major contribution to physics
Extended and Deepened our Understanding of the Weak Force
According to modern physics, there are four fundamental forces in nature. Electromagnetic interaction is one of these. The weak interaction, responsible for e.g. the beta-decay of nuclei is another. With theoretical contributions by Abdus Salam, Sheldon Glashow and Steven Weinberg in 1968, these two interactions were unified to one single, called electroweak. The theory envisaged e.g. so called weak neutral currents in certain interactions of elementary particles, an effect later confirmed in experiments.
