Quantum — Electrodynamics

Developed by Richard Feynman, these are visual tools used to calculate the probability of particle interactions. Lines represent particles, and "vertices" represent where they meet and exchange energy. Licensed by Google Three Basic Actions

In QED, the electromagnetic force isn't a "static" field, but rather an exchange of photons . When two electrons repel each other, they are effectively "tossing" photons back and forth. Quantum Electrodynamics

is the relativistic quantum field theory that describes how light and matter interact. It specifically focuses on the interactions between electrically charged particles (like electrons and positrons) and the electromagnetic field (represented by photons). The "Jewel of Physics" Developed by Richard Feynman, these are visual tools

QED is often called the most successful theory in the history of science because its predictions match experimental results with incredible precision—comparable to measuring the distance from New York to Los Angeles within the width of a human hair. Core Principles When two electrons repel each other, they are
