The geodynamic instrument was invented by Zhang Heng.
Zhang Heng was a scientist in the Eastern Han Dynasty in China, as well as an astronomer, mathematician, inventor and geographer. Zhang Heng, whose name is Pingzi, is a native of Xi'e County, Nanyang County, and is now a native of Shiqiao Town, Nanyang City, Henan Province. In the Eastern Han Dynasty, the geodynamic instrument was mainly used to predict the time of occurrence in advance, which could protect people's lives and property safety in time.
Zhang Heng has made great contributions to the development of Chinese astronomy, mechanical technology, and science, and Zhang Heng invented the armillary sphere and the geodynamic instrument. Zhang Heng is also one of the representatives of the Hun Tian theory in the middle of the Eastern Han Dynasty, and is called the Mu Sage by later generations. Zhang Heng has many works, such as "Lingxian", "Erjing Fu" and so on.
Zhang Heng Profile
Zhang Heng's family has been a local surname for generations, and his grandfather, Zhang Kan, has been determined since he was a child, known as the Holy Child, and once gave the family heirloom to his nephew.

Zhang Heng had written "Zhou Guan's Exegesis", and Cui Ying thought that there was no difference between the explanations of other Confucian scholars. He also wanted to follow Confucius's "Yi" to correct the defects of "Yi" and "Xiang", but he never completed it. His poems, fus, inscriptions, seven words, and "Lingxian", "Yingjian", "Seven Arguments", "Inspection", "Hanging Fiber Touch" (one work "Xuantu") and other works, a total of 32 articles.
"Han Poems" has nine of his poems, and "Sui Shu Jing Ji Zhi" has 14 volumes of "Zhang Heng Collection", which has been lost for a long time. The Ming dynasty Zhang Pu compiled the "Zhang Hejian Collection", which was included in the "Han and Wei Six Dynasties One Hundred and Three Collections".

The geodynamic instrument was invented by Zhang Heng, a scientist in the Eastern Han Dynasty, and Zhang Heng invented the geokinetic instrument because it was frequent in the country at that time, causing great losses to people's lives.
Zhang Heng personally felt this pain and decided to study an instrument to grasp the dynamics of the **, after a long period of research in the first year of Yangjia invented the wind geodynamic instrument, this geodynamic instrument is the world's first geokinetic instrument.
There are eight directions of the geodynamic instrument, they are east, south, west, north, southeast, southwest, northeast, northwest, each direction has a dragon head with a dragon ball in its mouth, and there is a toad corresponding to each dragon head. If there is a ** occurrence on either side, the dragon ball contained in the dragon's mouth in that direction will fall into the toad's mouth, so that the direction of the occurrence of ** can be measured.
Origin:
Zhang Heng lived in the Eastern Han Dynasty of the Han Dynasty, ** more frequent. According to the records of the Book of the Later Han Dynasty and the Five Elements Chronicles, 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 ground cracks and landslides, collapsed houses, and flooded rivers, 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 wind and ground motion instrument in the first year of Yangjia (132 AD), the world's first ** instrument. At that time, this instrument was used to successfully monitor and report a ** incident in the western region, which attracted the attention of the whole country.
This is more than 1,700 years earlier than the history of Western countries using instruments to record **.

Zhang heng.
The geodynamic instrument is the masterpiece of Zhang Heng, a scientist in the Eastern Han Dynasty of China, when it was more frequent, in order to grasp the dynamics of the country, he finally invented the world's first geodynamic instrument in the first year of Yangjia after many years of research, called the wind geodynamic instrument. Due to the long history, Zhang Heng's geodynamic instrument has been lost, leaving only more than 100 words of written records.
Principle research. 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.

The geodynamic 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 Book of the Later Han Dynasty and the Five Elements Chronicles, 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 guessing and grinding 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, Zhaoxian 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. Seismograph.
There are two popular versions of the structure of the geodynamic instrument: Wang Zhenduo's model, that is, the "Du Zhu" is a cylinder similar to an inverted wine bottle, and the mechanism that controls the dragon's mouth is around the "Du Zhu". This model has recently been largely rejected. >>>More
The geokinetic instrument is an ancient thing, and now it is useless at all - at 14:28 on May 12, 2008, it occurred in Wenchuan, Sichuan Province (east longitude, north latitude). **Caused most parts of the country to feel, many netizens are questioning why there is no forecast today**, but when the reporter checked the online information, he found that many phenomena before indicated that there would be**. On May 9th, a netizen posted on the post bar: >>>More
The geodynamic instrument was made by Zhang Heng.
What is the role of Zhang Heng's geodynamic instrument? Why was it removed from history textbooks? In recent years, the world's ** has happened frequently, and there have been Weibo hot searches and ** shadows, as a person who has grown up in Chinese education, it is not difficult to think of Zhang Heng and his Chi Dongxi when it comes to mentioning**. >>>More
The working principle of Zhang Heng's geodynamic instrument is mainly based on the ancient theory of "waiting for qi", that is, the way of "the law of ash accounting", so it is called "waiting for the wind and geodynamic instrument". A large pillar is buried deep in the ground in the selected position, like the central pillar of the grass house when ancient people built houses, and this pillar is used to sense ** waves. In order to avoid the influence of the ground environment on the "capital column", hollow out the column at an appropriate depth, or dig the earth well first, and then bury the large column into compaction, and separate the column from the well wall at a considerable distance from the ground, so as to avoid the interference from the ground influence on the "capital column". >>>More
