Weinberg, Steven

▪ American physicist
born May 3, 1933, New York, N.Y., U.S.

      American nuclear physicist who in 1979 shared the Nobel Prize for Physics with Sheldon Lee Glashow (Glashow, Sheldon Lee) and Abdus Salam (Salam, Abdus) (qq.v.) for work in formulating the electroweak theory, which explains the unity of electromagnetism with the weak nuclear force.

      Weinberg and Glashow were members of the same classes at the Bronx High School of Science, New York City (1950), and Cornell University (1954). Weinberg went from Cornell to the Nordic Institute for Theoretical Atomic Physics in Copenhagen for a year and then obtained his doctorate at Princeton University in 1957.

      Weinberg proposed his version of the electroweak theory in 1967. Electromagnetism and the weak force were both known to operate by the interchange of subatomic particles. Electromagnetism can operate at potentially infinite distances by means of massless particles called photons, while the weak force operates only at subatomic distances by means of massive particles called bosons. Weinberg was able to show that despite their apparent dissimilarities, photons and bosons are actually members of the same family of particles. His work, along with that of Glashow and Salam, made it possible to predict the outcome of new experiments in which elementary particles are made to impinge on one another. An important series of experiments in 1982–83 found strong evidence for the W and Z particles predicted by these scientists' electroweak theory.

      Weinberg conducted research at Columbia University and at the Lawrence Berkeley Laboratory before joining the faculty of the University of California at Berkeley in 1960. During part of his last two years there, 1968–69, he was visiting professor at the Massachusetts Institute of Technology; he joined its faculty in 1969, moving to Harvard University in 1973 and to the University of Texas at Austin in 1983.
