Who are the inventors in the world and what did they invent?

Bi Sheng (about 970-105 1 year) was a native of Buyi nationality in Northern Song Dynasty. Yingshan county, Hubei, was born in Qishui County, qi zhou, Huainan Road, Northern Song Dynasty, and died in February of Northern Song Dynasty. Movable type printing was invented by Song Renzong in Qing Dynasty (104 1- 1048). The invention of movable type printing in Bi Sheng is a great revolution in the history of printing and one of the four great inventions in ancient China. It has opened up a broad road for China's cultural and economic development and made great contributions to the development of world civilization.

2, Cai Lun-papermaking

Cai Lun was born in Guiyang County in the Eastern Han Dynasty. In 88 A.D., Cai Lun was promoted to the position of a regular waiter for his contribution to the Queen Mother, and Cai Lun also served as an official in the Party. Cai Lun summed up people's paper-making experience in the past, innovated the paper-making technology, and finally made "Cai Hou Paper". It was reported to the court in A.D. 105, and Emperor Han and Emperor ordered the popularization of his papermaking method. 12 1 year, he committed suicide because of a power struggle.

Cai Lun's papermaking is listed as the "Four Great Inventions" in ancient China, which has made outstanding contributions to the spread of human culture and the progress of world civilization, and has been respected by people for thousands of years. Being regarded as the originator of papermaking and the "paper god" by papermaking workers? .

3. Zhang Heng-armillary sphere and seismograph

Zhang Heng (78-139), born in Xi 'e, Nanyang (now Shiqiao, Nanyang City, Henan Province), was born in Pingzi, Han nationality. One of the Five Saints in Nanyang, Sima Xiangru, Yang Xiong and Ban Gu are also called the Four Masters of Han Fu.

Zhang Heng made outstanding contributions to the development of astronomy, mechanical technology and seismology in China, and invented the armillary sphere and seismograph, which was one of the representatives of the theory of armillary sphere in the middle Eastern Han Dynasty.

Known as the "wood saint" by later generations. Because of his outstanding contribution, the United Nations Astronomical Organization named a crater on the back of the moon as "Zhangheng Crater" and the asteroid 1802 in the solar system as "Zhangheng Star".

Edison obtained 1000 patents for many inventions, such as electric lights, movies, telegrams, telephones, phonographs and photocopiers.

Thomas Alva Edison (1847, February11-1,10, 10/8) was born in Milan, Ohio.

Edison was the first person in human history to use a large number of production principles and electrical engineering research laboratories to patent inventions, which had a great and far-reaching impact on the world. The perfection of his phonograph, movie camera and electric light had a great influence on the world. He had more than 2,000 inventions and 1000 patents in his life. ?

5, Nobel-explosives

Alfred Bernard Nobel (1833 101October 21-18961February10) is a Swedish chemist, engineer, inventor and inventor. Nobel made many inventions in his life and obtained 255 patents, including 129 kinds of explosives.

Nobel built the world's first nitroglycerin factory in Sweden. On the basis of repeated research, a safe explosive with diatomite as absorbent was invented. This kind of safe explosive, called yellow explosive, shows great safety under fire and hammer, which completely dispels people's doubts about Nobel explosive.

After long-term research, he found a substance that is very easy to cause explosion-mercury fulminate. He used mercury fulminate to make explosive detonator, which successfully solved the problem of explosive detonation. This is the invention of detonator. This is a major breakthrough on Nobel's scientific road.

On the basis of the successful development of safe explosives, Nobel began to improve old explosives and research and produce new explosives. Two years later, a new colloidal explosive made of gunpowder cotton and nitroglycerin was successfully developed. This new explosive is not only powerful, but also safer. It can be rolled between hot rollers or pressed into rope shape under hot air.

The invention of colloidal explosives has been widely concerned by the scientific and technological circles. In the face of his achievements, Nobel did not stop. When he learned the advantages of smokeless powder, he devoted himself to the research and development of mixed smokeless powder and developed a new type of smokeless powder in a short time.
