Four ancient inventions in China have long been known to women and children all over the world. If someone told you that compasses, papermaking, gunpowder and movable type printing could not fully represent the highest level of ancient Chinese science and technology, what would you think? After more than a year of preparation, "Miracle Heavenly Creations - China ancient inventions and cultural relics exhibition" recently in China Science and Technology Museum new museum. This exhibition, co-organized by the State Administration of Cultural Heritage and China Association for Science and Technology, shows the great inventions and inventions of ancient China with silk, bronze, paper-making, printing and porcelain as the main four cultural relics. It has been greatly welcomed by the exhibitions. Yesterday, Zhao Feng, the chief curator of the silk department and vice curator of the China Silk Museum, returned to Hangzhou. He told reporters that the original four inventions can no longer completely represent the highest level of ancient Chinese science and technology. This exhibition is the first collective appearance of the new "Four Great Inventions." According to Zhao Feng introduction, the so-called new big four inventions, with the four inventions in terms of the ship. About 400 years ago, the British philosopher Francis Bacon pointed out that the three inventions of printing, gunpowder and compass have changed the whole picture and situation of things all over the world. "Missionaries to China, Sinology In the comparison between Japan and China, he pointed out that "we must always remember that they do not have the same excellence as printing, papermaking, compasses, and gunpowder Invention. " Once the four traditional inventions were proposed, some scholars proposed new ideas. Dr. Joseph Needham, a world-renowned historian of science and technology, once listed 26 technologies that China imported into the West and believed that the important inventions in China are not limited to these four inventions. According to Zhao Feng, silk is one of the important inventions in ancient China. Compared with other inventions, silk has the earliest appearance, the widest application, the farthest spread, and the top four features. It appears in the Neolithic Age and is of the same age as the Chinese civilization. It is used all over the world to serve the people. It spreads the world and the Silk Road becomes the channel for the exchange between the East and the West. It has the highest technical content and the number of inventions and inventions. In this exhibition, the silk section focuses on six invention patents that dominate the world history of textiles. One is the domestication of wild silkworms into silkworms; this is an extremely significant invention in the history of biology. Only two types of insects, silkworm and bee, have been domesticated in human history. The second is the invention of pedal loom, since then, "machine" word not only become a general term for all machines and machines, and become witty, alert, clever and smart and intelligent pronouns; third is a set of fabric structure system, it is precisely because of this set of structure Design, there was a silk silk brocade Variety silk; fourth is to control the cycle of jacquard program, which is the most magical silk technology part of this line made of flowers spread to Europe after the development into a Punched paper version, and then on the telegraph and early invention of computing machines have an impact; five is clip Valerian, this invented in the Tang Xuanzong colorful anti-dye printing technology has been handed down to today; six is ​​lock embroidery, although only one Handcraft skills, but in the world of forest art is unique. Zhao Feng also said that printing and papermaking are closely related to silk. The earliest typography in the Han Dynasty, was used on silk. The Tang Dynasty only appeared in the engraving printing on paper. In addition, the earliest paper was a thin layer of silk fiber, and later, after adding other plant fibers, it became a paper with a certain strength that could be used for writing. At present, Zhao Feng is participating in the Compass Project. This is a major scientific project listed in the Outline of the National Eleventh Five-Year Plan for Cultural Development. It is a major cultural project following the exploration of the source of Chinese civilization. Experts will study how many ancient Chinese inventions in the end, this exhibition can be said that the project's rehearsal.
