Zu Chongzhi lived in which dynasty of the Southern Dynasty

Zu Chongzhi was a native of the Southern Song Dynasty and Qi Dynasty. Originally from Fanyang County. The words are far away.

His grandfather, Zu Chang, served in the Southern Song Dynasty.

Great Craftsman. Zu Chongzhi was famous for his erudition in his youth and entered the Chinese Forestry Province. In the fifth year of the Ming Dynasty, he served as an official in Southern Xuzhou and joined the army in the public government. Enthusiastic about scientific research and invention, he has achieved a series of important results.

At the age of 35, he served as the county magistrate of Lou County. In the last years of Liu Song, he returned to Beijing to serve as a servant of the confessor, and has been serving in Beijing since then. During this period, significant results were achieved in mechanical engineering. Nanqi Yongyuan died in the second year at the age of 72.

Contribute

Zu Chongzhi's life focused on contributing to the cause of science. In terms of the astronomical calendar, the "Daming Calendar" was compiled, and for the first time, the "precession" was officially introduced into the calendar, and the leap method was significantly reformed, and the length of the return year was determined to be days, and the numerical error from the modern measurement was only 50 seconds. At the same time, he discovered the Node Moon and calculated that its cycle time was in days, less than a second short of modern times.

In addition, he reckoned with Mercury.

The conjunction periods of Venus and Mars are much more precise than their predecessors. In mathematics, pi is calculated.

For the first time in the history of mathematics in the world, pi was accurate to seven decimal places. He and his son Zu Heng also completed the calculation of the volume formula of the sphere, and also studied the "open difference power" and "open difference stand", both of which were in a leading position.

The mathematical achievements of the father and son are summarized in the "Fixation Technique".

In a book, it is a pity that it was lost after the Song Dynasty. In terms of machinery manufacturing, the long-lost guide car has been rebuilt, the "thousand-mile boat" has been designed and manufactured, the water mill that uses water power to scoop rice and grind the surface has been created, the transportation tool similar to the "wooden ox flowing horse" has been studied, the timer leaky pot has been improved, and the "coffin" has been manufactured.

In terms of scriptures and literature, the Book of Changes

Zhuangzi and Laozi have made interpretations, annotated the Analects, the Book of Filial Piety, and the Nine Chapters of Chu Chen's Absolute Silver Words, and also wrote ** "Narrative of Differences".

Ten volumes. Zu Chongzhi has devoted his life to the cause of science and deserves to be a superstar in the world's scientific community.

Zu Chongzhi, a native of Fanyang County, was a mathematician and astronomer during the Northern and Southern Dynasties. The ancestors moved to Jiangnan, and their fathers and ancestors were all familiar with calculations, knowledgeable, and respected by the world. Chong Zhishao spread the family business, and the young man Xiang pointed to the era into the Chinese Forestry Province and engaged in academic research.

Since then, he has served as Liu Song and Southern Qi, and has been appointed as a lieutenant of Changshui. He had significant achievements in mathematics, astronomical calendars, and mechanical engineering.

Zu Chongzhi's main achievements are in the three fields of mathematics, astronomical calendar and mechanical engineering. In addition, the history records that Zu Chongzhi is proficient in music and rhythm, good at playing chess, and also writes ** "Narrative Differences". Zu Chongzhi wrote many books, but most of them have been lost.

The most famous thing is to calculate pi, and Zu Chongzhi's son Zu Yuzhi is also a mathematician.

1. Zu Chongzhi (429 500 AD), the character is far away, his ancestral home is Fanyang (in present-day Qi County, Laishui Bureau, Haili, Hebei), he lived in the hall of the Southern Dynasty defeated the Song (420 479 AD) and Qi (479 502 AD) two dynasties.

2. When I was young, I didn't go to any school, and I didn't get any guidance from famous teachers. However, after hard and diligent study, Tong Fuling made outstanding contributions in the fields of mathematics, astronomical calendar, and mechanical manufacturing, and became a very outstanding scientist in the Southern and Northern Dynasties of our country.

Zu Chongzhi was an outstanding mathematician and astronomer during the Northern and Southern Dynasties.

Zu Chongzhi, a native of Fanyang County (now Laishui County, Hebei Province), was an outstanding mathematician and astronomer during the Northern and Southern Dynasties. Born in the Fan Yang Zu clan. He devoted his life to the study of natural sciences, and his main contributions were in mathematics, astronomical calendar, and mechanical engineering.

On the basis of the precise method of exploring pi pioneered by Liu Hui, he actuarially calculated "pi" to the seventh decimal place for the first time, and the "ancestral rate" proposed by him made a significant contribution to the study of mathematics.

Pi is widely used, especially in astronomy and calendars, and all problems involving the circle must be calculated using pi. How to correctly calculate the value of pi is an important topic in the history of mathematics in the world. Ancient Chinese mathematicians attached great importance to this problem and studied it very early.

Family background

From the end of the Western Jin Dynasty to the period of the Sixteen Kingdoms, there was a large-scale war in the north, and the ancestors of Zu Chongzhi migrated from Fanyang County (now Laishui County, Hebei Province) to Jiankang, the capital of the Eastern Jin Dynasty (now Nanjing City, Jiangsu Province), Zu Chongzhi was born in Jiankang, and his grandfather Zu Chang served as the master craftsman of the Liu Song Dynasty, and was an official who managed civil engineering in the imperial court.

Zu Chongzhi has received a good family education since he was a child. His grandfather told him about "fighting and changing the stars", his father led him to read the scriptures and classics, and the influence of his family, coupled with his own diligence, made him have a strong interest in natural science, literature, philosophy, and especially astronomy, and he had a reputation for erudition in his youth.

Zu Chongzhi was from the Northern and Southern Dynasties.

Zu Chongzhi (429-500), the character is far away. Born in Jiankang (now Nanjing), his ancestral home is Fanyang County (now Laishui County, Hebei), and he was an outstanding mathematician and astronomer during the Northern and Southern Dynasties of China.

Before the Han Dynasty, China generally used three as the value of pi, that is, "three diameter one". This is a large error when calculating the circumference and area of a circle. On the basis of the scientific method of using "circumcision" to find pi created by Liu Hui, Zu Chongzhi used the method of opening and density, and after repeated calculations, found that pi is:

Major contributions. In terms of the astronomical calendar, Zu Chongzhi compiled the "Daming Calendar", and debated the implementation of the "Daming Calendar" with the ** at that time, and wrote many refutations. And for the first time, the annual difference was used to calculate the number of days in the month of the node, the number of days in the return year, and the method of measuring the winter solstice by using the Gui table was also invented.

In terms of machinery manufacturing, Zu Chongzhi designed and manufactured many very advanced machinery and equipment at that time, such as guide cars, water mills, timers and thousand-mile ships.

In addition, Zu Chongzhi is also very proficient in music and rhythm, and also has a very high attainment in literature and research, and is good at playing chess, writing "Shu Wei Ji", is a rare erudite scientist in history.
