Work

According to modern physics, four fundamental forces exist in nature. Electromagnetic interaction is one of these. The weak interaction-responsible, for example, for the beta decay of nuclei-is another. Thanks to contributions made by Steven Weinberg, Sheldon Glashow, and Abdus Salam in 1968, these two interactions were unified to one single, called electroweak. The theory predicted, for example, that weak interaction manifests itself in "neutral weak currents" when certain elementary particles interact. This was later confirmed.
