During the summer vacation, I read a book called Biography of Mathematicians, which tells the stories of many famous mathematicians, such as Pythagoras, Archimedes and Gauss ... Among them, I am most interested in the story about Zu Chongzhi.

Zu Chongzhi was a great scientist in the Southern and Northern Dynasties. He got a very accurate result in the calculation of pi. This article is about Zu Chongzhi's Da Li Ming, which was compiled after a long time. He wrote to the emperor asking for its promulgation and implementation. The emperor ordered his favorite Dai Faxing, who was in charge of the astronomical calendar, to examine it. However, Dai Faxing is conservative and a defender of decadent forces. He is strongly opposed to the new calendar. In the face of Dai Faxing's difficulties and attacks, Zu Chongzhi was unmoved and argued with him endlessly. In the end, Daming Calendar was not passed, and it was promulgated and implemented in 10 after Zu Chongzhi's death.

After reading this story, I admire Zu Chongzhi's indomitable spirit. It is because of this spirit that he can persist. Yes, any success is inseparable from the word "persistence". I can't help thinking of many people, including cultural celebrities, patriotic soldiers and classmates around me.

Reading Biography of Mathematicians makes me like mathematics better, and it also makes me understand a lot of truth.
