The Lone Genius Hypothesis

[T]here are times when I sit alone in my office and scribble equations. There are times when I sit outside and stare and think. But, to be honest, those times are usually not especially productive. When I really make progress, when I really have breakthroughs — those are always times when I’m talking to other physicists and astronomers, chewing through new ideas and checking that I’m on the right track. And even more often, the most important work we do is what grows organically from our conversations or e-mails or paper perusals.
