Modern Chinese Inventions, Inventors, Time, Significance

Hou Debang's "Hou's alkali method".

The reason for the selection is that it is one of the few and very representative inventions in China's modern history, which has changed the situation between us and can only rely on foreigners to control.

1. Hybrid rice (inventor: Yuan Longping).

Reason: Second Green, Solving Global Hunger.

The Western world calls hybrid rice the "magic rice of the East". His achievements not only solved the problem of feeding the Chinese to a large extent, but also was considered a magic weapon to solve the problem of world hunger in the next century. Internationally, hybrid rice is even regarded as China's fifth greatest invention after the four major inventions, and is known as the "second green".

Yuan Longping is known as the father of hybrid rice in the world, and his contribution to solving the problem of world hunger has benefited hundreds of millions of people.

2. Synthetic bovine insulin.

Reason: The first use of artificial lifeforms.

On September 17, 1965, Chinese scientists synthesized crystalline bovine insulin for the first time in the world by artificial methods. The synthesis of artificial bovine insulin marks a key step in the journey of human beings to understand life and explore the mysteries of life, and its significance and impact are huge. This is the first time in human history that a living protein has been synthesized.

In the past, the world generally believed that life was natural, and most people thought that it was impossible to synthesize life forms, but the Chinese made it possible for the first time.

3. Mathematical mechanization method (inventor: Wu Wenjun).

Reason: To inject vitality into traditional Chinese mathematics.

Later, Wu Wenjun's research interests turned to the history of mathematics in ancient China, and he pioneered the research work known as mathematical mechanization. In the context of the great development of computer technology, he inherited and developed the tradition of ancient Chinese mathematics, and turned to the study of machine proofs of geometric theorems, which completely changed the face of this field, and was called the "Wu method".

Wu Wenjun's method of mathematical mechanization "transforms traditional Chinese mathematical thought and methods into magic". Newton invented calculus, and since then Western mathematics has prevailed, and traditional Chinese mathematics can only "stand aside". But Wu Wenjun was inspired by ancient Chinese mathematics and combined with the principles of contemporary computers to invent the "Wu Method".

Fourth, the theory of continental oil formation (inventor: Li Siguang Scientific Research Collective).

Reason: Take off the hat of China's poor oil.

China has successively built large oil fields in Daqing, Dagang, Shengli and other places, and the role of the theory of continental oil formation has played an important role. Previously, it was believed that large oil fields were only possible in marine formations, and Westerners have confirmed that China is oil-poor because some of China's large Mesozoic basins are mostly terrestrial sediments. Our scientists have come up with the theory that continental facies deposits may also generate large oil fields if the conditions are right.

This breakthrough in basic theory allows us to discover the oil and gas resources under our feet.

5. Chinese Character Laser Phototypesetting (Inventor: Academician Wang Xuan).

Reason: Let printing say goodbye to "lead and fire" and move towards "light and electricity".

The laser phototypesetting technology of Chinese characters is a major breakthrough in basic theory, which has brought a one-time change to the publishing and printing industry and greatly improved the efficiency of the printing and publishing industry. While promoting the spread of Chinese culture, it has also had a profound impact on the printing and publishing industry in Japan, South Korea and other countries.

I don't want to tease you with any gutter oil or poisoned milk powder, but frankly speaking, if it is a revolutionary invention that can promote the progress of mankind, something that can be called a milestone in the international community. The answer is: no.

In modern times, China was closed to the country by the Qing Dynasty, which destroyed the training of scientists, and only a large number of talented people were trained to create a new China for China.

Zhan Tianyou invented the "human" shaped railway, Feng Ru invented China's first airplane, and Academician Yuan Longping cultivated hybrid rice, but the others are really hard to find!!

In the pharmaceutical industry, I.

It is great to think that artemisinin is second only to antibiotics (penicillin) in the number of human beings saved.

A: Let me add a few other industries, the most common, the most influential things for modern humans: USB flash drives, DVD players.

These two things are like karaoke invented by the Japanese, and they have deeply influenced the lives of modern people.

Fengjun [Han Linchun] invented the [Han's 79 rifle].

Heavy bai of modern times

One of the inventions is the "Hou's Du alkali method", in 1917, the patriotic industrialist Zhi Fan Xudong founded Wynn in Tianjin Tangdaogu.

The company is determined to break the monopoly of foreign rights holders and produce soda ash in China. He hired Mr. Hou Debang, who was studying in the United States, as the chief engineer.

In 1920, Mr. Hou Debang resolutely returned to China to take up his post. He devoted himself to the improvement of the alkali production process and equipment, and finally Hou Debang explored the various production technologies of Solvay Method. In August 1924, the Tanggu Soda Plant was officially put into operation.

In 1926, the "Red Triangle" brand soda ash produced in China won the gold medal at the International Exposition in Philadelphia, USA. The products not only sell well in China, but also are exported to Japan and Southeast Asia.

In 1959, geographer Li Siguang and others proposed the theory of "terrestrial oil" to break the DU

The "Chinese poor oil" theory of Western scholars; In 1960, Wang Ganchang, a physicist and others, discovered anti-sigma negative hyperons; In 1964, China's first atomic bomb device was successful; In 1965, biologists synthesized bovine insulin for the first time in the world. In the process, China has formed a number of research institutes with complete disciplines and better equipment, and has cultivated a scientific research team with a relatively high level and strong strength. By 1965, there were more than 1,700 scientific research institutions and 120,000 people engaged in scientific research.

This is the foundation for the continued development of China's scientific and technological undertakings.
