It’s like the story that’s apocryphally attributed to Niels Bohr, a Nobel Prize–winning physicist. A friend of his was visiting his office and kept looking up at the horseshoe over the door. Finally, he could no longer contain his curiosity. Could it really be that a mind as remarkable as Bohr’s believed that horseshoes brought luck? Of course he didn’t believe it, Bohr replied. “But I understand it’s lucky whether I believe in it or not.”
