habit of retrieving. These habits and instincts are all the results of physiological differences and peculiarities, which have been developed from a common stock, at least there is every reason to believe so.

Just in the same way as the gardener is able to multiply and reproduce the peculiarities and characters of particular plants by means of cuttings, so can the physiological experimentalist--as was shown by the Abbe Trembley many years ago--so can he do the same thing with many of the lower forms of animal life. M. de Trembley showed that you could take a polype and cut it into two, or four, or many pieces, mutilating it in all directions, and the pieces would still grow up and reproduce completely the original form of the animal.

The Descent of Man, and Selection in Relation to Sex is a book on evolutionary theory by English naturalist Charles Darwin, first published in 1871. It was Darwin's second book on evolutionary theory, following his 1859 work, On the Origin of Species, in which he explored the concept of natural selection. In The Descent of Man, Darwin applies evolutionary theory to human evolution, and details his theory of sexual selection, a form of biological adaptation distinct from, yet interconnected with, natural selection. The book discusses many related issues, including evolutionary psychology, evolutionary ethics, differences between human races, differences between sexes, the dominant role of women in choosing mating partners, and the relevance of the evolutionary theory to society.

The object of this book is to give an account of the science of Astronomy, as it is known at the present day, in a manner acceptable to the general reader. The Ptolemaic system persisted unshaken for about fourteen hundred years after the death of its author. Clearly men were flattered by the notion that their earth was the most important body in nature, that it stood still at the centre of the universe, and was the pivot upon which all things revolved.

It is very easy to gain a knowledge of the stars, if the learner sets to work in the proper manner. But he commonly meets with a difficulty at the outset of his task. He provides himself with a set of the ordinary star-maps, and then finds himself at a loss how to make use of them. Such maps tell him nothing of the position of the constellations on the sky. If he happen to recognize a constellation, then indeed his maps, if properly constructed, will tell him the names of the stars forming the constellation, and also he may be able to recognize a few of the neighboring constellations. But when he has done this he may meet with a new difficulty, even as respects this very constellation. For if he look for it again some months later, he will neither find it in its former place nor will it present the same aspect, —if indeed it happen to be above the horizon at all.

The book is the Proserpina, Volume 1 Studies of Wayside Flowers. It had written about variety of a favourite flower botanical garden and plant. Which said book was therefore undertaken, to put, if it might be, some elements of the science of botany into a form more tenable by ordinary human and childish faculties; or for I can scarcely say I have yet any tenure of it myself to make the paths of approach to it more pleasant. In fact, I only know, of it, the pleasant distant effects which it bears to simple eyes; and some pretty mists and mysteries.

The following Narrative is only a part of a voyage undertaken for the purpose of conveying the Bread-fruit Tree from the South Sea Islands to the West Indies. The manner in which this expedition miscarried, with the subsequent transactions and events, are here related. This part of the voyage is not first in the order of time, yet the circumstances are so distinct from that by which it was preceded, that it appears unnecessary to delay giving as much early information as possible concerning so extraordinary an event. The rest will be laid before the Public as soon as it can be got ready; and it is intended to publish it in such a manner, as, with the present Narrative, will make the account of the voyage compleat.

Our knowledge of the stars is based on their apparent attributes, obtained from the astronomical observations. The object of astronomy is to deduce here from the real or absolute attributes of the stars, which are their position in space, their movement, and their physical nature. The apparent attributes of the stars are studied by the aid of their radiation. The characteristics of this radiation may be described in different ways, according as the nature of the light is defined. (Undulatory theory, Emission theory) From the statistical point of view it will be convenient to consider the radiation as consisting of an emanation of small particles from the radiating body (the star). These particles are characterized by certain attributes, which may differ in degree from one particle to another. These attributes may be, for instance, the diameter and form of the particles, their mode of rotation, &c. By these attributes the optical and electrical properties of the radiation are to be explained. I shall not here attempt any such explanation, but shall confine myself to the property which the particles have of possessing a different mode of deviating from the rectilinear path as they pass from one medium to another. This deviation depends in some way on one or more attributes of the particles.

It is less than twenty—five years since the first cold Grapery was erected on the Hudson. Since the success of the culture of the delicious varieties of the exotic Grape has been demonstrated, the number of graperies has annually increased, and during the last ten years in a very rapid ratio, until they have become recognized as possible and desirable, among those even whose circumstances are moderate and limited. The newly—awakened interest in this branch of culture is manifested in the number and variety of books and other publications on this subject, the space devoted to it in the agricultural and horticultural journals, and especially in the increased number of graperies and vineyards which have been erected and planted in the last decade.

This is a science book. In this little volume the author gives but his own personal opinions upon the subjects discussed, and although the sentiments are expressed with an assurance born of conviction, yet he claims not infallibility. He has ever been unable to accept the usual explanations of the great physical forces; and the inadequacies of mooted theories have impelled him to efforts for more philosophical interpretations. If in his investigations he has been forced to strange and unusual conclusions, he has been actuated only by an honest desire to promote the advancement of science.

This work is designed to meet an existing want, viz. : a popular manual of Indian Mammalia. At present the only work of the kind is one which treats exclusively of the Peninsula of India, and which consequently omits the more interesting types found in Assam, Burmah, and Ceylon, as well as the countries bordering the British Indian Empire on the North. The geographical limits of the present work have been extended to all territories likely to be reached by the sportsman from India, thus greatly enlarging the field of its usefulness. The stiff formality of the compiled Natural Histories has been discarded, and the Author has endeavoured to present, in interesting conversational and often anecdotal style, the results of experience by himself and his personal friends; at the same time freely availing himself of all the known authorities upon the subject.

It is a science book. What is an Insect? When we remember that the insects alone comprise four-fifths of the animal kingdom, and that there are upwards of 200, 000 living species, it would seem a hopeless task to define what an insect is. But a common plan pervades the structure of them all. The bodies of all insects consist of a succession of rings, or segments, more or less hardened by the deposition of a chemical substance called chitine; these rings are arranged in three groups: the head, the thorax, or middle body, and the abdomen or hind body. In the six-footed insects, such as the bee, moth, beetle or dragon fly, four of these rings unite early in embryonic life to form the head; the thorax consists of three, as may be readily seen on slight examination, and the abdomen is composed either of ten or eleven rings. The body, then, seems divided or insected into three regions, whence the name insect.

This neat little book helped to popularize in England the new science of Astronomy, based in particular on Johann Kepler's Samnium and Galileo's discoveries with the telescope. Wilkins covers a surprising range of speculation on the nature of the Moon and the visible Lunar features, seen in tantalizing new detail with the new telescopes; Luna's possible inhabitants; and our potential means of travel thither. He amiably disputes with ancient and contemporary authors, drawing you into his thinking and making his conclusions seem quite reasonable.

This is a science book. There has been a spate of papers in the last several years analyzing sea level data (including tide gauge records) to look for acceleration, or its absence, or deceleration, or changes in acceleration … all in the vain hope that if one can show that sea level didn’t accelerate consistently throughout the 20th century then there’s no reason to believe it will accelerate in the 21st century (an idea which reveals complete ignorance of how qualified scientists estimate future sea level rise). Most such papers don’t say so explicitly, but the implication is dripping from their writings. And at least one of them did say so explicity — our old friend Dave Burton.

The portions of Scheele's Chemical Treatise on Air and Fire here reproduced in English are intended to form a companion volume to No. 7 of the Club Reprints, which contains Priestley's account of his discovery of oxygen. Not only have the claims of Scheele to the independent discovery of this gas never been disputed, but the valuable volume of Letters and Memoranda of Scheele, edited by order hold, which was published in 1892, places it beyond doubt that Scheele had obtained oxygen by more than one method at least as early as Priestley's first isolation of the gas, although his printed account of the discovery only appeared about two years after Priestley's. The evidence of this has been found in Scheele's laboratory notes, which are still preserved in the Royal Academy of Science in Stockholm.

"The violet is a plant without a stem whose height does not surpass one or two decimetres. Its leaves, radical, or carried on stolons, are sharp, or oval, crenulate, or heart-shape. Its stipules are oval-acuminate, or lanceolate. Its flowers, of sweet scent, of a dark violet or a reddish blue, are carried each on a slender peduncle, which bends down at the summit. Such is, for the botanist, the Violet, of which the poets would give assuredly another description".

We live in and form part of a system of things of immense diversity and perplexity, which we call Nature; and it is a matter of the deepest interest to all of us that we should form just conceptions of the constitution of that system and of its past history. With relation to this universe, man is, in extent, little more than a mathematical point; in duration but a fleeting shadow; he is a mere reed shaken in the winds of force. But, as Pascal long ago remarked, although a mere reed, he is a thinking reed; and in virtue of that wonderful capacity of thought, he has the power of framing for himself a symbolic conception of the universe, which, although doubtless highly imperfect and inadequate as a picture of the great whole, is yet sufficient to serve him as a chart for the guidance of his practical affairs.

Genre: Physics
Publish Date: 09 May 1931

Seller: Public Domain

It is an science book. In Cornu's elaborate memoir upon the determination of the velocity of light, several objections are made to the plan followed by Foucault, which will be considered in the latter part of this work. It may, however, be stated that the most important among these was that the deflection was too small to be measured with the required degree of accuracy. In order to employ this method, therefore, it was absolutely necessary that the deflection should be increased. In November, 1877, a modification of Foucault's arrangement suggested itself, by which this result could be accomplished. Between this time and March of the following year a number of preliminary experiments were performed in order to familiarize myself with the optical arrangements. The first experiment tried with the revolving mirror produced a deflection considerably greater than that obtained by Foucault. Thus far the only apparatus used was such as could be adapted from the apparatus in the laboratory of the Naval Academy. At the expense of dollar 10 a revolving mirror was made, which could execute 128 turns per second. The apparatus was installed in May, 1878, at the laboratory. The distance used was 500 feet, and the deflection was about twenty times that obtained by Foucault.
