Japan's Makoto Kobayashi receives the 2008 Nobel Prize in Physics from Sweden's King Carl XVI Gustaf (R) at the Concert Hall in Stockholm December 10, 2008. The physics prize was awarded to three scientists with Kobayashi and Toshihide Maskawa of Japan sharing one half "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature", and Yoichiro Nambu of the U.S. winning one half "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics".
