Who is the king of invention in China and who is the king of invention in the world

Cai Lun, if he had not improved papermaking, there would be no paper now, and the theory could not be known to future generations, so it would not be possible to improve and innovate.

The world's king of invention isEdison

Edison was born in Ohio, USA.

The town of Milan is known as the "King of World Invention". He has more than 2,000 inventions, including the gramophone, which had a great impact on the world.

Movie cameras, tungsten light bulbs, etc. In the United States, Edison has 1,093 patents under his name, while he has accumulated more than 1,500 patents in the United Kingdom, France, Germany and other places.

Edison's Early Years:

In 1857, he became interested in chemistry, and he experimented with textbooks in the cellar of his home, often causing frequent accidents.

In 1859, in order to have enough money to buy chemicals and experimental equipment, Edison began to look for work to earn money, and after some hard work he found a job selling newspapers on trains, and traveled between Port Huron and Detroit every day.

In between, he sells newspapers and carries fruit and vegetable business at the same time, but whenever he has free time, he will go to the library to read books.

In 1861, Edison used the money he earned from selling newspapers to buy an old printing press and began publishing the weekly Herald, which he edited

The inaugural issue was printed on a train, and he was both president, journalist, and publisher, as well as a printer and newsboy. On the train where Edison worked, there was a rest room where no one went because of the lack of air circulation, and the room was empty.

Because Edison was running around on the train every day, returning home late every day, and often feeling that there was not enough time, Edison thought that if the rest room was converted into a laboratory, he could conduct experiments on the way back to Port Huron, and with the permission of the conductor, the unmanned rest room became Edison's laboratory.

1. Compass.

Inventor: Unknown.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on an axis, the magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian, the south pole of the magnetic needle points to the geographical south pole (magnetic field North Pole), and the direction can be discerned by using this performance.

2. Papermaking.

Inventor: Unknown, improved by Cai Lun.

Papermaking is one of the four great inventions of China, which was invented in the Western Han Dynasty of the Han Dynasty and improved in the Eastern Han Dynasty of the Han Dynasty. China is the first country in the world to raise silkworms and weave silk. In ancient China, the working people of the superior silkworm cocoons drew silk and weaved silk, and the remaining evil cocoons and disease cocoons were made of silk cotton by bleaching method.

3. Gunpowder. Inventor: Sun Simiao.

Gunpowder is one of the four great inventions of China. It is a substance that can burn rapidly and regularly under the action of appropriate external energy, and at the same time generate a large amount of high-temperature gas. In the military, it is mainly used as the propellant of guns and shells, the propellant of rockets, missiles and other driving devices, and is an important part of ammunition.

An outstanding achievement in the history of human civilization. Gunpowder has become one of the important inventions of human civilization because of its lethality and deterrence, bringing human beings the role of stopping war and security defense.

4. Engraving printing.

Inventor: Bi Sheng.

Engraving printing in the history of printing has the "living fossil" said, Yangzhou is one of the birthplaces of Chinese engraving printing, is the only city in China to preserve a full set of ancient engraving printing technology, the state attaches great importance to the protection of intangible cultural heritage.

The inventors of China's four major inventions are: Cai Lun, Luan Da, Sun Simiao, and Bi Sheng. 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.

1. Papermaking.

Papermaking is one of the four major inventions in China, and it is also one of the outstanding inventions and creations in the history of human civilization, but there are currently two theories about the creation of papermaking, one is created by the working people of the Western Han Dynasty, because "Sanfu Old Things", "Hanshu - Empress Zhao's Biography", "Later Hanshu Jia Kui's Biography" all mention paper. Another theory is that Cai Lun created it, because the paper mentioned in the "Shuowen Jie Zi" was made of silk fibers.

2. Compass.

The compass is also called Sinan, the "Ancient Mine Record" records that Sinan first appeared in the magnetic mountain area of the Warring States Period, its main component is a magnetic needle mounted on the shaft, the magnetic needle can rotate freely under the action of the natural magnetic field, and at the same time always maintain the tangent direction of the magnetic meridian, and the south pole on the magnetic needle points to the geographical south direction, and the ancient people used this performance to identify the direction.

3. Gunpowder. Gunpowder is also one of the important inventions of human civilization, and the invention of gunpowder is the result of the long-term practice of alchemy and medicine in ancient China, and has a history of more than 1,000 years so far. According to the record of "Fan Zi Yeran", gunpowder has been used in the people in China in the Spring and Autumn Period, and in the last years of the Tang Dynasty, gunpowder has been used in the military.

4. Printing.

Printing was the forerunner of modern human civilization, and it provided powerful conditions for the wide dissemination and exchange of knowledge. Printing is divided into woodblock printing and movable type printing, of which engraving printing was invented in the Tang Dynasty and was widely used in the middle and late Tang Dynasty, while movable type printing was invented by Bi Sheng during the Song Renzong period.

1.Professor Shepiro discovered that the whirlpool of the bath water always swirls in the same direction, and after continuous research, the discovery is related to the autobiography of the earth. (Swirl of bathwater).

2.The famous British chemist Boul Yi dropped hydrochloric acid onto the petals of violets. It was discovered that it would change color, and after continuous experimentation, litmus paper was invented. (discoloration of violet).

3.The Austrian doctor found that his son was dreaming when he was sleeping, and after constant observation, he proved that when the sleeping person's eyes were turning, he was indeed dreaming. (Roll of the eyes while sleeping).

4. Newton continued to study and discover gravity from the fall of the apple.

5. When Luban went up the mountain, his hand was scratched by a plant, and he invented the saw.

6、.Edison – Invention of the electric light.

7、.Galileo – Two iron balls hit the ground at the same time.
