"There's certain kinds of men in every field that I can talk to as well as I can talk to a good scientist...If you give me the right man in any field, I can talk to him. And I know what the condition is: that he did whatever he did as *far* as he can go. That he studied every aspect of it as far as he can go--that he has stretched himself to the edge. He's not a dilettante in any way. And therefore he's up against mysteries all the way around the edge. Mystery and awe--we can talk about mystery and awe. That's what we have in common." --Richard Feynman
