Archimedes has many stories, the most important of which is the story of discovering Archimedes' principle in the bath. The king made a golden crown. He suspected that the craftsman had stolen some gold with silver, so he asked Archimedes to identify whether it was made of pure gold and not to damage the crown. Archimedes thought hard about the crown all day. One day, Archimedes went to the bathroom to take a bath. He went into the bath tub. When he immersed himself in the bath bucket, some water overflowed from the side of the bucket. Archimedes saw this phenomenon and crackled in his mind. "I found it!"
Archimedes put an equal weight gold nugget and a silver nugget into a container filled with water, and found that the silver nugget discharged much more water. So Archimedes took a gold nugget with the same weight as the crown and put it in a container filled with water to measure the displacement; Then put the crown in a container filled with water to see if the amount of water discharged is the same, and the problem will be solved. With further research, Archimedes principle, the most important cornerstone of fluid mechanics, was born.

Mathematician Chen Jingrun lived a very simple life when he was studying in university. He always wears black student clothes. Because of his poor family, he often eats two meals a day in order to spend the money saved on books. He said, "You can skip meals and books." He usually doesn't watch movies, just chats with people and concentrates on his studies. At that time, the dormitory had a system of turning off the lights on time. In order not to affect others' rest, he buried his head under the bed and read with a flashlight.

Euler was born in April 1707 in Basel, Switzerland and died in September 1783 in St. Petersburg, Russia. He was born into a family of priests. /kloc-he got his bachelor's degree in university of basel at the age of 0/5 and his master's degree the following year. 1727, Euler went to Russia at the invitation of St. Petersburg Academy of Sciences. 173 1 year, he succeeded daniel bernoulli as a professor of physics. He devoted himself to research with great energy. During his 14 years in Russia, he did a lot of outstanding work in the fields of analysis, number theory and mechanics. 174 1 invited by frederick the great of Prussia to work in Berlin Academy of Sciences for 25 years. During his stay in Berlin, his research contents were more extensive, involving planetary motion, rigid body motion, thermodynamics, ballistics and demography, which promoted each other with his mathematical research. During this period, Euler's research in differential equations, differential geometry of surfaces and other mathematical fields was groundbreaking. He returned to St. Petersburg on 1766. Euler is one of the most outstanding figures in the field of mathematics in the18th century. He not only made great contributions to mathematics, but also applied mathematics to almost the whole field of physics. He is also a prolific writer. He wrote a large number of textbooks on mechanics, analysis, geometry and variational methods. Introduction to Differential Analysis, Principles of Differential Calculus and Principles of Integral Calculus have all become classic works in the field of mathematics. Apart from textbooks, his complete works have 74 volumes.

Yang Hui, an outstanding mathematician in the Southern Song Dynasty, played a very important role in the history and education of ancient mathematics in China. Yang Hui left a large number of works in his life, including five kinds of 2 1 volumes, which greatly enriched the treasure house of ancient mathematics in China and made outstanding contributions to the development of mathematical science. 5.

Xiong Qinglai (1893.09.11~1969.02.03) is a native of Xizi Village, Maitreya City, Honghe, Yunnan Province. Xiong Qinglai loves education and has made outstanding contributions to the cultivation of scientific talents in China. Xiong Qinglai has developed a good habit of being diligent and eager to learn since he was a child. His extraordinary memory and natural language acceptance often amaze Chinese and foreign teachers who have educated him. He devoted himself to academic research and writing, and compiled 10 and other university textbooks, which were written in Chinese for the first time at that time. He founded the first modern mathematics research institution in China-Tsinghua University Mathematics Research Department, the mathematics departments of Southeast University and Tsinghua University University, and the China Mathematics Journal. He has always been rigorous in his studies, and his math papers are often revised more than three or five times. During his tenure as a professor, he always corrected students' homework very carefully. He read carefully and corrected the mistakes in his homework with a red pen. For good homework, write a word "good" with big strokes to express satisfaction. He often forgets to eat and sleep and works regardless of illness. According to Xiong Qinglai's wife, in the first year of Southeast University, he vomited blood due to fatigue and suffered from hemorrhoids. Xiong Qinglai stubbornly lay in bed and insisted on writing teachings. Xiong Qinglai has made great achievements in the field of "Functionalism". 1932 He represented China for the first time at the International Congress of Mathematicians held in Zurich, Switzerland. 1934 published the paper "On Integer Functions and Meromorphic Functions of Infinite Order", and obtained the French national doctorate, becoming the first China person to obtain this degree. In this paper, the "infinite order function" defined by Xiong Qinglai, known internationally as "Xiong's infinite number", has been recorded in the history of world mathematics and established his position in the international mathematics field.
