The only way to do great work is to love what you do.

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

The pen is mightier than the sword if the sword is very short, and the pen is very sharp.

唯一有价值的东西是你无法买到的东西。

Trust the scientific process—it’s slow but it works.

Every tree planted today is a legacy for future generations.

科学思想不像被分成越来越小的蛋糕，而像一棵不断分枝的树。
