科学必须是世界上的一股善的力量。
Each generation takes the earth as trustees.
It wasn't only wickedness and scheming that made people unhappy, it was confusion and misunderstanding; above all, it was the failure to grasp the simple truth that other people are as real as you.
That’s been one of my mantras—focus and simplicity.Simple can be harder than complex，you have to work hard to get your thinking clean to make it simple.
The best scientists are those who remain humble in the face of nature's complexity.
