...Theta Puzzle. Last summer two daring theorists, both of them Chinese, challenged parity. Professors Tsung Dao Lee of Columbia and Chen Ning Yang of the Institute for Advanced Study in Princeton were visiting Long Island's Brookhaven National Laboratory, whose pleasant summer climate and massive equipment attract vacationing physicists from all over the country. A leading topic at bull sessions, some of them held alfresco on Westhampton Beach, was the "tau-theta puzzle," which many leading physicists have been trying manfully to crack since...
Most physicists tried vainly to solve the tau-theta puzzle in a way that preserved parity. Showing less respect for scientific propriety, Drs. Lee and Yang suggested last summer at Brookhaven that perhaps the trouble lay not with the K mesons but with parity itself. If parity could be violated on occasions, the odd behavior of the K mesons would be easy to explain...
Chilled Cobalt. In brilliantly reasoned papers Lee and Yang showed that it should be possible to get along without parity. They also suggested ways to test experimentally whether parity is really a basic principle of nature. By this time the whole world of theoretical physics was watching Lee and Yang, and the best facilities in the U.S. were offered for testing their theory...
While other physicists puzzled over this evidence, Tsung Dao Lee of Columbia University and Chen Ning Yang of the Institute for Advanced Study proposed that the long sacred principle may be invalid. Recently completed experiments at Columbia have justified their assertion...
...also of court painters and poets still ranked among China's greatest. Among the period's leading figures : the Empress Wu, who rivals Britain's first Elizabeth for energy and cunning; the "Illustrious Sovereign" Hsuan-Tsung, scholar and educator, whose tragic love for the beauteous Yang Kuei Fei ended when the army, incensed at her extravagance, forced her to be hanged from a pear tree with a silken scarf...
