That was my thought too. I was hoping for some Feynman-esque discussion on what it means to truly understand something: "It’s not quite true that Feynman could not accept an idea until he had torn it apart. Rather, the idea could not yet be part of his way of thinking and looking at the world. Before an idea could contribute to that worldview, Feynman wanted to turn over the idea, to see why it was true, from any angle that he could find. In other words, he wanted to connect a new idea to what he already understood and thereby extend his understanding" (http://www.freakonomics.com/2011/04/08/how-richard-feynman-thought/ http://www.freakonomics.com/2011/04/08/how-richard-feynman-t...).
