There is no such thing as society: there are individual men and women, and there are families.

The history of mathematics is a testament to the ingenuity and creativity of the human mind.

Doing the best at this moment puts in the best place for the next moment.

有时候你必须先迷失自己，才能有所发现。

能源的未来在于我们持续适应和创新的能力。
