...abysmal reaches of space, Dr. Einstein advanced in 1915 his General Theory of Relativity, which brought celestial performances into the four-dimensional theatre of space-time and made gravity an effect of space-time's curvature. Today Relativity is as familiar a guide to astronomers as a radio beam to an aviator...
...wire transmission of news pictures, which may be Publisher Hearst's answer to the Associated Press's Wirephoto (TIME, April 29). The Hearst invention is portable, requires no leased wires, can be hooked up to any telephone. It resembles a conventional telephoto set in employing a tiny beam of light and photo-electric cell to scan the photograph. But the light impulses are converted into a shrill whistling sound. An ordinary telephone transmitter is clamped in place to catch the sound. At the receiving end of the telephone wire the waves are caught, re-converted into light which...
Inside the huge cabin the six stalwart young men in blue uniforms and white caps were too busy to do anything but their jobs. With the ship guided by a robot pilot and directional radio beam, Captain Edwin C. Musick and Chief Pilot Sullivan checked the course with blind-flying instruments. Engineering Officer Wright had 71 other instruments to read. Weather reports were received every 20 minutes, position reports transmitted every half-hour.

...positive print is placed on a cylinder which revolves 100 times per minute and moves horizontally one inch per minute. A tiny beam of light, trained on the picture at a 45 degree angle, is reflected to a "light valve." Inside the valve is a shutter which vibrates 2,400 times per second-faster than a humming bird's wings. The reflected beam sends the lights & shadows of the picture through the shutter to a conventional photo-electric cell ("electric eye")- There the image is translated into electric impulses which flash over the wires-10.000 mi., if desired...
