“The theoretical physicist Richard Feynman was such a lauded lecturer in large part because, like Hui Tzu, he was skilled in finding the right analogies to illustrate his explanations of extremely abstract-and extremely difficult-concepts. He once compared a drop of water magnified 2,000 times to “a kind of teeming... like a crowd at a football game as seen from a very great distance.” That description has all the precision of good physics and good poetry.”
