Jerome Friedman, Institute Professor emeritus and one of a team of physicists who proved that quarks are real, said in his 2001 Killian Lecture that while the battle of the quark is over, the next step was to learn more about the particle’s structure. Professor Friedman shared the 1990 Nobel Prize in Physics for “pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics.” More at MIT News
