最终,我们只会后悔没有抓住的机会。
In the end, we only regret the chances we didn't take.
Chemistry is the art of manipulating matter at the molecular level, and catalysis is its most powerful brush.
这是最幸运的年代,也是最倒霉的年代,这是智慧的年代,也是愚昧的年代;这个时期信仰与怀疑共存,这个时期光明与黑暗共存;这是希望之春,也是失望之冬;人们面前琳琅满目,但又一无所有;我们正直达天堂,我们正直通地狱。
Virtue is more to be feared than vice, because its excesses are not subject to the regulation of conscience.
