1936, on the recommendation of Professor Xiong Qinglai, Hua went to Cambridge University in England to study. Hardy, a famous mathematician in the 20th century, has long heard that China is brilliant. He said, "You can get a doctorate in two years." But Hua said, "I don't want to get a doctorate. I just want to be a visitor." "I'm here to study in Cambridge, not to ask questions. He also published 18 papers on the Waring problem, tally problem, and CheGoldbach problem, and obtained the famous Fahrenheit theorem, which showed the outstanding wisdom and ability of China mathematicians to the whole world.
1946, Hua was invited to give lectures in the United States and was hired as a tenured professor by the University of Illinois. His family also settled in the United States, with a house and a car, and their life was very comfortable. At that time, many people thought that Hua would never come back.
The birth of the new China touched China's love for the motherland. 1958+0950, he resolutely gave up his rich life in America and returned to his motherland. He also wrote an open letter to China students studying in the United States, urging them to return to China to participate in socialist construction. In his letter, he revealed a childlike heart that loves China: "Friends! Liangyuan is a good place, but it is not the hometown of long residence. Go back to Xi ... For the country and the nation, we should go back ... "Although mathematics has no national boundaries, mathematicians have their own motherland.
Hua returned from overseas and was warmly welcomed by the party and people. He returned to Tsinghua campus, was appointed as the head of the Department of Mathematics, and was soon appointed as the director of the Institute of Mathematics of China Academy of Sciences. From then on, he began the real golden age of his mathematical research. He has not only made remarkable achievements that have attracted worldwide attention, but also enthusiastically cared for and trained a large number of mathematical talents. In order to win the crown jewel of mathematics, he devoted a lot of efforts to the research, experiment and popularization of applied mathematics.
According to incomplete statistics, Hua * * * has published a total of important mathematical papers 152, 9 mathematical works, and1/mathematical popular science works for decades. He was also elected as a foreign academician of the Academy of Sciences and an academician of third world scientists.
From graduating from junior high school to becoming a people's mathematician, Hua has gone through a tortuous and brilliant life path and won great honor for his motherland.
