subject = Physics title = Tycho Brahe's Contributions to Physics papers = TYCHO BRAHE Tycho Brahe was born on December 14 th, 1546 in a town called Knudstrup in Scania, Denmark. His early years were filled with pain, as he was kidnapped by his uncle and raised in his castle in Tostrup, Scania. His education was backed by his uncle, and he went to the University of Copenhagen to study law from 1559 - 1562. It was during this time that Brahe developed a love for astronomy. He saw a solar eclipse of the Sun which was predicted for August 21 st 1560, and he found it fascinating how a prediction of that nature could be made. He also developed small globes with the help of some of his instructors at Copenhagen.
In 1562, Brahe was sent to the University of Leipzig where he studied until 1565. During this period, he made his first astronomical observation. He saw an overlapping of Jupiter and Saturn, and saw that the almanacs and ephemerides of the time were inaccurate. Between 1565 and 1570, he traveled Europe, studying at Wittenberg, Rostock, Basel, and Augsburg.
During this time he gathered astronomical and mathematical instruments, including a large quadrant. In 1571, he settled in Scania after inheriting the land of his father and uncle and built a small observatory. Here, he discovered a star, one which had not been seen, that was brighter than Venus. This supernova in the constellation Cassiopeia shocked the scientific community because it suggested that the universe was not in fact perfect and unchanging, as it was believed to be at the time.
With the discovery of this new star, Brahe dedicated himself to astronomy. Frederick II, king of Denmark and Norway, provided Tycho with funds to construct and equip an astronomical observatory on the island of Hven in 1576. Brahe named this observatory Uraniborg. For 20 years, the observatory was the center for astronomical study and discovery in northern Europe. In 1577 he proved that the orbit of the comet of 1577 did lay beyond the moon. He also charted accurate positions for more than 777 fixed stars.
He also proposed a modified Copernican system which suggested that the planets revolved around the Sun which in turn moved around the Earth, which was stationary. Frederick II died in 1588 and his son Christian IV took over as king. Brahe lost most of his income as a result. Tycho left Hven and his observatory in 1597. He was offered a grant to Bohemia from the Holy Roman Emperor Rudolf II, who gave him a pension of 3000 ducats and an estate near Prague. He started building a new observatory, but died in 1601 before it could be completed.
Brahe? s work was indeed significant. His data that he had accumulated during his lifetime was extremely accurate, and it allowed his assistant Johannes Kepler to formulate his three laws of planetary motion. He also laid the ground work for Sir Isaac Newton.
Much of what we know about astronomy is thanks to Tycho Brahe. His last words in Prague were, Ne frustrate vitesse video, or, May I not seemed to have lived in vain. He indeed did not.
