because he thinks only Gene Salamin can solve it. Can any of you? (who didn't already know the answer) For a ceremonial match, a soccer ball is colored with a map of the Globe instead of a traditional pattern. At the start of the match, the ball rests on its south pole, with its lat 0, long 0 point aimed due east. At the end of the match, the ball lies forgotten on the pitch, in a truly random orientation. For any orientation, there will always be an axis through the center about which a single rotation will restore the original north up, 0,0 east orientation. What is the (surprising) expected magnitude of this required rotation? And yet last week Gary ran (with great satisfaction) Julian's tympanhedron, which, to my knowledge, has *never* been found when posed as a puzzle. --rwg
