Ray (anatomy)

“ As I watched, fixing my view now on the space directly in our path, I saw that our disintegrator ray men were at work. Deep in the bowels of the Ertak, the moan of the ray generators had deepened in note; I could even feel the slight vibration beneath my feet. [122]
One of the meteorites slowly crumbled on top, the dust of disintegration hovering in a compact mass about the body. More and more of it melted away. The spinning motion grew irregular, eccentric, as the center of gravity was changed by the action of the ray. ”

“ For the ray has really travelled from C to E, and from E to O, and it is that journey which determines the distance of the object; and hence we see ourselves as far beyond the mirror as we stand from it. Though a ray is here taken only from one part of the face, it may be easily 85 conceived that rays from every other part of the face must produce a similar effect. ”

“ Trembling, Mea-Quin turned to Dos-Tev. “It had done its duty as you foresaw. The momentum was distributed, our ship received its alloted portion, the Moon absorbed the greater part. My son, you have done much for the defeat of Ay-Artz. Now I shall give you one more thing I have labored on. What ray has been sought for long and declared impossible? It is a ray that matter will not stop, a ray which no mechanism of matter can screen against and which will bring tearing, burning death to any living being.” ”

“ PART III Spacehounds of IPC The question of rays—their expanding power for good and evil—is receiving increasing attention from scientists. The x-ray has been found to be very beneficial, given in certain quantities, but extremely inimical to health, and even fatal, if too much exposure is given. The powers of the cosmic rays have not been fully discovered as yet. ”

“ These characteristics are greatly modified when cross-rays intervene from evil planets, and then one is unreliable, a busybody, has a sharp unkind word or a sneer for every one.”
23“Oh, my! I hope no bad ray crossed my Mercurian ray at birth,” said Ione.
“You need not fear,” answered one of the island people; “you were born under a ray from Venus.”
“Goodness! How do you know that?” asked Ione.
“By your face. We planet people can tell the moment we see a person what planet or planets influenced at birth.” ”

“ No doubt the ray passing over many things in such condition, enlightens the things after them, and there is no visible thing which it does not reach, with the surpassing greatness of its own splendour. Further also, it contributes to the generation of sensible bodies, and moves them to life, and nourishes, and increases, and perfects, and purifies and renews; and the light is both measure and number of hours, days, and all our time. ”

“ And the ray feed released it without control; it released all the energy it could suck in from space about it, as one single beam of cosmic energy, somewhat lower than the regular cosmics, and it flashed out in a beam as solid matter.
There was air about the ship, and the air instantly exploded into atoms of a different sort, threw off their electrons, and were raised to the temperature at which no atom can exist, and became protons and electrons. But so rapidly was that coil sucking energy from space that space tended to close in about it, and in enormous spurts the energy flooded out. ”

“ Imagine what would happen if we directed this against the side of a mountain—the entire mass of rock would at once fly off at unimaginable speed, crashing ahead with terrific power, as all the molecules suddenly moved in the same direction. Nothing in all the Universe could hold together against it! It's a disintegration ray of a sort—a ray that will tear, or crush, for we can either make one half move away from the other—or we can reverse the power, and make one half drive toward the other with all the terrific power of its molecules! ”

“ Then, again, if we look at faint stars, they do not grow any brighter as we look. Each ray sends its message to the brain, and that is all; we cannot heap them up in our eye, and, indeed, after a time we see less, because our nerves grow tired. But on a photographic plate in a telescope, each ray in its turn does a little work upon the chemicals, and the longer the plate remains, the stronger the picture becomes. ”

“ It has here, practically the same fault which the artificial matter had on your world.
"As I see it, the ray is actually a directed gravitational field.
"Now here is one thing that makes it more interesting, and more useful. It seems to defy the laws of mechanics. It acts, but there is no apparent reaction! A small ship can swing a world! Remember, the field that generates the attraction is an integral, interwoven part of the mesh of Space. It is created by something outside of itself. Like the artificial matter, it exists there, and there alone. ”

“ Frequently it consists of single rays, which, standing close together, point in an almost parallel direction towards the magnetic pole. These become more intensely bright with each successive wave of light; hence each ray appears to flash and dart continually, and their green and red edges dance up and down as the waves of light run through them. Often, again, the rays extend through the whole length of the band, and reach almost up to the magnetic pole. These are sharply marked, but lighter in colour than the band itself, and in this particular form they are at some distance from each other. ”

“ Ray Cummings has delighted two generations of science fantasy readers with his unforgettable tales of the infinitely small and the infinitely large. We are all atom conscious today, but Ray was the first to discern the realms of gold spinning in miraculous splendor far below the threshold of the visible. ”

“ You know, Ralton, that the cosmic ray vibrations are the shortest in wave-length of all the etheric vibrations, ranking just below the radio-active waves. First comprehensively studied but a few years ago by Dr. Millikan, the cosmic rays have been found to permeate all space, shot forth from the white-hot furnaces of stars just as heat-vibrations and light-vibrations are shot forth. And it was the cosmic ray vibrations, we found, that had in past ages built up the organic compounds of living protoplasm from inorganic elements of sea-silt. ”

“ As to the eye itself, certain of the wave lengths are competent to produce the sensation we call light, but the same ray will heat the face of a thermopile or produce photographic effects if permitted to act upon the proper material, so there is no more propriety in calling it a light ray than in calling it a heat ray or an actinic ray. What the ray will do depends solely upon what kind of matter it falls upon, and all three of these names, light, heat, and actinism, are names of effects of radiant energy. ”

“ There is nothing more required to determine whether the Rays of Light [Pg 360] which fall upon the second Crystal shall be refracted after the usual or after the unusual manner, but to turn about this Crystal, so that the Coast of this Crystal's unusual Refraction may be on this or on that side of the Ray. And therefore every Ray may be consider'd as having four Sides or Quarters, two of which opposite to one another incline the Ray to be refracted after the unusual manner, as often as either of them are turn'd towards the Coast of unusual Refraction ”

“ It is well known, that when a ray of light passing through the air falls obliquely upon the surface of any transparent body, suppose water or glass, and enters it, the ray will not pass on in that body in the same line it described through the air, but be turned off from the surface, so as to be less inclined to it after passing it, than before. ”

“ As heat from a fire warms all objects within the sphere of its radiations, so also the Aquarian ray will raise the earth's vibrations to a pitch we are as yet unable to comprehend, though we have demonstrations of the material workings of this force in the inventions which have revolutionized life within the memory of the present generation. We have wondered at the X-ray, which sees through the human body, but each one has a sense latent which when evolved will enable him to see through any number of bodies or to any distance. ”

“ In all these substances, however, if the plane of polarization of any ray is twisted within the medium like a right-handed screw, it will still be twisted like a right-handed screw if the ray is transmitted through the medium in the opposite direction. The direction in which the observer has to turn his analyser in order to extinguish the ray after introducing the medium into its path, is the same with reference to the observer whether the ray comes to him from the north or from the south. The direction of the rotation in space is of course reversed when the direction of the ray is reversed. ”

“ Of course, at the tip of every ray; exactly where they were when the rays were drawn up to form the summit of a sphere, so that the eyes, which are now at their extremities, were clustered together at their point of meeting. Where shall we look for the ovarian plates? At each angle of the five rays, because, when the broad zones of which they formed the summit were divided, they followed the split, and now occupy the place which, though it seems so different on the surface of the Star-Fish, is nevertheless, relatively to the rest of the body, the same as they occupied in the Sea-Urchin. ”

“ It is much better explained by supposing their eyes to be constructed to respond to wave-lengths either greater or less than those of mankind.
A ray of light, then, consists of a single line of undulations of a definite wave length, such that if it falls upon the eye it will produce sight; if it falls upon a thermo-pile it heats it by just the same quantity that another wave-length would heat it; if it falls upon matter in unstable chemical relations, it will do chemical work, depending upon the kinds of matter. A red ray is as effective for some substances as a violet ray is for others. ”

“ If the rays had any existence outside of the eye, they would still be seen; instead of which, the whole of them disappear when the luminous point, or, in the case of the street-lamp, when the flame, is covered by the screen. A second proof that the origin of the phenomenon is in the eye, and not in the object, is afforded by the fact that if, while attentively observing the rays, we incline the head, the rays turn with the eyes, so that when the head is resting on the shoulder the ray which appeared vertical becomes horizontal. ”

“ And if the ray were completely pure and free from all these atoms and particles, even from the minutest specks of dust, it would appear completely dark and invisible to the eye, since everything that could be seen would be absent from it — namely, the objects of sight. For the eye would find no objects whereon to rest, since light is no proper object of vision, but the means whereby that which is visible is seen ”

“ It is enough for humanity to have arrived at this for the present—for we have not yet sounded the heights or depths of even the first Seven radiations which we all agree to recognise. We admit seven tones of music, and seven tones of colour, but what of our seven rays of light? We have the ‘violet ray,’ the ‘X ray’—and a newly discovered ray showing the working bodily organism of man,—but there are Seven Rays piercing the density of ether, which are intended for the use and benefit of the human being, and which are closely connected with his personality, his needs and his life. ”

“ In moving about to get different points of view, he suddenly found that he had come between it and the ray, and that the crystal none the less remained luminous. Greatly astonished, he lifted it out of the light ray and carried it to the darkest part of the shop. ”

“ We may, however, sketch out a brief chapter in modern sidereal astronomy, which seems to throw a ray of light into the constituents of the vast abyss of space which lies beyond the range of our telescopes. The ray of light is no doubt but a feeble one, but we must take whatever information we can obtain, even though it may fall far short of that which an intellectual curiosity will desire. ”

“ The "ray" in geometric optics is an abstraction, or "instrument", that can be used to predict the path of light. - "can be used" or "is used"? is used. ScienceApologist (talk) 20:23, 20 April 2009 (UTC) A light ray is a ray that is perpendicular to the light's wavefronts (and therefore collinear with the wave vector) . - 1) A ray is a ray? Usually we try not to repeat the word itself in the definition, as the definition is supposed to clarify to the uninitiated. 2) I am unsure what "collinear with the wave vector" means. A "light ray" is a "geometrical ray". ”

“ It projects an invisible ray, the vibrations of which effect such a change in the constitution of metals as to cause them to disintegrate. I am not a scientist; I do not fully understand the exact explanation of the phenomenon, but from what I was able to gather while the new weapon was being discussed in Jahar I am under the impression that these rays change the polarity of the protons in metallic substances, releasing the whole mass as free electrons. ”

“ But if a ray that has been traveling through warm and light air, suddenly plunges into air cold and heavy, it is put out of the way by such a circumstance, and in the moment of making such a change, it alters its direction. Still more, a ray of light that has been traveling in a straight line through air, is put out of its course on entering the denser medium of water ”
