Johannes Kepler was a famous German astronomer, mathematician, and astrologer. His most famous discovery was the three major laws of planetary motion. These laws are now known as Kepler’s law of planetary motion. He is a major key figure in the Scientific Revolution. Born in 1571, in Germany, Johannes Kepler developed a love for astronomy at an early age. He attended what is now the University of Tubingen. “It was expected that boys who graduated from these schools would go on to become schoolteachers, ministers, or state functionaries. Kepler had planned to become a theologian” (Westman 2). It is obvious that Kepler broke this cliché when he realized he would become an astrologer. Kepler had many works, including books. One of Kepler’s first pieces of work was the Mysterium Cosmographicum, which was an astronomy book. After writing this book, “he immediately adopted Gilbert’s theory that the Earth is a magnet” (Westman 3). Kepler also had two other books that he had written. His book Stereometrica Doliorum formed the basis of integral calculus. When Kepler wrote his book …show more content…
Kepler worked as an assisted to Brahe, “who appointed him to understand the orbit of Mars; which was a highly difficult task” (Redd 2). After Brahe’s death, Kepler used his data to help develop the understanding that the orbits of the planets were ellipses to create his Three Mathematical Laws of Planetary Motion that describe the motion of planets in the Solar System. The first law is Planets move in ellipses with the Sun at one focus. Kepler’s second law is the radius vector describes equal areas in equal times. The Third Law is squares of the periodic times are to each other as the cubes of the mean distances. If it was not for Brache appointing Kepler to be his assistant, Kepler would have never discovered the three laws of planetary
