Chemistry is the art of manipulating matter at the molecular level, and catalysis is its most powerful brush.
化学是在分子水平上操纵物质的艺术，而催化是其最强大的画笔。
Whatever you fight, you strengthen, and whatyou resist, persists.
The most powerful tool for change is knowledge, rigorously pursued and widely shared.
I don't rap for dead presidents. I'd rather see the president dead.
翻译：君主不应该因为发怒而兴兵，将领也不应该因为发怒而出战。符合国家利益就行动，不符合国家利益就停止。愤怒可以转变为欢喜，恼怒也可以转为喜悦，但国家灭亡了就不能再建立，人死了就不能复活。
我相信善良和同情的力量。
