英国女王伊丽莎白二世来华访问时想见他，他说

平静：不要被琐事、普通或者不可避免的事所扰。

The chemical industry is the backbone of modern civilization, and we must treat it with the respect and responsibility it deserves.

【译文】 孔子说：“对品德不进行培养，对学问不进行钻研，听到好人好事不能跟着做，有了错误不能及时改正，这就是我所担忧的。”

What is freedom of expression? Without the freedom to offend, it ceases to exist.
