...fault of the school board, which had labored to make integration work. The board's dilemma was similar to that of a drayman, he explained, who was ordered to go from "Point A" to "Point B," and in doing so, to cross a bridge over a deep chasm. The bridge, however, had collapsed. Would it be right, asked he, to require the drayman to make the trip...
...deep underground explosion sends no air waves, but such explosions, and surface explosions too, send seismic waves through the earth. A station in a quiet place can detect the waves from a one-kiloton explosion as much as 2,200 miles away. The detecting apparatus is accurate enough to pinpoint the explosion within an area of 40-80 sq. mi., less than one-quarter the area of New York City...
Each of these methods, the East-West experts pointed out, has its faults. Acoustic waves from a volcanic eruption, for instance, can be mistaken for waves from a nuclear test. Seismic waves from earthquakes can be misinterpreted, too. Nuclear tests deep under the earth or ocean yield no radioactive fallout, send out no air waves or radio waves. But they do send waves through the ocean, the earth, or both. Each type of test is detectable by one or more methods...
Neither Russians nor Americans consider the system infallible. In 20 to 100 cases a year, natural earthquakes might be mistaken for deep underground tests. So they recommended that the international organization running the control system be permitted to go immediately to any suspected area and look for evidence of testing. Human ingenuity might find some way to fool this inspection too. but the experts decided that the risk of exposure would be extremely high...
...they completed in 1954, but the film showed a massive building in an unnamed Siberian town. Inside was a monster reactor yielding 100,000 kw. of electricity. Five more like it under construction will make the plant the world's biggest. General consensus was that the Russians, put deep in the shade by the U.S. technical exhibit, made the late announcement-by-inovie as a Sputnik-like surprise...
