Who knows who invented the four great inventions? 15

Papermaking was invented by Cai Lun, movable type printing was invented by Bi Sheng, and the compass and gunpowder were invented by unknown ancient working people.

The Four Great Inventions are a point of view on the history of Chinese science and technology, referring to the four inventions that had a great impact on the world in ancient China, and are important creations of the ancient Han working people, generally referring to papermaking, compass, gunpowder and printing.

This theory was first put forward by the British sinologist Joseph Needham and later inherited by many Chinese historians, and it is generally believed that these four inventions have played a great 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.

Compass: It is said that when the Emperor was fighting Chiyou, the Yellow Emperor used the "Guide Car" to deal with the fog of Chiyou. But it's just a legend. But it is enough to prove that China was the first country to make a compass.

I think it goes without saying that everyone knows about the invention of printing and papermaking.

Gunpowder originated during the Warring States period. At that time, there were some alchemy (gold) warlocks who wanted to be immortal and turn stones into gold in order to make **, and how to get ** had to be explained with chemical knowledge. The discovery of red powder was around the time of the Song Dynasty.

No one knows that the paper was found in the tomb of the Western Han Dynasty.

The earliest print is the 868 engraved Diamond Sutra, but no one knows who invented it.

Gunpowder was invented by Fang Shi during the Tang Dynasty, but it is not clear who invented it.

The compass can be traced back to Sinan during the Warring States period, but it is not known who invented it, and by the time of the Song Dynasty, there was a compass.

In general, papermaking was improved by the eunuch Cai Lun.

Gunpowder and compass were made by Taoist priests who did not know how.

Bi Sheng's movable type printing is true.

It is added that papermaking was further modified by Cai Lun in 105 A.D. rather than his first creation, and the real inventor is not recorded in the history books, and it is remembered that paper appeared before the Han Dynasty

Pigs know, of course, it's the Chinese pull!

The four major inventions are papermaking, compass, gunpowder and movable type printing, among which the inventor of papermaking is Cai Lun, the inventor of the compass is said to be Xuanyuan Yellow Emperor, gunpowder was invented by ancient Chinese alchemists in the process of alchemy, and the inventor of movable type printing is Bi Sheng.

The theory of the four great inventions originated from the British sinologist Joseph Needham.

The four inventions have played a huge role in promoting the political, economic and cultural development of ancient China, and have been transmitted to the West through various channels, exerting a huge influence on the history of the development of world civilization.

Historical significance

The Four Great Inventions are a series of glorious footprints left by ancient Chinese ancestors for the world, and a symbol of great contributions to the progress of human civilization.

The invention of papermaking: it provided economic and convenient writing materials for human beings, and set off a revolution in human writing carriers; The invention of block printing: greatly contributed to the spread of culture.

The invention of the compass: it provided the conditions for the navigation activities of European navigators, and the use of gunpowder ** changed the way of warfare, helped the European bourgeoisie destroy the feudal fortresses, and accelerated the course of European history.

The invention of the compass is the result of the understanding of the magnetism of objects by the ancient working people of our country in the long-term practice. As a result of productive labor, people came into contact with magnetite and began to understand the properties of magnetism.

Gunpowder was invented by ancient Chinese alchemists in the Sui and Tang dynasties, more than 1,000 years ago. The study of gunpowder began with the alchemy of ancient Taoism, Taoist priests in order to seek immortality and refine elixir, although poisoned many Taoist priests and emperors, but its experimental methods still have merit, and finally led to the invention of gunpowder.

Shen Kuo's 1088 book Mengxi Bi Tan attributed the invention to the unknown craftsman Bi Sheng (990-1051). With the use of sintered clay characters, Shen Kuo described Bi Sheng's production of glyphs, picking up the characters and arranging them, printing them, and disassembling them after printing for later use.

People know Cai Lun papermaking, in fact, before Cai Lun in the Eastern Han Dynasty made large-scale paper, the Chinese had already invented papermaking, as evidenced by many ancient pieces of paper from the Western Han Dynasty unearthed throughout China in the 20th century. This is not to deny Cai Lun's papermaking skills, but to say that Cai Lun's papermaking technology is not a sudden invention, it has a process of technology accumulation.

None of these technologies were invented by one person, but were the result of the practice of working people.

China's four major inventions are papermaking, compass, gunpowder, printing, and Cai Lun is the inventor of papermaking, the ancestor of the compass appeared about the Warring States Period, the specific person is unknown, gunpowder was invented by ancient Chinese alchemists in the process of alchemy, and Bi Sheng became the ancestor of printing.

The development process of the four major inventions

1. Compass

According to legend, it was used to identify the direction of the march when the Yellow Emperor fought Chiyou. The guide car is in fact a mechanical device, and the hands of the immortals point in the same direction when the guide car is moving.

The principle of making a compass car is different from the compass's use of magnetic force to indicate direction. During the Warring States period, the instrument Sinan who really used the magnetic force of a magnet to indicate the direction appeared.

During the Song Dynasty, the technology of making the compass was greatly improved, which indirectly led to the prosperity of China's navigation industry, and the Arabs and Persians who interacted with China learned to use the compass and spread it to Europe.

2. Gunpowder

Gunpowder was invented by alchemists in the process of alchemy. The dragon cannon is like a bazooka, with two small rockets at the head and tail of the dragon cannon, and when the small rockets are ignited, the bazooka will rise, and then ignite the other rockets inside the bazooka and shoot at the enemy, usually in water battles.

In the Tang Dynasty, gunpowder was already used in warfare, and in the Song Dynasty, it already had the lethality of the iron can type**. Chinese gunpowder was transmitted to Arabia and then to Europe through the Mongol conquests.

3. Printing

Before the printing technology, the books were copied by hand one by one, and later there were rubbing, engraving and other printing methods, but it was still very time-consuming and laborious, until the Song Dynasty, Bi Sheng invented movable type printing, which greatly improved the printing technology.

Use cement to make a square with the same specification, and engrave text on one end, which is called a movable type printing pad. When printing, the movable type printing pad is arranged according to the content of the article, fixed on the chassis coated with adhesive to become a movable type plate, and then the plate is inked, and then the text can be printed by laminating it with paper.

4. Papermaking

The earliest Chinese writing appeared in the oracle bone inscriptions of the Yin Shang dynasty, and then there were Zhong Ding inscriptions (also known as Jin inscriptions) cast on the bells, and in the Spring and Autumn Period and the Warring States Period, people began to engrave the characters on wooden tablets and use ropes to run through the books.

In the Qin and Han dynasties, writing was written on silk cloth with a pen, and it was not until the Eastern Han Dynasty that the eunuch Cai Lun improved the method of making paper, and people began to use paper as a writing tool in large quantities. Papermaking is a major event in the history of human civilization, and it took more than a thousand years for this advanced technology to reach Europe.

The inventor of papermaking is Cai Lun, the inventor of the compass is said to be Xuanyuan Yellow Emperor, gunpowder was invented by ancient Chinese alchemists in the process of alchemy, and the inventor of movable type printing is Bi Sheng.

The four major inventions refer to the four inventions of papermaking, compass, gunpowder and printing that had a great impact on the world in ancient China.

The four great inventions have played a great 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.

The significance of the four great inventions

Although many important achievements of Chinese civilization are named after the "Four Greats" and "Five Greats", such as the Four Great Beauties, the Four Classical Classics, and the Four Books and Five Classics, the concept of the Four Great Inventions was adopted by Western scholars and later accepted by the Chinese.

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

In 1620, the English philosopher Bacon also mentioned in his book "New Tools" that the three inventions of printing, gunpowder, and the compass had changed all the faces and situations of things around the world.

The four major inventions in China are papermaking, the compass, gunpowder and printing.

Papermaking was improved by Cai Lun of the Eastern Han Dynasty.

The compass is made by Luan Da (rudimentary), the ancestor of the compass appeared around the Warring States period, and the specific person is unknown.

Gunpowder was invented by Sun Simiao.

Movable type printing was invented by Bi Sheng.

The Four Great Inventions are a point of view on the history of Chinese science and technology, which refers to the four inventions that had a great impact on the world in ancient China, and are important creations of the working people in ancient China.

China's four great inventions were successively introduced to the West before the emergence of modern European civilization, and had a certain impact on the development of Western science and technology. The adoption of gunpowder and firearms destroyed the ideological yoke of medieval Catholicism in Europe. The compass reached the hands of European navigators, making it possible for them to discover America and make it possible to sail around the world, laying the foundations for the development of world and workshop crafts for the West.

Bi Sheng's invention of movable type printing, Cai Lun's papermaking method, gunpowder was invented by ancient Chinese alchemists in the process of alchemy, and the specific inventor has not been verified, but it is recognized that the invention and spread of gunpowder is inextricably linked with Sun Simiao, the "king of medicine" in the Tang Dynasty, so it is also believed that Sun Simiao is the inventor of gunpowder. Compass, according to legend is 27 BC
