Quantum electrodynamics: theory

The Standard Model of particle physics is composed of several theories that are added together.  The most precise component theory is the theory of quantum electrodynamics or QED.  In this video, Fermilab’s Dr. Don Lincoln explains how theoretical QED calculations can be done.  This video links to other videos, giving the viewer a deep understanding of the process.
