What are the four major inventions? Do you know?

The four great inventions are a 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 ancient Han working people, generally referring to papermaking, compass, gunpowder and cement movable type printing (from China to the West is engraving printing, and later Westerners independently invented their own movable type printing).

About 3,500 years ago, during the Shang Dynasty, China had a script engraved on tortoise shells and animal bones, called oracle bone scripts. In the spring and autumn periods, bamboo and wood chips are used to replace tortoise shells and animal bones, which are called bamboo slips and wooden rafts. The oracle bones and slips are very bulky, and the thinker Hui Shi likes to read during the Warring States Period, and every time he goes out to study, he is followed by five carts full of bamboo slips, so there is an allusion to the five carts of learning and being rich.

In the Western Han Dynasty, among the court nobles, it was written on silk or cotton paper. Silk is fine silk, silk is the general name of silk fabrics, when writing on the silk silk, it is easy to write, not only more than the simple silk, but also can be painted on it, but it is expensive, can only be used by a few palace nobles. 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. The plant fiber paper unearthed in the Western Han Dynasty is the predecessor of Cai Lun papermaking. Cai Lun expanded the scope of papermaking raw materials, rags, fishing nets, bark, hemp and so on can be used to make paper, among which bark paper is his invention.

His papermaking process was more refined, and the art of papermaking came to him, freeing him from the status of a vassal of textiles - which had previously been made from the by-products discarded after weaving, Cai Lun developed papermaking into an independent process. <>

Papermaking Cai Lun, movable type printing Bi Sheng,Compass Ma Junli, Gunpowder The invention of gunpowder is not specifically said who invented it, it was discovered by accident after a long period of experimentation by alchemists in ancient China, and was invented after continuous improvement. China was the first country in the world to invent printing.

The early printing was engraved on the wood board and printed with ink, and the woodblock watermark painting still used this method, collectively referred to as "engraving printing" (also known as "engraving printing") The predecessor of engraving printing was the popular seal printing in BC and the rubbing stele that appeared later. After the advent of production technologies such as papermaking and ink-making, engraving printing technology was gradually invented. The founding time of engraving printing is divided and has not yet been determined.

Many people believe that it was founded in the Eastern Han Dynasty, originated in Luoyang, and prevailed in the Sui and Tang dynasties. <>

Gunpowder was invented by Chinese Han alchemists in the Sui and Tang dynasties, more than 1,000 years ago. The study of gunpowder began with the ancient Taoist alchemy, the ancients refined the elixir in order to seek immortality, the purpose and motivation of alchemy were advanced, but its experimental methods still had merit, and finally led to the invention of gunpowder. Although the alchemists mastered certain chemical methods, their direction was to seek the elixir of immortality, and the invention of gunpowder was a by-product.

Alchemists often use the method of cauterizing sulfur, arsenic and other poisonous gold and stone medicines before using them, and "volt" means to subdue. Losing or reducing toxicity is called "fire". <

What are the four major inventions of China?

The four major inventions are the achievements of wisdom and science and technology in ancient China, including papermaking, compass, gunpowder, and printing.

1. Papermaking.

In 102 A.D., he and Emperor Deng Sui were appointed as queens, and Cai Lun took refuge here. Deng Sui likes to dance and write, while Cai Lun is willing to deign to hold the official rank, in charge of the imperial utensils in the palace and the royal handicraft workshops in the palace. During this period, he summed up the papermaking experience since the Western Han Dynasty, only improved the papermaking process, and refined high-quality paper by using raw materials such as bark, rags (linen), hemp, and fish nets, which was reported to the imperial court in 105 AD, and was praised by Emperor He, and thus promoted.

Papermaking (Caihou paper) was also popularized as a result.

2. Compass.

Originally named Sinan, the compass was discovered during mining between 206 BC and 220 BC, carving a magnet into a spoon shape and placing it on a bronze chassis made of Youfengpei, on which a direction sign was cast. When the spoon stops turning, the direction of Bing's finger is due south.

3. Gunpowder. Invented by an alchemist during the Sui and Tang dynasties, gunpowder is a black or brown granular explosive made from a mechanical mixture of potassium nitrate, charcoal, and sulfur.

In fact, the earliest purpose of the alchemist was to obtain the elixir of life, and gunpowder could not solve the problem of the alchemist, and it was very easy to catch fire. As a result, gunpowder did not have any effect, and later the formula was transferred to the hands of military experts, and it slowly began to be used.

4. Printing.

As one of the four great inventions, it has a long history and is an important part of Chinese culture. It sprouted with the birth of Chinese culture and evolved with the development of Chinese culture.

It has gone through four historical periods: source, ancient, modern and contemporary, with a development process of more than 5,000 years. Seals and stone carvings provided direct inspiration for engraving. The method of using paper to ink on the stele directly pointed out the direction for engraving printing.

Chinese printing has gone through two stages: engraving printing and movable type printing, which has brought a huge gift to the development of mankind, and printing has the characteristics of convenience, flexibility, time-saving and labor-saving.

The four major inventions are: papermaking, compass, gunpowder, and printing, which are the results created by laborers in ancient China in production practice.

The four major inventions are printing was invented by Bi Sheng in the Song Dynasty, the compass was invented by the Yellow Emperor in ancient times, paper was invented by Cai Lun in the Han Dynasty, and gunpowder was invented by an alchemist in the Northern Song Dynasty. A compass is a simple instrument used to determine directions. Formerly known as Sinan.

The main component is a magnetic needle mounted on a shaft that can be rotated freely. Cai Lun's papermaking technology is not a sudden invention, it has a process of technology accumulation. The plant fiber paper unearthed in the Western Han Dynasty is the predecessor of Cai Lun papermaking.

Famous astronomer and inventor in ancient China. During the Eastern Han Dynasty, he held the positions of Langzhong and waiter. In 132 B.C., he invented the geodynamic instrument when he was doing Taishi Ling in the middle of the court.

This great invention has made great contributions to the progress of human civilization and has been sung by later generations. Cai Lun's papermaking technology is listed as one of the "Four Great Inventions" in ancient China, and has made outstanding contributions to the spread of human culture and the progress of world civilization, and has been highly respected by people for thousands of years. It is regarded as the originator of papermaking and the "paper god" by paper workers.

Summary. The four major inventions are 1: papermaking, 2: the compass, 3: gunpowder, and 4: printing.

The four major inventions are 1: papermaking, 2: the compass, 3: gunpowder, and 4: printing.

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 great influence on the history of the development of civilization in the world. 1. Papermaking is one of the four great inventions in China, paper is the crystallization of the long-term experience and wisdom of the working people of the Han nationality, and an outstanding invention in the history of human civilization. 2. Printing began in the Sui Dynasty's carved rough leather simple printing, developed and perfected by Bi Sheng in the era of Song Renzong, produced movable type printing, and was transmitted to Europe by the Mongols, 3, the compass was called Sinan in ancient times, the main component is a magnetic needle mounted on the shaft, the magnetic needle can rotate freely and remain in the tangent direction of the magnetic meridian under the use of the natural geomagnetic field, the north pole of the magnetic needle points to the south pole of geography, and the direction can be identified by using this performance.

4. Gunpowder mainly refers to a black or brown explosive mechanically mixed with potassium nitrate, charcoal and sulfur.

The Four Great Inventions refer to four important inventions in ancient China, including papermaking, the compass, gunpowder, and movable type printing. Papermaking: Papermaking is one of the most important inventions in ancient China, which first appeared in the Eastern Han Dynasty.

In the following few hundred years, China's papermaking technology continued to evolve and gradually became a unique industry. Compass: The compass is a navigational tool in ancient China, which first appeared during the Northern and Southern Dynasties.

It is made of magnets and porcelain, which can indicate directions, and played an important role in ancient navigation and military affairs. Gunpowder: Gunpowder is a substance made from a mixture of saltpeter, sulfur, and charcoal, and was first used for pyrotechnics and military purposes.

The invention of gunpowder was a major breakthrough in the history of ancient Chinese science and technology, and had a profound impact on the military, cultural and social development of mankind. Movable type printing: Movable type printing is a technique of printing words and patterns onto paper and first appeared during the Tang Dynasty.

Compared with woodblock printing, movable type printing can print a large number of words and patterns more quickly and accurately, and plays an important role in the dissemination of culture and knowledge.

Hello dear, the four major inventions refer to papermaking, the compass, gunpowder, and printing. The theory of the four great inventions originated from the British sinologist Joseph Needham, and the four great inventions had a huge role in promoting the political, economic, and cultural development of ancient China.

Hello, the four great inventions refer to the four inventions that have a significant impact on human civilization in ancient China, they are:1Papermaking:

During the Han Dynasty, Qin Rang judged Cai Lun to improve papermaking techniques, making writing materials more convenient and widely disseminated. 2.Compass:

During the Northern and Southern Dynasties (c. 200-589), the Chinese invented the compass to make navigation more accurate and safer. 3.Gunpowder:

During the Tang Dynasty, the Chinese invented gunpowder, which could be used to make fireworks, artillery and other firearms, which had a profound impact on military warfare and cultural entertainment. 4.Movable type slippery knowledge printing:

During the Song Dynasty, Bi Sheng invented movable type printing, which replaced the original woodblock printing and achieved high efficiency, popularity, and diversity of printing.

The answer is as follows: China's four great ancient hair and Lu Zhi Yu Ming are rotten refers to papermaking, compass, gunpowder, and printing. The four great inventions are the intellectual achievements and science and technology of China's early rolling generation, which 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, and have had a huge impact on the history of the development of world civilization.
