A Feynman diagram is a graphical method created by physicist Richard Feynman to visualize and calculate the interactions between fundamental particles, such as electrons and photons. These diagrams use different lines to represent different particles (straight lines for fermions, wavy lines for bosons) and depict interactions as points where lines meet. By applying a set of simple rules to each diagram, physicists can determine the probability of a particular particle collision, with each diagram representing a family of possible interactions that contribute to the total outcome.
