The mind， both in so far as it understands， and in so far as it imagines， is passive.

生命是一段旅程，享受过程。

To do mathematics is to engage in an act of creation and discovery simultaneously.

Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider.

成功不在于成为最大的，而在于产生最大的积极影响。

世界不是一个需要解决的问题；它是一个我们所属的生命体。
