Caltech's H. David Politzer won the Nobel Prize in Physics for a discovery he shared with two other scientists while a grad student at Harvard—in 1973. The version that is safe for normal brains is that the discovery of "asymptotic freedom" explains how quarks are bound together to form the protons and neutrons of atomic nuclei. Like any good professor of theoretical physics based in Hollywood, Politzer portrayed physicist Robert Serber in Fat Man and Little Boy, the 1989 film starring Paul Newman that recounted the story of the Manhattan Project. He is Caltech's 30th laureate.
