The Standard Model

The Standard Model is a fundamental theory in physics that describes the basic building blocks of matter and the forces that govern their interactions. It includes particles like quarks and leptons, which make up protons, neutrons, and electrons. Quantum Electrodynamics (QED) is a part of this model that explains how light and matter interact through the exchange of photons. Overall, the Standard Model helps us understand the universe at a subatomic level, providing a framework for the electromagnetic, weak, and strong nuclear forces while demonstrating the unity of these fundamental interactions.
