事实是，最多人的最大幸福是衡量对与错的标准。
The said truth is that it is the greatest happiness of the greatest number that is the measure of right and wrong.
The development of science cannot be separated from innovation and cooperation.
If you're not stubborn， you'll give up on experiments too soon. And if you're not flexible， you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.
追求幸福是一种徒劳的努力；真正的满足在于接受。
If you don't give up, you still have a chance. Giving up is the greatest failure.
