...seismic inspection stations. On the basis of the five-kiloton report, the U.S. settled down with the Russians at Geneva to try to negotiate a stop-tests agreement with an inspection and detection system-but fully aware that the chances of detection were slim below the five-kiloton underground threshold...
...even as the negotiators were talking, the U.S. Atomic Energy Commission was totting up results of the October series of underground blasts at Yucca Flat, Nev. The results were enough to curl the scientists' hair: instead of a five-kiloton threshold, the real minimum underground blast that could be fully detected was about 20 kilotons-about the size of the Nagasaki-Hiroshima bombs. Science Advisory Committee Chairman James Rhyne Killian Jr. broke the news to President Eisenhower before Christmas, and the U.S. expects to break it to the Russians at Geneva this week. Next soul-searching question: Should...
Oberlin's 2,300 students are above-average bright-61 of this year's 450 freshmen were first in their high school classes-and apt to be complacent about it. Said one recent graduate: "We loved to remind each other that our average IQ approached the threshold of genius." Most Oberlin people go on to graduate school, do especially well in the sciences. Equalitarian Oberlin bans automobiles, and although almost every student pedals a bicycle, the hot spots of Cleveland-and Elyria-are out of effective range. But high spirits burst out, sometimes beerily. Night climbing expeditions have...
...strange fruit have raised a vigorous progeny. His free form can today be found in Palm Springs swimming pools, advertising layouts, book design. His use of chance effects and nonrational promptings paved the way for abstract artists' use of below-the-threshold impulses. But of one thing he is certain: "If the human being loses contact with nature, if there are no longer any trees, it is the end of the world. Machines, Sputniks, I find them horrible, ridiculous. The human being has become presumptuous...
...believe that current nuclear-bomb fallout accounts for between 400 and 2,000 leukemia cases a year (total: 150,000), as compared to 15,000 from natural radiation. Science is not yet sure how much radiation is needed to produce leukemia. The U.S. National Academy of Sciences estimates the threshold as 40 rem. If this is true, and if all bomb tests stop this year, said the U.N. report, then the ultimate total of fallout leukemia cases would be between 25,000 and 150.-000. (But should the threshold be as much as 400 rem. probably no leukemia cases could...
