What's the main field Julian Schwinger is known for?
Quantum Mechanics
Biology
Quantum electrodynamics
Astrophysics
Answer
Quantum electrodynamics (QED) is a relativistic quantum field theory that describes the behavior of electromagnetic interactions in physics, especially between electrically charged particles. Developed in the 1940s by physicists including Julian Schwinger, it successfully merged the principles of quantum mechanics and classical electromagnetism, explaining phenomena such as the behavior of electrons in an electromagnetic field and the emission and absorption of photons.
