The First Men in the Moon Then life will roll out through our glad hearts and willing hands as the sun's light pours abroad—only that we are conscious, we feel this light, this heat, this radiant energy. The Forerunner, Volume 1 (1909-1910) It has, indeed, been suggested that the newest form of radiant energy, the famous X-ray of Professor Roentgen's discovery, is a longitudinal vibration, but this is a mere surmise. A History of Science — Volume 3 The temperature of the room was normal, so that the treatment was essentially by radiant energy and not by heat.

Artificial Light Its Influence upon Civilization All these things, he said, radiate out from centres, and act on bodies at a distance, whence comes the term "radiant energy." The First Men in the Moon Besides these, vacuum-tube discharges and sparks have been utilized as sources for radiant energy and "electrical" treatment. Artificial Light Its Influence upon Civilization The proof that all known forms of radiant energy move through space at the same rate of speed is regarded as practically a demonstration that but one plenum—one ether—is concerned in their transmission. A History of Science — Volume 3 These are usually rich in ultra-violet rays and therefore have their best applications in processes demanding this kind of radiant energy. Artificial Light Its Influence upon Civilization These light-sources appear to emit only visible energy and, therefore, are efficient as radiators of luminous radiant energy. Artificial Light Its Influence upon Civilization Now almost all substances are opaque to some form or other of radiant energy. The First Men in the Moon All modern illuminants emit radiant energy, which does not affect the ordinary photographic plate. Artificial Light Its Influence upon Civilization "Light Energy," by Cleaves, is a large volume devoted to light-therapy, germicidal action of radiant energy, etc. Artificial Light Its Influence upon Civilization All this time its luminous efficiency is increasing, because it is radiating not only an increasing percentage of visible radiant energy but an increasing amount of the most effective luminous energy. Artificial Light Its Influence upon Civilization That radiant energy which is wholly of a wave-length of maximum visibility, or, in other words, excites the sensation of yellow-green, is the most efficient in producing luminous sensation. Artificial Light Its Influence upon Civilization When light is emitted by virtue of its temperature much invisible radiant energy accompanies the visible energy. Artificial Light Its Influence upon Civilization The eye is able to convert radiant energy of different wave-lengths into certain fixed proportions of light. Artificial Light Its Influence upon Civilization There are many instances of light being emitted without being accompanied by appreciable amounts of invisible radiant energy and it is natural to hope for practical possibilities in this direction. Artificial Light Its Influence upon Civilization It is an efficient radiator of light, for its light is "cold"; that is, it does not appear to be accompanied by invisible radiant energy. Artificial Light Its Influence upon Civilization The dye fluoresces red under the illumination of ultra-violet, violet, and blue rays; that is, it has the property of converting radiation of these wave-lengths into radiant energy of longer wave-lengths. Artificial Light Its Influence upon Civilization Ultra-violet, violet, and blue rays are generally the most effective radiant energy for excitation purposes. Artificial Light Its Influence upon Civilization Great progress in the future of light-production as indicated by present knowledge appears to lie in the production of light which is unaccompanied by invisible radiant energy.

Artificial Light Its Influence upon Civilization However, there still appears to be a difference of opinion as to the destructive effect of radiant energy upon bacteria in living tissue. Artificial Light Its Influence upon Civilization Another advantage of the flame-arc in photochemistry is the ease with which the quality or spectral character of the radiant energy may be altered by varying the chemical salts used in the carbons. Artificial Light Its Influence upon Civilization From the great amount of data available it appears reasonable to conclude that radiant energy is a powerful bactericidal agency but that the action is due chiefly to ultra-violet rays. Artificial Light Its Influence upon Civilization The foregoing remarks about the bactericidal action of radiant energy apply only to bacteria in water, in cultures, and on the surface of the body. Artificial Light Its Influence upon Civilization There is much uncertainty as to the ability of radiant energy to destroy bacteria within living tissue. Artificial Light Its Influence upon Civilization Finsen, a pioneer in the use of radiant energy in the treatment of disease, effected many wonderful cures and believed that the bacteria were directly destroyed by the ultra-violet rays. Artificial Light Its Influence upon Civilization For example, strontium fluoride is used in the red flame-arc whose radiant energy is rich in red and yellow. Artificial Light Its Influence upon Civilization Thus he was able to concentrate upon the diseased skin radiant energy consisting of visible and near ultra-violet rays. Artificial Light Its Influence upon Civilization Certainly if radiant energy is effective, it has a great advantage over drugs. Artificial Light Its Influence upon Civilization The water supplied to the sterilizer should be clear and free of suspended matter, in order that the radiant energy may be effective. Artificial Light Its Influence upon Civilization These glimpses of the use of the radiant energy as a means of regaining and retaining good health suggest greater possibilities when the facts become thoroughly established and correlated. Artificial Light Its Influence upon Civilization The radiant energy emitted by the snow-white flame-arc is a close approximation to average daylight both as to visible and to ultra-violet rays. Artificial Light Its Influence upon Civilization It cannot supply just the desired radiant energy for one purpose and at the same time serve for another purpose in the best manner. Artificial Light Its Influence upon Civilization These absences are beneficial to some processes, but man in the highly organized activity of present civilization desires radiant energy of various qualities available at any time. Artificial Light Its Influence upon Civilization Certain kinds of radiant energy are required for photography and other photochemical processes and a vast array of colored light is demanded for displays and for effects upon the stage. Artificial Light Its Influence upon Civilization The former may be said to be white light and its spectrum indicates the presence of visible radiant energy of all wave-lengths in approximately equal proportions. Artificial Light Its Influence upon Civilization Very mysterious effects are sometimes attributed to radiant energy, which occasionally border upon superstition.
