Shen Kuo is a famous scientist in history, what did he do?

Shen Kuo improved the armillary sphere, and also deduced the cause of the solar and lunar eclipses at that time, which was not easy at that time, but it was a pity that he took fame and fortune too seriously.

Shen Kuo was a famous scientist in the Northern Song Dynasty, he mainly resisted the attack of Western Xia, and he also built water conservancy to benefit the country and the people, and the Taiping car survived in the world.

Shen Kuo has been hailed as "the most outstanding figure in the entire history of Chinese science". His masterpiece "Dream Creek Writings" is very rich in content, and it can be said to be the culmination of the scientific achievements of the previous generation.

Shen Kuo (1031–1095) was a scientist and writer during the Northern Song Dynasty of China, known for his versatility and erudition. He was mainly engaged in research in the fields of water conservancy, metallurgy, geography, meteorology, etc., and made great contributions to the development of science and technology and culture in the Northern Song Dynasty. There are many things that Shen Kuo invented and judged, among which the more famous ones are:

1.Luoyang shovel: A water conservancy tool designed and manufactured by Shen Kuo to increase the drainage capacity of the river and prevent flooding of the river.

2.Catapult: Shen Kuo improved the design of the catapult to increase its attack range and attack power, and applied it to the military.

3.Bicycle Cycle: Shen Kuo invented a human-powered means of transportation that is similar in principle to modern bicycles, but with a narrower range of use.

4.Improving ironmaking technology: Shen Kuo has made a lot of contributions to ironmaking technology, inventing some new iron ore beneficiation methods and ironmaking technologies, making ironmaking faster and better quality.

5.Improvement of paper making technology: Shen Kuo invented some new technologies for making high-quality paper, which made the paper tougher and more wear-resistant, and also reduced production costs.

In Shen Kuo's physics, it is the study rather than the invention: mechanics, acoustics, optics, magnetism, and other phenomena.

1.In terms of magnetism, Shen Kuo pointed out in "Pen Talk" that the compass.

It was made by Fang Jia grinding an iron needle with a magnet to magnetize the iron needle. He described the four installation methods of the compass at that time, namely the water drifting method, the nail method, the bowl lip method, and the hanging line method, and compared the advantages and disadvantages of these four methods, pointing out that the water drifting, the nail method or the bowl lip setting method is easy to fall, and the hanging line method is the best, indicating that he has observed and experimented with these four methods. Through observation and experimentation, he discovered that the magnetic needle has a pointer, which also points to the north.

The guide needle is not always guided, but always slightly easterly. This is the earliest definitive record of the northern compass and the Earth's magnetic declination, a century before Europe.

2.In terms of optics, Shen Kuo carried out concave mirror imaging experiments. Through experiments, he pointed out that there is a place called "Barrier Orange Old Knowledge" in the middle of the concave mirror photograph, and in this place, the photograph is correct; On top of this, you can't see anything; In addition to that, he did find the focus of the concave mirror.

He also made careful observations and studies of convex and flat mirrors. He points out that convex mirrors reduce the illuminated faces, so the mirrors are small but can accommodate all the faces.

3.In terms of acoustics, Shen Kuo conducted sound resonance experiments. He cut out a small figure out of paper, placed it on the basic strings of the harp, plucked the corresponding overtone strings, and the little man beats; When the other strings are plucked, the paper figure does not move. Similar experiments in the West did not appear until the 17th century.

In addition, Shen Kuo also studied mirages, rainbows, thunder and lightning, ** rhythm, etc. and put forward their own opinions.

Shen Kuo (1031-1095 AD), Qiantang, Hangzhou.

Motion. In the fifth year of Ning (1072), he was promoted to Zhejiang, and in the following year, he went to Zhejiang, Zhejiang to inspect water conservancy and servants. Ning sent an envoy to the Liao State.

In eight years, the Liao's claim to land was refuted. In the following year, he was appointed as a bachelor of Hanlin and the third envoy of the whole country, and rectified the salt administration of Shaanxi. After knowing Yanzhou (now Yan'an, Shaanxi), he strengthened the Western Xia.

defense. In the fifth year of the Yuan Dynasty (1082), the Song army was defeated by the Western Xia in the Battle of Yongle City and was demoted. In his later years, he wrote "Meng Qian's Writings".

Shen Kuo founded the gap accumulation technique and the circle technique; discovery of magnetic declination; improved armillary spheres; Reveal resonance phenomena, etc. Shen Kuo, the word Cunzhong, Mengxi Zhangren, Han Shan Zhao, Hangzhou Qiantang County, Northern Song Dynasty, scientist. Shen Kuo has devoted his life to scientific research, and has deep attainments and outstanding achievements in many disciplines, and is known as "the most outstanding figure in the history of science in China".

Shen Kuo was born in the family of eunuchs, and traveled with his father when he was a child. In the eighth year of Jiayou, he was awarded the manager of Yangzhou to join the army. Song Shenzong participated in the Xining reform, and was valued by Wang An's stone tools, and successively served as the crown prince Zhongyun, the inspection of the Zhongshu Torture Room, the promotion of the Heavenly Prison, the review of the History Museum, and the envoy of the three divisions.

Achievement profile. Shen Kuo uses the method of analogy and induction, based on the volume formula, to solve the cumulative number of discontinuous individuals into continuous whole values to solve, and has the idea of using a continuous model to solve the discrete problem.

Circumference: Circumference, in fact, refers to the method of finding the arc from the string, and its main idea is to give a more practical approximate formula for the arc sagittal relationship of the circle by the straight instead of the curve.

Shen Kuo invented the "Twelve Qi Calendar", promoted the study of ancient astronomy, and had an in-depth study of the compass, and also discovered the first geomagnetic declination on the world's weighing manuscript branches, more than 400 years earlier than Columbus discovered the phenomenon of magnetic declination when he crossed the Atlantic.

Shen Kuo was the Northern Song Dynasty.

**, scientist, a lifelong dedication to scientific research, in many disciplines have deep attainments and outstanding achievements, known as "the most outstanding figure in the entire history of Chinese science". His masterpiece is "Dream Creek Writings".

The content is rich and the culmination of the scientific achievements of the previous generation, and it has an important position in the history of world culture.

Shen Kuo made meticulous observations of celestial phenomena and made some new discoveries and observations. Shen Kuo also observed in detail the trajectory of the five stars and the scene when the meteorite fell, and measured the North Star.

The speculum was designed at the true distance from the North Celestial Pole, and the rough conclusion of the Pole Star at that time was "more than three degrees from the Celestial Pole" was obtained.

Shen Kuo discovered a brown liquid that the locals called "stone paint" and "stone grease", and used it to cook on fires, light lamps and keep warm. Shen Kuo understood the nature and use of this liquid, and gave it a new name, petroleum.

Shen Kuo (c. 1033-1097).

Scientist of the Northern Song Dynasty of China. The word is in storage. A native of Qiantang (now Hangzhou, Zhejiang).

In the first year of Zhihe (1054), Shen Kuo entered the office with his father's shadow and served as the chief secretary of Shuyang County, Haizhou (now Jiangsu). The construction of canals and weirs and the development of farmland have made considerable political achievements. In the third year of Zhiping (1066), he entered Beijing to edit the books of the Zhaowenguan.

During the Xining period, Zhao Ji of the Song Dynasty Shenzong used Wang Anshi as his prime minister and was determined to reform, and Shen Kuo also participated in many activities at that time. In the summer of the eighth year, the Liao people intended to occupy the border land along the Hedong Road in the Song Dynasty, causing border disputes. Shen Kuo was an envoy to negotiate as a bachelor in Hanlin.

After arriving at the Liao court, he argued with reason and debated 6 times, but the Liao people could not give in and returned with success. On the way to the envoy, he painted the dangers of the mountains and rivers of the Liao State and the customs and people's feelings, and made it into the "Copy of the Envoy Map", which was published in the imperial court. In the second year of Yuanyou (1087), he completed the "map of the counties and counties of the world" that had been ordered to be compiled in the ninth year of Xining, and named it "The Map of Keeping Orders".

In the third year of Yuanyou, Shen Kuo moved to Runzhou (now Zhenjiang, Jiangsu), and managed the garden land he had purchased before, named "Mengxi Garden", and died after living in seclusion here for 8 years. During this period, he wrote his scientific masterpiece "Mengxi Writings", as well as the agricultural work "Mengxi Forgotten Records" (lost), and the medical work "Good Prescription".
