Energy that is radiated or transmitted in the form of rays or waves or particles.
2.
The act of spreading outward from a central source.
3.

"Radiation" Quotes from Famous Books



... flying fragments then they were spent and over. But Carolinum, which belonged to the beta group of Hyslop's so-called 'suspended degenerator' elements, once its degenerative process had been induced, continued a furious radiation of energy and nothing could arrest it. Of all Hyslop's artificial elements, Carolinum was the most heavily stored with energy and the most dangerous to make and handle. To this day it remains the most potent degenerator known. What the earlier twentieth-century ...

... pictures. Owen praised the architecture. It was, he said, the most perfectly-constructed little gallery he had ever seen, and he ought to know, for he had seen every gallery in Europe. But he had not been here for many years and had quite forgotten it. "A veritable radiation of masterpieces," he said, stepping aside to see one. But the girl was the greater attraction, and only half satisfied he returned to her, and when the attraction of the pictures grew irresistible he tried to engage her ...

... force of him, radiated like a tower code-beam. No one could be in his presence an instant without feeling it. A power that enwrapped you; made you feel like a child. Helpless. Anxious to placate a possible wrath that would be devastating; anxious—absurdly—for a smile. It was a radiation of genius, humbling ...

... while ago, was now familiar, but to much I was still a stranger, and presently I was wondering concerning the occupants of the houses I was passing. The shabby gentility and dull respectability of the latter was depressing, and to escape the radiation of their dreariness I turned into first one street and then another, and as I walked the girl with the boyish face walked with me, the face with its hunted fear. She had held the baby as if frightened, and when she turned the corner ...

... scene, that was broken only by the click of hoofs of horse and burro upon the rocks, and the clatter of the loose stones they dislodged that rolled and skipped down the side. Not a breath of air was stirring, and the sun blazed down from the zenith with such fierce and direct radiation that the wayfarer needed not to observe the shadows to note its exact position in the heavens. Singly among the broken blocks, and in banks along the ledges, the cactus had burst under the heat, as it were, into the ...

... five times greater than the necessary oxygen; and we are therefore obliged to create a draught which carries away to the chimney a considerable portion of the heat developed. The combustion, moreover, is never perfect; and some heat is lost by conduction and radiation. The principal loss is by hot gases escaping from the flues to the chimney. Even with well-set boilers, the temperature in the chimney varies from 400 deg. to 600 deg. Fahr. Taking the mean of 500 deg., this would represent a large proportion ...

... painful and there is danger of going off into the sleep that knows no waking. On New Year's day morning the ground was frozen solid. All huddled about the fires, but the gale was so fierce that on the windward side there seemed to be no radiation of heat, so completely was the fire blown away from that side of the logs. On the leeward side the smoke suffocated and the sparks burned one, and men passed from one side to the other doubting which was the ...

A northern aspect has also the advantage of preserving a much more uniform temperature than a southern aspect, because the excessive radiation and evaporation in the southern slopes greatly reduces the temperature at night, while in the day they are heated to excess by the action of the sun's rays striking the surface nearly at right angles. ...

He, before any other investigator, showed that radiant heat is refracted according to the laws governing the refraction of light by transparent media; that a portion of the radiation from the sun is incapable of exciting the sensation of vision, and that this portion is the less refrangible; that the different colors of the spectrum possess very unequal heating powers, which are not proportional to their luminosity; that substances differ very ...

Prof. Young, of Princeton, in his Astronomy, p. 156, says, "The solar radiation can be accounted for on the hypothesis first proposed by Helmholtz, that the sun is shrinking slowly but continually. It is a matter of demonstration that an annual shrinkage of about 300 feet in the sun's diameter would liberate sufficient heat to keep up its radiation without any fall in its temperature".... ...

Material surfaces, it would appear, reflect them all in equal value, and the color of the resultant picture depends on the color of the foco frequencies. By altering these, a reddish, yellowish or bluish picture may be seen. In actual practice an orthochromatic mixture of frequencies ...

The alternate heat of the day and cold of the night—a cold which is often great, owing to the radiation into a cloudless sky—split the masses by alternate expansion and contraction, make great flakes peel off them like the coats of an onion, and give them these singularly picturesque shapes. All this part of the country is as eminently fit ...

And some go apart, out of the glare of life, into corners of obscurity, where the radiation of the lantern may still be faintly traced. But, indeed, with the new light there has come the time for new methods; the time of lanterns, the time of deductions from arbitrary first principles is over. The act of faith is no longer to follow your lantern, ...

... persons develop a delicateness and acuteness of smell which other persons do not even imagine. Now we have no real knowledge of how odors arise. That they are not the results of the radiation of very tiny parts is shown by the fact that certain bodies smell though they are known not to give off particles. Zinc, for example, and such things as copper, sulphur, and iron, have individual odors; the latter, particularly when it is kept polished by a great deal of friction,—e.g., in the ...

And the whole solar system may and probably did come into its present condition in this way. It certainly could have been so formed, and there is no reason for supposing that it was formed in any ...

This is true not only in the case of deep thought or vivid feeling, but also in the case of general mental "feelings," and emotional states. During such manifestations there is a radiation of mental or emotional vibrations from the brain or nervous centres of the system, which flows out in all directions just as do light and wireless electricity. The principal seats or centres of these radiations are (1) the several brains of man, viz., the cerebrum, ...
