Tycho brahe's anecdotes.

tycho brahe is a strange man in the history of astronomy. His observation of the stars was accurate and rigorous at that time, reaching an unprecedented level. The data of its compiled catalog is even close to the limit of the resolution of the naked eye, which is staggering. Tycho's data was used by his disciple, the famous Kepler, which created the famous three laws of planetary motion and made the beginning of modern astronomy. There are two gossip stories about Tycho. One is about his nose. It is said that Tycho is a grumpy man. He once quarreled with another nobleman from Denmark at a dance, which sowed the seeds of tragedy. Because the quarrel broke out again soon, the two decided to solve the problem in a noble way and start a duel. Tycho's swordsmanship is obviously not as good as his opponent's, but he is much luckier than Galois 266 years later. He just had his nose cut off.

There was obviously no cosmetic surgery in Tycho's time, but he did something even more jaw-dropping: he made a fake nose out of metal himself and put it on his face very skillfully. The color of this fake nose is like skin, and it is installed seamlessly! At that time, it was recorded that Tycho carried a small box with glue in it all day, which could stick his nose at any time. In 191, when Tycho's tomb was opened, a large pool of green was found in the center of his skull, indicating that his nose obviously contained copper. As for the specific composition, perhaps only Tycho himself knows. In the 17th year of Yuan Dynasty (128), Guo Shoujing inherited the traditional calendar and compiled a new calendar with reference to the Arabic calendar, which was named "Timing Calendar". Guo Shoujing said in his report to Yuan Shizu that the Chronological Calendar re-measured seven items of astronomical data and reformed five items of astronomical calculation. The length of a tropical year is estimated to be 365. 2425 days in Shoushi Calendar, which is only 26 seconds different from the actual cycle of the earth around the sun, which is the same as the Southern Song Dynasty calendar and the modern Gregorian calendar. The Gregorian calendar was formulated by Pope Gregory XIII in 1582, which was 3 years later than the Chronological Calendar.

Guo Shoujing's astronomical achievements and Tycho, a Danish astronomer 3 years later, complement each other successively. Tang Ruowang, a Jesuit who came to China in the late Ming Dynasty, praised Guo Shoujing as Tycho of China. In fact, Guo Shoujing was three centuries earlier than Tycho, so it should be said that Tycho is the Guo Shoujing of Europe. (Summary of National History, edited by Fan Shuzhi)
