Last fortnight Dr. Donald H. Andrews of Johns Hopkins University described a bolometer to top them all. Its sensitive surface is columbium nitride cooled by liquid hydrogen to minus 432° F. At this temperature-close to absolute zero-columbium nitride becomes "superconductive"; its electrical resistance almost vanishes. When a heat ray hits it and warms it only one millionth of a degree, it gives a clear electrical signal...
Shooting any sort of projectile beyond the earth's gravitational field would take enormous energy. Prewar energy sources could barely do it, even in theory. One calculation: a 100-ton spaceship would need nearly 8,000 tons of gasoline and liquid oxygen to toss it into space...
...teeth protruding. But the Olney neighborhood liked her. By the time she was 17 she was singing in a Camden, N.J. nightclub, where she earned, as combination hatcheck-girl, vocalist and electrician, about $85 a week. The turning-point in her career came when she met a handsome, liquid-eyed insurance broker named Frank Kinsella...
...factory and tried every short cut he could think of. First step was pouring a solution of uranium salt and other chemicals into a battery of wooden washtubs on the roof. There the photochemical action of the ultraviolet rays in sunlight (on cloudy days, sun lamps) converted the transparent liquid into green, powdery potassium uranium fluoride. The second step: melting this secondary uranium salt in graphite cups for electrolytic separation of the pure metal. The electrodes were raised and lowered by automobile jacks. The final step was simple melting and casting...
...diving suits equipped with two oxygen tanks, submarine-type air cleansing devices, tubes for liquid food, the fukuryus could operate in deep water (most effectively at 50 feet), walk under water more than a mile an hour, stay under about ten hours. Each carried at the end of a stick a ten-kilogram explosive charge with contact fuse. A floating chamber behind the charge made it easy to handle. The fukuryus, organized in squads and platoons, were to wait till a vessel passed overhead, then ram the mine into the ship's bottom. They were to be protected from...
