This great scientist is named Zhang Heng. Zhang Heng is a famous astronomer, geographer, mathematician, etc. in Chinese history. He is an all-round talent and has high attainments in many fields. The works he wrote and the results of his inventions throughout his life have made great contributions to the development of China. He is the only scientist in ancient China who is called a saint. Not only that, his influence in the world is great.
Zhang Heng’s background was not very good when he was young, and his family was relatively poor. However, Zhang Heng loved reading very much and often absorbed the knowledge from books. When Zhang Heng was 16 years old, he left home and came to the world to study. Zhang Heng is a talented and capable person. He has a calm personality and does not make friends with ordinary people. At that time, Zhang Heng was a being different from ordinary people. He would not indulge in secular life, but liked to study the reasons for the existence of all things in the world, such as astronomy, geography, mathematics, etc.
After that, Zhang Heng eventually became the Taishi Ling of the Eastern Han Dynasty due to his outstanding abilities. During his 14 years in office, he produced many major scientific achievements. For example, Zhang Heng invented the wind seismograph used to detect earthquake directions in history. Because of the invention of this instrument, the Eastern Han Dynasty accurately measured the direction of earthquakes and reduced the damage caused by earthquakes to a great extent. You know, the seismometer invented by Zhang Heng was more than 1,700 years earlier than those invented abroad.
In addition to the wind seismometer, Zhang Heng also invented the armillary sphere, which was used to measure the coordinates of the outer surface of the celestial body. It can be seen that Zhang Heng's thoughts were not imprisoned by China's feudal thoughts at all, but were particularly advanced. Zhang Heng's scientific invention transcended the subjective study of things and instead studied the vital signs of the objective world. If we only saw the road in front of us, Zhang Heng looked up and saw the distant sky.
