每天的下午茶时分,在普林斯顿大学数学系大楼的休息厅里,可以见到一个头发灰白、双眼深陷、不时在一张纸上潦草地写写画画的人.看着他,很难想象这个30年前就看似行将就木并一直生活在贫困中的人,是一位数学天才、诺贝尔奖得主. Every day during the afternoon, at Princeton University’s Department of Mathematics building lounge, you can see a gray hair, eyes deep, from time to time in a scribbled on a piece of paper to write people who draw. Looking at him, it is difficult to imagine The 30-year-old man who seems to be on the verge of living and has lived in poverty is a mathematical genius and Nobel laureate.
