John F. Nash Jr 乔治.纳什

I had studied international economics and business as my major in college,got a bachelor's degree in ECONOMICS.but i don't think i have got the basic knowledge and the theories.Even though,I knew the name of the greatest economist John Nash and his game theory at class.

Some years later,I watched the movie"A Beautiful Mind",moved by his experience.(sorry for i can't explain my thoughts well in english) I found the speech when he got the Nobel Prize in 1994.Hope you enjoy it.http://nobelprize.org/nobel_prizes/economics/laureates/1994/nash-autobio.html
