...idea presents enormous difficulties. Seismologists would have to know exactly where and when to explode the bombs-an art that still eludes them, although they may eventually be able to predict quakes by carefully calculating earth stresses. Still more delicate would be the decision on the size of the bomb. The Miami seismologists-Cesare Emiliani, Christopher G. A. Harrison and Mary Swanson-say that the job probably could be done by high-yield nuclear devices of one to ten megatons, presumably H-bombs. But other seismologists point out that an explosion meant only to keep the earth's crust...
...Washington columnist, has specialized in books that "reveal the truth" about Government agencies. His purpose this time is to demonstrate the pervasive and gigantic nature of the U.S. espionage establishment. Tully credits U.S. espionage experts with remarkable success. To hear him tell it, hardly a sparrow falls to earth in the world without a U.S. spy taking note. The book is filled with what might be called incidental intelligence. In Jordan, a U.S. agent was told a week in advance of the date of the planned 1967 Israeli offensive. (The U.S. believed the information, but Nasser, who heard it independently...
After two months in orbit 300 miles above the earth, an automatic telescope designed and assembled at the Harvard College Observatory is working perfectly. The ultra-violet light experiment aboard Orbiting Solar Observatory VI (OSO-VI) "is meeting 100 per cent of our expectations," said William H. Parkinson, lecturer on Astronomy and co-director of the project. "We've got a winner...
...pound satellite was launched from Cape Kennedy on August 9. Besides the Harvard telescope, it contains 6 other experiments designed to measure solar emissions such as x-rays, ultraviolet light and neutrons that are ordinarily blocked from view by the upper layers of the earth's atmosphere. When ever the satellite emerges from the earth's shadow, two of these devices, including Harvard's telescope, constantly scan different portions of the sun's disc and record the intensity of the sun's radiation in varying sections of the spectrum...
Ultra-violet measurements, like these, are important because ultra-violet rays from the sun occasionally interfere with earth's radio communications, and the energy from these invisible light waves supplies much of the solar heat that determines the earth's weather. Astronomers use slight, variations in the sun's ultra-violet spectrum as clues to the chemical and physical reactions goingon at various depths in the sun. By comparing satellite measurements of invisible radiation with earth-bound records of the sun's visible light, scientists should be able to predict some of these reactions and their effects on earth...
