A Feynman diagram is a type of graph used to represent the interactions between subatomic particles.

Feynman diagrams have time on the y-axis and space on the z-axis.

Feynman diagrams are used to simplify complex equations used to represent subatomic particle interactions.


This Feynman diagram shows the electromagnetic interaction between two protons via the virtual photon.	This Feynman diagram shows the weak interaction in which a neutron decays into a proton. <math>n \xrightarrow{W^-} p + \beta^- \bar\nu<math>
