...Carbon Atom," Professor Kohler, Mallinckrodt MB22...
...Steel "seems to have mellowed, and, if one may say so, he seems more human [than three years ago]. During the previous interview I was particularly struck by the low tonelessness of M. Stalin's voice - as if he felt the need of conserving every atom of energy for his gigantic task. Now he shows more animation and less restraint...
Universe. Belgium's Abbe Georges Lemaitre, astronomer and relativist, once thought of the universe as cosmic shrapnel -fragments still receding violently from the explosion billions of years ago of a single primordial atom. In Pasadena last winter he explained to a respectful listener named Albert Einstein how this picture accounted for cosmic rays (TIME, Jan. 23). One dilemma his picture did not resolve. The observed rate of recession of the farthest visible parts was so fast (12,000 to 15,000 mi. per sec.) that it made the universe seem unreasonably young. Last week, backed by intricate mathematics...
...discrepancy between the spectrographic and chemical calculations of the weight of the hydrogen atom suggested that there must be a rare isotope of hydrogen mixed with the abundant common hydrogen found in water and sugar. Such an isotope would behave chemically like hydrogen, but weigh two, perhaps three times as much. Professor Raymond Thayer Birge of the University of California and Professor Donald Howard Menzel of Harvard calculated that one part of heavy hydrogen should appear in 4,500 parts of ordinary hydrogen...
...recent, rapid discoveries of particles in the atom have sent physicists back to their Greek dictionaries. Hydrogen No.1 (most common) is beginning to be called protium, Hydrogen No. 2 deuterium. Hydrogen No. 3 will therefore have to be tritium. Protium's nucleus is the proton, deuterium's the denton, and tritium's (probably) the triton. After them, in Nature's system of elements, comes helium (atomic weight approximately 4). The helium atom's nucleus is the alpha particle which, in the full round of substances, again appears during the disintegration of the heaviest...
