美丽心灵(A Beautiful Mind)

    １９９４年度的诺贝尔经济学奖，授予美国普林斯顿大学数学系的纳什教授等三位对博弈论作出奠基性贡献的学者。好莱坞大制作《美丽心灵》A Beautiful Mind说的就是纳什的故事。

    写的是一个叫纳什的天才。纳什在三十岁之前就已经成为数学界响当当的人物，可是却在三十岁之后得上了严重的精神分裂症。这时学界开始出现了一大堆以纳什命名的术语，什么纳什均衡、纳什程序、纳什谈判解、纳什嵌入等，可是这时的纳什已经从学界消失，所以引用他文章的青年数学家、经济学家都以为他已经死了。他当然没有死，他只是得了精神分裂，整天在普林斯顿闲逛，在黑板上写一些奇怪的符号，偶尔也会露一露天才的本相，或者发布他收到的外星智慧发给他的最新密码。

    由于纳什夫人的爱心的呵护，他的病情终于逐渐逐渐好转，最后于1994年获得诺贝尔奖。本演讲是影片中纳什领取诺贝尔奖时候的致辞。

演讲全文：1994 Nobel Prize in Economic Sciences Acceptance Address

Nash: Thank you. I've always believed in numbers and the equations and logics that lead to reason.

But after a lifetime of such pursuits, I ask, "What truly is logic? Who decides reason?"

My quest has taken me through the physical, the metaphysical, the delusional -- and back.

And I have made the most important discovery of my career, the most important discovery of my life: It is only in the mysterious equations of love that any logic or reasons can be found.

I'm only here tonight because of you [his wife, Alicia].

You are the reason I am. You are all my reasons.

Thank you.
