"Luminosity" Quotes from Famous Books
 ... adequate, is very costly. Tests specially carried out by one of the authors to determine some of the figures required in the ensuing table show that ordinary paraffin or "wax" candles usually emit about 20 per cent. more light than that given by the standard spermaceti candle, whose luminosity is the unit by which the intensity of other lights is reckoned in Great Britain; and also that the light so emitted by domestic candles is practically unaffected by the sizes—"sixes," "eights," or "twelves"—burnt. ...

... familiar with the idea that as a person progresses on the upward path his causal body, which is the determining limit of his aura, distinctly increases in size as well as in luminosity and purity of colour. Many of us know from experience that the aura of a pupil who has already made considerable advance on the Path is very much larger than that of one who is but just setting his ...

With it had come that strange quality of visibility that seems to appertain to a sheeted world like an inherent luminosity; or was it perchance some vague diffusion of light from the clouded moon, skulking affrighted somewhere in the grim and sullen purlieus of the sky? She listened, thinking to hear the stir of horses in their stalls, ...

... and he says that only in Florida has he seen anything to compare with the beauty of Hili-li vegetation in October and November. I should imagine from what he says that the coloring of vegetation is in great part the merest tintage, the large admixture of white giving to it a startling luminosity, and permitting the fullest effect of those neutral tints which are capable of combinations at once so restful and so pleasing to the refined eye. In the vegetation of Florida there is luminosity; but chromatic depth, as in most tropical coloring, is the chief characteristic ...

In the corner there is the figure of Christ on the Cross, to which this method has given the most marvellous effect of light and shadow. Indeed, the whole picture is almost uncanny in its effectiveness and in the ...

... each case to the attraction of an invisible companion, the period of revolution of Sirius being about half a century. Later he said: "I adhere to the conviction that Procyon and Sirius form real binary systems, consisting of a visible and an invisible star. There is no reason to suppose luminosity an essential quality of cosmical bodies. The visibility of countless stars is no argument against the invisibility of countless others." This grand conception led Peters to compute more accurately the orbit, and to assign the place of the invisible companion ...

... The question might then have been asked—"Why do we not see it?"—we, especially, who occupy the mid region of the cluster—the very locality near which, at least, must be situated this inconceivable central sun. The astronomer, perhaps, at this point, took refuge in the suggestion of non-luminosity; and here analogy was suddenly let fall. But even admitting the central orb non-luminous, how did he manage to explain its failure to be rendered visible by the incalculable host of glorious suns glaring in all directions about it? No doubt what he finally maintained was merely a centre of gravity ...

The system of the two stars, which were about 31/4 millions of miles apart, considered as a whole, was approaching us with a velocity of 2.4 miles a second. The great difference in luminosity of the two stars, not less than fifty times, suggested rather that they were in different stages of condensation, and dissimilar in density. It was obvious that if the orbit of a star with an obscure ...

... various chemical and some very intense physiological reactions. Its salts are luminous in the dark, but this luminosity, at first very bright, gradually diminishes as the salts get older. We have here to do with a secondary reaction correlative to the production of the emanation, after which radium undergoes the transformations which will ...

... the whole stellar universe is made up of the same chemical materials as those with which we are familiar upon the earth. A part of the dazzling brilliance of the noonday sun is due to the vapor of iron floating in his atmosphere, and the faint luminosity of the remotest cloudlike nebula is the glow of just such hydrogen as enters into every drop of water ...

... existence by this fibre of reality which was part of his original structure. The epilogue—Sludge's outbreak against his corrupter and tormentor—stands as evidence of the fact that no purifying, no cleansing, no really illuminating power remains in what is now only a putrescent luminosity within him. His rage is natural and dramatically true; a noble rage would be to his honour. This is a base and poisonous passion with no virtue in it, and the passion, flaring for a moment, sinks idly into as base a fingering ...

... beautiful and winning. It seemed as if she and not the pink mountain blossoms must be responsible for all that haunting redolence in this landscape of passionless gray. Her brown eyes burned with glorious luminosity. Her color pulsed with health and the joyance of existence. Her red lips quivered with unuttered ecstacies that surged in the depths of her nature. Even the bright brown strands of her hair, escaping the prison of ...

... without the hardness that belongs to real precious stones; for indeed she shone like a jewel, thanks to the lustre of her eyes in artificial light. Whether from humidity or some quality of their substance, I do not know, but they reflected the rays as I have rarely seen eyes do; and in their luminosity her whole face seemed to have part, so that her presence had an effect of warm brilliancy that lured and dazzled you. To see her emerge from the darkness of the Faringfield coach, or from her sedan-chair, ...

... water-colorists, founded originally by Cozens (1752-1799) and Girtin (1775-1802), came into prominence and developed English art in a new direction. It began to show with a new force the transparency of skies, the luminosity of shadows, the delicacy and grace of clouds, the brilliancy of light and color. Cozens and Blake were primitives in the use of the medium, but Stothard (1755-1834) employed it with much sentiment, charm, and plein-air effect. Turner was quite a master of it, and his most permanent ...

... translated, their chief attraction lies, I think, in what they reveal to us of the human nature of their authors. Tanabata-tsum['e] still represents for us the Japanese wife, worshipfully loving;—Hikoboshi appears to us with none of the luminosity of the god, but as the young Japanese husband of the sixth or seventh century, before Chinese ethical convention had begun to exercise its restraint upon life and literature. Also these poems interest us by their expression of the early feeling for natural beauty. In them we find the ...

And now it was discovered that the labyrinth of passages and chambers extended far beyond the area covered by the superstructure, many of the chambers having evidently ...

... just the combination calculated to lead a spirited and brave people through such a trying crisis as the American Revolution. His star was not dark and bright by turns—did not reveal itself in uncertain and fitful glimmerings—but shone with a full and steady luminosity across the troubled night of a nation's beginning. Under these broad and beneficent rays the Ship of State was guided, through a sea of chaos, to safe anchorage. The voyage across those seven eventful years was one that tried men's souls. ...

... arrived at various absurd and erroneous conclusions. On directing his telescope to this luminous tract, Galileo discovered, to his inexpressible admiration, that it consists of a vast multitude of stars, too minute to be visible to the naked eye. He also discerned that its milky luminosity is created by the blended light of myriads of stars, so remote as to be incapable of definition by his telescope. In his 'Nuncius Sidereus' he gives an account of his observations of the Galaxy and expresses his satisfaction that he has been enabled to terminate ...

... Michigan was a brightly luminous green point that must be where we were, I decided. And for some reason the colored areas representing Los Alamos and Atlantic Highlands were glowing brighter than the others—they had an active luminosity. Los Alamos was blue, Atla-Hi violet. Los Alamos was shown having more territory than I expected. Savannah Fortress for that matter was a whole lot bigger than I'd have made it, pushing out pseudopods west and northeast along the coast, though its red didn't ...

... still contained in the mother's womb. If I happen by accident to crush a female big with germs that have reached maturity, a shiny streak runs along my fingers, as though I had broken some vessel filled with a phosphorescent fluid. The lens shows me that I am wrong. The luminosity comes from the cluster of eggs forced out of the ovary. Besides, as laying-time approaches, the phosphorescence of the eggs is already made manifest without this clumsy midwifery. A soft opalescent light shines through the skin of ...
