In mathematics, truth is somewhere out there in a place we don’t yet know, and the only way we can hope to find it is by exploring.

I remember my friend Johnny von Neumann used to say, 'with four parameters I can fit an elephant, and with five I can make him wiggle his trunk.'

"The truth is rarely pure and never simple."

I'm interested in what happens when things fall apart.

The best predictions come not from complex models, but from understanding fundamental incentives.

我不是来追求完美的。我是来做真实的自己。
