# Feynman and his diagram Barnebys

Particle Astrophysics Second Edition - SINP

The diagram illustrated above represents the interaction of two electrons. Each electron is represented by a straight line, which exchange a (virtual) photon and then repel one other. Feynman-like diagrams for photon/electron interaction and electron recollision. 6. Feynman diagram for attractive forces.

6. Feynman diagram for attractive forces.

It depicted the simplest contribution to an electron-electron interaction, with a single virtual photon (wavy line) emitted by one electron and then absorbed by the other. Feynman diagrams can also be used to describe the weak interactions, which are mediated by the W+, W− and Z0 bosons, rather than the photon. This is illustrated by Fig. 5, which shows the dominant contributions to the elastic scattering reaction Sign in to download full-size image FIGURE 5. Feynman Diagrams Decoded. This diagram shows three basic actions. The first, a photon goes from place to place, is illustrated by the line from 5 to 6. The second, a n electron goes from point A to point B in space-time, is illustrated by the lines from 1 to 5, 5 to 3, 2 to 6, and 6 to 4.

That is the regime physicists call “weak coupling,” where each
Feynman relied heavily on verbal communication, such as when he used cartoonish diagrams to explain highly scientific principles. Feynman could easily tap into complex ideas using shapes, lines, and drawings.

Each electron is represented by a straight line, which exchange a (virtual) photon and then repel one other.

In an old story familiar to philosophers of science and technology, tools such as Feynman diagrams not only shaped the practices of those inside the workshop but also came to be taken for granted and seemingly transparent avenues to what appears to be the “real”. Through the work of Feynman, Dyson, Julian Schwinger and Sin-Itiro Tomonaga, a new and improved theory of quantum electrodynamics was born. Feynman’s lines and squiggles, which became known as Feynman diagrams, have since “revolutionized nearly every aspect of theoretical physics,” wrote the historian of science David Kaiser in 2005. The Meaning of Feynman Diagrams Michael H. Seymour School of Physics and Astronomy, University of Manchester, and Theoretical Physics Group (PH{TH), CERN Abstract Feynman diagrams are often used as a ‘cartoon’ to explain the physics process being studied in a particular reaction.

The American theoretical physicist Rich-ard Feynman first introduced his diagrams in the late 1940s as a bookkeeping device for simplifying lengthy calculations in one area of physics—quantum electrodynamics, or QED, the quantum-mechanical description of elec-tromagnetic forces. Soon the diagrams gained Fourth, Feynman diagrams transformed what physicists conceived as real. In an old story familiar to philosophers of science and technology, tools such as Feynman diagrams not only shaped the practices of those inside the workshop but also came to be taken for granted and seemingly transparent avenues to what appears to be the “real”. Feynman diagrams are a technique to solve quantum ﬁeld theory.
