[glăsh′ō]Sheldon Lee Born 1932
American physicist who developed one of the first theories of an electroweak force, unifying two of the four fundamental forces of nature-the electromagnetic force and the weak force-as two aspects of a single underlying force. He developed the theories of Abdus Salam and Steven Weinberg by introducing a new particle property known as charm, and for this work he shared with Salam and Weinberg the 1979 Nobel Prize for physics.
