Understanding Quantum Electrodynamics
Quantum electrodynamics (QED) describes the interaction between light and matter, serving as a fundamental theory in quantum physics. It focuses on the behavior of charged particles, particularly electrons, and their interactions with photons, the particles of light. A significant achievement in QED was addressing the challenge of infinities in early quantum field theories through a technique called renormalization, developed by Richard Feynman and his colleagues. This advancement not only resolved previously nonsensical infinite values but also enhanced physicists' ability to make accurate predictions about electromagnetic interactions.
