——《在沪举办茶话会上的演说》（1916年7月17日）

在科学中，失败不是成功的对立面，而是通向成功的垫脚石。

Writing is a way of speaking without being interrupted.

The world needs more scientists who think like engineers, and more engineers who think like scientists.

My blindness is not a tragedy, but an opportunity to see the world in a different way.

当今天下的士人君子,内心果真想行仁义之道,做上等的贤士,上要符合圣王之道,下要符合国家与百姓的利益。
