Known for his contributions to the field of theoretical physics , he was awarded half of the Nobel Prize in Physics in 2008 for the discovery in 1960 of the mechanism of spontaneous broken symmetry in subatomic physics , related at first to the strong interaction 's chiral symmetry and later to the electroweak interaction and Higgs mechanism .
