The Feynman Diagram is a graphical representation of particle interactions in quantum field theory developed by Nobel Prize-winning physicist Richard Feynman. It is used to visualize and calculate the probability of a particular interaction between particles, and is a powerful tool for understanding the behavior of subatomic particles
From Wikipedia
In theoretical physics, a Feynman diagram is a pictorial representation of the mathematical expressions describing the behavior and interaction of subatomic particles. The scheme is named after American physicist Richard Feynman, who introduced the diagrams in 1948.
