Liu Hui (born around 250 AD), wei ren in the late Three Kingdoms period, was an outstanding mathematician in ancient China and one of the founders of China's classical mathematical theory. History books rarely record his birth, death and life story. According to limited historical data, he was from Zouping, Shandong Province in Wei and Jin Dynasties. Never been an official. Liu Hui's mathematical works are rarely handed down to later generations, and all of them have been copied over and over again. His main works are: Nine Chapters of Arithmetic Notes (volume 10); The weight difference (1) was renamed as island calculation in the Tang Dynasty. "Nine Chapters Heavy Difference Map" L volume, but unfortunately the last two were lost in the Song Dynasty.
Yang Hui was an outstanding mathematician and mathematics educator in the Southern Song Dynasty. /kloc-in the middle of the 0/3rd century, he was active in Suzhou and Hangzhou with many works. Yang Hui, one of the four great mathematicians in Song and Yuan Dynasties, was the first mathematician in the world to draw a wealth of vertical and horizontal maps and discuss their composition rules. Yang Hui summed up and developed the agile algorithm for calculating multiplication and division, and created the name of "vertical and horizontal graph". Following Shen Kuo's "gap product", the study of higher-order arithmetic progression initiated "accumulation product". The 246 problems in Nine Chapters of Arithmetic are divided into nine categories again according to the order of solving methods from shallow to deep.
Mei Wending, a native of Xuancheng, Shexian County, Anhui Province, was a self-taught mathematician in the late Ming and early Qing Dynasties. Born in March 16 1633 (the seventh day of February in the sixth year of Chongzhen in Ming Dynasty) and died in 172 1 year (the sixtieth year of Kangxi). He lived in an era when western mathematics was first introduced to China, and mathematicians in Qing Dynasty studied and expounded the introduced mathematical knowledge. His mathematical research work had a great influence on the development of mathematics in China's later generations. When I was a teenager, I followed my father Mei Shangchang and my teacher Luo to observe the astronomical phenomena. At the age of 29, he began to learn from Xuancheng Taoist priests about Taigong bronze officials and dating method. From then on, he decided to teach himself astronomical calendar. Over the past decades, I have accumulated more than 60 years of energy and written more than 70 kinds of books (including more than 20 kinds of mathematics books and more than 40 kinds of astronomical documents). In mathematics, he wrote many important works, such as Equation Theory, General Theory of Chinese and Western Arithmetic, Pythagoras' Example, General Solution of Geometry, Outline of Plane Triangle and Outline of Isolated Triangle, covering arithmetic, algebra, geometry, plane triangle and spherical triangle in mathematics.
Germain (1776~ 183 1) is a famous French mathematician. When she was born, the social order in France was in chaos. For the sake of safety, germain, a teenager, was kept at home by her parents to study all day, and her father gave her good living habits and self-study ability. These laid a good foundation for germain's achievements in the field of mathematics.
/kloc-At the age of 0/8, germain founded a world-famous university-University of Science and Technology. Many mathematicians at that time gathered here, such as Laplace and Lagrange. Germain was fascinated by this university. However, she encountered difficulties in registering at school. It turns out that although the French bourgeois revolution has broken out for five years, the discrimination against women in France has not changed, and the comprehensive university of science and technology only accepts boys.
Can't women work in mathematics? Secularity did not make this strong girl shrink back, but strengthened her determination to take the road of self-study, and she vowed to change the secular prejudice against women. She compared the mathematical works of Euler, Gauss and Lagrange, and found that Lagrange's works are easy to understand and most suitable for self-study. Lagrange's works brought endless pleasure to germain, and she had the impulse to write a paper. She wants to write these experiences into a math paper.
The paper has been written. Who should I give it to? Send it to Professor Lagrange? Can a girl's article attract Professor Lagrange's attention? Maybe the professor threw the trash can without looking! After thinking for a long time, she decided to send these documents in the name of Mr. Brown.
Lagrange read Mr. Brown's letters and articles more than once and was full of praise. This talented young man who has never met before aroused the professor's great interest, and his wife suggested that he meet this Mr. Brown. Lagrange personally visited the house. After meeting him, he found that Mr. Brown was actually a shy and beautiful girl. Lagrange was very surprised by germain's self-study ability. He thought that her understanding of mathematics far exceeded that of male students in comprehensive university of science and technology. He offered to be the coach of Germanic.
Under the guidance of Lagrange, germain made faster progress and later became the most famous female mathematician in French history.
Gilad Girard Desargues is a self-taught mathematician. He was an officer when he was young. Later, he studied engineering technology and became an engineer and architect. He disapproves of theory for the sake of theory, and is determined to prove the conic theorem with new methods. 1639, he published his main work "the first draft about the intersection result of conic curve and plane", in which he introduced many new geometric concepts. His friends Descartes, Pascal and Fermat all spoke highly of his works, and Fermat even thought that he was the real founder of conic theory.
