...field of science and education, the University cannot risk being out-shone by the Nobel Prize Committee and will therefore grant a degree to Chen Ning Yang, present Loeb Lecturer in Physics here and one of the young Columbia professors who upset the Law of Parity last fall...
...massive extirpation force netted and scatter-gunned the exhausted birds or snared them with long, gum-tipped bamboo poles. At last report 310,000 sparrows had fallen in Peking alone, and an estimated 4,000,000 throughout the rest of Red China. The national hero was Yang Seh-mun, 16, of Yunnan. He had killed 20,000 sparrows by sneaking around during the day locating nesting trees. At night, China Youth proudly reported, he then climbed trees and strangled whole families of sparrows with his bare hands...
Chen Ning Yang, professor of Physics at the Institute for Advanced Study at Princeton, described the events leading to his Nobel Prize-winning discovery of the non-conservation of parity at the first Morris Loeb Physics Lecture yesterday...
...lecture, "The Role of Symmetry in Physics," Yang showed the relation between his discovery and parallel examples in physics where the discovery of "symmetry" and "invariance" in a system led to a law of conservation within the system. He cited conservation of linear momentum and the conservation of angular momentum as examples...
...Yang theorized that if the definition of "parity" were extended to include the substitution of an "anti-particle" for a particle, in addition to the mirror image of the particle's physical position, symmetry would be conserved and the so-called law of parity would be valid. The experiment is not feasible, however, because not enough "anti-material" is obtainable, he said...
