China s great scientists, China s ten greatest scientists

Who said that Qian Xuesen is not a scientist, I think Qian Xuesen is better than Yang Zhenning in terms of personality charm, science has no borders, but scientists have national borders, at that time the country was in difficulty, Yang did not return to China, and now that the country is rich and strong, he ran back to China, how can I evaluate a person as a scientist? Is only the person who gets the Nobel Prize a scientist?

The ten greatest scientists in China are Qian Xuesen. Li Siguang, Yuan Longping, Zhu Kezhen, Deng Jiaxian, Qian Weichang, Hou Debang, Qian Sanqiang, Zhou Peiyuan, Mao Yisheng.

Qian Xuesen is a famous physicist in China and a world-famous rocket expert. A native of Hangzhou, Zhejiang, born in Shanghai, with a doctorate, he is known as the "father of Chinese missiles".

1, Yuan Longping.

Yuan Longping is a pioneer and leader in the field of hybrid rice research, committed to the research, application and promotion of hybrid rice technology, invented the "three-line method" indica hybrid rice, successfully developed the "two-line method" hybrid rice, and Liang Xiao created the super hybrid rice technology system. And put forward and implemented the "Three Yields and Four Bumper Yield Project", using the technical achievements of super hybrid rice, published 6 monographs in Chinese and English, and published more than 60 articles.

2. Wang Xuan. Wang Xuan is an expert in computer text information processing, the founder of computer Chinese character laser phototypesetting technology, the pioneer of the contemporary Chinese printing industry revolution, known as the "father of Chinese character laser phototypesetting system", and known as "a scientist with market vision".

3, Jack Ma. Born on September 10, 1964 in Hangzhou, Zhejiang Province, his ancestral home is Gulai Town, Shengzhou City, Zhejiang Province, the main founder of Alibaba Group, and currently serves as a director of SoftBank Japan, chairman of The Nature Conservancy's China Council and a member of the global board of directors, a director of Huayi Brothers, a director of the Life Sciences Breakthrough Award**, and a co-chair of the United Nations High-level Panel on Digital Cooperation.

4, Wu Wenjun.

Wu Wenjun's research work involves many fields of mathematics, and his main achievements are in the fields of topology and mathematical mechanization. He did foundational work on topology; His research on demonstrative classes and demonstrative embeddings has been called "Wu formula", "Wu demonstrative class", and "Wu demonstrative embedding class" by the international mathematical community, and is still widely cited by international peers.

5, Ma Huateng.

He was born on October 29, 1971 in Bashogang, Dongfang County, Guangdong Province (now Dongfang City, Hainan Province). He received a bachelor's degree in science from Shenzhen University in 1993. One of the main founders of Tencent.

China has 5,000 years of historical accumulation and cultural heritage, and there have been well-known scientists in all dynasties, but the current standard of scientists is mainly based on Western standards, so well-known scientists in modern times are more well-known to the world, and simply talk about China's well-known scientists. Cai Lun, he summed up the experience of people in the past, innovated the papermaking process, and created the "Cai Hou Paper", which was later ordered to be promoted by Emperor Han He, and Cai Lun's improved papermaking technology was listed as the "Four Great Inventions" in ancient China. Cai Lun's popularity is extremely high, not only widely known in China, but also in the world, the popularity is also very high, after all, the invention of paper has changed people's lives and promoted the development of civilization, so the famous American scholar Mike Hart ranked Cai Lun seventh in the "List of 100 Celebrities Who Influenced the Process of Human History".

However, Cai Lun is not the inventor of papermaking, he is only the inventor of "Cai Hou Paper", and his invention is low cost and easy to promote. In fact, in 1986, a piece of paper was unearthed in the tomb of the Han Dynasty in Gansu, and this paper is smooth and smooth, painted with mountains, rivers, roads, etc., and this paper is the earliest known paper in the world, compared with the "Caihou paper" in the Western Han Dynasty, it is many years earlier. There are many well-known Chinese scientists in modern times, and guess such as Zhan Tianyou in the early days, the Qing Dynasty went abroad to study, was admitted to the Department of Civil Engineering of Yale University, majored in railway engineering, and was responsible for the construction of the Beijing-Zhang Railway, which was the first railway chief engineer in China, and was called "the father of Chinese railways" and "the father of modern Chinese engineering" by later generations; Another example is Qian Xuesen in the middle period, graduated from Jiaotong University, and later went to the United States to study, known as the "father of China's aerospace" and "the father of China's missiles"; Another example is the recent Yuan Longping, who is the winner of the first National Highest Science and Technology Award and is known as the "father of hybrid rice"; Tu Youyou, China's first Nobel Prize winner in medicine, artemisinin inventor, and winner of the Medal of the Republic.

There are too many well-known scientists in China, and in any historical period, under any difficult conditions, a large number of scientists will emerge, after all, the diligence and wisdom of the Chinese are recognized by the world!

Cai Lun By the beginning of the 7th century A.D. (late Sui and early Tang Dynasty), it began to spread eastward to Korea and Japan; In the 8th century, it was introduced to Samarkand, and then to Baghdad. The invention of papermaking is not only a great revolution in the materials used to make books, but also has epoch-making significance in the history of human civilization.

Zu Chongzhi Zu Chongzhi (429 500).

He was a famous mathematician and scientist in the Song and Qi dynasties of the Southern Dynasties.

The words are far away. Fan Yangxuan (now Laishui, Hebei).

He has made significant achievements in mathematics, astronomy, calendar, and mechanical engineering.

On the basis of his predecessors, he deduced that the value of pi is between and , and he was the first mathematician in the world to accurately calculate the value of pi to the seventh decimal place, and proposed the approximate rate of 22 7 and the dense rate of 355 113;And the German Otto did not reach this level until 1573, more than a thousand years earlier than in Europe.

Therefore, people call the density rate also known as the "ancestral rate".

The "Da Ming Calendar" compiled by him first took into account the calculation of precession, stipulating that a year is a day, and the data on the cycle of the sun and moon is more accurate than other calendars at that time.

Great achievements have also been made in mechanical engineering.

The "Fixation Technique" and the "Nine Chapters of the Commentary on the Meaning of the Technique" have been lost, and there are also "Yi Laozhuang Yi Interpretation", "Commentary on the Analects of Filial Piety", and there are 51 volumes of "Zu Chong's Collection", and his book "Shu Wei Ji" (someone Yun is written by Liang Renfang of the Southern Dynasty, but Tang Wei Zheng and others edited the "Book of Sui. Zhi", Liu Xixiu of the Later Jin Dynasty "Old Tang Book. The Chronicles of the Classics and the "New Tang Dynasty Calligraphy and Art Chronicles" edited by Song Ouyang Xiu and Song Qi of the Qing Dynasty are all entitled by Zu Chongzhi), which is a masterpiece of Zhiwei books.
