Who is Zu Chongzhi's son?

Zu Xuan is the son of Zu Chongzhi, an outstanding mathematician in the Northern and Southern Dynasties. Date of birth and death is unknown. Influenced by his family, especially his father, he loved science since childhood and was particularly interested in mathematics. In 462, Zu Chongzhi compiled Da Li Ming according to three suggestions made by Zuxuan. According to scholars' textual research, some entries in Seal Script were written by Zu Xuan. Zu Xuan devoted himself to reading all his life, and made many jokes because he thought about problems while walking. The principle of ancestral graves is a method to calculate the volume of spheres, and it is the most representative discovery of Zu Xuan's life. He put forward a principle: "If the potential is the same, the products will not be different." Here, "force" refers to the area of the horizontal section, and "potential" refers to the height. If the horizontal cross-sectional areas of two geometric bodies with the same height are equal, the volumes of the two geometric bodies are equal. This principle is easy to understand. Put a stack of books or papers on a horizontal desktop, and then push it by hand to change its shape. At this time, the height and area of each page have not changed, so the volume of this stack of books or papers is equal to the volume before deformation. Zu Xuan not only explicitly put forward this principle for the first time, but also successfully applied it to the calculation of ball volume. We call this principle "the ancestral grave principle". Cavalieri's principle, known in western literature, was independently put forward by Italian mathematician cavalieri (B. cavalieri, 1598- 1647) in 1647, which had an important influence on the establishment of calculus. According to the cuboid volume formula and the principle of ancestor pestle, the volume of cylinder, cone, platform, sphere and so on is calculated. Available. Zu Xuan, whose real name is Jing Shuo, is the son of Zu Chongzhi, a mathematician and scientist in the Southern Dynasties. After Zu Chongzhi's death, he wrote to Liang Chaotian three years (AD 504), eight years and nine years, suggesting that Da Liming, who adopted his father, finally realized his father's last wish. Zu Xuan's main job is to repair and edit his father's mathematical work "Composition". He developed his father's research results, and skillfully proved the volume formula of the ball by using the principle of ancestral pestle and the opening technique created by himself. He found that this formula was at least 65,438 years earlier than the Italian mathematician Bonaventura Envalieri (A.D. 1589- 16438). There are many other scientific discoveries made by Zu Xuan, such as affirming that Polaris is not really at the north celestial pole, but is off by more than one degree. Calculating these results is inseparable from his rich mathematical knowledge. Zu Chongzhi's son, Zu Xuanzhi, was a great mathematician at the time of Qi and Liang Dynasties in the Southern Dynasties, and was a magistrate. Because of his family background, he also studied mathematics since childhood. Zu Xuan is so ingenious, so absorbed in reading and thinking that he can't hear the thunder. On one occasion, he thought about math problems while walking. Walking, I met Xu Mian, a servant coming from the opposite side. "Servant Shooter" is a very high official, and Xu Mian is an important figure in the imperial court, but he was beaten badly by this teenager and could not help crying. Zuxuan just woke up at this moment. The Liang Dynasty fought against the Northern Wei Dynasty and failed. Zuxuan was detained by Weifang and arranged to stay in a hotel, which was very favorable. Zu Xuan met an astronomy enthusiast Xin, and they often discussed astronomy and mathematics together, which was very speculative. Zuxuan taught his knowledge to New Du Fang without reservation, which made him make great progress. Zu Xuan is also very successful in science. It was because of his suggestion that Da Liming was adopted by Liang Dynasty. Some records say that seal script has his research results. He first proposed a formula for calculating the volume of a sphere, which was earlier than that in Europe 1000 years. Also developed a variety of precision observation instruments, such as heliostats and leaky pots. Zu Hao, the son of Zu Xuan, passed on the family line and later became a mathematician.
