我喜歡這部根據Sylvia Nasar撰寫的同名傳記體，而拍成的關於數學家John Forbes Nash的電影，這確實是一部感人至深的電影。

John Forbes Nash是一個天才的數學家，然而他卻患有精神分裂症。Nash在博弈論和微分幾何學領域潛心研究，最終獲得諾貝爾經濟學獎，這誠然與他的天才，智慧和努力分不開的。

然而影片最令我感動的是Nash的妻子Alicia Larde，她忍受著常人難以想象的痛苦，不離不棄，自始自終地地陪伴著Nash：一個介於天才和瘋子之間的數學家，是多麽的不容易呀。

我特別喜歡納什被授予諾貝爾獎時，對他的妻子Alicia發表的這段深情而又理智的感言，摘錄如下，和大家分享。

“I've always believed in numbers. In 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 logical reasons can be found. I'm only here tonight because of you. You are the reason I am. You are all my reasons. Thank you.

我一直相信數字，方程式，邏輯推理。但是經過一生的追尋後，我問我自己，什麽才是正確的邏輯，誰決定的前提？

我從肉體上，精神上，幻覺上探索這個問題，再回到現實。然後我發現了生涯中最重要的發現，我一生中最重大的發現，就是在愛情中，任何邏輯都是合理的。隻因有你，我今晚才能站在這裏。你是我成其為我的前提，你是我所有的邏輯。謝謝。”

 

A beautiful mind《美麗心靈》(二)這個片斷也非常有趣，在這個片斷裏，Nash以誰能得到金發美女，這個形象的方式博弈導出了自己的理論，非常的生動。我摘錄如下：《請點擊欣賞電影：A Beautiful Mind（二）》

“John: If we all go for the blonde, we block each other. Not a single one of us is gonna get her. So then we go for her friends, but they will all give us the cold shoulder, because nobody likes to be second choice.

Well, what if no one goes for the blonde? We don't get in each other's way, and we don't insult the other girls. That's the only way we win. That's the only way we all get laid.

Adam Smith said the best result comes from everyone in the group doing what's best for himself, right? That's what he said, right?”

Nash這段形象的解釋，讓我想起了Albert Einstein對他的相對論的形象的解釋，和你分享。

Put your hand on a hot stove for a minute, and it seems like an hour.

Sit with a pretty girl for an hour, and it seems like a minute. That's relativity
－－Albert Einstein.

不得不感歎，天才就是能把複雜的理論簡單化。
