The first one:19101012. Hua was born in Jintan County, Jiangsu Province. He comes from a poor family and is determined to study hard. When I was in middle school, in a math class, the teacher gave the students a famous question: "There is a number, three places, and two;" 5 digits, 5 numbers, and the remaining 3; There are seven places in seven, and there are two left. What's the number of this? " While everyone was thinking, Hua stood up and said, "23". His answer surprised the teacher and won his praise. From then on, he fell in love with mathematics. After finishing the first grade of junior high school, Hua dropped out of school because of his poor family, so he had to stand in front of the counter for his parents, but he still insisted on teaching himself mathematics. Through his unremitting efforts, his paper "Why can't the solution of Su Jiaju's algebraic quintic equation be established" was discovered by Professor Xiong Qinglai, head of the Department of Mathematics of Tsinghua University, and invited him to Tsinghua University; Hua was hired as a university teacher, which is unprecedented in the history of Tsinghua University. 1In the summer of 936, Hua, an outstanding mathematician, was a visiting scholar at Cambridge University in England for two years. At this time, the news of the Anti-Japanese War spread all over Britain, and he returned to the motherland with strong patriotic enthusiasm to give lectures for The National SouthWest Associated University. China attaches great importance to the direct application of mathematical methods in industrial and agricultural production. He often goes deep into factory guidance, popularizes the application of mathematics and writes popular science books. Hua has also set a shining example for young people to become self-taught. He is a self-taught mathematician without a college degree. He said: "I am not afraid of difficulties and study hard. This is my main experience in learning mathematics well." "The so-called genius is to rely on unremitting efforts. 1930 One day, Xiong Qinglai, head of the Department of Mathematics at Tsinghua University, was sitting in his office reading a science magazine. Looking at it, I can't help but exclaim: "Which country is this China from?" Everyone around shook their heads. "Which university does he teach at?" People looked at each other. Finally, a Jiangsu-born teacher thought for a long time before slowly saying, "My brother has a classmate named Hua. Which university did he teach at? " ! He only went to junior high school and heard that he worked as a clerk in Jintan Middle School. "Xiong Qinglai by surprise. A person who graduated from junior high school must be a genius to write such a profound mathematical paper. He immediately decided to invite Hua to Tsinghua University. Since then, Hua has become a teaching assistant in the Department of Mathematics of Tsinghua University. Here, he is like a duck to water, swimming in the ocean of mathematics every day, leaving only five or six hours of sleep for himself. It's hard to believe that flowers have developed the habit of reading books after turning off the lights. Of course, he has no special function, just a logical thinking activity in his mind. He took a book and put it under the lamp, looked at the topic and thought for a while, then turned off the lamp and lay in bed, closed his eyes and meditated, and began to do the problems in his mind. Turn over and get out of bed when you encounter difficulties, and open your books for a while. In this way, a book that took ten days and a half months to finish, he finished it in one night and two nights. Hua is regarded as a rare assistant. The following year, his papers began to be published in famous foreign mathematical magazines. Tsinghua University broke the precedent and decided to promote Huawei teaching assistants with only junior high school education. A few years later, Hua was sent to Cambridge University in England to study. However, he doesn't want to study for a doctorate, but only wants to be a visiting scholar. Because being a visiting scholar can break through the shackles and learn seven or eight subjects at the same time. He said, "I came to study in Britain, not to get a degree. "China didn't get a doctorate. During his two years in Cambridge, he wrote 20 papers. On the level, every article can get a doctorate. In one of the studies on "the problem in the tower", his theory was named "Fahrenheit theorem" by the mathematical community. Hua devoted himself to his favorite mathematical research with the spirit of loving science, being diligent in research and not seeking fame and fortune. He abandoned the money, fame and position that the world sought. In the end, his career succeeded. China closely combines scientific research with practical application. Hua applied mathematics to industrial and agricultural production and made outstanding contributions to China's modernization. When Gauss, a great mathematician, was a child, the teacher asked the students to calculate the sum from 1 to 100. The students are all working hard, and Gauss has worked it out. The teacher asked him how to calculate. He told the teacher that 1 plus 99 is 100, and 2 plus 98 is 100, which makes 50 hundred, and 50 plus 50 is 50.
