...weak" forces were labeled to resolve a separate contradiction--the curious, so-called "beta-decay" of certain nuclei. Thus, if Einstein's unified field theory was to be vindicated, all these forces had somehow to be reconciled--proven to be aspects of the same force...
...Weinberg, 46 (U.S.), and Abdus Salam, 53 (Pakistani), for their contributions to a theory that explains the relationship of two of nature's basic forces: 1) electromagnetism, which accounts for such phenomena as sunlight and radio waves, and 2) the weak force that governs the release of a beta particle from the nucleus of an atom in a process called radioactive decay...
Another question lingered: Was the leaking truly dangerous? Though radioactive, tritium is a hydrogen isotope emitting only low-energy beta particles that cannot penetrate uncut skin. If ingested, tritium may mix with body chemicals, but no biological damage has ever been proven. That ambiguity did not trouble state officials. "If a person breathes in tritium, it doesn't have to be strong to do harm," contends Ken Geiser, acting director of the Arizona atomic energy commission...
Harling said the MIT reactor studies beta and gamma particles themselves, rather than using them for energy, and its reactor produces only one-600th of the wattage of a commercial plant...
...Organization for Women (NOW) in 1977, doubled the membership to 100,000 and raised dues and contributions from $700,000 annually to $2.6 million. The first housewife to head NOW, as well as its first full-time paid president, Smeal is a native of Erie, Pa., and a Phi Beta Kappa from Duke University. She discovered feminism
