Story: In order to get the accurate value of pi, Zu Chongzhi needs to calculate the decimal of nine significant figures, including more than ten steps such as addition, subtraction, multiplication, division and square root operation. Each step has to be repeated for more than ten times, and the square root operation has been carried out for 50 times. Finally, the calculated figure reaches 16 or 17 decimal places.
2. Liu Hui: Han nationality, a native of Zouping City, Binzhou, Shandong Province, was a great mathematician in Wei and Jin Dynasties and one of the founders of China's classical mathematical theory. He is a very great mathematician in the history of Chinese mathematics. His representative works "Nine Arithmetic Notes" and "Arithmetic on the Island" are China's most precious mathematical heritage.
Story: He cut a circle by connecting a regular hexagon from a circle with a diameter of 2 feet, and got a regular 12 polygon and a regular 24 polygon in turn. The smaller the incision, the smaller the difference between the regular polygon area and the circular area. He calculated the area of 3072 polygons and verified this value. The scientific method of calculating pi put forward by Liu Hui has established China's leading position in the world for more than 1000 years.
3. Su, a native of Pingyang, Wenzhou, Zhejiang, and Quanzhou, Fujian, is an academician of China Academy of Sciences, a famous mathematician and educator in China, and the founder of China School of Differential Geometry. He is known as "the brilliant star of mathematics in the East", "the first geometer in the East" and "the king of mathematics".
Story: Su and Chen saw the necessity of the connection between various branches of mathematics, implemented the principle of teaching students in accordance with their aptitude, and decided to let Gu Chaohao and Zhang Mingyong have two discussion classes on "Differential Geometry" and "Function Theory" at the same time, which was also a pioneering work at that time.
4. Hua: China is the founder and pioneer in the research of analytic number theory, matrix geometry, canonical group, automorphic function theory and multivariate complex function theory, and is listed as one of the 88 great mathematicians by the Chicago Museum of Science and Technology. The international achievements in mathematical research include Fahrenheit theorem, Fahrenheit inequality and Hua Wang method.
Story: During his teaching in Tsinghua, Wu stayed at home to take care of his elderly and sick father-in-law. In the later days, she not only did housework, but also helped him copy papers and letters and receive guests. For decades, Wu has been playing an important role in China's life and career.
5. Chen Jingrun: Male, Han nationality, independent, from Fuzhou, Fujian, a contemporary mathematician. 1973 published a detailed proof of (1+2), which is recognized as a great contribution to the study of Goldbach's conjecture.
Story: He has superhuman diligence and tenacious perseverance. He has devoted himself tirelessly to mathematics research for many years, forgetting to eat and sleep, and working 12 hours or more every day. When he was suffering from illness, he never stopped his pursuit and made great contributions to the development of mathematics.
