t at the summer school in 1960, he began to study the literature on symmetry and symmetry breaking, examin- ing the work of Nambu, Goldstone, Salam, Weinberg, and Anderson. Higgs became depressed by the seemingly hopeless task of reconciling Goldstone's theorem with the possibility of massive Yang-Mills

etical physics. It took several centuries or, if one counts back to the science of the Greeks, several millennia of hits and misses to come up with the Standard Model. So this is where we are. Are great new experimental insights just around the corner that may validate, or invalidate, some of the grander specula
