More "Parallax" Quotes from Famous Books
 ... refraction of the solar rays that must be produced by the Earth's atmosphere. It is easy to show that this refraction prevents the Sun from ever being totally invisible. See here!" he continued, pulling out his tablets, "Let a represent the horizontal parallax, and b the half of the Sun's ...

... position around the sun, and the moon as a satellite of the earth. He retained the old conception of the primum mobile or sphere of fixed stars though he placed it at an infinitely greater distance than did the ancients, to account for the absence of any observed alteration (parallax) in the position of the stars during the year. He also retained the old conception of circular orbits for the planets, though at one time he considered the possibility of their being elliptical, as they are. Unfortunately for his immediate followers the section on this subject ...

... cluster of stars, to which our cosmical island belongs, forms a lens-shaped, flattened stratum, detached on every side, whose major axis is estimated at seven or eight hundred, and its minor one at a hundred and fifty times the distance of Sirius. It would appear, on the supposition that the parallax of Sirius is not greater than that accurately determined for the brightest star in the Centaur (0".9128), that light traverses one distance of Sirius in three years, while it also follows, from Bessel's earlier excellent Memoir* on the parallax of the remarkable star 61 Cygni (0".3483), ...

... world of ours a pretty big world," Gershom was saying. "But look at Betelgeuse up there, which Michelson has been able to measure. He has, at least, succeeded in measuring the angle at the eye that Betelgeuse subtends, so that after estimating its parallax as given by a heliometer, it's merely a matter of trigonometry to work out the size of the star. And he estimated Betelgeuse to be two hundred and sixty million miles in diameter. That means it would take twenty-seven million of our suns ...

... toward a center. The probable fact that the stars constituting the cluster are very much smaller than our sun might be regarded as favoring the hypothesis of an explosion. Of their real size we know nothing, but, on the basis of an uncertain estimate of their parallax, it has been calculated that they may average forty-five thousand miles in diameter — something more than half the diameter of the planet Jupiter. Assuming the same mean density, fourteen thousand such stars might have been ...

... perceived that instead of one there are two concentric rings separated by a dark space. He also discovered four of the planet's satellites—viz. Japetus, Rhea, Dione, and Tethys. He made a near approximation to the solar parallax by means of researches on the parallax of Mars, and investigated some irregularities of the Moon's motion. Cassini discovered the belts of Jupiter, and also the Zodiacal Light, and established the coincidence of the nodes of the lunar equator ...

... any Calvinistic covenant, but of an innumerable multitude of ennobled, purified, and expanded beings, convoked from every satellite and planet, every sun and star, and overflowing with gratitude and love to that universal Father of lights, with whom is no parallax, nor descension, and who kindled every spark of life and beauty that in their individual and combined lustre He might reflect and repeat His ...

... of space besides that form of tridimensional space in which our Activity is involved. For such, a different geometry may and will be applicable; but for the tridimensional conditions of our activity the proposition is necessary and absolute. No measurement of any stellar parallax, however minute and whatever the result might be, could have any bearing on its truth. Geometry is the science of the pure forms of our ...

... bewildering revelations of his telescope have been since questioned, the vast progress which has been made in sidereal astronomy, to which, as I understand, the Dudley Observatory will be particularly devoted, the discovery of the parallax of the fixed stars, the investigation of the interior relations of binary and triple systems of stars, the theories for the explanation of the extraordinary, not to say fantastic, shapes discerned in some of the ...

... A star-picture along the ecliptic. An hour's run on interplanetary drive—no overdrive field in use. Another picture. The two prints had only to be compared with a blinker for planets to stick out like sore thumbs, as contrasted with stars that showed no parallax. Sirene I—the innermost planet—was plainly close to a transit. II was away on the far side of its orbit. III was also on the far side. IV was in quadrature. There was the usual gap where V should have been. VI—it didn't ...

... a lens-shaped, flattened, and everywhere detached stratum, whose major axis is estimated at seven or eight hundred, and its minor axis at a hundred and fifty times, the distance of Sirius. If we assume that the parallax of Sirius does not exceed that accurately determined for the brightest stars in Centaur (0.9128 sec.), it will follow that light traverses one distance of Sirius in three years, while nine years and a quarter are required ...

... that room, you know, is half-way between the ground-floor and first floor. Still, sound does travel so! We must betake ourselves to measurement, I fear.—But another thing came into my head last night which may serve to give us a sort of parallax. You said you heard the music in your own room: would you let me look about in it a little? something might suggest itself!—Is it the room I saw you ...

... separately. If you hold up a finger and look at it, with each eye separately, you will see that the finger is projected by each eye on to a different part of the background; the angle which the lines of sight, from each eye, make when they meet at the object, is called the angle of parallax, and the further the object is away the smaller that angle becomes; it is, in fact, the angle subtended, at the object, by the distance between the two eyes. As the object is brought nearer the eyes have ...

... the sun's apogee as well as its mean motion. Their calculations on the eccentricity of the moon prove that they had a rectilinear trigonometry and tables of chords. They had an approximate knowledge of parallax; they could calculate eclipses of the moon, and use them for the correction of their lunar tables. They understood spherical trigonometry, and determined the motions of the sun and moon, involving an accurate definition ...

... safely presume to be in proportion to their actual size and the distance at which they are placed from us. Attempts have been made to ascertain the distance of some of the stars by calculations founded on parallax, it being previously understood that, if a parallax of so much as one second, or the 3600th of a degree, could be ascertained in any one instance, the distance might be assumed in that instance as not less than 19,200 millions of miles! In the case of the most brilliant ...

... a moment too soon, for, as if the previous proofs had not been sufficient, each of the motions of the earth was now absolutely demonstrated anew, so as to be recognised by the ordinary observer. The parallax of fixed stars, shown by Bessel as well as other noted astronomers in 1838, clinched forever the doctrine of the revolution of the earth around the sun, and in 1851 the great experiment of Foucault with the pendulum showed to the human eye the earth in motion around its own axis. To make ...
