...other gadget: sonar, radar's supersonic cousin. A sonar-equipped locomotive, by means of an oscillator and amplifier, would keep sending out whistle blasts pitched so high that nobody could hear them; but if a signal box ahead had its danger arm up, a reflector would send back the sound waves to the locomotive. There a microphone would detect the supersonic racket, a bell would ring (or a light flash), and the engineer would throttle down to his foggy-foggy...
...female veterans--whose average age, experience, and interests make them veteran females as well--represent all of the services, some of the overseas theaters, and both the castes. They were nurses, photographic technicians, radar experts, Link trainer instructors, and at least one spent her time chatting with the boys at a local PX. Cynthia Brott, Radcliffe '48, spent two years overseas in Iceland and England wielding needled and syringe with the Army Nurse Corps. Anne Kennedy, one of the Wellesley's more nature women, ground out the war at Wright Field, Ohio, as a photographic technician in an optical research...
...Churchill, Manitoba (tentatively, Canada would have 500 men there, the U.S. 100), at forlorn little landing strips like "Crystal 1," at Fort Chimo in northeastern Quebec, and "Crystal 2," on Baffin Island's Frobisher Bay. Soldiers of both nations would also staff a ring of weather stations and radar listening posts all across the continent's bleak Arctic vastness and down the east and west coasts to the U.S. The suggestions sounded simple. But the arguments pro & con were complex...
Most cooking methods-baking, boiling, frying-date from stone-ax days. They all heat food from the outside in. The Raytheon Co., prolific spawner of radar tubes, has shown short-order cooks something new; a "range" which cooks food from the inside...
...Pierce of Harvard bounced radio waves off the meteor trails. His gadget gave a dramatic whistle, like the screech of an approaching shell, whenever a meteor hit the atmosphere. Other scientists took to radar, which can see through clouds as if they were Cellophane. At the Bureau of Standards' laboratory near Sterling, Va., they watched bright blobs of light on a radarscope. These were made, they said, by the radar beam reflected from hot, ionized gases-the remains of meteors as they disintegrated in the atmosphere 50 to 80 miles...
