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. 

Chronology of Einstein’s Mistakes

  5. 1905 Mistakes in the relationship between thermal radiation and quanta of light

  6. 1905 Mistake in the first proof of E = mc2

  7. 1906 Mistakes in the second, third, and fourth proofs of E = mc2

  17. 1919 Mistakes in two attempts to modify general relativity

  18. 1925 Mistakes and more mistakes in the attempts to formulate a unified theory

  19. 1927 Mistakes in discussions with Bohr on quantum uncertainties
