Hua (19 10- 1985), a world-famous mathematician, was the vice president of China Academy of Sciences. Foreign newspapers once introduced China as follows: "His research scope is wide enough to make him one of the top mathematicians in the world." "So, which university did he graduate from?" If you ask, the answer will surprise you: he only went to junior high school and never went to college! His success depends on tenacious and diligent self-study. Hua used to be a naughty boy, but he was very talented in mathematics. Once, the math teacher worked out a famous math problem in ancient China-there was one thing, I don't know how many. Three places and three places, with a surplus of 2; 5 digits, 5 numbers, and the remaining 3; Seven numbers of seven, leaving two. How much is this thing? After the topic came out, the students talked about it, and no one could tell. The teacher was about to speak when Hua raised his hand and said, "I have worked it out." It is 23. " Not only did he get the numbers right, but the algorithm was also very special. This surprised the teacher greatly. However, the clever boy dropped out of school after finishing middle school because his family was poor. He returned home and did business in his small grocery store, selling cigarettes, needle and thread, etc., and shouldered the burden of bringing home the bacon for his father. However, Hua still loves mathematics. If you can't go to school, try to learn by yourself. On one occasion, he borrowed some math books from his teacher, and became fascinated when he saw them. From then on, he studied mathematics while doing business and accounting. Sometimes he is so absorbed in reading that he forgets to say hello when people buy things. In the evening, after the shop closed, he wandered around the kingdom of mathematics wholeheartedly. For a whole year, I spent more than ten hours studying the borrowed math books almost every day. Sometimes when I sleep until midnight and think of a solution to a difficult math problem, he will definitely turn over, light a small oil lamp and write down the solution. At this time, he got typhoid fever. He stayed in bed for half a year and finally recovered his life, but his left foot was disabled for life. In the midst of poverty and disease, Hua still devoted all his energy to mathematical research, and published several important papers in succession, which attracted the attention of Professor Xiong Qinglai of Tsinghua University (which we will talk about in Xiong Qinglai's story). From 65438 to 0932, with the help of Professor Xiong Qinglai, Hua went to the Mathematics Department of Tsinghua University and became an administrator. He wants to do a few things by himself, but he continues to teach himself courses, and he also teaches himself English and German, so he can write papers in English.
