Feynman diagrams are graphical representations used in quantum electrodynamics (QED) to illustrate the interactions between particles, such as electrons and photons. They serve as a visual tool to simplify complex calculations in particle physics, depicting processes like particle collisions and decays. The diagrams represent various elements, including particles, their interactions, and the exchange of force carriers. Resources like the provided links offer detailed explanations and educational videos featuring Richard Feynman discussing QED and the significance of these diagrams. Understanding Feynman diagrams is essential for grasping the underlying principles of quantum field theory.
