Richard Feynman on QED

Uh ... yeah.  What he said.

Only after watching all of this did I discover it was not an explanation of how Keynesian economic theory works.  It is instead physicist Richard Feynman warning his students that they won't understand what he's going to tell them, because he doesn't either.  I think that if someone memorized selections from this,  they could use it successfully in just about any situation, from job  interviews to court appearances. But not in a debate with Friedrich Hayek.
