On this day 479 years ago, December 14th, 1546 (November 22nd, 1546 in the lunar calendar), Tycho Brahe, the ancestor of modern astronomy, was born. Tycho Brahe, the ancestor of modern astronomy, had an earth-shattering event in the world in 1572, that is, Tycho, a 26-year-old Danish astronomer, discovered a new star in the constellation Sendai after accurate observation on December 11th of this year. He wrote a paper on the title of "Rising Star" and published it. This paper is better than a giant bomb. It shakes Aristotle's doctrine of celestial immutability, which people have always adhered to. Tycho was born on 14 December 1546 in a noble family in Scania, Denmark. As a youth, he first studied philosophy and rhetoric at the University of Copenhagen, and later studied law at the University of Leipzig. But his favorite thing was astronomy. He studied Ptolemy's Almagest with great interest and perseverance, and devised a massive mound observation program. In order to complete his celestial observation plan, Tycho set up the famous Forborg Astronomical Observatory on Vern Island with all the grant granted to him by the King of Denmark. This observatory is large in scale and complete in instruments. The instruments were all made by Tycho himself and were made of wood, iron and copper. Among them, the largest quadrant instrument with high precision is called Tycho quadrant instrument. Tycho has been working in Fern Island for 20 years, obtained a large amount of astronomical data, discovered many new astronomical phenomena, made great contributions to astronomy, and was praised by later generations as "the ancestor of modern astronomy". In 1599 Tycho settled in Prague and transported instruments from the island of Vern to Prague. Tycho met with Kepler in 1600, and they started a new work plan together. Unfortunately, Tycho died of illness in 1601, and his unfinished business was completed by Kepler. Kepler did not live up to his expectations. He used the rich astronomical data accumulated by Tycho to further study, and finally discovered the "Three Laws of Planetary Motion" and completed the compilation of Rudolph's star catalog. Tycho Brahe The Danish aristocrat Tycho Brahe, the ancestor of modern astronomy, has always been a controversial figure. British media recently revealed that Tycho had his nose cut off by his opponent in a duel, and finally had to put on a fake nose. Three hundred years after his death, when the body was exhumed, the nose was actually intact! Tycho Brahe was born on December 14, 1546, to a noble family in Kiudestep, Scania, Denmark. At that time, there were no astronomical telescopes. In 1572, 26-year-old Tycho discovered that a star brighter than Venus exploded. Later generations named this star "Tycho Brahe Supernova". Tycho's discovery established his position as the "ancestor of modern astronomy". Tycho's contributions to astronomy are well known, but what is not known is that he was a "aggressive man" and had his nose cut off for his aggressiveness. In 1566, at the age of 20, Tycho attended the University of Rostock, Germany. After a drunkenness, he had an argument with his classmates, and two drunk young people decided to duel the outcome. Because it was already dark and dizzy after drinking, the two duelists couldn't see each other clearly. Amid a cry of exclamation, Tycho's nose was accidentally cut off by the other party. To cover up the defects of his body, Tycho designed a metal nose for himself, composed of gold and silver. Since then, Tycho has a nickname-"Golden Nose". In 1901, 300 years after Tycho's death, his body was exhumed by archaeologists. At that time, the body had already decayed, but the "golden nose" was intact, but it had turned green due to oxidation. Some historians suspect that Tycho's false nose is not made of gold and silver, but of copper. It is also suspected that Tycho's tomb was once patronized by grave robbers, and the "golden nose" was replaced by a "copper nose". Quirk: Love to see the drunken moose. When studying Tycho's life, historians found that this great scientist has another quirk, that is, he loves to see the drunken moose look. According to the documents, Tycho kept a moose in his castle. Unfortunately, after a drunken bout, the moose fell down the stairs and died. Without the moose, Tycho's life was much lonelier. In his later years, Tycho worked in Prague and established the new observatory. Tycho met Kepler in 1600 and invited the latter as his assistant. Tycho died in 1601 and Kepler succeeded him. Tycho was an outstanding observer and founder of modern astronomy, but his view of the universe was wrong. Tycho believes that all planets orbit the sun, and the sun leads the planets around the earth. His theory is ultimately geocentric. Tycho Brahe (1546-1601) Tycho contributed a lot to the study of astronomy in his life. Now on the moon, there is a crater named after Tycho.
