Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.

想到自己可能成为从世界上消除最大灾难之一的工具，同时怀有享受独立、家庭和平与幸福的希望，这种喜悦常常如此强烈，以至于在草地上研究我喜爱的课题时，我有时会陷入一种遐想。

I never write Metropolis for seven cents because I can get the same price for city. I never write policeman because I can get the same money for cop.

我旅行得越多，就越确信世界上充满了我们尚未发现的奇迹。
