A scientific man ought to have no wishes, no affections, a mere heart of stone.  

真正的学者不在于知识渊博，而在于热爱真理并真诚追求。

I’ve always believed that you should never, ever give up and you should always keep fighting even when there’s only a slightest chance.

Do not let your fire go out, spark by irreplaceable spark.

成功的唯一方法是努力工作，永不放弃。
