"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
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"
The Thomson Reuters forecast for the Physics Nobel prize was completely wrong! :) And so was mine, but I think, in my defense, I didn't predict the graphene discovers will win it this year. I just think that they will win it some time soon, and as the importance of graphene emerges even more, then the discovery will be even more significant.
BTW, it is interesting to note that I highlighted recently issues regarding spontaneous symmetry breaking as the origin of mass. With this Nobel prize, and with the LHC looking for the Higgs, it clearly underlines the importance of the understanding of such symmetry breaking as one of the most fundamental aspect of our universe.
