If you have no idea what this diagram is about, well, in theoretical physics, Feynman diagrams are pictorial representations of the mathematical expressions describing the behavior of subatomic particles. The scheme is named after its inventor, American physicist Richard Feynman, and was first introduced in 1948. Feynman diagrams are used by physicists to make very precise calculations of the probability of any given process, such as electron-electron scattering, for example, in quantum electrodynamics. The calculations must include terms equivalent to all the lines and all the vertices shown in the diagram. You can see that in the following diagrams.

A Feynman diagram represents a perturbative contribution to the amplitude of a quantum transition from some initial quantum state to some final quantum state. For example, in the process of electron-positron annihilation the initial state is one electron and one positron, the final state: two photons. The initial state is often assumed to be at the left of the diagram and the final state at the right (although other conventions are also used quite often). A Feynman diagram consists of points, called vertices, and lines attached to the vertices. More diagrams are in the following images.

To understand how one electron influences another, using Feynman diagrams, you have to imagine that the electrons, as they move through space and evolve in time, exchange a photon, here labeled “virtual quantum.” This is the simplest possibility. It is also possible to exchange two or more photons, and Feynman made similar diagrams for that. These diagram contribute to all of it, and you can freely save and print them all by clicking on the images!
