The theory of probabilities, which Laplace described as common sense expressed in mathematical language, engaged his attention from its importance in physics and astronomy; and he applied his theory, not only to the ordinary problems of chances, but also to the inquiry into the causes of phenomena, vital statistics and future events.

Anatomy and the study of animal mechanism, animal physics and animal chemistry, all of which form part of a true zoology, were excluded from the usual definition of the word by the mere accident that the zoologist had his museum but not his garden of living specimens as the botanist had; 1 and, whilst the zoologist was thus deprived of the means of anatomical and physiological study - only later supplied by the method of preserving animal bodies in alcohol - the demands of medicine for a knowledge of the structure of the human animal brought into existence a separate and special study of human anatomy and physiology.

Thus he carried on the narrative of orderly development from the point at which it was left by Kant and Laplace - explaining by reference to the ascertained laws of physics and chemistry the configuration of the earth, its mountains and seas, its igneous and its stratified rocks, just as the astronomers had explained by those same laws the evolution of the sun and planets from diffused gaseous matter of high temperature.

Finally, it brought the simplest living matter or formless protoplasm before the mental vision as the startingpoint whence, by the operation of necessary mechanical causes, the highest forms have been evolved, and it rendered unavoidable the conclusion that this earliest living material was itself evolved by gradual processes, the result also of the known and recognized laws of physics and chemistry, from material which we should call not living.

Thus mysticism was finally banished from the domain of biology, and zoology became one of the physical sciences - the science which seeks to arrange and discuss the phenqmena of animal life and form, as the outcome of the operation of the laws of physics and chemistry.

General Tendencies Since Darwin Darwin may be said to have founded the science of bionomics, and at the same time to have given new stimulus and new direction to morphography, physiology, and plasmology, by uniting them as contributories to one common biological doctrine-the doctrine of organic evolution-itself but a part of the wider doctrine of universal evolution based on the laws of physics and chemistry.

Thus the reciprocity of the various organs, maintained throughout the divisions of physiological labour, is not merely a mechanical stability; it is also a mutual equilibration in functions incessantly at work on chemical levels, and on those levels of still higher complexity which seem to rise as far beyond chemistry as chemistry beyond physics.

A condition of this reform was the need of a preliminary training of the mind of the pupil in pure science, even in physics and chemistry; that is to say, before introduction into his professional studies.

His college career was distinguished, especially in mental philosophy, mathematics and physics.

This being so, not only were physics and mathematics impossible as sciences of necessary objective truth, but our apparent consciousness of a permanent self and object alike must be delusive.

In solar physics Huggins suggested a spectroscopic method for viewing the red prominences in daylight; and his experiments went far towards settling a much-disputed question regarding the solar distribution of calcium.

His voluminous writings in philology, natural history, physics and mathematics often accordingly have a good deal of the historical interest which attaches to pioneering work, however imperfectly performed; otherwise they now take rank as curiosities of literature merely.

This description, quoted from James Clerk Maxwell's article in the 9th edition of the Encyclopaedia Britannica, represents the historical position of the subject up till about 1860, when Maxwell began those constructive speculations in electrical theory, based on the influence of the physical views of Faraday and Lord Kelvin, which have in their subsequent development largely transformed theoretical physics into the science of the aether.

Wood, have been written largely on the basis of the general physics of the aether; while the Collected Papers of Lord Rayleigh should be accessible to all who desire a first-hand knowledge of the development of the optical side of the subject.

Here you find articles in the encyclopedia on topics related to physics.

It is presented as a historic document rather than as a current physics resource.

The first book teaches physics - in the wide sense which the Greeks assigned to this term - by means of extracts.

The introduction of the coefficients now called Laplace's, and their application, commence a new era in mathematical physics.

With all the important work he accomplished in physics - the enunciation of Boyle's law, the discovery of the part taken by air in the propagation of sound, and investigations on the expansive force of freezing water, on specific gravities and refractive powers, on crystals, on electricity, on colour, on hydrostatics, &c. - chemistry was his peculiar and favourite study.

After that date two more became known; the whole was familiar to John of Salisbury in 1159; while the Physics and Metaphysics came into notice about 1200.

There is hardly a branch of mathematical physics which is independent of these functions.

Though he did not altogether neglect logic and physics, he maintained that virtue is the only real aim of men.

He was educated at Upsala University, where in 1839 he became privat docent in physics.

Forster in 1887, which undertakes researches with reference to physics and mechanics, particularly as applied to technical industries.

The systems of Plato and Aristotle sought to adjust the rival claims of physics and ethics (although the supremacy of the latter was already acknowledged); but the popular religions were thrown overboard.

It might seem, indeed, that Stoicism indicates a falling off from Plato and Aristotle towards materialism, but the ethical dualism, which was the ruling tendency of the Stoa, could not long endure its materialistic physics, and took refuge in the metaphysical dualism of the Platonists.

Subsequently he became professor of physics at the Massachusetts Institute of Technology, and in 1876 he was appointed professor of astronomy and director of the Harvard College observatory.

He soon turned to the law, though for a time he was teacher of physics in a small local college; eventually went into politics, and did excellent work in 1847 as governor of his native state.

They naturally divide themselves into researches on sound, light and electricity, but extend into other branches of physics as well.

Thus he would enter in the Metaphysics a reference to the Physics, and in the Physics a reference to the Metaphysics, precisely because both were manuscripts in his library.

In order to refer back to the Physics, the De Coelo, and the De Generatione, this work begins by stating that the first causes of all nature and all natural motion, the stars ordered according to celestial motion and the bodily elements with their transmutations, and generation and corruption have all been discussed; and by adding that there remains to complete this investigation, what previous investigators called meteorology.

We have to remember the traces of his separate discourses, and his own double versions; and that, as in ancient times Simplicius, who had two versions of the Physics, Book vii., suggested that both were early versions of Book viii.

But at any rate the process was gradual; and Aristotle was advanced in metaphysics, mathematics, physics, dialectics, rhetoric and poetics, before he became the founder of logic.

But Zeller does not give enough weight either to the evidence of early composition contained in the Politics and Meteorology, or to the evidence of subsequent contemporaneous composition contained in the cross-references, e.g between the Physics and the Metaphysics.

Zeller tries to get over this difficulty of cross-reference by detaching Metaphysics, Book A, from the rest and placing it before the Physics.

The truth is that the Metaphysics both precedes and follows the Physics, because it had been all along occupying Aristotle ever since he began to differ from Plato's metaphysical views and indeed forms a kind of presupposed basis of his whole system.

It gives too much weight to Aristotle's logic, and too little to his metaphysics, on account of two prejudices of the commentators which led them to place both logic and physics before metaphysics.

Aristotle rightly used all the sciences of his day, and especially his own physics, as a basis of his metaphysics.

On the other hand, Aristotle entitles the science of all being " Primary Philosophy " (irpcori OeXoaoOla), and the science of physical being " Secondary Philosophy " (SEUTEpa 49eXoa041a), which suggests that his order is from Metaphysics to Physics, the reverse of his editor's order from Physics to Metaphysics.

It is, however, not the real order for studying the philosophy of Aristotle, because there is more Metaphysics in his Physics than Physics in his Metaphysics, and more Metaphysics in his Logic than Logic in his Metaphysics.

Such is the great mind of Aristotle manifested in the large map of learning, by which we have now to determine the order of his extant philosophical writings, with a view to studying them in their real order, which is neither chronological nor traditional, but philosophical and scientific. Turning over the pages of the Berlin edition, but passing over works which are perhaps spurious, we should put first and foremost speculative philosophy, and therein the primary philosophy of his Metaphysics (980 a 211093 b 29); then the secondary philosophy of his Physics, followed by his other physical works, general and biological, including among the latter the Historia Animalium as preparatory to the De Partibus Animalium, and the De Anima and Parva Naturalia, which he called " physical " but we call " psychological" (184 a 10-967 b 27); next, the practical philosophy of the Ethics, including the Eudemian Ethics and the Magna Moralia as earlier and the Nicomachean Ethics as later (1094-124 9 b 25), and of the Politics (1252-1342), with the addition of the newly discovered Athenian Constitution as ancillary to it; finally, the productive science, or art, of the Rhetoric, including the earlier Rhetoric to Alexander and the later Rhetorical Art, and of the Poetics, which was unfinished (1354-end).

Aristotle, who made this great discovery, must have had great difficulty in developing the new investigation of reasoning processes out of dialectic, rhetoric, poetics, grammar, metaphysics, mathematics, physics and ethics; and in disengaging it from other kinds of learning.

He really left the Peripatetics to combine his scattered discourses and treatises into a system, to call it logic, and logic Organon, and to put it first as the instrument of sciences; and it was the Stoics who first called logic a science, and assigned it the first place in their triple classification of science into logic, physics, ethics.

Zabarella to the Arabians, and himself gifted with great logical powers, always deserves study in his editions of the Organon and the Physics, and in his Doctrinae Peripateticae.

Fechner first confused physics and metaphysics in psychophysics, and next proceeded to confuse them again in his work on evolution (Einige Ideen zur SchOpfungs and Entwicklungs-geschichte der Organismen, 1873).

Their interest to the metaphysician is their opposition to physics on the one hand and to theism on the other.

Ernst Mach is a conspicuous instance of a confusion of physics and psychology ending in a scepticism like that of Hume.

If he has any originality, it consists in substituting for the association of ideas the " economy of thinking," by which he means that all theoretical conceptions of physics, such as atoms, molecules, energy, &c., are mere helps to facilitate our consideration of things.

But, with these modifications he accepted the general physics of Aristotle, the metaphysical dualism of matter and form, and the psychology founded upon it.

His opinion with respect to the relation between his science and his religion is expressed in a lecture on mental education delivered in 1854, and printed at the end of his Researches in Chemistry and Physics.

In 1883 he was appointed lecturer in Trinity College, and in the following year Cavendish professor of experimental physics in the university of Cambridge, a position he occupied until his resignation in 1918.

He developed a great research laboratory of experimental physics, attracting numerous workers from many countries and colonies; advances were made in the investigation of the conduction of electricity through gases, in the determination of the charge and mass of the electron and in the development of analysis by means of positive rays.

In 1905 he held the professorship of physics in the Royal Institution, London, in addition to his Cambridge professorship. He was knighted in 1908 and awarded the O.M.

He was the recipient of many British and foreign awards and honours, amongst these being the Royal and Hughes medals of the Royal Society in 1894 and 1902 respectively, the Hodgkins medal of the Smithsonian Institute of Washington in 1902, the Nobel Prize for physics in 1906, enrolment as honorary graduate of many universities, and as honorary fellow of numerous American and continental scientific academies.

In 1918 he was appointed master of Trinity College, Cambridge, and in the following year was elected to a newly established professorship of physics in the Cavendish Laboratory, where he continued to prosecute his researches.

Here we get the link with physics and chemistry alluded to above, which is obtained by the recognition of new forms of energy, interchangeable with what may be called mechanical energy, or that associated with sensible motions and changes of configuration.

For many years, indeed, he came to represent to ordinary Englishmen the typical or ideal professor of physics.

He was for many years professor of higher physics in Turin University.

He was educated first at the college of the Oratorians at Beaune, and then in their college at Lyons - where, at sixteen, the year after he had been learning physics, he was made a teacher of it.

Winkler (1703-1770), professor of physics at Leipzig, substituted a leather cushion for the hand.

The word " Induction," which occurs in only three or four passages throughout all his works (and these again minor ones), is never used by him with the faintest reminiscence of the import assigned to it by Bacon; and, as will be seen, he had nothing but scorn for experimental work in physics.

All these controversial writings on mathematics and physics represent but one half of his activity after the age of p y g Years.

Upon every subject that came within the sweep of his system, except mathematics and physics, his thoughts have been productive of thought.

He then taught physics in Cyzicus and the Propontis, and subsequently, accompanied by a number of pupils, went to Athens.

The Epicurean philosophy is traditionally divided into the three branches of logic, physics and ethics.

In the Epicurean physics there are two parts - a general metaphysic and psychology, and a special explanation of particular phenomena of nature.

This aspect of the Epicurean physics becomes clearer when we look at his mode of rendering particular phenomena intelligible.

In 1899, at the jubilee commemoration of Sir George Stokes, he was Rede lecturer at Cambridge, his subject being the undulatory theory of light and its influence on modern physics; and on that occasion the honorary degree of D.Sc. was conferred on him by the university.

Abauzit at an early age acquired great proficiency in languages, physics and theology.

In later life, he gave up speculative thought and turned to scientific research, especially in mathematics, physics and astronomy.

In 1873 he was appointed professor of physics and telegraphy at the Imperial College of Engineering, Tokio.

On his return to London six years later he became professor of applied physics at the Finsbury College of the City and Guilds of London Technical Institute, and in 1884 he was chosen professor of electrical engineering at the Central Technical College, South Kensington.

He followed his father's trade, but found time to acquire a knowledge of Latin, Greek, mathematics, physics, anatomy and other subjects.

The laboratory examination may be used in subjects like physics, chemistry, geology, zoology, botany, anatomy, physiology, to test powers of manipulation and knowledge of experimental methods.

In 1816 he was invited to Jena to fill the chair of theoretical philosophy (including mathematics and physics, and philosophy proper), and entered upon a crusade against the prevailing Romanticism.

The grand-duke, however, continued to pay him his stipend, and in 1824 he was recalled to Jena as professor of mathematics and physics, receiving permission also to lecture on philosophy in his own rooms to a select number of students.

The whole falls under the three heads of mechanics, physics and " organic " - the content under each varying somewhat in the three editions of the Encyklopadie.

The great commentaries exist only for the Posterior Analytics, Physics, De Caelo, De Anima and Metaphysics.

He studied mathematics and physics in his native town, Groningen, where in 1879 he took his doctor's degree on presenting a dissertation entitled New Proofs of the Earth's Rotation.

In 1913 the Nobel prize for physics was conferred upon him.

An application of these results to solar physics in conjunction with Sir Norman Lockyer led to the view that at least the external layers of the sun cannot consist of matter in the liquid or solid forms, but must be composed of gases or vapours.

Perhaps the most original, and certainly the most permanent in their influence, were his memoirs on the theory of electricity and magnetism, which virtually created a new branch of mathematical physics.

From this time Regnault devoted almost all his attention to practical physics; but in 1847 he published a four-volume treatise on Chemistry which has been translated into many languages.

Fourcroy at the Ecole Polytechnique, where subsequently (1809) he became professor of chemistry, and from 1808 to 1832 he was professor of physics at the Sorbonne, a post which he only resigned for the chair of chemistry at the Jardin des Plantes.

He became professor of experimental physics, first at Palermo and then at Rome, and was appointed to a similar situation at Turin in 1748.

The founder of logic anticipated the latest logic of science, when he recognized, not only the deduction of mathematics, but also the experience of facts followed by deductive explanations of their causes in physics.

On the whole, however, Aristotle, Bacon and Mill, purged from their errors, form one empirical school, gradually growing by adapting itself to the advance of science; a school in which Aristotle was most influenced by Greek deductive Mathematics, Bacon by the rise of empirical physics at the Renaissance, and Mill by the Newtonian combination of empirical facts and mathematical principles in the Principia.

In his definite classification of the sciences,'" into First Philosophy, Mathematics and Physics, it has no place.

We need devices, indeed, to determine priority or superior claim to be " better known absolutely or in the order of nature," but on the whole the problem is fairly faced.4 Of science Aristotle takes for his examples sometimes celestial physics, more often geometry or arithmetic, sometimes a concrete science, e.g.

Celestial physics, with its pure forms and void of all matter save extension, is not such an exemplary science after all.

It is a heuristic process liable to failure, and its application by a nation of talkers even to physics where non-expert opinion is worthless somewhat discredited it.

The example of Aristotle's view of celestial physics as a science of pure forms exhibits both points.

Despite the fact that their philosophic interests lay rather in ethics and physics, their activity The in what they classified as the third department of specula Stoics.

Democritean physics without a calculus had necessarily proved sterile of determinate concrete results, and this was more than enough to ripen the naturalism of the utilitarian school into scepticism.

Plato is full of the faith of mathematical physics.

In scientific method, then, it could but advance, provided physics and mathematics did not again fail of accord.

The new method of physics is verifiable by its fruitfulness, and so free of any immediate danger from dialectic. Its germinal thought may not have been new, but, if not new, it had at least needed rediscovery from the beginning.

Mill aspired after a doctrine of method such as should satisfy the needs of the natural sciences, notably experimental physics and chemistry as understood in the first half of the 19th century and, mutatis mutandis, of the moral sciences naturalistically construed.

But one most important connexion with modern physics must be pointed out.

Hence it is customary to speak of their theories as a mixture of theosophy and physics, or theosophy and chemistry, as the case may be.

Three years later he was elected to the Berlin Academy of Sciences, which in 1754 put him in charge of its chemical laboratory and in 1760 appointed him director of its physics class.

Man's place is not even central, as he appears a temporary inhabitant of a minor planet in one of the lesser stellar systems. Every science is involved, and theology has come into conflict with metaphysics, logic, astronomy, physics, chemistry, geology, zoology, biology, history and even economics and medicine.

In science the process has been reversed; nature ascends, so to speak, into the region of the supernatural and subdues it to itself; the marvellous or miraculous is brought under the domain of natural law, the canons of physics extend over metaphysics, and religion takes its place as one element in the natural relationship of man to his environment.

After acting as assistant to Berthollet, he became successively professor of chemistry at the faculty of sciences and the normal and veterinary schools at Alfort, and then (1820) professor of physics at the Ecole Polytechnique, of which he was appointed director in 1830.

In 1815, in conjunction with Alexis Therese Petit (1791-1820), the professor of physics at the Ecole Polytechnique, he made careful comparisons between the mercury and the air thermometer.

The universities of Bologna, Padua and Salerno had been famous through the middle ages for the study of law, physics and medicine; and during the 15th and 16th centuries the first two still enjoyed celebrity in these faculties.

This early work indicated that whilst there were a number of cases in which the square 1 A Treatise on Electricity and Magnetism (2 vols.), by James Clerk Maxwell, sometime professor of experimental physics in the university of Cambridge.

Succeeding Maxwell as Cavendish professor of physics at Cambridge in 1880, he soon devoted himself especially to the exact redetermination of the practical electrical units in absolute measure.

Electric Waves.-In the decade 1880-1890, the most important advance in electrical physics was, however, that which originated with the astonishing researches of Heinrich Rudolf Hertz (1857-1894).

Speculative or theoretical natural philosophy has to deal with natural substances and qualities and is subdivided into physics and metaphysics.

The principal objects of physics are concrete substances, or abstract though physical qualities.

The research into abstract qualities, the fundamental problem of physics, comes near to the metaphysical study of forms, which indeed differs from the first only in being more general, and in having as its results a form strictly so called, i.e.

Following this summary philosophy come the sciences proper, rising like a pyramid in successive stages, the lowest floor being occupied by natural history or experience, the second by physics, the third, which is next the peak of unity, by metaphysics.

Of the sciences, physics, as has been already seen, deals with the efficient and material, i.e.

In physics, however, these matters are treated only as regards their material or efficient causes, and the result of inquiry into any one case gives no general rule, but only facilitates invention in some similar instance.

Physics inquires into the same qualities, but does not push its investigations into ultimate reality or reach the more general causes.

In physics you wisely note, and therein I agree with you, that after the notions of the first class and the axioms concerning them have been by induction well made out and defined, syllogism may be applied safely; only it must be restrained from leaping at once to the most general notions, and progress must be made through a fit succession of steps."

Of other papers in which he dealt with this and kindred branches of physics may be mentioned "Observations with a Rigid Spectroscope," "Heating of a Disc by Rapid Motion in Vacuo," "Thermal Equilibrium in an Enclosure Containing Matter in Visible Motion," and "Internal Radiation in Uniaxal Crystals."

In 1870, the year in which he was very seriously injured in a railway accident, he was elected professor of physics at Owens 1 On the 6th of November 1878 his body was stolen from St Mark's churchyard in New York, but recovered in 1881 upon the payment of $20,000, and buried in the crypt of the cathedral in Garden City.

In 1858 he became professor of physiology in Heidelberg, and in 1871 he was called to occupy the chair of physics in Berlin.

His great work on Physiological Optics (1856-1866) is by far the most important book that has appeared on the physiology and physics of vision.

Two children were born of this marriage, a son, Robert, who died in 1889, after showing in experimental physics indications of his father's genius, and a daughter, who married a son of Werner von Siemens.

He had a marvellous capacity for work, and between 1516 and 1520, in addition to all his other duties, he published commentaries on the Summulae of Petrus Hispanus, and on the Dialectics, Physics and lesser scientific works of Aristotle, which became the text-books of the university.

Its numerous editions bear witness to its popularity, and until the final fall of Aristotle's physics it continued a popular textbook.

Yet Leibnitz and Sir William Hamilton recognize him as the best modern exponent of the physics and metaphysics of Aristotle.

For the most part he lived in England and Holland, devoting himself to the study of physics and making a living, apparently, by the manufacture of meteorological instruments.

If the recognition of physics and logic as two studies coordinate with ethics is sufficient to differentiate the mature Zeno from the Cynic author of the Republic, no less than from his own heterodox disciple Aristo, the Cleanthes.

Herein lies the key to the entire system of the Stoics, as Cleanthes's epoch-making discovery continually received fresh applications to physics, ethics and epistemology.

So absolutely is the " rare and priceless wisdom " for which we strive identical with virtue itself that the three main divisions of philosophy current at the time and accepted by Zeno - logic, physics and ethics - are defined as the most generic or comprehensive virtues.

The reaction came and left nothing of it all; for five centuries the dominant tone of the older and the newer schools alike was frankly materialistic. " If," says Aristotle, " there is no other substance but the organic substances of nature, physics will be the highest of the sciences," a conclusion which passed for axiomatic until the rise of Neoplatonism.

The analogues therefore of metaphysical problems must be sought in physics; particularly that problem of the causes of things for which the Platonic idea and the Peripatetic " constitutive form " had been, each in its turn, received solutions.

Thus that harmony of separate doctrines which contributes to the impressive simplicity of the Stoic physics is only attained at the cost of offending healthy common sense, for Body itself is robbed of a characteristic attribute.

In Heraclitus the constant flux is a metaphysical notion replaced by the interchange of material elements which Chrysippus stated as a simple proposition of physics.

But they rarely prosecuted researches in physics or astronomy, and the newly created sciences of biology and comparative anatomy received no adequate recognition from them.

No other theory was possible upon the foundation of the Stoic physics.

The ethical theory of the Stoics stands in the closest connexion with their physics, psychology and cosmology.

The physical basis of the system remained unchanged but neglected; all creative force or even original research in the departments of physics and metaphysics vanished.

But his attention is claimed for physics chiefly as a means of elevating the mind, and as making known the wisdom of Providence and the moral government of the world.

Berthollet's most remarkable contribution to chemistry was his Essai de statique chimique (1803), the first systematic attempt to grapple with the problems of chemical physics.

We shall therefore endeavour to apply to this subject the methods used in Thermodynamics, and where these fail us we shall have recourse to the hypotheses of molecular physics.

He was educated at Midhurst grammar school and at the Royal College of Science, where he was trained in physics, chemistry, astronomy, geology and biology.

In physics, Descartes had prepared the way for the final triumph of the mechanical explanation of the world in Newton's system.

He obtained a B.Sc. from London University in 1875 with high honours and a D.Sc. in 1878, when he became professor of experimental physics in University College, Bristol.

By that time he had removed to London, becoming professor of Physics in the City and Guilds of London Technical College, Finsbury, in 1885 and subsequently its principal.

The education which he received at Malmesbury included a smattering of logic and physics; but moral philosophy and history, especially the latter, were the subjects to which he devoted most attention.

Schering the Disquisitiones arithmeticae, (2) Theory of Numbers, (3) Analysis, (4) Geometry and Method of Least Squares, (5) Mathematical Physics, (6) Astronomy, and (7) the Theoria motus corporum coelestium.

After acting as privat-docent at Berlin for some time, he became extraordinary professor of physics at Breslau in 1850.

Four years later he was appointed professor of physics at Heidelberg, and in 1875 he was transferred to Berlin, where he died on the 17th of October 1887.

Kirchhoff's contributions to mathematical physics were numerous and important, his strength lying in his powers of stating a new physical problem in terms of mathematics, not merely in working out the solution after it had been so formulated.

This idea of universal activity has in a sense made physics itself a branch of history.

In 1847 he was made professor of physics at Bonn; and from that time his scientific activity took a new and astonishing turn.

He published numerous works on different branches of physics, including A Complete Treatise on Electricity (1777), Treatise on the Nature and Properties of Air and other permanently Elastic Fluids (1781), History and Practice of Aerostation (1785), Treatise on Magnetism (1787), Elements of Natural and Experimental Philosophy (1803), Theory and Practice of Medical Electricity (1780), and Medical Properties of Factitious Air (1798).

Besides pictures, the master seems also to have shown and explained to his visitors some of his vast store of notes and observations on anatomy and physics.

Logic, ethics and physics, psychology, theory of knowledge and metaphysics are all fused together by Plato in a semi-religious synthesis.

The details of physics, for example, were abandoned to the scientific specialist, and philosophy restricted itself in this department to the question of the relation of the physical universe to the ultimate ground or author of things.

In the same way, physics may be said to assume the notion of material atoms and forces.

We also possess in fragments a History of Physics, a treatise On Stones, and a work On Sensation, and certain metaphysical 'Airopiac, which probably once formed part of a systematic treatise.

His works embraced politics, astronomy, medicine, music, theology, jurisprudence, physics, grammar and history.

But the work there was not to his liking, and after a short time he gave it up for an instructorship in natural science at the university of Wooster, Ohio, which in turn he resigned in order to return to Troy as assistant professor of physics.

Finally, in 1876, he became the first occupant of the chair of physics at the Johns Hopkins University, Baltimore, a position which he retained until his premature death on the 16th of April 1901.

When the managers of the Johns Hopkins University asked advice in Europe as to whom they should make their professor of physics, he was pointed out in all quarters as the best man for the post.

In the interval between his election and the assumption of his duties at Baltimore, he studied physics under Helmholtz at Berlin, and carried out a well-known research on the effect of an electrically charged body in motion, showing it to give rise to a magnetic field.

Hence our only guides are such general laws of mechanics and physics as we can hardly believe any circumstances will falsify.

In 1730 he became professor of physics, and in 1733 he succeeded Daniel Bernoulli in the chair of mathematics.

He achieved the rare distinction of obtaining an optime for both Greek and for physics.

He went, however, to the university of Bologna, where his famous kinswoman, Laura Bassi, was professor of physics, and it is to her influence that his scientific impulse has been usually attributed.

He dedicated no small portion of his time to the study of pure mathematics, to investigations in physics and chemistry, and even to anatomy and architecture; and there can be no doubt that this varied learning enhanced considerably the value of many of his judicial decisions.

Applications to Physics are numerous, but are usually only of special interest.

During the years 1833-1843 he contributed very largely to the first edition of the [[Penny]] Cyclopaedia, writing chiefly on mathematics, astronomy, physics and biography.

Jean Pierre Minckelers, professor of natural philosophy in the university of Louvain, and later of chemistry and physics at Maestricht, made experiments on distilling gas from coal with the view of obtaining a permanent gas sufficiently light for filling balloons, and in 1785 experimentally lighted his lecture room with gas so obtained as a demonstration to his students, but no commercial application was made of the fact.

The nature of the dream, in which the elder Scipio appears to his (adopted) grandson, and describes the life of the good after death and the constitution of the universe from the Stoic point of view, gives occasion for Macrobius to discourse upon many points of physics in a series of essays interesting as showing the astronomical notions then current.

In 1757 he settled in St Petersburg as member of the imperial academy of sciences and professor of physics, and remained there till his retirement in 1798.

On completing his noviciate, which was spent at Rome, he studied mathematics and physics at the Collegium Romanum; and so brilliant was his progress in these sciences that in 1740 he was appointed professor of mathematics in the college.

And many scientific thinkers, while professing allegiance to a theory which insists upon the independence of each parallel series, in reality tacitly assume the superior importance if not the controlling force of the physical over the psychical terms. But a mere insistence upon the complete independence of the physical series coupled with the belief that its changes are wholly explicable as modes of motion, that the study of molecular physics is competent to explain all the phenomena of life and organic movements, is sufficient to eliminate the possibility of spontaneity and free origination from the universe.

He became professor of physics at Bologna in 1798, in succession to his teacher Sebastiano Canterzani (1734-1819).

Even Socrates, in spite of his aversion to physics, was led by pious reflection to expound a teleological view of the physical world, as ordered in all its parts by divine wisdom for the realization of some divine end; and, in the metaphysical turn which Plato gave to this view, he was probably anticipated by Euclid of Megara, who held that the one real being is " that which we call by many names, Good, Wisdom, Reason or God," to which Plato, raising to a loftier significance the Socratic identification of the beautiful with the useful, added the further name of Absolute Beauty, explaining how man's love of the beautiful finally reveals itself as the yearning for the end and essence of being.

The physics and psychology of Descartes were much studied in England, and his metaphysical system was certainly the most important antecedent of Locke's; but Descartes hardly touched ethics proper.

In 1763 he entered Göttingen university, where in 1769 he became extraordinary professor of physics, and six years later ordinary professor.

Solar physics has profited enormously by the abolition of glare during total eclipses.

It is divided, according to the usual fashion of the Epicureans, into logic (which, with Gassendi as with Epicurus, is truly canonic), physics and ethics.

In the second part of the Syntagma, the physics, there is more that deserves attention; but here, too, appears in the most glaring manner the inner contradiction between Gassendi's fundamental principles.

While approving of the Epicurean physics, he rejects altogether the Epicurean negation of God and particular providence.

But others were not slow to draw the obvious conclusions; and it may be conjectured that Gorgias's sceptical development of the Zenonian logic contributed, not less than Protagoras's sceptical development of the Ionian physics, to the diversion of the intellectual energies of Greece from the pursuit of truth to the pursuit of culture.

He became professor of mathematics in the Jesuits' college at Cologne in 1817 and in the polytechnic school of Nuremberg in 1833, and in 1852 professor of experimental physics in the university of Munich, where he died on the 7th of July 1854.

Nowadays "Ohm's Law," as it is called, in which all that is most valuable in the pamphlet is summarized, is as universally known as anything in physics.

But under the influence of Thomas Thomson (1773-1852), the professor of chemistry, he developed a taste for experimental science and especially for molecular physics, a subject which formed his main preoccupation throughout his life.

By attention to crop rotation, soil physics and world-wide search for plants adapted to the Great Plains (such as the U.S. Department of Agriculture has long been conducting), a very great deal can be accomplished - no one can say how much; but certainly the Western must long remain at a great disadvantage in comparison with the Eastern portion of the state as regards the growth of cereals.

Leslie's main contributions to physics were made by the help of the "differential thermometer," an instrument whose invention was contested with him by Count Rumford.

This chair he exchanged for that of mathematics and physics at Yale in 1825; in 1836, when this professorship was divided, he retained that of astronomy and natural philosophy.

In 1779 a chair of physics was founded in Pavia, and Volta was chosen to occupy it.

A short sojourn at Freiburg in Switzerland was followed by his appointment in 1831 to the newly-created chair of mathematical physics at the university of Turin.

These are mainly embodied in his three great treatises, Cours d'analyse de l'Ecole Polytechnique (1821); Le Calcul infinitesimal (1823); Lecons sur les applications du calcul infinitesimal a la g'ometrie (1826-1828); and also in his courses of mechanics (for the Ecole Polytechnique), higher algebra (for the Faculte des Sciences), and of mathematical physics (for the College de France).

During his university course, which began in 1740, Kant was principally attracted towards mathematics and physics.

His lectures, at first mainly upon physics, gradually expanded until nearly all descriptions of philosophy were included under them.

His memory began to fail, and a large work at which he wrought night and day, on the connexion between physics and metaphysics, was found to be only a repetition of his already published doctrines.

He studied at the university of Halle, where he took his doctor's degree in 1826 and became extraordinary professor of physics in 5828.

Three years later he removed to Göttingen as professor of physics, and remained there till 1837, when he was one of the seven professors who were expelled from their chairs for protesting against the action of the king of Hanover (duke of Cumberland) in suspending the constitution.

A period of retirement followed this episode, but in 1843 he accepted the chair of physics at Leipzig, and six years later returned to Göttingen, where he died on the 23rd of June 1891.
