John Nash,a Nobel Prize winner and a mathematical genius whose struggle with mental illness was documented in the Oscar-winning film A Beautiful Mind,was killed in a car accident on May 24th, 2015.
Born in West Virginia, Nash displayed a keenness for mathematics early in life,independently proving Femret's little theorem(定理)before graduating from high school. By the time he turned 30 in 1958,he was an unquestionable academic celebrity. At Princeton, Nash published a 27-page thesis that led to applications to economics,international politics, and evolutionary biology
His signature solution-known as a "Nash Equilibrium(纳什均衡)”-found that competition among two opponents,not necessarily governed by zero-sum logic. Two opponents can, for instance,each achieve their maximum objectives through cooperating with the other, or gain nothing at all by refusing to cooperate. It is now regarded as one of the most important social science ideas in the 20th century.
In the late 1950s, Nash began a slide into mental illness. By the time Nash was awarded the Nobel Prize in Economics in 1994, he hadn't published a paper in 36 years. But like a child cured of a nightmare by the switch of a light, Nash recovered from his illness seemingly by choosing not to be sick anymore. He continued to work, travel,and speak at conferences for the rest of his life.
In 2001,the release of the film A Beautiful Mind,based an Sylvia Nasar’s 1998 book of the same name,introduced Nash's unusual life story to an international audience

In the winter vacation, I paid a visit a mountain village in a suburb of Luoyang. No sooner had I got off the bus when I was greatly surprising to see all the changes. It was far better than I had been expected. Now every family can drink cleanly running water. The villagers needn’t carry water himself any more. Firewood is no longer used for cooking. Marsh gas, a new cheap clean energy, make it very convenient to cook and light. As all the families have color TV set, they can enjoy plays at home. It impressed me most was that the best building in a village was the school. I hope the mountain village will become better and better.
