*Edit***Feynman Diagram**. Feynman's represent the interaction between sub-atomic particles. Graphs are a set of vertices and a set of edges where an edge is a pair of vertices.

Feynman diagrams are a technique to solve quantum eld theory. Hence a typical Feynman diagram in the QED Feynman perturbation series induced by this Discussion of Feynman diagrams in the rigorous formulation of causal perturbation theory and. They represented a deep shift in thinking about how the universe is put together.

### Physicists have used Feynman diagrams as a tool for calculating scattering amplitudes that describe particle interactions for more than six decades.

English: A Feynman diagram is a representation of quantum field theory processes in terms of particle paths. The momenta going along the internal lines are determined by the fact that mom netum is conserved at each vertex.
