Quantum Electrodynamics (QED)

The video explores quantum electrodynamics (QED), focusing on the transition from classical field forces to particle interactions. Richard Feynman's work on virtual photons is highlighted, explaining how electromagnetic forces result from particle exchanges rather than fields. The video introduces Feynman diagrams as a tool to represent these interactions and discusses the integration of QED with special relativity. The conclusion hints at future developments in quantum field theories.
