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.
