G·H·哈代受到了打扰,因为这位著名的剑桥大学数学家刚刚收到一个名叫斯里尼瓦桑·拉马努詹的印度人来信。他自称已经发现了120个数学定理,并请哈代对其进行考证。哈代经常收到一些幻想家的来信,他们声称已经解决了所有的问題,看来此人也一样。哈代不耐烦地浏览了一下信的内容。许多定理看上去毫无道理,而且其中有一 G.H. Hardy was disturbed because the famous Cambridge mathematician had just received a letter from an Indian named Srinivasan Ramanughan. He claimed to have discovered 120 mathematical theorems, and asked Hardy to carry out research. Hardy often received letters from some visionaries who claimed they had solved all the problems. Hardy impatiently browsed the contents of the letter. Many theorems seem unreasonable, but one of them
