Who invented China s five major inventions? What was invented?

In ancient China, there were only four major inventions: the compass.

Papermaking, gunpowder and printing.

Inventor: Movable Type Printing: Bi Sheng.

Compass: Not documented.

Gunpowder: Ancient alchemist.

Papermaking: Cai Lun.

Introduction to the Four Great Inventions:

1.The Four Great Inventions refer to the four inventions of ancient China that had a great impact on the world. Namely, papermaking, compass, gunpowder, movable type printing. This was first coined by the British sinologist Joseph Needham.

Presented and later by many Chinese historians.

It is generally believed that these four inventions have played a huge role in promoting the political, economic and cultural development of ancient China, and these inventions have been transmitted to the West through various channels, and have also had a great impact on the history of the development of world civilization.

2.Despite the Chinese civilization.

There are many important achievements named after the "Four Greats" and "Five Greats", such as the Four Great Beauties, the Four Classical **, and the Four Books and Five Classics.

However, the concept of the four great inventions was adopted by Western scholars and later accepted by the Chinese.

3.As early as 1550, the Italian mathematician Jerome Cardin was the first to point out that China's "three major inventions" had an impact on the world: Sinan (the compass), printing and gunpowder. And considered them "an invention that has no rival in the whole of antiquity." ”

In the year, the British philosopher Bacon also wrote in "New Tools".

"The three inventions of printing, gunpowder, and the compass have changed the whole face and situation of things around the world," the book says. ”

5.Then, in 1861-1863, Marx.

And Engels pushed the significance of these inventions to a high point, and Marx wrote in "Machinery, Natural Forces and the Application of Science": "Gunpowder, the compass, the printing press - this is a foretaste of the bourgeoisie."

The three major inventions that society has arrived. Gunpowder blew the knightly class to pieces, the compass opened the world market and established colonies, and the printing press became an instrument of Protestantism and, in general, a means of scientific revival, the most powerful lever for creating the necessary prerequisites for spiritual development. ”

6.Engels wrote in The German Peasants' War

"A series of inventions have their own greater or lesser significance, among which gunpowder has a glorious historical significance. It has now been established beyond any doubt that gunpowder was transmitted from China to the Arabs through India, and from the Arabs to Europe through Spain, along with gunpowder**.

7.British sinologist Maddox pointed out: "The inventive genius of the Chinese has long been manifested in many aspects. The three major inventions of the Chinese (nautical compass (Sinan), printing, gunpowder) provided an extraordinary impetus for the development of European civilization. ”

Movable type printing: Bi Sheng.

Compass: Shen Kuo.

Gunpowder: Ancient alchemist.

Papermaking: Cai Lun.

Papermaking, movable type printing, gunpowder, compass.

Zhuge Liang invented Kong Ming lantern, and Du Shi invented water drainage.

Ask what are the inventions of zoology.

Bats emit a kind of ultrasound wave that comes back when it encounters an object, but humans can't hear it. Radar was invented based on this property of bats. Radar is used in a variety of places, such as airplanes, aviation, etc.

2. Fireflies and artificial cold light.

Based on the study of fireflies, fluorescent lamps were created, which changed the source of human lighting a lot. Scientists first isolated pure luciferin from the luminous apparatus of fireflies, and later isolated luciferase, and then chemically synthesized fluorescein. A biological light source composed of a mixture of luciferin, luciferase, ATP (adenosine triphosphate) and water, which can be used as a flash lamp in mines filled with ** gas.

It has been possible to obtain cold light similar to biological light by mixing certain chemicals as a safety lighting.

3. Electric fish and volt battery.

At the beginning of the 19th century, the Italian physicist Volt designed the world's earliest volt battery based on the electric fish power generation organ. Because this battery is designed based on the natural generator of electric fish, it is called "artificial electric organ". The study of electric fish also gives people such enlightenment:

If it is possible to successfully imitate the power generation organ of an electric fish, then the power of ships and submarines, etc.

4. Dragonflies and helicopters.

The dragonfly vibrates through its wings to create locally unstable air currents that are different from the surrounding atmosphere, and uses the vortices created by the air currents to make itself rise. The Dragonfly can soar with very little thrust and can fly not only forward, but also backward and left and right, and can fly forward at speeds of up to 72 km/h. In addition, the dragonfly's flight behavior is simple, relying on only two pairs of wings to flap constantly.

Scientists have successfully developed a helicopter based on this structural basis.

5. Flies and vibrating gyroscopes.

Entomologists have found that the hindwings of flies degenerate into a pair of balancing rods. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the direction of movement of the wings and is a navigator that keeps the fly's body balanced.

Can the question be specific to the personal information of the inventor?

Mainly inventions of Chinese scientists.

Ask who invented the butterfly satellite temperature control system.

Shen Kuo invented the compass; Cai Lun invented papermaking; Huasheng invented movable type printing, and Zhang Heng invented the ground motion instrument; Zhuge Liang invented the Kong Ming lantern; Du Shi invented the water drain.

Chinese Inventions:

1. Paper Cai Lun, a eunuch of the Eastern Han Dynasty. Using tree bark, broken fish nets, eggplant, rags, hemp and other raw materials, it is made of plant fiber paper suitable for writing. He was named the Marquis of Longting by Emperor He, and was called Cai Hou Paper.

2. Movable type printing Bi Sheng, Northern Song Dynasty Hubei Yingshan cloth clothes. According to Shen Kuo's "Dream Creek Pen Talk", it is engraved on the clay sheet, one word is printed, and it becomes a movable type after being burned hard. It can be printed on ink and paper, and the movable type can be removed after baking, and it can be reused.

3. Loom Huang Daopo, a native of Shanghai at the end of the Southern Song Dynasty, was born as a child daughter-in-law. He learned textile technology from Li Min in Yaxian County, Hainan, and returned to his hometown to reform cotton spinning tools, including seeding and churning, cotton vertebral arches, and three-spindle pedal spinning wheels.

4. Hydraulic blower Du Shi, Nanyang Taishou of the Eastern Han Dynasty. The water drain is powered by scattered water, and the leather blower bag is continuously opened and closed through a rolling machine, and the air is sent into the iron-smelting furnace, which is called "Du Shi water drain", the world's earliest Chongmin tung hydraulic blower.

5, match Northern Qi palace maid. According to Tao Gu's "Qing Yilu", in 577, the Northern Qi Dynasty was attacked on both sides, lacking fire to cook and keep warm, and in despair, a group of poor palace maids magically invented matches and made them of sulfur.
