悲伤不是一条线，让你无限远离失去。它是一个圆，你会一次又一次回到同一个地方。
"Grief is not a line, carrying you infinitely further from loss. It is a circle, and you come back, again and again, to the same place."
我们必须继续推动科学可能性的边界，为了人类的进步。
The truth is, I don't know what I'm doing. But I know I'm doing it with all my heart.
我们都是自己过去的幽灵，徘徊在我们曾经熟悉的地方。
The future belongs to those who can balance economic growth with environmental protection.
幸福取决于我们自己。
