...nuclear explosions. The scientists should aim for an initial progress report in 30 days, a final report in 60 days, wrote Ike, and the U.S. and U.S.S.R. should keep the U.N. fully informed of progress. Then the President nominated three topflight U.S. scientists to represent the U.S. The three: Physicist Ernest 0. Lawrence, director of the University of California's Radiation Laboratory; Bell Telephone Laboratories' Executive Vice President Dr. James Brown Fisk; Caltech Physicist Robert F. Bacher, onetime member of the U.S. Atomic Energy Commission...
Cosmic Radiation. Space's swirling storms of atomic particles cause mutations (mostly undesirable for survival) in bread mold, probably will have the same effect in humans if they strike the genes in the reproductive system. Unsuspected until this month's report by Iowa Physicist Dr. James Van Allen was the intense radiation storm encountered 600 miles from the earth by Explorer satellites. Still to be learned is whether this danger zone stretches from pole to pole. If so, the space traveler may have to hurry through it, as Dr. Simons says, "like running fast through a grass fire...
Furthermore, tutorial for credit does not offer every capable student desiring to do independent work the same opportunities as would free study under the course reduction program. The physicist who would like to take time out to study a certain literary epoch, or the English major who might want to do a project outside his field cannot study in his own department's tutorial. Tutorial for credit is, also, essentially a graded course, and the student may feel less free to explore interesting sidelines to his work if he feels pressure to earn a high grade...
Last week, in the British publication, Nature, Florida State University Physicist Philip J. Wyatt suggested one possible clue: "Of the many craters on the earth known to have been produced by fallen meteors, a few have left no signs of the meteor which caused them, apart from the huge holes created in the earth's crust." Could antimatter possibly have been involved? If so, says Wyatt, "no traces of the meteors would remain, due to the annihilation process." Best example is the huge meteor that blazed over southern Russia on the morning of June 30, 1908. Minutes later...
...Physicist Wyatt suggests another search at the site for short-lived radioisotopes, produced by intense gamma radiation, which could prove the point. One theoretical flaw in the argument is that an antimatter meteor ought to explode shortly after whizzing into the earth's atmosphere. Moreover, anti-gravity may be a property of antimatter. Unlike other meteors, which fall into the earth's gravitational field, an antimatter meteor would be repelled. But if antimatter does not have antigravity, an antimatter meteor - if big enough to survive the annihilation of its surface - might hit the earth...
