The fine-tuning of the universe is shown in the precise strengths of four basic forces. Gravity is the best known of these forces, and the weakest, with a relative strength of 1. Next comes the weak ...

Nuclear physics is a research area focused on the structure, dynamics, and interactions of atomic nuclei and their constituent nucleons, governed primarily by the strong and weak nuclear forces within ...
