数学家的模式，就像画家或诗人的模式一样，必须是美丽的；思想，就像颜色或文字一样，必须以和谐的方式结合在一起。
The mathematician's patterns, like the painter's or the poet's, must be beautiful; the ideas, like the colors or the words, must fit together in a harmonious way.
The beauty of language lies in its ability to convey the inexpressible.
最微小的善行也比最宏大的意图更有价值。
We must balance the need for energy today with the imperative of protecting the planet for tomorrow.
我不害怕死亡，我只是不想在那一刻在场。
