Five months ago, U.S. negotiators struggling to achieve an agreement with the Russian scientists on a detection system for atomic explosions were thrown into confusion. Tests had shown that underground explosions could not be detected so far away as had been thought, but the Russians refused to increase the number of detection stations the U.S. had first proposed. Since then, U.S. efforts have been directed at discovering means to improve the sensitivity of detection with the stations proposed. Last week, as negotiators prepared to resume the suspended talks at Geneva, word leaked of a report submitted to President Eisenhower which...
Storm Trouble. The most sensitive way to detect distant earthquakes-or underground atomic explosions-is by measuring the long waves that travel along the earth's surface instead of striking deep into its interior. Drawback to this method is that even such minor disturbances as a storm at sea set up shorter surface waves (microseisms) that obscure or blot out the record. The Lamont improvement is an ingenious filtering device that separates earthquake waves from local confusion...
Pomeroy and Sutton are guarded about the effect their filters will have on international networks for detecting underground nuclear tests. They calculate that six stations equipped with the new instruments could detect most underground disturbances anywhere on earth that have the energy of a "nominal" (20-kiloton) nuclear bomb. Between 20 and 50 stations (v. the presently postulated 180) would be required not only to detect but also locate such disturbances. They are not prepared to estimate just how many more would be required to detect explosions of bombs as small as 5 kilotons or how accurately they could distinguish...
Briefly, his commitment is to find moral and, more especially, monetary support for Algerian students, who have been chased from the University of Algiers, deprived of French Government scholarships in France, persecuted, arrested, and forced underground. The Student Union headquarters is now in Lausanne, Switzerland. Its proselytizing leaders are totally dependent upon NSA, WUS, and other student organization funds. This has been the case since 1954, when the Algerian student community declared its unanimous support of the nationalist insurrection...
...partner while remaining strictly Kiesler. Their collaboration resulted first in Manhattan's strange and elegant World House Galleries (TIME, Feb. 4, 1957). Now ground is being broken for the partners' full-scale project at the Hebrew University of Jerusalem: a gigantic shrine, to be entered from underground, and built around an 80-foot column of c water, to house the Dead Sea Scrolls...
