There are two great mysteries about the beach. One is why human beings flock there by thousands, only to prostrate(俯卧) themselves in dense packs of glistening flesh. The other is why the sand goes there. Strange as it seems, oceanographers have never really understood why sand piles up on the shore.

"If you take a very aloof look at a beach," says Inman, "you’ll realize that if the two motions move sand back and forth the same amount, then all the sand should end up in
