George Zweig

George Zweig is an American theoretical physicist known for his significant contributions to particle physics. In the 1960s, he proposed the "quark model," suggesting that protons and neutrons are not elementary particles but are made up of smaller particles called quarks. This idea helped explain the structure of matter and the strong nuclear force that binds atomic nuclei together. Zweig's work, alongside similar theories by others, revolutionized our understanding of fundamental particles, leading to the development of Quantum Chromodynamics, which describes the interactions of quarks and gluons, the force carriers of the strong force.
