The Sailor's Word-Book An Alphabetical Digest of Nautical Terms, including Some More Especially Military and Scientific, but Useful to Seamen; as well as Archaisms of Early Voyagers, etc. A very slender ring, taking off just the equatorial surface, will be hoop-shaped; while a tolerably massive ring, trenching appreciably on the diameter of the spheroid, will be quoit-shaped. Essays: Scientific, Political, & Speculative, Vol. I Its shape is not absolutely spherical, but spheroid—that is, flattened at the poles. Astronomy for Amateurs Further, the process of condensation would assume a spherical form, as the conception of our aetherial atom is that of a sphere or an oblate spheroid. Aether and Gravitation In a short while, we had cut the huge spheroids into slices, which we chewed with avidity. The Desert Home The Adventures of a Lost Family in the Wilderness He hadn’t the slightest notion what it was that he was waiting for, but he was as certain of its coming as he was of the fact that the Earth was an oblate spheroid. Unwise Child And while the density of the spheroid continues small, fluid friction will scarcely at all change these differences. Essays: Scientific, Political, & Speculative, Vol. I They were piled in colorful disorder, red, purple, orange and yellow, pear-shaped, egg-shaped, and clustered spheroids—fantastic, unearthly. Pygmalion's Spectacles Oblate: flattened; applied to a spheroid of which the diameter is shortened at two opposite ends. Explanation of Terms Used in Entomology But sweat glistened on the dark young face, broke free and drifted in tiny spheroids toward the ventilator. The Burning Bridge Whether a product of workmanship like human workmanship or not, this object is described as an oblate spheroid, about two inches across its major diameter. The Book of the Damned Now this conclusion assumes, like that of M. Babinet, that all parts of the nebulous spheroid had equal angular velocities. Essays: Scientific, Political, & Speculative, Vol. I The internal tendency of an organism to certain considerable and definite changes would correspond to the facets on the surface of the spheroid.

New Word-Analysis Or, School Etymology of English Derivative Words And then fate again favored Yale, for a little puff of wind carried the spheroid just inside the posts and over the bar. Andy at Yale Or, The Great Quadrangle Mystery In spite of all the learned theories of Professor Hardwigg, a fierce and vehement fire certainly burned within the entrails of the great spheroid. A Journey to the Centre of the Earth The usual idea is that a vast rotating nebulous spheroid arises before there are produced any of the planet-forming rings. Essays: Scientific, Political, & Speculative, Vol. I The correction previously noticed is on the supposition that the earth is like a sphere having TF for radius; as it is a spheroid, we must correct again. Outlines of a Mechanical Theory of Storms Containing the True Law of Lunar Influence In one case it is water which escapes, in the other heat; but in both contraction of the part which suffers the loss leads to the folding of the outside of the spheroid. Outlines of the Earth's History A Popular Study in Physiography Archimedes developed the proportions necessary for effecting this comparison, in his treatises on the sphere and cylinder, the spheroid and conoid, and in his work on the measure of the circle. Anecdotes of Painters, Engravers, Sculptors and Architects and Curiosities of Art (Vol. 3 of 3) The most renowned juggler of the spheroid in the world! The Mystery at Putnam Hall The School Chums' Strange Discovery While the force of gravitation draws all the atoms of the spheroid together, their tangential momentum is resolvable into two parts, of which one resists gravitation. Essays: Scientific, Political, & Speculative, Vol. I The object, Fry told newsmen, was an "ovate spheroid about thirty feet at the equator." The Report on Unidentified Flying Objects The old geographies used to state that the earth is an oblate spheroid, then explain that term by comparison with an orange, pointing out the essential flattening at the poles. Public Speaking Laplace, in fact, has shown that the attraction of the earth introduces into the rotatory motion of the lunar spheroid the secular inequalities which exist in the movement of revolution. Biographies of Distinguished Scientific Men There are likewise three nuts in one husk, forming in shape an oblong spheroid. The History of Sumatra Containing An Account Of The Government, Laws, Customs And Manners Of The Native Inhabitants Now in fluid spheroids—gaseous, or liquid, or mixed—increasing size entails an increasing obstacle to cooling, consequent on the increasing distances to be travelled by the circulating currents. Essays: Scientific, Political, & Speculative, Vol. I They are not perfectly round but either slightly flattened at the poles into an "oblate spheroid" or made into an oval something like a modern football. Outdoor Sports and Games At the flat end of the spheroid was a small ring of a pink colour, from which ran lines forming the ribs, which supported the sides of the animal. Journals of Two Expeditions of Discovery in North-West and Western Australia, Volume 2 Do the extremities of the axis around which the earth performs an entire revolution once in every twenty-four hours, correspond always to the same material points of the terrestrial spheroid?

Essays: Scientific, Political, & Speculative, Vol. I But, for the present, without yet deciding one or other, we will consider these spheroids only in those sections of them which make ellipses in the plane of this figure. Treatise on Light An elliptical spheroid of revolution gives evidence of having once been a soft or fluid mass. COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1 The great geometer has demonstrated that no circumstance depending on universal gravitation can sensibly displace the poles of the earth's axis relatively to the surface of the terrestrial spheroid. Biographies of Distinguished Scientific Men That, unaided, it can neither account for every spheroid oblate, nor explain away such evident difficulties as are presented by the relative density of some planets. Five Years of Theosophy The Earth's molten nucleus tends ever, with enormous force, to assume the form of a regular oblate spheroid. Essays: Scientific, Political, & Speculative, Vol. I Inquiring subsequently what might be the position and form of these spheroids in the crystal, I considered that all the six faces produced precisely the same refractions. Treatise on Light It was Tom's luck to capture the yellow spheroid as it descended, and, well protected by interference, he raced down the field. Tom Fairfield's Pluck and Luck Limits of the obliquity of the ecliptic modified by the action of the sun and moon upon the terrestrial spheroid.—The ecliptic will not continue indefinitely to approach the equator.

The Certainty of a Future Life in Mars What are the corollaries in relation to concentrating nebulous spheroids? Essays: Scientific, Political, & Speculative, Vol. I I say axis or major diameter, because the same ellipse SVT may be considered as the section of a spheroid of which the axis is AZ perpendicular to AV. Treatise on Light Motion produces the spheroid, and the rotation of the spheroid produces atmosphere and diversity of surface; all these variations characterize the spirit globe. Strange Visitors In order, then, that one of those spheroids might absorb all the others belonging to the same ring, it will be sufficient to assign to it a mass greater than that of any other spheroid. Biographies of Distinguished Scientific Men The egg is an elongated oval, compressed almost throughout its entire length, very blunt at both points; a long cone, the apex broadly truncated and rounded off obtusely, sealed on half a very oblate spheroid. The Nests and Eggs of Indian Birds, Volume 1 But now suppose that instead of such a spheroid, we assume one of, say, twenty or thirty times the mass; what will then happen? Essays: Scientific, Political, & Speculative, Vol. I Let the line N be the length of the travel of light in air during the time in which, within the crystal, it makes, from the centre C, the spheroid QCqgM. Treatise on Light What kind of spectacle would her hidden hemisphere present to our terrestrial spheroid? The Moon-Voyage We would thus have a spheroid of water, with granite rocks and islands scattered here and there. Theory of the Earth, Volume 1 (of 4) Some are oblate spheroids with the aperture near the top, some are purse-like and suspended, and some are regular cups. The Nests and Eggs of Indian Birds, Volume 1 And she pointed to an oblate spheroid, the colour of brick, but smoother, which lay on a plate near the gas-stove. Helen with the High Hand (2nd ed.) Now this point is necessarily the point I which is sought, since the plane drawn through TK can touch the spheroid at one point only. Treatise on Light It may also be noticed that upon the lunar spheroid the South Pole is much more continental than the North Pole. The Moon-Voyage It took humanity untold thousands of years to learn the scientific truth that the earth is an oblate spheroid. Analyzing Character We owe to him the discovery of the true shape of the "red planet Mars,"—that, like the Earth, it is an oblate spheroid, or flattened at the poles. The Story of the Herschels Well and happy; I do not believe it falls to the lot of any old woman to be happier in this oblate spheroid. Fated to Be Free When one has a number of spheroids of the form above described, and ranges them in a pyramid, one sees why the two methods of division are more difficult. Treatise on Light Do not frighten yourself," answered Barbicane, "Our spheroid is at her post, but we cannot see her from this side. The Moon-Voyage He showed that the earth must be an oblate spheroid, formed by the revolution of an ellipse round its lesser axis. The World's Greatest Books — Volume 09 — Lives and Letters Or again: the French Commissioners proved by actual measurement that the earth is an oblate spheroid, of which Newton had convinced himself a priori. Phases of Faith Passages from the History of My Creed Now, as the world is a globe, or, to speak more accurately, an oblate spheroid, the attempt to make an oblong square its symbol would seem, at first view, to present insuperable difficulties. The Symbolism of Freemasonry The oblate spheroid assumed an archipelagic formation, melting into irregularly-placed military islands upon a sea of dust. Driftwood Spars The Stories of a Man, a Boy, a Woman, and Certain Other People Who Strangely Met Upon the Sea of Life They were rings of clouds placed concentrically round the terrestrial spheroid. The Moon-Voyage A few thousand tons of it would burst our spheroid and scatter the fragments into space. Facing the Flag To the best of present-day knowledge the stars are in a spheroid whose longer axes are coincident with the plane of the Milky Way. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 What kind of spectacle would its hidden hemisphere present to our terrestrial spheroid?

Driftwood Spars The Stories of a Man, a Boy, a Woman, and Certain Other People Who Strangely Met Upon the Sea of Life My friends," said he, "it is twenty minutes past ten; at thirteen minutes to eleven Murchison will set fire to the Columbiad; at that minute precisely we shall leave our spheroid. The Moon-Voyage The object proved to be a black, wrinkled spheroid, baked hard as iron in the sunshine of Estrella's toys, a potato squeezed to dryness by the constricting power of the rawhide. Arizona Nights Morton mentions a patient of forty-seven, who was injured in a railroad accident near Phoenixville, Pa.; there was a compound comminuted fracture of the skull involving the left temporal, spheroid, and superior maxillary bones. Anomalies and Curiosities of Medicine At that precise moment we shall leave our spheroid. From the Earth to the Moon; and, Round the Moon They consist of oblate spheroids and are found in many parts of the earth totally detached from the beds in which they lie, as at East Lothian in Scotland. The Botanic Garden A Poem in Two Parts. Part 1: the Economy of Vegetation In a word, there is no moon, applying that qualification to our spheroid, except for one side of the disc. The Moon-Voyage It is best to be as comfortable as possible under any circumstances, so De Plonville sat down on the spheroid and let his feet dangle toward the water. The Face and the Mask How he had sprinted—back—back—and at the last second, reached high in the air, grabbing the soaring spheroid, and saving the game for his Alma Mater! T. Haviland Hicks Senior But the cylinder = 3 $\\times$ cone, hence 3 $\\times$ cone = 2 $\\times$ cone + 2 $\\times$ spheroid. Geometrical Solutions Derived from Mechanics; a Treatise of Archimedes Finally Miss Thorne walked over to the long table and curiously lifted one of the spheroids. Elusive Isabel Human beings who had left the terrestrial spheroid, who had returned after their strange journey into celestial space, could not fail to be received like the prophet Elijah when he returned to the earth. The Moon-Voyage He wears the usual youth's garment, the short toga, reaching below the knee, and a hollow spheroid of gold suspended round his neck. De La Salle Fifth Reader The truth is, the paralyzed youth was too petrified by fear to dodge, and that before he could avoid it, the speeding spheroid crashed against his noble brow with a sickening impact. T. Haviland Hicks Senior Subtract 2 $\\times$ cone from both sides; then a cone whose axes form the triangle $\\alpha\\epsilon\\zeta$ = 2 $\\times$ spheroid. Geometrical Solutions Derived from Mechanics; a Treatise of Archimedes All were taken in by this idea, so ingenious and simple, of modifying the axis on which this earthly spheroid is rotating. Topsy-Turvy It is my belief—to return to less fanciful hypotheses—that the Antarctic region, with a superficies of more than five millions of square miles, has remained what our spheroid was during the glacial period. An Antarctic Mystery Like mad the whole twenty-two players darted for the yellow spheroid. The Boys of Columbia High on the Gridiron : or, the Struggle for the Silver Cup A fowl weighing seven pounds, stuffed with truffles, so that it has become a spheroid. The Physiology of Taste Therefore $\\theta\\alpha : \\alpha\\kappa =$ cylinder $:$ spheroid $+$ cone. Geometrical Solutions Derived from Mechanics; a Treatise of Archimedes Because this movement modifies the direction of the axis of our spheroid,” observed another correspondent. Topsy-Turvy But it was also, he says, a centre of contraction, produced by the same cooling, the globular form, therefore, of such spheroids being the combined result of crystallisation and contraction. The Student's Elements of Geology Into his arms, with a resounding "pung!" the spheroid landed, and, like a flash, the quarter passed it to Jack Comfort for a return kick. The Boys of Columbia High on the Gridiron : or, the Struggle for the Silver Cup Notwithstanding the theories of Professor Liedenbrock, a violent heat did at that time brood within the body of the spheroid. A Journey to the Interior of the Earth The lava where first met with is 130 feet in thickness: it there consists of two, three, or perhaps more streams, divided from each other by vesicular spheroids like those on the surface. Geological Observations on South America He thus obtained a spheroid, the capacity of which amounted, in round numbers, to ninety thousand cubic feet. Five Weeks in a Balloon According to M. Delesse, the centre of each spheroid has been a centre of crystallisation, around which the different minerals of the rock arranged themselves symmetrically during the process of cooling. The Student's Elements of Geology Material minds might think that gravitation," Quoth Grey, "drew yon metallic spheroid down. Complete Poetical Works As the shrinkage and corresponding increase of density proceed, the planetary spheroid becomes more and more elliptic, and the succession of forms constitutes a family classified according to the density of the liquid. Darwin and Modern Science These masses would take a spheroid form with a rotatory movement in the direction of the revolution, because their inner molecules had less velocity than the outer. A History of Science — Volume 3 During the geological epoch, when the terrestrial spheroid was still in course of formation, a thick atmosphere surrounded it, saturated with watery vapors, and copiously impregnated with carbonic acid. The Underground City, or, the Child of the Cavern Whence came it that a new blazing spheroid, hitherto unknown to astronomy, now appeared suddenly in the firmament, though it were but to lose itself immediately behind masses of accumulated cloud? Off on a Comet! a Journey through Planetary Space Perhaps then, our spheroid will rest—will be left to death—to revive some day under superior conditions! The Mysterious Island We have then a planetary spheroid, rotating slowly, slightly flattened at the poles, with a high degree of stability, and possessing a certain amount of rotational momentum. Darwin and Modern Science The circular cylinders are exactly analogous with our planetary spheroids, and the elliptic ones with the Jacobian ellipsoids. Darwin and Modern Science |
