Quantum Chromodynamics (QCD)

The video tutorial by Professor Dave explains quantum electrodynamics and its role in describing the electromagnetic force through quanta, specifically virtual photons. It introduces the concept of quarks, their varieties, and their role in forming protons and neutrons. The tutorial delves into quantum chromodynamics, explaining the color charge of quarks and the strong nuclear force mediated by gluons. It highlights the complexity of quantum field theories, which require multiple particles for different forces, and concludes with the need to understand and categorize new particles introduced by quantum theory.
