...Born was a physicists' physicist. As head of the University of Gottingen's prestigious Institute of Theoretical Physics in the pre-Nazi era, he was one of the pillars of the flourishing German scientific community. A brilliant teacher, he attracted many of the great names of the atomic era-Oppenheimer, Teller, Fermi-to Göttingen's lecture halls and laboratories. Equally communicative outside the university, he produced a flood of books and essays to unravel the complex new physics for an uncomprehending public. But Born, who died in Göttingen last week...
...Subtlety. By the early 1920s, investigations into the atom had struck an impasse. The old Newtonian laws could explain such motions as those of the planets around the sun; they could not account for the subtle behavior of electrons whirling around the nucleus of an atom. Trying to work their way out of this quandary, Born and other scientists held that the motion of the electron was discontinuous or broken into pockets of energy called quanta. Others conceived of electrons as continuous, uninterrupted waves. Though these theories helped explain atomic phenomena, they could not tell physicists where an individual electron...
Slowdown at Sunrise Governed by the natural rhythm of an isotope of the cesium atom-which vibrates exactly 9,192,631,770 times per second-the atomic clock has long been considered man's most accurate timekeeper. Calculated to gain or lose less than a second over a period of 6,000 years, it was adopted by the 1967 General Conference of Weights and Measures as the international time standard. Despite those impressive credentials, which are accepted by most scientists, the reliability of the clock has now been questioned by two experimenters at the U.S. Naval Research Laboratory...
