我喜欢把数学看作一种诗歌。

我们不能用制造问题时的同一水平思维来解决问题。

城市就像一张巨大的重写羊皮纸，几个世纪以来被反复书写和重写。

For me they normally happen, these career crises, often, actually, on a Sunday evening, just as the sun is starting to set, and the gap between my hopes for myself and the reality of my life starts to diverge so painfully that I normally end up weeping into a pillow.

在有限的生命里，你必須去挑战伟大。
