Who were the inventors of Yuan Dynasty, Ming Dynasty and Qing Dynasty?

Guo Shoujing was a famous scientist in Yuan Dynasty in China. He invented many tools, such as simple instruments, and made an excellent calendar, calendar time. Huang Daopo (1245— 1330) was a cotton weaver in the Yuan Dynasty. Xu Guangqi (1562- 1633), Zi Xian, No. Ming Songjiang people, Han nationality. Thirty-two years of Wanli (1604), Jinshi. Know astronomy, calendar and firearms. Xu Guangqi's achievements in astronomy are mainly the revision of calendar and the compilation of Chongzhen almanac.

Zhao Shizhen (1552 ——1611), inventor of firearms in Ming Dynasty, was born in Yueqing City (county). His inventions such as "rocket sliding", "electric kitchen knife" and "eagle flying gun" played a powerful role in War of Resistance against Japanese Aggression at that time. His works, such as Artifact Spectrum, Preparing Frontier Stations and Instruments, have been highly praised by the famous British scholar Joseph Needham. However, Zhao Shizhen entered his official career by virtue of his exquisite calligraphy art. According to records, when he was studying in imperial academy, he occasionally wrote poems for eunuchs and gave them to Emperor Wanli for "great praise", so he was appointed as the director of crack hon temple in the sixth year of Wanli (1578) and was "the last person to write Han books".

Xu shou (18 18 ~ 1884), a scientist in Qing dynasty, was good at mathematics and engineering technology. Together with contemporary scientist Hua, he built the first steam engine and wooden hull ship "Huangpi" in China, which is a new achievement in the modern history of science and technology in China. 187 1 year, Xu Shou translated and published six books including Chemical Monitoring Sources.

Dai Zi, inventor of firearms in the Qing Dynasty, and Huang Lvzhuang, inventor of firearms in the Qing Dynasty (1656-? Years), Yangzhou, Jiangsu. Smart since childhood, especially like to come up with new ideas. When he was seven or eight years old studying in a private school, he secretly put the carpenter's knife and chisel on his back and carved a wooden statue about an inch high. Put Woodenhead on the table, it can walk automatically, and its hands and feet will move. The audience said it was amazing. When Huang Lvzhuang was in his teens, his father died, and Huang Lvzhuang went to Guangling (now Guangling District of Yangzhou City) to go to his cousin Dai Rong (word, 1656-? Born in the same place, at the same time in the same year (strange! )。 So he came into contact with western mathematics and physics, and his production technology has been greatly improved. He once made some little things for himself to play with, and people paid a high price for them. However, he was physically exhausted and could not bear too much labor, so he had to give up this hobby, so his works were few. Dai Rong once saw Huang Lvzhuang build a two-wheeled vehicle, which was more than three feet long, and one person could sit without pushing. If it stops, as long as you pull the crank next to the shaft with your hand, it will continue to walk, and it can walk 80 miles every day. Huang Lvzhuang also made a wooden dog, which can be rolled up like a real dog by the door. When someone enters the door and touches the mechanism, the wooden dog will keep barking, and the barking sound is similar to that of a real dog, so it is difficult for people to distinguish its authenticity. He also made a wooden bird, put it in a bamboo cage, and danced and sang like a thrush, which was even more touching. Huang Lvzhuang also made a container for water. When water is poured into the container, it will shoot from bottom to top like a line, five or six feet high, and the water will not break after an hour. He also made many other toys, which can't be recorded. Some people see that Huang Lvzhuang can produce so many strange things, and they suspect that he must have different books or biographies. But Dai Rong spent a long time with him and didn't see any different books. Dai Rong also asked Huang Lvzhuang who he learned the technology from. But Huang Luzhuang told him that he had no master at all. In fact, Huang Lvzhuang likes to think and is good at thinking. Dai Rong once talked to him, but he listened carefully. If he can't solve the problem, he will stay up all night and sit-ups until he finds the answer. Huang Lvzhuang also designed a cold and hot detector (i.e. thermometer, which can separate the climate and test the medicinal properties), a dehumidifier (i.e. hygrometer, which can predict the sunny or cloudy weather) and a condenser (i.e. condenser, which can reach five or six feet in diameter and is illuminated by Yi Deng at night), which is very useful. In winter, people sit under the light to keep warm (such as basking in the sun), optical instruments such as telescopes and microscopes, and multistage spiral waterwheels (used for farmland irrigation).
