Feynman Rules

Feynman Rules are a set of guidelines used in quantum field theory to calculate the behavior of particles and their interactions. Developed by physicist Richard Feynman, these rules help physicists translate complex mathematical expressions into visual diagrams, known as Feynman diagrams. Each element in these diagrams represents a particle, and their connections illustrate how particles interact or exchange forces. By following these rules, scientists can systematically compute the probabilities of various outcomes during particle collisions and other quantum processes, ultimately enhancing our understanding of fundamental forces in nature.
