Feynman diagrams of every second-order S-matrix element of the QED perturbation theory. Lines with up-arrow denote to electrons overlapped by their vacuum-particles and lines with down-arrow denote to positrons overlapped by their vacuum-particles. Lines with a circle denote to vacuum-particles of Dirac fields. Wave lines denote to photons overlapped by their vacuum-photons and wave lines with circles denote to vacuum-photons.

Fans of particle physics often encounter a series of doodles called Feynman diagrams. These mystifying scribbles were invented by Richard Feynman and they en.

Feynman diagram - In this diagram, a kaon, made of an up and anti-strange quark, decays both weakly and strongly into three pions, with intermediate steps involving a W boson and a gluon (represented by the blue sine wave and green spiral, respectively).

A Feynman diagram representing electron-electron scattering, which requires summing over all the possible histories of the particle-particle interactions.

Feynman diagram:Scattering process A + B → C + D: •internal lines (red) 4 intermediate particles & processes, w/propagator factor ("prop"), external lines (orange) 4 incoming/outgoing particles 2/from vertices (black), •at each vertex there's 4-momentum conservation using delta functions, 4-momenta entering vertex R (+) & leaving R (-), factors at each vertex & internal line R multiplied in amplitude integral,•space x & time t axes Rn't always shown, directions of external lines=passage of…

Feynman Diagrams. «Lo que hacemos para tener la respuesta a este problema es análogo a lo que tenemos que hacer para tener la respuesta a cualquier otro problema explicado por la electrodinámica cuántica. Prepárense para enfrentarse con ello, no por que sea difícil de entender, sino por que es absolutamente ridículo: Todo lo que hacemos es dibujar pequeñas flechas en una hoja de papel».

This is a simple Wallpaper featuring Feynman diagrams. This diagrams are used in physics to illustrate easily particle interactions. Some time ago I read that Feynman himself has a van all covered .

Great introduction to particle physics by learning to draw Feynman diagrams.

Theoretical physics at its simplest -- it works. Complex doesn't have to be complicated.
