Gell-Mann's contributions to the Standard Model

Murray Gell-Mann was a physicist who made key contributions to understanding the fundamental building blocks of matter. He proposed the quark model, revealing that protons and neutrons are composed of smaller particles called quarks, which helped unify the way we classify particles. His work introduced concepts like quantum numbers and symmetries that are central to the Standard Model, the framework describing fundamental particles and forces (except gravity). Gell-Mann's insights provided clarity on how particles interact and grouped, shaping the modern understanding of particle physics.
