I think what you're talking about is what Feinman describes as follows: When you're thinking about something you don't understand, you have a terrible uncomfortable feeling called Confusion. It's a very difficult and unhappy business. And so most of the time, you're rather unhappy, with this Confusion, you can't penetrate this thing. Now the Confusion is because we are all some kinds of apes that are kind of stupid working against this... trying to put the two sticks together to reach the banana, and we can't quite make it yet, the idea. And I get that feeling all the time - that I'm an ape trying to put the two sticks together, so I always feel stupid. Once in awhile, though, the sticks go together on me and I reach the banana. [1] Everyone is terrified of feeling stupid, of being perceived as stupid. Only the most brave among us have enough courage to admit our collective stupidity and go out and learn something. 1. http://video.google.com/videoplay?docid=3164300309410618119#1m22s http://video.google.com/videoplay?docid=3164300309410618119#...
