Feynman Diagrams are visual representations used in quantum field theory to illustrate the interactions between particles. Named after physicist Richard Feynman, these diagrams simplify complex calculations by depicting particles as lines and their interactions as points where lines meet. Each line represents a particle, while vertices indicate interactions, such as collisions or decays. These diagrams help physicists understand and predict the behavior of subatomic particles, like electrons and photons. By translating mathematical equations into graphical form, Feynman Diagrams make it easier to analyze processes in particle physics, contributing significantly to our understanding of the fundamental forces of nature.
