追求数学真理是一项既个人又普遍的努力。

引用李希贵

The only purpose for which power can be rightfully exercised over any member of a civilized community， against his will， is to prevent harm to others.

在一个数据结构上运行100个函数比在10个数据结构上运行10个函数要好。

Every stroke of the brush carries the weight of history and the lightness of possibility.

可持续性不是一种选择；它是我们星球未来的必需品。
