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. In the 1960s, a unified theory was formulated for these two forces: the electroweak interaction. However, certain problems still remained to be solved. In the early 1970s, Gerardus t'Hooft and Martinus Veltman formulated and tested a mathematical theory that further explained the electroweak interaction.
