Harper's New Monthly Magazine, Volume 1, No. 4, September, 1850 This is the nebular hypothesis of the astronomer. A Critique of the Theory of Evolution They have, indeed, proved that the period of time to be drawn upon is not infinite; but the nebular hypothesis, to say nothing of common-sense, carried us as far as that long ago. A History of Science, Volume 5(of 5) Aspects Of Recent Science In his poem to Fitzgerald, Tennyson draws upon the nebular hypothesis for an image:— "A planet equal to the sun Which cast it, that large infidel Your Omar."

Pioneers of Science Everyone knew that by these small condensations of nebular promise stars were eventually evolved, and to have at his disposal the earnings of a star.... The Dust Flower The fact that matter passed through an endless series of other forms before arriving at the nebular state is not excluded from this conception but is on the other hand rather included in it. Landmarks of Scientific Socialism "Anti-Duehring" The nebular hypothesis was first propounded by Kant, who suggested that the sun and planets originated from a vast and diffused mass of cosmical matter. The Astronomy of Milton's 'Paradise Lost' And if they differ, can we, from the process of nebular condensation, infer the conditions under which they assume one or other character?

A Popular History of Astronomy During the Nineteenth Century Fourth Edition In 1811 Herschel read a paper before the Royal Society in which he propounded his famous nebular hypothesis, and stated his reasons for believing that nebul�, by their gradual condensation, were transformed into stars. The Astronomy of Milton's 'Paradise Lost' For this reason I have decided to set forth separately some views concerning the genesis of the so-called elements during nebular condensation, and concerning the accompanying physical effects. Essays: Scientific, Political, & Speculative, Vol. I 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 Before bedtime I was reading out of two books; a little pamphlet on astronomy containing the nebular theory, and another that told about the planetary chain. Child and Country A Book of the Younger Generation But its effects must have been produced while they were still in an unformed, perhaps a nebular condition.

A Popular History of Astronomy During the Nineteenth Century Fourth Edition No attempt has been made to supplant the nebular hypothesis by any other theory of cosmical evolution. The Astronomy of Milton's 'Paradise Lost' Practically demonstrated as this process now is, we may say that the doctrine of nebular genesis passes from the region of hypothesis into the region of established truth. Essays: Scientific, Political, & Speculative, Vol. I Such, crudely and baldly, is the famous nebular hypothesis of Laplace. Pioneers of Science For us, at present, it is enough that the nebular hypothesis is rejected by some of the greatest astronomers that have lived. Christianity and Greek Philosophy or, the relation between spontaneous and reflective thought in Greece and the positive teaching of Christ and His Apostles In 1825 Herschel undertook, and executed with great assiduity during the ensuing eight years, a general survey of the northern heavens, directed chiefly towards the verification of his father's nebular discoveries. A Popular History of Astronomy During the Nineteenth Century Fourth Edition The nebular theory is incapable of proof or demonstration; but modern discoveries tend to support the accuracy of its conclusions, and its principles have now been adopted by the majority of philosophic thinkers. The Astronomy of Milton's 'Paradise Lost' Hence arose the inquiry—What structure will result from the process of nebular condensation? Essays: Scientific, Political, & Speculative, Vol. I The solar tides are, however, much too small to appreciably push any planet away, hence we are not to suppose that the planets originated by budding from the sun, in contradiction of the nebular hypothesis. Pioneers of Science 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 It is strong in the spectra of many planetaries; it helped to characterise the nebular metamorphosis of Nova Aurigæ, yet failed to appear in Nova Persei. A Popular History of Astronomy During the Nineteenth Century Fourth Edition According to the nebular hypothesis, these bodies are the consolidated portions of a nebulous ring which remained separate instead of having coalesced into one mass so as to form a planet. The Astronomy of Milton's 'Paradise Lost' Astronomy delights in infinitudes of time and space: it sees worlds arise, burn at first with the feeble light of a nebular mass, glow like suns, become chilled, covered with spots, and then become condensed. Essay on the Creative Imagination But the development of mechanics paved the way for a definite scientific theory, the so-called "nebular hypothesis," announced by La Place in 1796, and by the philosopher Kant at a still earlier date. The Approach to Philosophy This nebular theory is not confined to the history of our sun. The Story of the Heavens An approximate coincidence between the chief nebular line and a "fluting" of magnesium having been alleged by Lockyer in support of his meteoritic hypothesis of nebular constitution, it became of interest to ascertain its reality.

Time and Tide A Romance of the Moon Let us look first at the nebular hypothesis. A Theory of Creation: A Review of 'Vestiges of the Natural History of Creation' If, then, our sun has passed through such changes as the nebular theory requires, may we not anticipate that similar phenomena should be met with in other stars? The Story of the Heavens His memorable detection of nebular movement in line of sight ensued as a consequence. A Popular History of Astronomy During the Nineteenth Century Fourth Edition 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 Of course it would be understood that tidal evolution is in no sense a rival doctrine to that of the nebular theory. Time and Tide A Romance of the Moon But to see her radiant with intellectual enthusiasm, one has but to start a discussion of the nebular hypothesis, or to touch upon the atomic theory, or doubt the inconceivability of matter. The Arena Volume 4, No. 23, October, 1891 The nebular origin of the solar system receives considerable countenance from the study of the sidereal heavens. The Story of the Heavens The anomaly of seeming nebular fixity has nevertheless been removed; and the problem of nebular motion has begun to be solved through the demonstrated possibility of its spectroscopic investigation.

Fragments of science, V. 1-2 Darwin never made a point better; and the nebular hypothesis and the origin of species are worked out with conjectures, fanciful flights, queer conceits, poetic comparisons, far-reaching analogies, and most astounding leaps of imagination. Little Journeys to the Homes of the Great Philosophers, Volume 8 How they would like to grasp the significance of the nebular theory, the most overwhelming of all theories! Mental Efficiency And Other Hints to Men and Women I suspect the nebular hypothesis had got into the poor man's head by reading, in some singular mixture with what it found there. A Budget of Paradoxes, Volume I All of these gave the green ray fundamental to the nebular spectrum, and emanating from an unknown form of matter named by Sir William Huggins "nebulum." A Popular History of Astronomy During the Nineteenth Century Fourth Edition His vaguely grand conception of the atoms falling eternally through space, suggested the nebular hypothesis to Kant, its first propounder. Fragments of science, V. 1-2 Some inquirers—arguing from the 'nebular theory,' which assumes the formation of the several planets, one after another, from nebulous matter—have supposed the zodiacal light to be a remnant of that matter yet unconcentrated.

On the Genesis of Species Leibnitz was the first to propose the nebular hypothesis, which was more fully elaborated by Kant and Laplace. Lamarck, the Founder of Evolution His Life and Work It will be most convenient if we denominate the one party as that which holds to the communal or ‘nebular’ theory of authorship, and the other as the anti-communal or ‘artistic’ theory.

Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World 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 Such are a few of the many difficulties in the way of accepting the nebular hypothesis, as at present explained, as being the true mode of development of the solar system. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work I give this idea, in a nebular state, trusting that you will consolidate it. The Continental Monthly, Vol. 1, No. 5, May, 1862 Devoted To Literature And National Policy The telescope and the Copernican theory were as great achievements in their day as the spectroscope and the nebular hypothesis are in our day. A Wonderful Night; An Interpretation Of Christmas I cannot tell unless robed in the blandishments of plagiarism and the satellites of hygienic art as expunged by the gyrations of nebular hypothesis. Lippincott's Magazine of Popular Literature and Science Volume 15, No. 88, April, 1875 In the following year Mr. Roberts more than doubled for us the great extension of the nebular region which surrounds the trapezium in the constellation of Orion. Scientific American Supplement No. 819, September 12, 1891 The five great classes of facts that sustain the nebular hypothesis seem set before us to show the regular order of working. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work She found the nebular hypothesis, and hardly slept one night trying to comprehend it clearly enough to put it before others in a simple fashion. Brave Men and Women Their Struggles, Failures, And Triumphs According to the nebular hypothesis we may imagine that two or more dark suns, perhaps encircled with planets, have come into collision. A Trip to Venus And at these words the vast mass of congealed water rose majestically out of the ocean, and floated off into the nebular hypothesis. Punch, or the London Charivari, Volume 100, February 21, 1891 Indeed, we found some stars which might be regarded as not far advanced beyond the nebular condition. Scientific American Supplement No. 819, September 12, 1891 There are some difficulties in the way of the acceptance of the nebular hypothesis that compel many of the most thorough scientists of the day to withhold their assent to its entirety. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work He replies in a speech on the nebular hypothesis and all are very happy. Little Journeys to the Homes of the Great - Volume 01 Little Journeys to the Homes of Good Men and Great The remarkable discoveries that the spectroscope has enabled, and the facts learned from the physical history of comets and meteorites, can do no more than make what is known as the "nebular hypothesis" highly probable. Creation and Its Records Whatever purely literary talent existed was as yet in the nebular condition, a diffused luminous spot here and there, waiting to form centres of condensation. Ralph Waldo Emerson The old nebular hypothesis is discredited and the theory of the spiral movement of the solar matter seems to be confirmed by phenomena observable in the heavens. The Making of a Nation The Beginnings of Israel's History Whether, however, the nebular hypothesis lays down the road travelled to this transfiguration, we are not sure. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work And here is this crazy nephew of mine proposing the addition to the family of a stranger who hasn't any past and whose future seems wrapped mostly in a nebular hypothesis. Wild Wings A Romance of Youth In the nature of things, it would have been coeval with the introduction of the prima materies—at least if any nebular hypothesis can be relied on. Creation and Its Records It is vain to remind us how later Christianity has patronised nebular hypotheses and the The Nebular Hypothesis taken alone Involves Absurdity. doctrine of evolution. Pantheism, Its Story and Significance Religions Ancient and Modern Many of the nebular lines are due to hydrogen, others are due to helium; but the majority, including the two on the extreme right in Fig. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The nebular hypothesis has surveyed, worked, and perfected many long reaches of this road, but the rivers are not bridged, the chasms not filled, nor the mountains tunnelled. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work I had about deduced from certain astronomic phenomena I have had under minute observation during the past several tropic nights an entirely new nebular hypothesis which will unquestionably startle the scientific world. Return of Tarzan It is true that nebular matter, as now observed, is believed to be, partially at any rate, self-luminous. Creation and Its Records The colored planets and moons, the nebular masses and the cold, dead worlds lying in the silent morgue of eternity tell the wonderful story of cosmic grandeur. Editorials from the Hearst Newspapers By virtue of motions prevailing within the original nebular structure, or because of inrushing materials which strike the central masses, not centrally but obliquely, low rotations of the condensed nebulous masses will occur. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 He gave us the fundamental idea of what is called the nebular hypothesis. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work The opponents of the nebular hypothesis were overjoyed; they now sang paeans to astronomy, because, as they said, it had proved the truth of Scripture. History of the Warfare of Science with Theology in Christendom It must be, if the nebular hypothesis has any truth, older than our world; and long before this earth ceased to be molten, life upon its surface must have begun its course. The War of the Worlds We believe the splendid nebular construction of Laplace has its own difficulties; yet what noble or aspiring mind does not find interior warranties for the truth of that audacious synthesis? The Atlantic Monthly, Volume 05, No. 30, April, 1860 Although all recent novae have been observed to become planetary or stellar nebulae, they seem not to remain nebular for any length of time; they have gone further and become Wolf-Rayet stars. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 But any such rapid condensation of "vapory matter," in the light of Laplace's "nebular theory," is manifestly too absurd for scientific recognition. Life: Its True Genesis Again the nebular hypothesis came forth stronger than ever, and about 1850 the beautiful experiment of Plateau on the rotation of a fluid globe came in apparently to illustrate if not to confirm it. History of the Warfare of Science with Theology in Christendom As the Kant-Laplace nebular hypothesis has it, the rotating heavenly bodies separate themselves out from that vibrating primeval cloud. Monism as Connecting Religion and Science A Man of Science "Well, this nebular navigation beats all my experience," said Captain Arms, wiping the water out of his eyes. The Second Deluge This fact, coupled with Laplace's commanding position, caused the nebular hypothesis to be received with great favor. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 If the "nebular theory" of the universe be true, this is unquestionably the exact condition of things in the Milky-way. Life: Its True Genesis Even so determined a defender of orthodoxy as Mr. Gladstone at last acknowledged some form of a nebular hypothesis as probably true. History of the Warfare of Science with Theology in Christendom We are in the realm of chaos and chance, nebular, with phosphorescent gleams here and there, star stuff, but uncondensed in stars. Among My Books Second Series Barnard asserts that the “nebular hypothesis” would have been killed at its birth by a knowledge of these photographs. History of Astronomy In a few months or years the nebular lines diminish in brightness, and the continuous spectrum develops. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 In the nebular hypothesis, satellites are considered as masses thrown off from their primaries, exactly as the primaries had previously been from the sun. Vestiges of the Natural History of Creation Rougemont made the earth one of the "morning stars" of Job, reduced to chaos by Lucifer and his followers, and thence developed in accordance with the nebular hypothesis. History of the Warfare of Science with Theology in Christendom May not one discover in this old cosmogonic myth a dim hint of the nebular hypothesis of creation, as it is called? The Atlantic Monthly, Volume 03, No. 15, January, 1859 By establishing a 10-inch instrument at an altitude of 6,000 feet, Barnard has revealed the wide distribution of nebular matter in the constellation Scorpio over a space of 4° or 5° square. History of Astronomy In October Perrine and Ritchey discovered that the nebular structure had apparently moved outward from the nova, from September to October. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The nebular hypothesis almost necessarily supposes matter to have originally formed one mass. Vestiges of the Natural History of Creation Like Comte’s, it was based on science, and attempts to show how, starting with a nebular universe, the whole knowable world, psychical and social as well as physical, can be deduced. A History of Freedom of Thought You can demonstrate this for yourself by attempting to explain to someone an intricate conception such as the nebular hypothesis. How to Use Your Mind A Psychology of Study: Being a Manual for the Use of Students and Teachers in the Administration of Supervised Study It increased in brightness as it reached the densest part of the nebula, then it varied for some weeks by a couple of magnitudes, up and down, as if passing through separate nebular condensations. History of Astronomy The close relationship of the bright-line nebular spectrum, the bright-line stellar spectrum and the spectra of the simplest helium stars; the practically continuous sequence of spectra from the helium stars to the red stars. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 On some of the nebular lines, which are either straight throughout, or if they change direction do so at an angle, little stars are strung like beads. Curiosities of the Sky At the beginning of the nineteenth century Laplace worked out the mechanics of the universe, on the nebular hypothesis. A History of Freedom of Thought Laplace's nebular hypothesis is an attempt to give an adequate statement of the cosmic phase of evolution. Sociology and Modern Social Problems It showed no bright lines paired with the dark ones to indicate a train left behind; but in the end its own luminosity died out, and the nebular spectrum predominated. History of Astronomy I'm trying to solve a little nebular hypothesis of my own. Opening a Chestnut Burr Indeed, it is more true of the theory of gravitation, and of the nebular hypothesis, than of the hypothesis in question. Darwiniana; Essays and Reviews Pertaining to Darwinism With results as precious as when I examine the nebular theory and explain it to myself. Christian Science There are many other points also in which the nebular theory is known to tally with the facts of observation. Great Astronomers The nebular illumination as seen in photographs, taken from August to November, seemed to spread out slowly in a gradually increasing circle at the rate of 90” in forty-eight days. History of Astronomy This so-called "nebular hypothesis" assumes that in the beginning all space was uniformly filled with cosmic matter in a state of nebular or "fire-mist" diffusion, "formless and void." A History of Science — Volume 3 On the other hand, the theory of gravitation and its extension in the nebular hypothesis assume a universal and ultimate physical cause, from which the effects in Nature must necessarily have resulted. Darwiniana; Essays and Reviews Pertaining to Darwinism Here, then, we have nearly all the elements of the Daltonian theory of atoms on the one hand, and the nebular hypothesis of Laplace on the other. A History of Science — Volume 1 To incorporate all the several observations of nebular into one great systematic catalogue, seemed, therefore, to be an indispensable condition of progress in this branch of knowledge. Great Astronomers It had no sort of relation to the more modern, but equally misleading, “nebular hypothesis.” History of Astronomy Gravity eventually brings the nebular particles into closer aggregations, and increased collisions finally vaporize the entire mass, forming planetary nebulae and gaseous stars. A History of Science — Volume 3 Perhaps scarcely any philosophical objection can be urged against the former to which the nebular hypothesis is not equally exposed. Darwiniana; Essays and Reviews Pertaining to Darwinism He is best known for his theory of the formation of the planetary systems, the so-called "nebular hypothesis." Autobiography and Selected Essays It was asserted by those who were indisposed to accept the nebular hypothesis, that the non-resolution was due to imperfection in the telescopes used. History of the Conflict Between Religion and Science The most famous answer to this question is the "nebular hypothesis." The Story of Evolution His theory, known as the "meteoric hypothesis," probably bears the same relation to the speculative thought of our time that the nebular hypothesis of Laplace bore to that of the eighteenth century. A History of Science — Volume 3 It is a more or less imperfectly condensed star, surrounded by nebular masses. The Story of Evolution Whatever the nature of these diffused stretches of matter may be, then, the name applies fitly to them, and any theory of the development of a star from them is still a "nebular hypothesis." The Story of Evolution In such a nebular mass, cooling by radiation is a necessary incident, and condensation and rotation the inevitable results. History of the Conflict Between Religion and Science That is the genealogy of the famous nebular hypothesis. The Story of Evolution The nebular hypothesis thus given detailed completion by Laplace is a worthy complement of the grand cosmologic scheme of Herschel. A History of Science — Volume 3 There is a widespread idea that these difficulties have proved fatal to the old nebular hypothesis, and there are distinguished astronomers who think so. The Story of Evolution Its features are what we should expect on the nebular hypothesis. The Story of Evolution On the lines of the generally received nebular hypothesis this can easily be imagined, in broad outline. The Story of Evolution In the first place, their mere existence has provided a solid basis for the nebular hypothesis, and their spiral form irresistibly suggests that they are whirling round on their central axis and concentrating. The Story of Evolution This contention had the theoretical support of the nebular hypothesis, then gaining ground, which supposed the earth to be a cooling globe. A History of Science — Volume 3 |
