Quark
The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. Quarks were introduced as parts of an ordering scheme for hadrons, and there was little evidence for their physical existence until deep inelastic scattering experiments at the Stanford Linear Accelerator Center in 1968. Accelerator experiments have provided evidence for all six flavors. The top quark, first observed at Fermilab in 1995, was the last to be discovered.
University of Cambridge
In physics, Ernest Rutherford who is regarded as the father of nuclear physics, spent much of his life at the university where he worked closely with E. J. Williams and Niels Bohr, a major contributor to the understanding of the atom, J. J. Thomson, discoverer of the electron, Sir James Chadwick, discoverer of the neutron, and Sir John Cockcroft and Ernest Walton, responsible for first splitting the atom. J. Robert Oppenheimer, leader of the Manhattan Project that developed the atomic bomb, also studied under Rutherford and Thomson. Joan Curran devised the 'chaff' technique during the Second World War to disrupt radar on enemy planes.
Astronomers Sir John Herschel, Sir Arthur Eddington, Paul Dirac, the discoverer of antimatter and one of the pioneers of quantum mechanics; Stephen Hawking, theoretical physicist and the university's long-serving Lucasian Professor of Mathematics until 2009; and Lord Martin Rees, the current Astronomer Royal and former Master of Trinity College. John Polkinghorne, a mathematician before his entrance into the Anglican ministry, received the Templeton Prize for his work reconciling science and religion.
