Their task was not easy. Radio astronomy depends on electromagnetic waves, which are much harder to handle than the visible light that the human eye receives with such marvelous ease and precision. Radio waves are many thousand times longer than light waves, and because of inflexible laws of physics, this...
Many of the newly arrived 4,000 Red troops are electronics and radar technicians sent to install and man Castro's first missiles. The SA-2 rockets require extensive guidance radar. Other Russians will operate 250-mile-range surveillance radar and electromagnetic tracking posts to monitor Cape Canaveral shots...
Until recently, said Dr. Chiu, stars were thought to lose energy (and therefore mass, which turns into energy) in the form of light, heat and other kinds of electromagnetic radiation. Now many scientists see a different picture. The hot centers of stars are believed to generate neutrinos. Since neutrinos have...
CONELRAD is an abbreviation for Control of Electromagnetic Radiation. It is an emergency communications system in which all commercial broadcast stations will leave the air except those assigned to instruct the public at 640 and 1,240 kilocycles. It is intended to nullify enemy equipment that uses radio signals to...
Low & High Tests. If the Russians were trying to hide their tests, they would have held them underground. Underground explosions send no ordinary radio signals or barometric waves. They are invisible to radar, and they scatter no telltale fallout. But they do create powerful earth waves that travel in the...
