The life deeds of ten Chinese and foreign mathematicians, urgent!

Chinese mathematicians are:

1. Hua Luogeng (November 12, 1910 - June 12, 1985), former vice chairman of the National Committee of the Chinese People's Political Consultative Conference. Born in Jintan District, Changzhou, Jiangsu, native of Danyang, Jiangsu, mathematician, academician of the Chinese Academy of Sciences, foreign academician of the National Academy of Sciences of the United States, academician of the Third World Academy of Sciences, academician of the Bavarian Academy of Sciences of the Federal Republic of Germany, researcher and former director of the Institute of Mathematics of the Chinese Academy of Sciences.

2, Xu Guangqi (1562-1633), the word first, the name Xuanhu, Zhen Wending, Shanghainese, Wanli Jinshi, official to Chongzhen Dynasty Rite Department Shangshu and Wenyuan Pavilion University Scholar, cabinet assistant. He devoted his life to the study of science and technology, and was an agronomist, astronomer, and mathematician in the Ming Dynasty of China.

3. Liu Hui (c. 225-c. 295), Han nationality, a native of Zouping City, Binzhou, Shandong, was a great mathematician during the Wei and Jin dynasties, and one of the founders of classical Chinese mathematical theory. He has made great contributions to the history of Chinese mathematics, and his masterpieces "Nine Chapters of Arithmetic Notes" and "Island Arithmetic" are the most valuable mathematical heritage in China.

4. Shiing-Shen Chern (October 28, 1911, December 3, 2004), originally from Jiaxing, Zhejiang, was one of the greatest geometricians of the 20th century and was known as the "father of integral differential geometry"; He is a former member of the first Academy of Sciences, a member of the National Academy of Sciences of the United States, and a founding member of the Third World Academy of Sciences.

5. Zu Chongzhi (429 500 years), the name Wenyuan, was born in Jiankang County, Danyang County (now Nanjing, Jiangsu), and was born in Fanyang County, Laishui County, Hebei Province, and was an outstanding mathematician and astronomer during the Northern and Southern Dynasties.

The five famous mathematicians in China are: Zu Chongzhi, Zhengpeng Xiong Qinglai, Liu Hui, Zhao Shuang, and Zhu Shijie.

1, Zu Chongzhi.

Founded the "Great Ming Calendar", and calculated pi to seven decimal places.

2, Xiong Qinglai.

He defined an "infinite function", which is known as "Xiong's infinite number" in the world, and Xiong Qinglai has a deep knowledge in the field of "function theory". In 1932, he represented China for the first time at the International Congress of Mathematicians in Zurich, Switzerland.

3, Liu Hui. He was a great mathematician during the Wei and Jin dynasties, and one of the founders of Yu Chun of classical Chinese mathematical theory. His masterpieces, Nine Chapters of Arithmetic Notes and Island Arithmetic, are China's most valuable mathematical heritage.

4, Zhao Shuang. From the end of the Eastern Han Dynasty to the Three Kingdoms period, he was a famous mathematician and astronomer in the history of our country. He studied Zhang Heng's astronomical work "Lingxian" and Liu Hong's "Qianxiang Calendar", and also mentioned "arithmetic".

5, Zhu Shijie.

He was a mathematician and educator of the Yuan Dynasty and devoted his life to mathematics education. He is known as "the greatest mathematician of the medieval world".

A mathematician is a person who has an in-depth understanding of mathematics and applies what he or she has learned to his or her work. Mathematicians focus on numbers, data, sets, structures, spaces, changes.

1. Hua Luogeng, a famous Chinese mathematician, an academician of the Chinese Academy of Sciences, and a foreign academician of the American Academy of Sciences. He is the founder and founder of many aspects of Chinese analytic number theory, curvature groups, matrix geometry, automorphic function theory and multivariate complex variable functions, and is also one of the most influential mathematicians in the world.

2. Thales, an ancient Greek geometer, is the oldest mathematician in history. Born in the prosperous port city of Miletus in Greece, Thales is said to have traveled to Egypt, studied with local shamans, and used the shadow of the sun to measure the height of the pyramids, accurately performing an eclipse, and the mathematical Thales theorem named after him.

3. Zu Chongzhi, the word Wenyuan, an outstanding mathematician and astronomer in the period of the Northern and Southern Dynasties of China, on the basis of the precise method of exploring pi pioneered by Liu Hui, for the first time actuarially calculated "pi" to the seventh decimal place, that is, between and , the "ancestral rate" he proposed made a significant contribution to the study of mathematics.

The distribution law of prime numbers was discovered, and a table of twin prime numbers with distribution laws was compiled.

In the process of waiting for others, you can encyclopedia a hundred.

1.Liu Hui (born around 250 AD) is a historian of Chinese mathematics.

Zu Chongzhi (pinyin zǔ chōng zhī 注音 429 AD 500 AD) was an outstanding mathematician, astronomer, writer, geologist, geographer, and scientist in China. During the Northern and Southern Dynasties, the Qi people, the Han nationality, the word is far away, the ancestral home of Fanyang County (now Laishui County, Hebei), in order to avoid the war, Zu Chongzhi's grandfather Zuchang moved from Hebei to Jiangnan. Zu Chang once served as Liu Song's "Great Craftsman", in charge of civil engineering, and Zu Chongzhi's father was also an official in the court.

Zu Chongzhi, for the first time in the history of mathematics in the world, calculated the value of pi ( ) to six decimal places, that is, to. He proposed a rate of about 22 7 and a density rate of 355 113, which was the earliest in the world, 1100 years earlier than in Europe, so some people advocate calling it "ancestral rate", that is, the ancestor of pi. He compiled the results of his mathematical research into a book called "The Art of Fixation", which was once designated as a mathematics textbook in the Tang Dynasty.

The "Da Ming Calendar" compiled by him introduced "precession" into the calendar for the first time. It is proposed to set 144 leap months in 391 years. The length of a return year is calculated to be days, and the error is only about 50 seconds.

He was not only an outstanding mathematician and astronomer, but also an outstanding mechanical expert. We have recreated a variety of ingenious machines such as the long-lost guide car, the thousand-mile ship, and the water mill.

After years of calculation, he also compiled a new calendar, the "Great Ming Calendar". It was the most advanced calendar in the world at the time.

In addition, he also has research on **.

His works include "Commentary", "Interpretation of the Book of Filial Piety", "Yiyi", "Lao Tzuyi", "Zhuangziyi" and **"Narrative Differences", etc., but they have long been lost.
