...experiment with a borrowed electromagnet and a quarter's worth of paraffin that led to his Nobel-prizewinning "nuclear resonance" system for measuring atomic properties. In his early studies of the 21-cm. radio waves coming from hydrogen clouds in interstellar space, Purcell made do with a hastily devised antenna hung outside his Harvard laboratory. It looked like a horn left over from an ancient phonograph, but it worked...
...within its walls, with enough switching equipment to sustain a city of 20,000. The Oakland controllers are in fingertip communication with 40 airport control towers and radar approach control centers in California and Nevada. Ten transmitters perched on peaks provide ground-to-air relays. A long-range microwave antenna speeds the blips of moving light to the center's radar screens, enabling the safety officers to "see" the planes they are directing...
...later, a familiar voice filled the room : "This is President Eisenhower speaking." The President's words, spoken into a White House tape recorder months before, had just been broadcast from Goldstone, Calif., and had carried clearly across 2,500 miles of space to Holmdel's horn-shaped antenna. It was a major space-age breakthrough. After one earlier failure, the U.S. National Aeronautics and Space Administration had successfully launched an Echo satellite, a huge, metal ized balloon capable of reflecting radio messages from earth. The U.S. thus opened the door to a new system of inter continental communications...
...Valhalla from heavy, cardboard-shield and plaster-throne cliches. But by now, this once revolutionary style has produced some bothersome clichés of its own. The basic stage set of last week's Ring was an eight-ton, segmented concave disk looking somewhat like a huge radar antenna. In the second and fourth Rheingold scenes it was used intact, tilted toward the audience to suggest the rugged slopes of Wotan's mountain home; in other scenes the disk's movable segments represented a cave...
...long-range detection of attacking aircraft, the huge (403 ft.) ZPG-3W U.S. Navy blimp made an ideal rescue ship. Its slow cruising speed (30-60 knots) and low operating altitude (under 500 ft.) provided an almost perfect platform for the giant (40 ft., 12,000 lbs.) radar antenna rotating inside the helium-filled gas bag. Its great endurance (up to 95 hours without refueling) promised ample range as it beat to seaward off the New Jersey shore one day last week in search of a racing sloop, overdue on a Bermuda-to-Long Island...
