Feynman diagram

Noun

Feynman diagram (plural Feynman diagrams)

1. A pictorial representation of the interactions of subatomic particles, showing their paths in space and time as lines, and their interactions as points where lines meet.
   • Feynman diagrams for the fourth-order radiative corrections to the scattering of an electron by an electromagnetic field.1950 February 15, Robert Karplus, Norman M[yles] Kroll, “Fourth-order Corrections in Quantum Electrodynamics and the Magnetic Moment of the Electron”, in Physical Review, volume 77, number 4...
   • The symbolic representation of Maxwell's equations is introduced to make it easier to survey the whole subject and to formulate the equations. The Feynman diagram method is applied to the computation of the correlation of the fields at different points in space to any order of approximation.1967 April 3, Betty L.
