...scientific celebrity and adventurer, he finds zest in teaching, mountain climbing, fishing and in trying a new flavor of ice cream, no less than in exploring the complicated structure of chlorophyll and in helping develop nuclear fission. He has the great capacity for growth that is the essence of the educated man. And his own breadth of intellectual interest is the essence of 310-year-old Harvard, whose motto is the single Latin word Veritas (Truth...
...toughest science brushup course of all time, Teacher Conant should be in good form. As chairman of the National Defense Research Committee he exercised absolute dictatorial powers over men and materials in its $2 billion wartime research program, developing radar, antiradar, various new chemical warfare wrinkles-and nuclear fission. Conant's job was as an organizer, moderator and catalyst, but he would have failed if he had not been a topnotch scientist...
These radiations are not peculiar to atomic bombs. They are also produced by the controlled chain reaction in a uranium pile or atomic power plant. The reaction itself generates powerful gamma rays and floods of neutrons. The uranium disintegrates, leaving a residue of highly active fission products. The neutrons, wandering through the pile, the cooling system and the concrete shield, stir up radioactivity. The pile may become "poisoned," and everything from it, or in contact with it, must be shunned like death...
...deadly serious historical fact. MARCH OF TIME, with the cooperation of 20-odd scientists, who appear in the picture, has retraced and re-enacted the main publishable stages in its cause and towards its possible cure. The motion in charts and animation makes newly graphic the basic principles of fission; shots heretofore unreleased to the screen suggest some of the effects, including, as one emblem or symbol more grim than any in Pompeii, the shadow of a human body, fire-stenciled into the pavement of Hiroshima...
...would also need equipment for: 1) removing the pile's "ash" (fission products), which slows down the chain reaction and eventually stops it altogether; 2) periodic repurifying of the uranium in the pile; 3) making repairs by remote control in case the battleship's engine broke down...
