"Luminosity" Quotes from Famous Books
 ... really exhibited the dimensions assigned to it, the probability is that it was not a gem at all, but one of those counterfeits of glass, in producing which STRABO relates that the artists of Alexandria attained the highest possible perfection (1. xvi. c. 2. sec. 25). Its luminosity by night is of course a fiction, unless, indeed, like the emerald pillar in the temple of Hercules at Tyre, which HERODOTUS describes as "shining brightly by night," it was a hollow cylinder into which a lamp could be introduced. ...

... 'self-luminous', and that as a planet, besides the light which it receives from the central body, the Sun, it shows itself capable in itself of developing light. The intensity of the terrestrial light, or, rather the luminosity which is diffused, exceeds, in cases of the brightest colored radiation toward the zenith, the light of the Moon in its first quarter. Occasionally, as on the 7th of January, 1831, printed characters could be read without difficulty. This almost uninterrupted development of light p 202 in the ...

... into no line of evolution whatever, and was as wonderful to the student of Gothic architecture in the twelfth century, as to the student of the dynamo in the twentieth. Studied in the dry light of conservative Christian anarchy, Russia became luminous like the salt of radium; but with a negative luminosity as though she were a substance whose energies had been sucked out — an inert residuum — with movement of pure inertia. From the car window one seemed to float past undulations of nomad life — herders deserted by their leaders and ...

... hydrocarbons seems therefore to be a retrograde step, useful undoubtedly in certain cases, as in the Bunsen flame of the laboratory, but not the ideal method of combustion. The ideal method looks to the use of a very rich gas, and the burning of it with a maximum of luminosity. The hot products of combustion must give up their heat by contact. It is for them that cross tubes in boilers are useful. They have no combustion to be interfered with by cold contacts. The flame ...

... and more distasteful, until he found that he was actually writing against the grain. He threw this aside impatiently, and with extraordinary energy and enthusiasm began a new story, Weir of Hermiston, which would undoubtedly have been his masterpiece, had he lived to complete it. In luminosity of style, in nobleness of conception, in the almost infallible choice of words, this astonishing fragment easily takes first place in Stevenson's productions. At the end of a day spent in almost feverish dictation, the third of December 1894, he suddenly fainted, ...

It was not exactly dark, though in this part of the city there is neither gas nor electricity, and on such a night as this neither moon nor stars dared show their faces in so gray a sky; but a sort of all-diffused luminosity was in the air, as though the sea of atmosphere was charged with an ...

The ordinary research paper, when it is not extravagant theorizing, is apt to be rather sawdusty in texture, and Ann Veronica was delighted to find the same easy and confident luminosity that distinguished his work for the general reader.

... pole, in the form of a disk, at each end, both coated with a paint of phosphorescent yttria. As the rarefaction approaches about 0.5 millimeter the surface of the negative pole, A, becomes faintly phosphorescent. On continuing the exhaustion this luminosity rapidly diminishes, not only in intensity but in extent, contracting more and more from the edge of the disk, until ultimately it is visible only as a bright spot in the center. This fact does not prop a recent theory, that as the exhaustion gets higher the discharge leaves the center ...

... and flowers we get something near the actual colour, but the depth, the clearness, the luminosity, and the vast extent are all wanting, and these are all essential features of the sunset's glories. So we must imagine all these colours glowing with light and never still—perpetually changing from one to the other and shading off from one into the other, one colour ...

The window-lights are all extinguished. The few lights on the great boulevards are so dimmed that their luminosity is about that of a healthy firefly in June back home. One gropes his way about, feeling ahead of him and navigating cautiously, even ...

One of their ships—then another—and another fell victim to a pale red ray that showed up like a ghostly pillar of luminosity coming from nowhere and going nowhere! The answer? The invaders' ships were becoming invisible! The invisibility detectors were being overloaded now, and the hunt was hard, while the Nigrans were slipping past ...

... name heaven is applied to a body that participates in any property of the heavenly body, as sublimity and luminosity, actual or potential. Thus Damascene (De Fide Orth. ii) holds as one heaven all the space between the waters and the moon's orb, calling it the aerial. According to him, then, there are three heavens, the aerial, the starry, and one higher than both these, of which the Apostle is understood to ...

... to work this perhaps somewhat fanciful analogy to death, or pretend it is anything more than a convenient metaphor. Still, taken as such, it is not without its luminosity. For a metaphor, by supplying us with a picturable representation, often enables us really to get at the hang of the thing a vast deal better than the most solemn argument. And I fancy communities sometimes ...

The disk itself has in the mean time enlarged into a series of concentric bright rings, graduated in luminosity with beautiful precision from center toward circumference. The outermost ring is considerably brighter, however, than it would be if the same gradation applied to it as applies to the inner rings, and it is surrounded, moreover, on its outer edge by a slight flare which tends ...

There, on those vast plains, they were to describe enormous geometric figures, drawn in characters of reflecting luminosity, among which was the proposition regarding the 'square of the hypothenuse,' commonly called the 'Ass's Bridge' by the French. 'Every intelligent being,' said the geometrician, 'must understand the scientific meaning of that figure. The ...

Recently, however, that has been widely replaced by use of a Bunsen flame upon an incandescent mantle, such as the Welsbach. The principle of the incandescent mantle is very simple. When certain substances, such as thorium and cerium, ...

It was like the insanely enlarging head of a newborn comet, whose tail would be formed presently by light-pressure. The Plumie ship was almost ...

... been said before, is peculiarly his own. It is true that in the earlier pictures the influence of Claude Lorraine is evident; but upon this root is engrafted an audacity in the conception of color, a research of luminosity in comparison with which nearly all painting is eclipsed. That this refulgence is tinged now and then with exaggeration, with a forcing of effect that destroys the sense of weight and solidity in depicted objects where this sense should prevail, is ...

As they approached the farther side and the sunlight decreased, they found that a diffused luminosity pervaded everything. It was sufficiently bright to enable them to see the dark side of the meteoric masses, and, on emerging from the nucleus in total darkness, they found the shadow stretching thousands of miles before them into space.

The twilight had settled into a night that was moonless, but had that luminosity often seen on clear nights in late autumn. He could see all about him, even in the wood.

Its brightness is much greater in some places than in others; the central parts are, generally speaking, the most brilliant, and the luminosity gradually fades away as the edge of the nebula is approached. In fact, we can hardly say that the nebula has any definite boundary, for with each increase of telescopic power faint new branches can be seen. There seems ...

A star shed its radiance over his cradle—symbol and prophecy of his mission. As he grew in years he grew in luminosity until he lighted up Palestine and shot some rays across the borders of that little land into the great world.

What remained with him, perhaps, most vividly, he says, was the quality of the big blue eyes, their luminosity, their far-seeing expression, their kindliness. They were the eyes of the true visionary, but in such a personality they proclaimed the mystic who had retained his health of soul and body. Mr. Skale was ...

While passing through the cloud the forward face of the star is bombarded at high velocities by the resisting materials. The surface strata become heated, the luminosity of the star increases rapidly. The effect of the bombardment by small particles can be only skin deep, and the brightness of the star should diminish rapidly and therefore the spectrum change speedily from one type to another.
