化学是物质的科学，但我更愿意将其视为变化的科学。

我认为如果你做了某件事，结果还不错，那么你应该去做其他精彩的事情，不要停留太久。只要弄清楚下一步是什么。

Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.

一个人最危险的敌人是他自己的口舌。

记住，希望是好事，甚至也许是人间至善。而美好的事永不消失。
