化学是一门一直贴近我内心的科学，我以喜悦和热情将一生奉献给了它。
——2004年在南京航空学院上的演讲
The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes.... Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.
释义：美丽的彩云容易消散，明亮的圆月难得圆满。
You have to be ready to suffer and enjoy suffering.
