Richard Feynman was very active in research while teaching at Caltech.  One of the well known colleagues he collaborated with at Caltech was Murray Gell-Mann.  The flare for the dramatic he incorporated into his teaching style was also present in his work as a researcher.  Here is a story about Richard Feynman presenting on his discovery with Gell-Mann of the V-A model of weak interactions as written by a former student, Anthony Hey.

"Another stow that circulated was of Feynman giving a talk about the discovery, with Gell-Mann, of the V - A model of weak interactions. After the talk, a person in the audience came up to him and said, "Excuse me, Professor Feynman, but isn't it usual in giving a talk about joint research to mention the name of your collaborator?"Feynman reportedly came back with: "Yes--but it's usual for your collaborator to have done something!""

This diagram is an example of a Feynman Diagram.  Richard Feynman came up with these diagrams as a sort of conceptual and mathematical shorthand to describe the interactions of particles.  Each line represents something: The straight lines represent particles (electrons, positrons, etc.).  The interactions occur where the lines intersect.  The wave represents a photon being either emitted or absorbed.  These diagrams were used as Feynman looked into Quantum Electrodynamics.  In 1965, he was awarded the Nobel Prize for his work in this field.
