Excerpt: Feynman diagrams refer to a pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles. The calculation of probability amplitudes in theoretical particle physics requires the use of some rather large and complicated integrals over a large number of variables. These integrals do, however, have a regular structure, and may be represented graphically as Feynman diagrams. A Feynman diagram allows for a simple visualization of what would otherwise be a rather arcane and abstract formula. More precisely, a Feynman diagram is a graphical representation of a perturbative contribution to the transition amplitude or correlation function of a quantum mechanical or statistical field theory. Within the canonical formulation of quantum field theory a Feynman diagram represents a term in the Wick's expansion of the perturbative S-matrix. Alternatively, the path integral formulation of quantum field theo...
