Electrodynamics — Quantum

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

Beyond being a mathematical masterpiece, QED provided the blueprint for the of particle physics. It showed scientists how to combine quantum mechanics with special relativity and successfully handle "renormalization"—a mathematical technique to remove the "infinities" that previously broke earlier theories. Quantum Electrodynamics

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. Developed by Richard Feynman, these are visual tools

An electron emits or absorbs a photon at a specific place and time. Why It Matters Developed by Richard Feynman
