Under the plans "the School of Education would move into the Radcliffe Yard and some of Radcliffe's functions would move into the dormitory area. Now if this should occur, then the Observatory Hill land would go to Radcliffe for use as dormitory sites," he said...
...arms race goes on as it has, we are left to ponder not if, but when, a nuclear war will occur. Our choice is between great change and great ruin. In order to survive we have either to avert an attack or to shield ourselves from its effects. Since anti-missile defense does not exist, protection means going underground in shelters. Secret reports to the President have urged this sort of "passive defense;" a well-known atomic scientist recommends it on television; and Herman Kahn has recently dedicated a book to the idea...
...declining international prestige and wonder why. We of this country realize you have a color problem, but so have we, as we are outnumbered 100 to 1. Even so, I have never seen a European here vent childlike emotions on a small native child. That such a thing can occur in the U.S.A. is sufficient evidence of the immaturity of the people concerned to cause us grave doubts of the fitness of the U.S.A. to be a bulwark against Communism...
Strategic Waters. In deciding how to employ its carrier, Brazil's navy had been influenced by a little-publicized but increasingly effective U.S. drive aimed at mobilizing the hand-me-down ships of South America's navies. If war should occur, the U.S. Navy's sub hunters will need all the help they can get. During World War II, German U-boats sliced into the shipping lanes, even managed to cut off Brazil's northeast bulge from Rio except by heavy Allied convoy. The new danger is Soviet Russia's fleet...
Even low-intensity tones can be dangerous if they are pure, i.e., if their frequency is limited. The reason: pure tones form a concentration of sound energy within the ear. The most "sensitive" frequencies-those which the body can least tolerate-occur, says Dr. Knudsen, within the octaves of 300-600 cycles per sec. and 600-1,200 cycles (middle C is 261.6 cycles). Warns Dr. Knudsen: "Anyone who lives in an environment where the intensity at these frequencies consistently reaches 85 decibels [for example, alongside a busy jet airport] should have hearing tests-because damage is possible...
