Yoichiro Nambu was awarded the 2008 Nobel Prize in Physics "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics".

Nambu 'has revolutionized modern scientific ideas about the nature of the most fundamental particles and the space through which they move. His theories form an essential cornerstone of what physicists call the Standard Model, which explains in a unified way three of the four fundamental forces of nature: strong, weak and electromagnetic. He also has significantly influenced the development of quantum chromodynamics, a theory that describes certain interactions between quarks and between protons and neutrons.' 1

'Dr. Nambu, a U.S. citizen, is the Harry Pratt Judson Distinguished Service Professor Emeritus in Physics at the University of Chicago and its Enrico Fermi Institute. …

Over a period of three decades starting in the 1960s, the Atomic Energy Commission, a DOE predecessor agency, and the U.S. Department of Energy supported Dr. Nambu … .' 2
