This year's Nobel Prize in physics (worth $42,606) went last week to two professors of the University of California at Berkeley, Emilio Segre, 54, and Owen Chamberlain, 39. In 1955 they headed a team that found the long-sought antiprotons, key particles of the stranger-than-fiction world of antimatter (TIME, Oct. 31, 1955 et seq.). Antiprotons, which the Segre-Chamberlain team identified in a beam of subatomic debris created by Berkeley's 6.2-billion-volt bevatron, have the mass of ordinary protons but carry negative electric charges instead of positive charges. When a proton hits an antiproton, they annihilate...
