Modern mathematician and scientist in China. 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: "I don't know what the number is today, whether the number of three plus three is greater than two, whether the number of five plus five is greater than three, and whether the number of seven plus seven is greater than two." What is the geometry of things? " 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." Hua is also a mathematics educator, who has trained a large number of outstanding mathematicians such as Chen Jingrun, Lu Qikeng, Yang Le, etc. In order to cultivate the younger generation, he has compiled some extracurricular reading materials for middle school students.
