"Fear is the mind-killer."

I hope it will not be long before we have a machine that will be able to solve all mathematical problems.

艺术家必须是神秘的孩子。

引用自海明威《老人与海》，张海迪在演讲中多次引用以表达坚韧精神

You think it will never happen to you, that it cannot happen to you, that you are the only person in the world to whom none of these things will ever happen, and then, one by one, they all begin to happen to you, in the same way they happen to everyone else.
