What is TIME? A hash of special interests, or a reflector of universal news ? If news appears in any department, print it (as indeed you do). Let unnewsworthy space-fillers alone. Your judgment may err, and you may profit from occasional advice, but we trust your good sense of balance to be better than any of us could achieve. Your editorial discrimination, as well as your condensation, is worthy of our praise and loyalty. Avoid "departments...
...miles apart. They are searchlights and all night they sweep the sky in steady circles, their narrow shafts swinging around heaven from anchorages on hilltops. For miles ahead you watch one, catching its brief flash as the beam swings high over your road. Drawing nearer, you see a reflector revolving on a small tower of skeletal steel, a land lighthouse functioning impersonally in solitude. You pass, and see a fainter arm of light waving over the hills ahead, the next eye. They are the night beacons for the U. S. airmail...
...difficult to detect and measure as a whisper in a hurricane. Star heat is best studied at altitudes where Earth's atmosphere is rare. To rare-aired Mount Wilson, therefore, went Dr. Abbot, where he can introduce starlight reflected from the 100-inch Carnegie Institute sky-reflector into his newest and finest radiometer-an instrument so delicate that a part of it is constructed of flies' wings; an instrument ten times as sensitive as Dr. Abbot's last radiometer, with which, "if the Earth were flat and the atmosphere perfectly transparent, it would have been possible...
...station of the College Observatory within the next two years, it was announced today by Dr. Harlow Shapley, director of the observatory. The contract for this giant research instrument has just been awarded to a firm in Pittsburgh, Pa., that has made many large telescopes, including the 72-inch reflector at the Dominion Observatory, Victoria, B. C., the world's second largest...
...Harvard telescope will be a reflector also, in which a concave mirror sixty inches in diameter replaces the convex lens of the more familiar, or refracting type. The mirror faces the star and, as it is concave, or dish-shaped, the light rays converge after being reflected from it. They are reflected to the side of the instrument by a second, flat mirror, in one type, and are brought to a focus on a photograph plate, or in an eyepiece, if the telescope is being used visually...
