There is a gem of an article by Stephen Wolfram titled “A Short Talk About Richard Feynman.”
I found these comments from that article very interesting:
“I think Feynman—at least in the years I knew him—was much more driven by the pure pleasure of actually doing the science. He seemed to like best to spend his time figuring things out, and calculating. And he was a great calculator. All around perhaps the best human calculator there’s ever been.”
“And often he’d come up with one of those classic Feynman straightforward-sounding explanations. And he’d never tell people about all the calculations behind it. Sometimes it was kind of a game for him: having people be flabbergasted by his seemingly instant physical intuition. Not knowing that really it was based on some long, hard calculation he’d done.”
“You know, in many ways, Feynman was a loner. Other than for social reasons, he really didn’t like to work with other people. And he was mostly interested in his own work. He didn’t read or listen too much; he wanted the pleasure of doing things himself.”
“One thing about Feynman is that he went to some trouble to arrange his life so that he wasn’t particularly busy—and so he could just work on what he felt like.”
“One of the things he often said was that “peace of mind is the most important prerequisite for creative work.” And he thought one should do everything one could to achieve that. And he thought that meant, among other things, that one should always stay away from anything worldly, like management.”
Stephen Wolfram recommends that we read Richard Feynman’s collected letters.
