"Maybe you can afford to wait. Maybe for you there’s a tomorrow. Maybe for you there’s one thousand tomorrows, or three thousand, or ten, so much time you can bathe in it, roll around it, let it slide like coins through your fingers. So much time you can waste it. But for some of us there’s only today. And the truth is, you never really know."

Mathematics is the music of reason.

诗歌始于愉悦，终于智慧。

创新不仅仅是技术的问题，更是思维方式的问题。
