this guy is one of the best-cited physicists in history, but has he done anything besides the inflationary theory? is he a one-hit wonder? another uhlenbeck / goudsmit?

i was always thoroughly unimpressed with inflationary theory, like video related below. but at least alan was smart enough not to go off the deep end like linde. anyhow, just wondering, has guth done anything outside the realm of his 1980 paper?
