Steven Weinberg

Steven Weinberg 1933-, American nuclear physicist, b. New York City, Ph.D. Princeton Univ., 1957. He helped develop important theories of electromagnetic and nuclear particle interaction that were experimentally verified in 1982-83 when Carlo Rubbia and Simon van der Meer identified the subatomic particles W and Z. In 1979, Weinberg shared the Nobel Prize in Physics with Abdus Salam and Lee Glashow .

Weinberg, Steven (1933– ) US physicist who in 1967, independently of Pakistani physicist Abdus Salam, proposed a theory that unified the electromagnetic and weak nuclear forces between subatomic particles – now known as the electroweak force. Later experiments proved the Salam-Weinberg hypothesis to be true. In 1979, they shared the Nobel Prize in physics with Sheldon Glashow, who had earlier proposed a similar theory.
