MICROWAVE OVEN In 1946 Percy Spencer, a Raytheon Corp. self-taught engineer studying radars, tested a vacuum tube called a magnetron, and something unusual happened: a candy bar in his pocket melted. The intrigued scientist placed popcorn kernels near the tube and then an egg, watching in amazement as the kernels popped and the yolk splattered. Spencer realized that exposure to low-density microwave energy could cook food quickly, and he created the first commercial microwave a year later. Smaller models followed, revolutionizing a certain kind of cooking...
...topflight British scientist who chairmaned the Air Ministry's secret research committee that devised air weapons for World War II, supervised and contributed significantly to the development of radar in time to provide a chain of radar stations for the Battle of Britain, personally carried (1940) the magnetron, heart of radar, to the U.S. where it was quickly put into mass production; in Fareham, England...
...Barlow believes that plain copper pipe can replace multiwire telephone cables as well as coaxial television cables (copper tubes with insulated copper cores). It is much cheaper than either of them. Chief remaining obstacle is the high cost of the magnetron tubes that must be used in its repeater stations, but he thinks their price can be cut down by large-scale manufacture...
...point to plenty of evidence that they are right. From Connecticut to Maine, hundreds of small new factories are now turning out products that were mere dreams a few years ago. Around Boston, a cluster of companies spew forth such electronic gadgets as diodes and transistors, computers and magnetron tubes. In Cambridge, Mass., along "Research Row" on the Charles River, scientists from M.I.T., Harvard and numerous companies bend over their gurgling test tubes, devising new products and methods for plastics, electronics and other industries. In Cohasset, Mass., a small seashore town, D. S. Kennedy Co. turns out giant radar antennas...
...flying-saucer expert by association with talented Oilman Silas M. Newton of Denver, who, he says, locates oil deposits by their microwaves (microwaves do not penetrate rock). Through Newton, Scully met a mysterious "Dr. Gee," who does similar feats by detecting "magnetic waves" (which do not exist) with a magnetron (a radio transmitter tube, not a detection device). Flying saucers, says Dr. Gee (quoted by Scully), travel among the planets by magnetism. Their 3½-ft. crewmen have perfect teeth with no cavities. For food they carry little wafers. One wafer was dunked in a gallon of water. "It swelled...
