Pioneers of Science The hypothesis of Laplace fits in remarkably well with the theory put forward in later times by Helmholtz, that the heat of the sun is kept up by the continual contraction of its mass. Astronomy of To-day A Popular Introduction in Non-Technical Language But while recognizing the incompleteness of the evidence, it seems to me that it goes far to justify the hypothesis of Olbers, and is quite incongruous with that of Laplace. Essays: Scientific, Political, & Speculative, Vol. I So far the results of Laplace’s hypothesis are in marked accordance with experiment; but if we follow it out further, discordances begin to manifest themselves. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 3 "Capefigue" to "Carneades" It was remarked by Laplace that this invention was the means of doubling the life of an astronomer, besides enabling him to avoid errors and the tediousness associated with long and abstruse calculations. The Astronomy of Milton's 'Paradise Lost' When Laplace and Lagrange investigated the question of the stability or instability of the solar system, they did so on the hypothesis that the bodies composing it were rigid. Pioneers of Science In the detailed account of it which they have set forth, they show that those anomalies which were stumbling-blocks to Laplace's theory do not contradict theirs. Astronomy of To-day A Popular Introduction in Non-Technical Language The general nature of Laplace's theory scarcely needs stating.

Essays: Scientific, Political, & Speculative, Vol. I How has it fared with Laplace's sketch of the origin of the world? A Popular History of Astronomy During the Nineteenth Century Fourth Edition There is thus, in Laplace's theory, nothing, strictly speaking, hypothetical; it is an example of legitimate reasoning from a present effect to a possible past cause, according to the known laws of that cause. A System Of Logic, Ratiocinative And Inductive Laplace could not have known this for certain, but he suspected it. Pioneers of Science Saturn's ring was considered, by Laplace, as the only portion of the system left which still showed traces of this evolutionary process.

Macaria M. Faye's leading contention is that, under the circumstances assumed by Laplace, not the two outer planets alone, but the whole company must have been possessed of retrograde rotation. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Laplace's argument, therefore, is faulty even as applied to his own case. A System Of Logic, Ratiocinative And Inductive Laplace pictured to himself this mass shrinking and thereby whirling more and more rapidly. Pioneers of Science The French astronomer, Faye, also proposed to modify Laplace's theory by assuming that the nebula broke up into rings all at once, and not in detail, as Laplace had wished to suppose.

A Tour of the Missions Observations and Conclusions Newton and Laplace had perceived every detail of their laws. Pioneers of Science The idea that rings would at all be left behind at certain intervals during the contraction of the nebula is, perhaps, one of the weakest points in Laplace's hypothesis. Astronomy of To-day A Popular Introduction in Non-Technical Language The demonstration of the principle of virtual velocities is so easy and direct in Laplace that I cannot imagine anything capable of rendering it plainer than he has done. Personal Recollections, from Early Life to Old Age, of Mary Somerville It was one of Laplace's highest triumphs to have found an explanation of this puzzling fact. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Such is, in fact, the doctrine of the origin of our system which has been advanced in that celebrated speculation known as the nebular theory of Laplace. The Story of the Heavens But their perturbations would be very minute, and moreover, on Laplace's theory, would only result in periodic changes, provided each mass were rigid. Pioneers of Science It is also thought that such interlaced paths, as those in which the asteroids and the little planet Eros move, are most unlikely to have been produced as a result of Laplace's nebula. Astronomy of To-day A Popular Introduction in Non-Technical Language Mrs. Somerville is the lady who, Laplace says, is the only woman who understands his works. Personal Recollections, from Early Life to Old Age, of Mary Somerville They tend, in general, to reduce the amount of acceleration left unaccounted for by Laplace's gravitational theory, and proportionately to diminish the importance of the part played by tidal friction. A Popular History of Astronomy During the Nineteenth Century Fourth Edition A hundred years have passed since Laplace, with some diffidence, set forth his hypothesis as to the mode of formation of the solar system. The Story of the Heavens Perhaps one ought rather to say trying than deteriorating; for they seem trying to a strong character, deteriorating to a weak one—and unfortunately, Laplace must be classed in this latter category. Pioneers of Science Laplace's conception was much less ambitious, for it did not attempt to explain the origin of the entire universe, but only of the solar system. Astronomy of To-day A Popular Introduction in Non-Technical Language On March 15, Marquis Pierre Simon de Laplace, one of the greatest mathematicians and physical astronomers of all time, died at Arcueil. A History of the Nineteenth Century, Year by Year Volume Two (of Three) Strangely enough, it seems to have been propounded in complete independence of Laplace's nebular hypothesis as to the origin of the solar system. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Laplace, however, showed that if the satellites revolved nearly in this way, then their mutual perturbations, in accordance with the law of gravitation, would preserve them in this relative position for ever. The Story of the Heavens Next among the investigations of Lagrange and Laplace we will mention the long inequality of Jupiter and Saturn. Pioneers of Science Laplace had saved the theoretical stability of the motions of a fine ring at the expense of the ring's power of resisting the strains to which it would be exposed. Myths and Marvels of Astronomy Shortly after the death of Laplace, Ludwig van Beethoven died in Vienna on March 26. A History of the Nineteenth Century, Year by Year Volume Two (of Three) It was virtually brought to a close when Laplace explained to the French Academy, November 19, 1787, the cause of the moon's accelerated motion. A Popular History of Astronomy During the Nineteenth Century Fourth Edition It fortunately happens, however, that the results to which Lagrange and Laplace were conducted, and which have been abundantly confirmed by the labours of other mathematicians, admit of being described in simple language. The Story of the Heavens And Laplace suggested the "nebular hypothesis" concerning the origin of sun and planets: a hypothesis previously suggested, and to some extent, elaborated, by Kant. Pioneers of Science Laplace opened his eyes and answered with deep gravity. Myths and Marvels of Astronomy But is not a symbol wanted by Laplace; nor can we see how it could have been; in fact, it is not recognized in algebra. A Budget of Paradoxes, Volume II The general outcome of Mr. Darwin's researches has been to leave Laplace's cosmogony untouched. A Popular History of Astronomy During the Nineteenth Century Fourth Edition It is what we deduce from the calculation of a Newton and a Laplace on the one hand, and from the industrious observation of facts by a Murchison and a Lyell on the other. The World's Greatest Books — Volume 15 — Science This was the problem Laplace set himself to work out. Pioneers of Science It is well known, indeed, that Newton himself did not disdain to study the questions thus suggested; and the speculations of the ingenious Dupuis found favour with the great mathematician Laplace. Myths and Marvels of Astronomy Laplace and Horace are about equally well imitated. A Budget of Paradoxes, Volume II Moreover, it is a question whether the relative ages of the planets do not follow an order just the reverse of that concluded by Laplace. A Popular History of Astronomy During the Nineteenth Century Fourth Edition If among the multitude of persons solely occupied with astronomy, even then, all that these people knew might have been discovered in a few centuries, when only 300 years intervened between Copernicus and Laplace. The World's Greatest Books — Volume 15 — Science Since the time of Laplace the nebular hypothesis has had ups and downs of credence, sometimes being largely believed in, sometimes being almost ignored. Pioneers of Science It is singular that Herschel, who, though not versed in the methods of the higher mathematics, had considerable native power as a mathematician, was unable to perceive the force of Laplace's reasoning. Myths and Marvels of Astronomy But the American got nearer to Horace than the martyr-philosopher to Laplace. A Budget of Paradoxes, Volume II This is all quite true as Laplace put it; but it is not enough. A Popular History of Astronomy During the Nineteenth Century Fourth Edition The sun and the planets had already been shown by Laplace to be very probably derived from a primitive more or less undifferentiated nebula. Mysticism and Logic and Other Essays Such, crudely and baldly, is the famous nebular hypothesis of Laplace. Pioneers of Science It was here that Laplace left the problem. Myths and Marvels of Astronomy Ivory was of that note in the scientific world which may be guessed from Laplace's description of him as the first geometer in Britain and one of the first in Europe. A Budget of Paradoxes, Volume II It was presented by Laplace with diffidence, as a speculation unfortified by numerical buttresses of any kind, yet with visible exultation at having, as he thought, penetrated the birth-secret of our system. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Great scientific names—Laplace, Bichat, Cuvier, Lamarck—testify to the fact that a movement which made the eighteenth century illustrious had not spent its force. A History of French Literature Short Histories of the Literatures of the World: II. Lagrange and Laplace, both tremendous mathematicians, worked very much in alliance, and completed Newton's work. Pioneers of Science There is nothing in nature in the remotest degree resembling the arrangement imagined by Laplace, which indeed appears on à priori grounds impossible. Myths and Marvels of Astronomy Did Kant, Laplace, and William Herschel quit their legitimate spheres, when they prolonged the intellectual vision beyond the boundary of experience, and propounded the nebular theory? Fragments of science, V. 1-2 But recent science raises many objections to the details, if it supplies some degree of confirmation to the fundamental idea of Laplace's cosmogony. A Popular History of Astronomy During the Nineteenth Century Fourth Edition It implies the awakening of human intelligence, the increasing of the inventive spirit tenfold, a hundredfold; it is the dawn of a new science—the science of men like Laplace, Lamarck, Lavoisier. The Conquest of Bread A list of some of the principal astronomical researches of Lagrange and Laplace:—Libration of the moon. Pioneers of Science Now, it seems to us that there is quite as much of hypothesis in this speculation of Laplace as in the undulatory theory of light. Blackwood's Edinburgh Magazine, No. CCCXXXVI. October, 1843. Vol. LIV. I hold the nebular theory as it was held by Kant, Laplace, and William Herschel, and as it is held by the best scientific intellects of to-day. Fragments of science, V. 1-2 Their rotational velocity being thus relatively small, they formed "inner rings," very much nearer to the centre of condensation than would have been possible on the unmodified theory of Laplace. A Popular History of Astronomy During the Nineteenth Century Fourth Edition No reviewer will object to me that I have omitted Young, Laplace, etc. A Budget of Paradoxes, Volume I Laplace was the son of a small farmer or peasant of Normandy. Pioneers of Science But a condition, we think, very superior to the astronomical speculation of Laplace, which Mr Mill, after scrutinizing the preceding hypothesis with the utmost strictness, is disposed to treat with singular indulgence. Blackwood's Edinburgh Magazine, No. CCCXXXVI. October, 1843. Vol. LIV. As to the Law of Gravitation, and astronomers' formulas, remember that these formulas worked out in the time of Laplace as well as they do now. The Book of the Damned M. Faye, as we have seen, objected to Laplace's scheme that only retrograde secondary systems could be produced by it. A Popular History of Astronomy During the Nineteenth Century Fourth Edition He raised no difficulty about π; he knew the forms of Laplace's results, and he was much interested.

Lamarck, the Founder of Evolution His Life and Work Such a man as Laplace, alone, is sufficient to redeem an entire people from these imputations. Recollections of Europe Laplace's hypothesis has been subjected in recent years to much criticism, and there is good reason to doubt whether his description of the mode of evolution of our solar system is correct in every particular. The New Heavens Modest as was the public position that he held, he may now fairly be considered the greatest master of celestial mechanics since Laplace. The Reminiscences of an Astronomer That at the north-western extremity had long been known to astronomers under the name of Cape Laplace. Edison's Conquest of Mars The verdict of humanity concerning Sir Isaac Newton has been summed up for us thus by Laplace: "His work was pre-eminent above all other products of the human intellect." Little Journeys to the Homes of the Great - Volume 12 Little Journeys to the Homes of Great Scientists And now we go back to Kant and Laplace for our demonstration. Our Unitarian Gospel And if such stages can be detected, do they afford indications of the gradual diminution in volume which Laplace imagined the sun to experience? The New Heavens I should not have been surprised to learn that even the Hibernian who fed the fire had imbibed so much of the spirit of the place as to admire the genius of Laplace and Lagrange. The Reminiscences of an Astronomer Taken in connection with what we know of the nebulæ, the proof of Laplace's nebular hypothesis may fairly be regarded as complete.

Biographies of Distinguished Scientific Men The supreme leaders in science, the men whose discoveries have been fecundating and fundamental, seem to be at least seven—Euclid, Archimedes, Copernicus, Newton, Laplace, Lavoisier, and Darwin. Inquiries and Opinions Kant and Laplace came first in time, as astronomy comes first in logical order. Falling in Love With Other Essays on More Exact Branches of Science Laplace believed he had accounted for this phænomenon by the fact that the eccentricity of the earth's orbit has been diminishing throughout these 3,000 years. Lay Sermons, Addresses and Reviews Does the essentially material hypothesis of Kant and Laplace account for an infinite past as thinkably as it accounts for the infinite future?

Biographies of Distinguished Scientific Men Laplace has calculated that a force five times greater than that of an ordinary cannon would be sufficient to send a bolide from the Moon to the Earth. All Around the Moon Kant and Laplace had worked out the development of suns and earths from white-hot star-clouds. Falling in Love With Other Essays on More Exact Branches of Science I assert, with Laplace, that there is no need of the hypothesis of a creator. The Turtles of Tasman Accepting the hypothesis of Kant and Laplace in its widest extension, we are referred to a primitive condition of wide material diffusion, and necessarily too of material instability. The Birth-Time of the World and Other Scientific Essays Nor is this honour decreased by the ulterior and considerable improvements that the science has since received; even the discoveries of Lagrange and of Laplace have left this honour intact. Biographies of Distinguished Scientific Men Or again, they had proved impossible of combination with any religion, as in the case of Laplace. An Outline of the History of Christian Thought Since Kant Laplace cleverly evades the difficulty by not taking from the hand of the Creator diffused gas, but a sun with an atmosphere filling space to the orbit of Neptune, and already in revolution. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work Arago, De Laplace, or Biot, never gave me so much pleasure as the discovery of a theoretical truth or the confirmation of a calculation by experiment.' The Advance of Science in the Last Half-Century Kant and Laplace, material hypothesis of, does not account for the past, 290. The Birth-Time of the World and Other Scientific Essays Whatever came from the pen of M. de Laplace was always marked by the stamp of reason and of evidence. Biographies of Distinguished Scientific Men It must be acknowledged, however, that the idea of Lavoisier and Laplace was rather vague and even inexact on one important point. The New Physics and Its Evolution And Laplace said of it to Napoleon, "I have no need of the hypothesis of a god." Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work We know that Newton who completes Galileo, Maxwell who follows Laplace, Helmholtz who uses the results of Joule, can have no conflicting jealousies. The Unity of Civilization From these considerations Kant and Laplace formulated the nebular hypothesis, resting it on gravitation alone, for at that time the science of the conservation of energy was practically unknown. Scientific American Supplement No. 819, September 12, 1891 We shall be somewhat less concise in noticing the labours of Laplace. Biographies of Distinguished Scientific Men Most of the physicists of that period, however, did not share the prudent doubts of Lavoisier and Laplace. The New Physics and Its Evolution Laplace has given us proof that the period of the earth's axial rotation has not changed 1/100 of a second of time in two thousand years. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work Laplace is said to have stated that he had not found the hypothesis of God necessary in order to construct his scheme of the origin of the Universe, and it is very true. Tragic Sense Of Life On the view that the material of the condensing solar system consisted of separate particles or masses, we had no longer the fluid pressure which was an essential part of Laplace's theory. Scientific American Supplement No. 819, September 12, 1891 This depends on circumstances which calculation disclosed to Laplace, and which, upon a superficial view of the subject, would not seem to be capable of exercising so great an influence. Biographies of Distinguished Scientific Men From various astronomical observations, Laplace concluded that its velocity, in any case, must exceed fifty million times that of light. The New Physics and Its Evolution Page 172 Laplace mathematically demonstrated that it cannot be uniform and solid, and survive. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work The structure of the heavens is here reduced to the simple solution of a great problem in mechanics; yet Laplace's work has never yet been accused of incompleteness and want of profundity.

Letters on International Copyright; Second Edition Dr. Mott stated that when Newton first pointed out this discrepancy of 174 feet, the theory should have been dropped at once, and later on he showed the consequences of Laplace's heat and cold theory. Scientific American Supplement, No. 470, January 3, 1885 Laplace proved by a general analysis, that the roots of the equation are real and unequal, whence it followed that neither the eccentricity nor the inclination will vary in any case to an indefinite extent. Biographies of Distinguished Scientific Men He so far succeeded, that men so celebrated as Laplace and Malus, who lived till 1812, and Biot and Brewster, who lived till our own time, were found among his disciples. Six Lectures on Light Delivered In The United States In 1872-1873 There are certain facts which are apparent, but for an explanation of their true theory such men as Laplace, Newton, and Airy have labored in vain.

Library of the World's Best Literature, Ancient and Modern — Volume 2 Nor is it quite certain that Laplace’s proofs of the instantaneous propagation of gravity are final. History of Astronomy This is due in small part to discoveries since Laplace's time, but chiefly to a more careful consideration of the fundamental principles involved. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The importance of this element induced Laplace to examine whether its numerical value might not be liable to vary from internal causes such as earthquakes and volcanoes. Biographies of Distinguished Scientific Men The topmost letter had a foreign stamp, and she recognised the writing of Laplace.

Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 As soon as the terrible news was known, Madame Laplace wrote to Bailly, persuading him, under covert expressions, to give up the intended project. Biographies of Distinguished Scientific Men Some astronomers, indeed, now reject Laplace's hypothesis in toto, preferring to think that even our solar system originated from a spiral nebula. Curiosities of the Sky Ampere developed the idea of Laplace into a definite plan, and in 1830 or thereabout Ritchie, in London, and Baron Schilling, in St. Petersburg, exhibited experimental models. The Story of Electricity It has been shown that Laplace's Nebular Hypothesis, when substituted for the action of a Creator, broke down in three important points. Story of Creation as Told By Theology and By Science M. Picavet has grouped around them, along with many obscurer names, the great scientific men of the time, like Laplace, Bichat, Lamarck, as all in the direct line of eighteenth century thought. The Idea of Progress An inguiry into its origin and growth But the researches of Herschel and of Laplace showed later that the orbit of the new body was nearly circular, and Uranus was elevated to the rank of a planet. Biographies of Distinguished Scientific Men As we shall see later, the peculiarity of the spectra of the spiral nebulæ is appealed to in support of a modern substitute for Laplace's hypothesis. Curiosities of the Sky He can trace his scientific descent from generation to generation, through the periods of Arabian and medieval science, through Copernicus, Kepler, Newton, Laplace, and Herschel, down to the present time. Side-Lights on Astronomy and Kindred Fields of Popular Science Considered then as a substitute for the action of an intelligent Creator, Laplace's theory utterly breaks down in three points, which, as they will have to be referred to hereafter, it is well to recapitulate. Story of Creation as Told By Theology and By Science Newton and Laplace need myriads of age and thick-strewn celestial areas. Essays — First Series We have just explained how Laplace demonstrated that the solar system can experience only small periodic oscillations around a certain mean state. Biographies of Distinguished Scientific Men Laplace was one of the ablest mathematicians that ever lived, but he had never seen a spiral nebula; if he had, he might have invented a hypothesis to suit its phenomena. Curiosities of the Sky His translation of the Mecanique Celeste made an epoch in American science by bringing the great work of Laplace down to the reach of the best American students of his time. Side-Lights on Astronomy and Kindred Fields of Popular Science This theory, like that of Laplace, had its origin among the French Academicians, at the close of the last century. Story of Creation as Told By Theology and By Science Laplace also praised him for the clearness of his demonstrations, and invited Biot to accompany him home. Character Laplace, in effect, has devoted a chapter of his splendid work to an examination of the oscillations which the attractive force of the moon is capable of producing in our atmosphere. Biographies of Distinguished Scientific Men In mathematics do you look upon Euler, Laplace, or Gauss as fools? Virgin Soil An opposite conclusion was reached by Laplace, who showed that the effect of this force was neutralized by forces producing the wave and acting in the opposite direction. Side-Lights on Astronomy and Kindred Fields of Popular Science We come now to the consideration of the Nebular Theory of Laplace, in so far as it is opposed to the Mosaic account. Story of Creation as Told By Theology and By Science Arrived there, Laplace took from a closet in his study a paper, yellow with age, and handed it to the young philosopher.

Character Upon the death of Lémontey, the French Academy, where Laplace and Cuvier already represented the sciences, called also Fourier into its bosom. Biographies of Distinguished Scientific Men To do him justice, however, if he is ill informed on these points, there are other points on which Newton and Laplace were mere children when compared with him. Miscellaneous Writings and Speeches — Volume 4 But those letters seem to have elicited no reply, whereupon Laplace wrote to D'Alembert submitting a discussion on some point in Dynamics. Great Astronomers "Yes—have changed very much, as you see," here interrupted the gentleman who had broken the shins of Ma'm'selle Laplace. The Works of Edgar Allan Poe — Volume 4 But Laplace's habits had been formed in the study, and he was too old to adapt them to the purposes of practical life.

The Story of Evolution He, therefore, of all the ancients, as Laplace remarks, had the most correct ideas of the grandeur of the universe. History of the Conflict Between Religion and Science The theory of the planetary movements is identified with the name of Laplace; hardly is a passing allusion made to the eminent labours of D'Alembert, of Clairaut, of Euler, of Lagrange. Biographies of Distinguished Scientific Men On the contrary, a bitter feud ensued, in which Arago was opposed by the "Jupiter Olympus of the Academy," Laplace, by the only less famous Poisson, and by the younger but hardly less able Biot. A History of Science — Volume 3 Laplace has, in fact, created whole tracts of science, some of which have been subsequently developed with much advantage in the prosecution of the study of Nature.
