2008 Nobel Prize in Physics breaks symmetry

The 2008 Nobel Prize in Physics relates to broken symmetry discoveries which led to the quark model.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2008 with half to Yoichiro Nambu of the Enrico Fermi Institute, University of Chicago, IL, USA "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics" and the other half jointly to Makoto Kobayashi, High Energy Accelerator Research Organization (KEK), Tsukuba, Japan and Toshihide Maskawa,Yukawa Institute for Theoretical Physics (YITP), Kyoto University, Japan "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature".
