"Prism" Quotes from Famous Books



... warmth, and for a little space his level rays shoot out and gild the tree tops and the distant hills. The snow springs to life. Dead white no longer, its dry, crystalline particles glitter in myriads of diamond facets with every colour of the prism. Then the sun is gone, and the lovely circle of rose pink over amethyst again stretches round the horizon, slowly fading until once more the pale primrose glows in the south against the purple sky with its silver stars. Thus sunrise and sunset form a continuous ...

... spheres which the ancients imagined to be entered only through a gate of ivory, to be surrounded by pilasters of diamond, and surmounted by a dome arched with fawn-colored crystal, upon which played the various dyes of the prism; spheres, like the Mexican opal, whose kaleidoscopical foci are dimmed by olive-colored mists veiling and unveiling the inner glories; spheres, in which all is magical and supernatural, reminding us of the marvellous ...

... the rear guard of the animals raced madly away for about seventy yards, whirled in a phalanx, and gazed back. Neither man moved. Simba continued to stare, and Kingozi had lifted his prism glasses. A tyro would have attempted to draw near for a finishing shot, and so would probably have been let in for a long chase. A freshly wounded animal, if kept moving, is capable of astonishing endurance. But these two knew better than that. In a very few minutes the zebra, without ...

... fitting tools and measures, would find it very difficult to make cells of wax of the true form, though this is effected by a crowd of bees, working in a dark room. Each cell, as is well known, is a hexagonal prism, with the basal edges of its six sides, beveled so as to join an inverted pyramid of three rhombs. These rhombs have certain angles, and the three which form the pyramidal base of a single cell on one side of the ...

... heat! We'll run 'em down if we can only keep going," Wayland had said; as they set out again in the blistering wind; but to his dying day, he will never forget the traverse of the Desert in that mid-day sun. To his dying day he will never see the spectrum colors of white light split by a prism, or the spectrum colors of a child's soap bubble, without living over the tortures of that afternoon, for the air, whipped to dust by the hurricane wind, acted as a prism splitting the white flame of light to lurid reds and ...

But even if the feelings of affection and gratitude that he inspired in me did come like a prism and interpose themselves between my eyes and his face, I do not see anything greatly to be regretted in it.[134] I had not yet felt the charm of his personal fascination, I had neither heard nor seen him, and I did not owe him anything at all, when my interest was gripped in reading his ...

It can see as far as a man with prism binoculars. All the odds are in the animal's favor except two—its fatal desire to run in a circle about the pursuer, and the use of a high-power rifle. But even then an antelope three hundred yards away, going at a speed of fifty miles an hour, ...

She felt, but without comprehending, a gulf between them; then she turned away her head and wept. Suddenly a strong hand seized her by the waist, and a soft voice said to her: "Come!" She obeyed, resting her ...

After passing through a pyramidal room, with triangular sides that sloped to a point, she came to one in the shape of a polygonal prism. In a long, broad corridor she had to walk on a narrow path, bordered by sphinxes; and there she clung tightly to her guide, for on one side of the foot-way yawned a gulf of great depth. In another place she heard, above her head, the sound of ...

A handful of ashes crowned its top. Between the altar and the wall intervened a space of ...

The crystals from Anglesey, which were formerly found abundantly on a matrix of dull limonite, are small in size and simple in form, being usually bounded by four faces of a prism and four faces of a dome; they are brownish-yellow in colour owing to a stain of limonite. Crystals from some other localities, notably from Monteponi in Sardinia, are transparent and colourless, possessed of a brilliant adamantine lustre, and usually modified by numerous ...

And, in the condition supposed, the mind becomes a prism to sophisticate and falsify the light of truth into striking and brilliant colours, instead of being a clear and perfect lens to concentrate that light in its natural whiteness and purity.

... intellectual passions correspond to the other three notes of the musical scale and to three other prismatic colors; and the five sensitive passions correspond to the five semi-tones, and also to five intermediate colors of the prism. Now this at first sight looks very much like a scheme or a notion, but the founder of this doctrine lays his claim to a higher judgment.

All his colors are tropical in depth and intensity. With every quick motion the tints change as in a prism, and each tint is more splendid than the last; green more beautiful than any green, except that of a duck's neck; brown infiltrated with gold, and ranging through the whole gamut of its possibilities.

At one end of the spectrum are the long waves (wave-length 760 millionths of a millimeter), ...

... the spectral colours, when these are produced by a diffraction grating, invalidate Newton's idea that the optical apparatus serves to reveal colours which are inherent in the original light. Today it is known that these colours are an outcome of the interference of the apparatus (whether prism or grating) with the light. Thus we find Professor R. W. Wood, in the opening chapter of his Physical Optics, after having described the historical significance of Newton's conception of the relation between light and colour, saying: ...

Unlike electricity, however, it may be converted into many different forms by fields of force, in a way comparable to that in which white light is resolved into colors by a prism—or rather, more like the way alternating current is changed to direct current by a motor-generator set, with attendant changes in properties. There is a complete spectrum of more than five hundred factors, each as different from the others as red ...

The sun's rays hit the surface of the waves at a fairly oblique angle, decomposing by refraction as though passing through a prism; and when this light came in contact with flowers, rocks, buds, seashells, and polyps, the edges of these objects were shaded with all seven hues of the solar spectrum.

Grasping one of them in his hand, he wrenched it from the branch; but as he did so, the husk dropped off, and the prism-shaped nuts fell like a shower of huge hailstones on the roof of the toldo. "Monkey-pots they're called," continued he, referring to the empty pericarp still in his hand. "That's the name by which the Indians know them; because ...

He supposes a cloud between the sun and observer, and that through some opening in that cloud, the rays pass, and form an iris on the opposite part of the heavens, just as a ray passing through a hole in the shutter of a darkened room, and falling on a prism there, forms the prismatic colors on the opposite wall. According to this, we might see bows of more than the half circle, as often as of less. A thousand other objections occur to this hypothesis, which need not be suggested to you. The result is, that we are wiser than we were, ...

We find Tintoret passing like a fire-fly from light to darkness in one oscillation, ranging from the fullest prism of solar color to the coldest grays of twilight, and from the silver tingeing of a morning cloud to the lava fire of a volcano: one moment shutting himself into obscure chambers of imagery, the next plunged into the revolutionless day of heaven, and piercing space, deeper than the mind can ...

Having contrived an "astrometer" in which an "artificial star," formed by the total reflection of moonlight from the base of a prism, served as a standard of comparison, he was able to estimate the lustre of the natural stars examined by the distances at which the artificial object appeared equal respectively to each. He thus constructed a table of 191 of the principal stars,[127] both in ...
