在四月一日时，回想一下这一年来的其他364天自己在做些什么。

That there are things in this world not carved out of gray stone. That there s a small place inside of us they can never lock away, and that place is called hope.

"In science, the credit goes to the man who convinces the world, not to the man to whom the idea first occurs."

宇宙越是显得可理解，也就越是显得无意义。
