Theirs is a job without recompense, with- out glory, without even the thrill of danger— yet they have kept to their w? posts. But there are times, when the fog rolls in or the skies are dark, that % - even the keenest human eyes are not enough. Then, along our shores and ¥ \ . about our cities, we can depend on electronic sentries to scan the skies. s . -1 1 b § ~® e iecrica s gfflfl are .51'00 (7 ,, What is Electronics, Anyway? s BLIND «s « BAT 1. What is an electron? The electron is one of the fundamental particles of matter and electricity. Electrons are part of atoms; atoms make up molecules. And molecules, in turn, make up all the matter in the world, and in the uni- verse of which the world is but a small part. The elec- tron is far too small to be seen, even with the best microscopes. Thirty thousand trillion trillion electrons RADAR is America’s best plane spotter. Like the bat, which is equipped by nature with one of the most remarkable sets of blind-flying “instruments” known to man, radar can operate “blind” in night and fog.
