Who is trying to "tear him down"? All I see is people trying to point out the differences between "Richard Feynman the character" and "Richard Feynman the real person" "Richard Feynman the character" would talk about how he goes to parties and is able to befuddled people in their native languages that he doesn't speak. "Richard Feynman the person" was a nobel prize winning physicist Do his tall tales have to be true for his nobel prize to be valid? Or can he be lying for his ego while still being a good scientist?
