The man with the big ideas wasn't so good with the details. In Einstein's Mistakes: The Human Failings of Genius (W.W. Norton, $24.95, excerpted below), Hans Ohanian writes that Albert often let his intuition overrule flawed proofs and shaky math. Maybe you'll feel a little better about your own flubs.
