The Nobel Prize in Physics 2004
Born: 15 May 1951, New York, NY, USA
Affiliation at the time of the award: Massachusetts Institute of Technology (MIT), Cambridge, MA, USA
Prize motivation: "for the discovery of asymptotic freedom in the theory of the strong interaction."
Prize share: 1/3
The atomic nucleus is held together by a powerful, strong interaction that binds together the protons and neutrons that comprise the nucleus. The strong interaction also holds together the quarks that make up protons and neutrons. This interaction is so strong that no free quarks have ever been observed. However, in 1973 Frank Wilczek, David Gross, and David Politzer came up with a theory postulating that when quarks come really close to one another, the attraction abates and they behave like free particles. This is called asymptotic freedom.
Their work and discoveries range from the Earth’s climate and our sense of touch to efforts to safeguard freedom of expression.
