"The only real failure in life is not to be true to the best one knows."

科学最有价值的部分是看到你的工作帮助他人。

语出（南宋）崔敦礼《刍言》。自以为聪明的人，其实并不聪明；自以为能干的人，其实并不能干。

To succeed， get other people to pay you； to become wealthy， help other people to succeed.

Sustainability must be at the core of every stone we extract, or we extract nothing at all.
