Did Einstein applaud these brave new developments? Not even close. Although his sacred intuitions had gotten him pretty far, these ideas violated his sense of how nature must work, and he loathed them. Here Mr. Ferreira shows us an Einstein we don't see often—a petulant and petty man, someone not above using his celebrity to squash "ugly" ideas. And, boy, he made some blunders. When Georges Lemaître, a Belgian cosmologist and priest, laid out the first evidence for an expanding universe, Einstein groused that, "although your calculations are correct, your physics is abominable." Eventually, Einstein's intransigence pushed him to the margins of general-relativity research, and he accomplished virtually nothing in the last decades of his life.
