Zhang Heng is from which dynasty? What dynasty is Zhang Heng from?

Zhang Heng was a great astronomer, mathematician, inventor, geographer, and writer in the Eastern Han Dynasty.

Zhang Heng's tomb is located 25 kilometers north of Nanyang City, Henan Province, 20 meters west of Shiqiao Town, Shiqiao Town, 20 meters west, for the national key cultural relics protection unit. According to historical records, the cemetery was built magnificently in the Han Dynasty, Weng Zhong and stone beasts were opposed, and the ancestral temple was majestic and magnificent.

After the war, the past victories were gone. After the founding of the People's Republic of China, in 1956, the Zhangheng Cemetery and the "Pingzi Reading Platform" were rebuilt. The stone tablets of the Ming and Qing dynasties in front of the tomb were stamped with the stele tower.

And in front of the tomb 1 monument, the inscription was written by Guo Moruo, the former president of the Chinese Academy of Sciences. The site of the reading platform in the north of the tomb was also rebuilt to erect a monument.

He was a great astronomer, mathematician, inventor, geographer, cartographer, writer, and scholar in the Eastern Han Dynasty.

1. Zhang Heng is a figure in the Eastern Han Dynasty.

2. Zhang Heng (78-139), the word Pingzi. Han nationality, Nanyang Xi'e (now Shiqiao Town, Nanyang City, Henan), one of the five saints of Nanyang, and Sima Xiangru, Yangxiong, Bangu and known as the four masters of Han Fu. During the Eastern Han Dynasty of China, he was a great astronomer, mathematician, inventor, geographer, and writer, and successively served as Langzhong, Taishiling, Shizhong, and Hejian in the Eastern Han Dynasty.

In his later years, he entered the court as Shangshu due to illness, and died in the fourth year of Yonghe (139) at the age of sixty-two. During the Northern Song Dynasty, he was posthumously named Western Obo.

3. In astronomy, Zhang Heng is the author of "Lingxian" and "Armillary Chart Annotation", mathematical works such as "Theory of Arithmetic", and literary works are represented by "Erjing Fu" and "Guitian Fu". "Sui Shu Jing Ji Zhi" has 14 volumes of "Zhang Heng Collection", which has been lost for a long time. Zhang Pu of the Ming Dynasty compiled the "Zhang Hejian Collection", which was included in the "Collection of One Hundred and Three Families of the Six Dynasties of the Han and Wei Dynasties".

Fourth, in terms of science, Zhang Heng has made outstanding contributions to the development of Chinese astronomy, mechanical technology, and science, invented the armillary sphere and the geodynamic sphere, and is one of the representatives of the armillary theory in the middle of the Eastern Han Dynasty. Known as the "Mu Sheng" (Ke Sheng) by later generations, because of his outstanding contributions, the United Nations Astronomical Organization named a crater on the far side of the moon "Zhang Heng Crater", and the asteroid No. 1802 in the solar system was named "Zhang Heng Star".

5. In addition, there are several names that are also named Zhang Heng, such as the second generation of Heavenly Master Dao (commonly known as Wudou Midao) of the Taoist sect in the late Eastern Han Dynasty.

Zhang Heng (78-139), whose name is Pingzi, was a native of Nanyang Xi'e (now Shiqiao Town, Nanyang City, Henan). He was a great astronomer in the Eastern Han Dynasty and made indelible contributions to the development of astronomy in China. In mathematics, geography, painting, and literature, Zhang Heng also showed extraordinary talent and extensive knowledge. Zhang Heng is one of the representatives of the Hun Tian Theory in the middle of the Eastern Han Dynasty; He pointed out that the moon itself does not emit light, and that moonlight is actually a reflection of daylight; He also correctly explained the causes of lunar eclipses and recognized the infinity of the universe and the relationship between the speed of the planets and their proximity to the Earth.

Zhang Heng observed and recorded 2,500 stars, created the world's first leaky armillary sphere that can perform celestial phenomena more accurately, the first instrument to test the first - the wind and ground motion instrument, and also created a guide car, an automatic memory drum car, a wooden bird that flew several miles, and so on. Zhang Heng is the author of a total of 32 scientific, philosophical, and literary works, including astronomical works such as "Lingxian" and "Lingxian Tu". In order to commemorate Zhang Heng's achievements, people named a crater on the far side of the moon as "Zhangheng Crater", and asteroid 1802 as "Zhangheng Asteroid".

Guo Moruo, a famous Chinese writer and historian in the 20th century, commented on Zhang Heng: "Such a well-rounded figure is rare in world history. Later generations called Zhang Heng a wooden saint (Kesheng).

Zhang Hengzi Pingzi. A native of Xi'e County, Nanyang County (now Nanyang, Henan). Born in the first three years of the Eastern Han Dynasty (78 AD); He died in the fourth year of Yonghe (139 AD).

Astronomy, mechanical technology, **science. I bs Koreans mess with their ancestors.

1. Zhang Heng was a figure in the Eastern Han Dynasty in ancient China, a native of Xi'e County, Nanyang County, during the Eastern Han Dynasty, that is, a native of Shiqiao Town, Nanyang City, Henan Province. Zhang Heng was born in a big family, Zhang Heng studied hard since he was a child, and he was able to make articles when he was a teenager. At the age of sixteen, Zhang Heng left his hometown and began to travel around, first to Sanfu, then to Luoyang, the capital of the Eastern Han Dynasty, where he met the famous scholar Cui Ming.

2. In Luoyang, Zhang Heng taught himself the "Five Classics", and also began to like to study astronomy, geography, mechanical manufacturing and other knowledge, which laid a solid foundation for the later manufacture of armillary spheres. During the first year of the Han Dynasty and Emperor Yongyuan, Zhang Heng was promoted to filial piety, but he did not accept the call of the government several times. In the twelfth year of Yongyuan, Nanyang Taishou Baode invited Zhang Heng to be the chief bookkeeper, Zhang Heng worked under him for eight years, and after Baode was transferred, Zhang Heng resigned and went home, concentrating on astronomy, calendrical calculations, yin and yang at home.

3. Emperor An of the Han Dynasty gave him the characteristics of the bus to enter Beijing after learning of Zhang Heng's talent, appointed Zhang Heng as Langzhong, and later promoted to Taishi Ling, so Zhang Heng studied Yin and Yang more diligently, and developed an armillary sphere with unprecedented achievements after combining the experience of his predecessors, which is also one of Zhang Heng's famous inventions.

4. In the fourth year of Yonghe, Zhang Heng died at the age of sixty-two, and later in the third year of the Song Huizong Grand View, Zhang Heng was also posthumously awarded the title of West Ombo because of his academic achievements, and later generations also called it "Mu Sheng" in order to commemorate Zhang Heng, and Zhang Heng's academic achievements also have a great impact on today's people.

Geodynamic Instrument The geokinetic instrument is another masterpiece of the Han Dynasty scientist Zhang Heng. In the Eastern Han Dynasty in which Zhang Heng lived, ** was more frequent. According to the records of the Five Elements of the Book of the Later Han Dynasty, from the fourth year of Emperor He Yongyuan (92 AD) to the fourth year of Emperor Yanguang (125 AD), a total of 26 major ** occurred.

** Districts are sometimes as large as dozens of counties, causing land fissures, landslides, flooding of rivers, and collapse of houses, causing huge losses. Zhang Heng has a lot of personal experience with **. In order to grasp the national dynamics, after years of research, he finally invented the geodynamic instrument in the first year of Yangjia (132 AD) - the world's first ** instrument.

According to the "Biography of Zhang Heng in the Book of the Later Han Dynasty", the geodynamic instrument is "made of fine copper, with a diameter of eight feet", "shaped like a wine bottle", with a raised round cover, and the appearance of the instrument is engraved with seal inscriptions and figures such as mountains, turtles, birds, and beasts. Inside the instrument, there is a copper "capital column", and there are eight passages next to the column, which become "eight paths". There is a "tooth machine" in the road.

There are eight dragons cast around the outside of the body, with their heads facing down and their tails facing upwards, arranged in eight directions: east, south, west, north, southeast, northeast, southwest and northwest. The faucet is connected to the engine in the internal tunnel, and each faucet has a copper ball in its mouth. Facing the dragon's head, eight toads squatted on the ground, each with their heads raised and their mouths open, ready to take on the copper ball.

When ** occurs in a certain place, the "capital column" inside the geodynamic instrument is tilted, touching the dental machine, making the faucet in the direction of ** open its mouth, spit out the copper ball, and fall into the mouth of the copper toad, causing a loud sound. So people can know the direction in which ** is happening.

On the third day of the second month of the third year of Emperor Yonghe of Hanshun (138 AD), a dragon machine of the geodynamic instrument suddenly started and spit out a copper ball. At that time, the people in the capital did not feel the slightest sign of the trouser debate, so some people began to talk about it, blaming the ground for not working. A few days later, someone in Longxi (now southeastern Gansu Province) reported to Chunbian, confirming that ** had indeed happened there a few days ago, so people began to be extremely convinced of Zhang Heng's superb skills.

Longxi is more than 1,000 miles away from Luoyang, and the geodynamic instrument is correctly marked, indicating that its seismic sensitivity is relatively high.

According to the research of scholars, Zhang Heng had already used the principle of inertia in mechanics at that time, and the "Du Zhu" actually played the role of inertial pendulum. At the same time, Zhang Heng must have some understanding of the propagation and directionality of the first wave, these achievements were very remarkable at that time, and Europe did not make similar instruments until 1880, more than 1,700 years later than Zhang Heng's invention.
