When the rocket re-enters the atmosphere it could travel about 1000 miles before landing, leaving a blazing trail if it falls at night. If it re-enters in the daytime, it could leave a dark trail in the sky as it gives off particles and vapor...
...controlled fusion is to heat the material, usually deuterium, so hot that its nuclei will combine. This temperature is something like 100 million degrees C., and it must be held for an appreciable fraction of a second while the reaction takes place. Since all known materials turn into vapor at a few thousand degrees, the hot deuterium cannot be contained in any ordinary pressure vessel...
...overthrow of the Manchu dynasty and the founding of the Chinese Republic by Dr. Sun Yatsen. Last week, on a bright, breezy day, Generalissimo Chiang Kai-shek watched his U.S.-equipped Nationalist army roll by in an impressive display of motorized armor. Overhead Chinese and U.S. jets left vapor trails above the fleecy clouds...
...Simons' instruments picked up traces of moisture at 70,000 ft., the first time it had been noted above 50,000 ft. This means that the next generation of fighters and bombers will be followed by the same path-tracing vapor trails that dogged aircraft in World...
...gets around this problem by putting frozen foods in a vacuum chamber and shooting through them a powerful blast of ultrahigh-frequency radio energy. The waves agitate the molecules in the interior of the food and generate just enough heat to make the ice crystals turn directly into water vapor. If the job is handled properly, the food loses up to nine-tenths of its weight and turns into a brittle sort of substance while staying far below the freezing point. Chemical changes, which would damage flavor, cannot take place. Even unstable vitamins are preserved...
