David Gross

David Gross is a renowned theoretical physicist best known for his work in quantum chromodynamics (QCD), which is the field of physics that describes the strong force that holds atomic nuclei together. His groundbreaking contributions in the 1970s helped to deepen our understanding of how quarks and gluons—the fundamental particles that make up protons and neutrons—interact. Gross, along with his colleagues, introduced the concept of asymptotic freedom, which explains that quarks interact more weakly at higher energies. This discovery was pivotal in establishing the framework of particle physics and earned him the Nobel Prize in 2004.
