过去不在我们身后，而在我们之内。

In science, the only constant is change.

The world is changed by your example, not by your opinion.

译文：有德行的人不会去炫耀自己的长处，有修养的人是不会去夺取别人喜欢的东西。赏析：不要随便议论别人的缺点，切莫夸耀自己的长处。做人低调不张扬，才不会引起别人的嫉妒和报复。别人喜欢的东西，不要一心想占为己有。

Every seed planted is a vote for the kind of world we want to live in.

沉默可以是一种强大的抵抗形式。

Every artist dips his brush in his own soul, and paints his own nature into his pictures.

生命的历史是转化的历史。
