Feynman diagram

n.
A diagram used in quantum electrodynamics and quantum chromodynamics to help describe and visualize the possible interactions between particles. Fermions are represented with straight lines, and bosons with wavy lines. Points of intersection indicate an interaction between the particles.

[After Richard Phillips Feynman.]

It explains the basic physics and formalism of the theory, helps students become proficient in perturbation theory calculations using Feynman diagrams, and introduces gauge theories that are playing a central role in elementary particle physics.
Perhaps the finest grained evidence here comes from the work of David Kaiser, who has traced the flow of ideas among physicists, looking at the development, mutations, and spread of Feynman diagrams.

Physics is not just an aimless, random sequence of Feynman diagrams and symmetries, and mathematics is not just a set of messy equations, but rather physics and mathematics obey a definite symbiotic relationship.
Feynman's scientific work (his path-integral formulation of quantum mechanics, his contributions to quantum electrodynamics and the ubiquitous Feynman diagrams, his work on liquid helium and on the structure of nucleons) is also skillfully treated.
