Water Flight. Last summer the committee (backed in part by the National Science Foundation) called in some 100 physicists, science writers and high school teachers, turned out an integrated text supplemented by ingenious do-it-yourself equipment (TIME, July 29). Throughout, the committee tightly knit together its subject material; e.g...
Died. Edward Asbury O'Neal, 82, onetime (1931-47) president of the American Farm Bureau Federation, influential voice in the shaping of New Deal farm policies, key figure (with Henry A.

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.
In his 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...
¶Knock out the costly short-term acreage reserve phase of the soil bank and build up the long-term conservation reserve to encourage the retirement of marginal farm land from production for up to ten years.
