Seismograph. Zhang Heng is a famous writer and scientist in the Eastern Han Dynasty in China, and his deeds of inventing the geodynamic instrument are not only recorded in the history books, but also included in the textbooks, and almost everyone is familiar with them in China. In addition to the invention of the geodynamic instrument, Zhang Heng also has many ingenious ideas and productions, which have made important contributions to the development of astronomy, meteorology, mathematics, and mechanical production in China.

Character characteristicsAlthough he was excellent in learning, Zhang Heng was not keen on fame, and it was not until he was 23 years old that he agreed to the invitation of Nanyang County Taishou Baode to serve as the chief secretary of Nanyang County. After returning to Nanyang, he carefully studied astronomy, yin and yang, calendar and other aspects of learning, which attracted the attention of Emperor An of the Han Dynasty, and recruited him as Langzhong, and soon promoted him to Taishi Ling, specializing in the management of the time and ephemeris. During his tenure as Taishi Ling, Zhang Heng wrote works such as "Lingxian" and "Theory of Calculation", and also made an armillary sphere.

The things invented by Zhang Heng include a geodynamic instrument, a guide car, and an improved armillary sphere. Zhang Heng is a great astronomer, mathematician, inventor in the Eastern Han Dynasty of China, etc., he has made great contributions to the development of Chinese astronomy and science, and is known as the "Wood Sage" by later generations.

Zhang Heng was a great astronomer, mathematician, inventor and so on in the Eastern Han Dynasty of China. He made great contributions to the development of Chinese astronomy and science, invented the geodynamic instrument, the guide car, and improved the armillary sphere, and was praised as the "Wood Sage" by later generations.

In 132 AD, Zhang Heng invented the earliest geodynamic instrument, that is, the wind geodynamic instrument, it has eight directions, every other direction has a dragon with copper beads in its mouth, and there is a toad with a mouth corresponding to it under the dragon, as long as there is a ** occurrence on any side, the copper beads contained in the corresponding dragon's mouth will fall into the toad's mouth. Sparrow's edge.

The armillary sphere is an improvement on the basis of the armillary sphere invented by Geng Shouchang in the Western Han Dynasty, which is mainly used for observing celestial bodies. The function of the compass is not much different from that of a modern compass, consisting mainly of one or two two-wheeled one-wheeled carts, and no matter which direction the car is facing, the arms of the wooden people inside are pointing south.

Zhang Heng invented the armillary sphere, the geodynamic instrument, the ruilun pod, the guide car, the Jili drum car, the solo flying wood carving, and the topographic map. Zhang Heng was a great astronomer, mathematician, inventor, geographer, and writer in the Eastern Han Dynasty. In astronomy, Zhang Heng is the author of "Lingxian" and "Armillary Illustrium"; Mathematical works include "The Theory of Arithmetic"; Literary works are represented by "Erjing Fu" and "Guitian Fu", etc., and are known as the "Four Masters of Han Fu" together with Sima Xiangru, Yang Xiong, and Ban Gu.

Zhang Heng, whose name is Pingzi, a native of Nanyang and Xi'e, has studied hard since he was a child, and left his hometown to study abroad after the age of 16.

At the age of 58, he was transferred to serve as the state minister of Liu Zheng, the king of Hejian.

In 139 AD, Zhang Heng died of illness at the age of sixty-two.

Zhang Heng has made outstanding contributions to the development of Chinese astronomy, mechanical technology and science, and is one of the representatives of the armillary theory in the middle of the Eastern Han Dynasty, and is known as the "Wood Saint" 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 1802 asteroid in the solar system was named "Zhang Hengxing". In order to commemorate Zhang Heng, the descendants built the Zhang Heng Museum in Nanyang.

Zhang Heng - Ground motion instrument.

Zhang Heng invented the earliest geodynamic instrument during his tenure as Taishi Ling, called the Houfeng geokinetic instrument. According to the "Book of the Later Han Dynasty, the Biography of Zhang Heng" records: the geodynamic instrument is cast with fine copper, with a circular diameter of eight feet, the top cover is protruding, the shape is like a wine bottle, and it is decorated with the image of turtles, birds and beasts in the Seal Wen Mountain.

There are big pillars, and there are eight roads to close, and the machine is closed. It has eight directions, each with a dragon with a copper bead in its mouth, and a toad corresponding to each dragon. If there is a ** occurrence on either side, the copper beads contained in the dragon's mouth in the direction will fall into the mouth of the toad, so that the direction of the occurrence of ** can be measured.
