John Kepler: Planetary MotionWhen you first think about astronomy, the first thing that comes to mind might be planetary stars. It's always a fascinating thing to learn about the stars, but when learning you should always start somewhere. The search for a person who will always be remembered is that of Johannes Kepler. He is not only the founder of contemporary astronomy, but also an extraordinary mathematician. He was the first to enlighten us on the theory of planetary motion. His three laws of planetary motion were the basis of Isaac Newton's theory of universal gravitation. One of his books was the foundation of integral calculus and advanced geometry. His research had a huge influence on all kinds of things we have today. He is such an important part of scientific history that NASA named a mission after him, involving telescopes searching for habitable planets outside our solar system. Kepler was born on December 27, 1571 in the first imperial city of Weil der Stadt, Germany. His father was Heinrich Kepler, a mercenary (Caspar 29). His mother, Katharina Guldenmann, was the daughter of an innkeeper and was tried for witchcraft because she practiced healing and herbalism (Connor 13). When he was at school, he was the happiest. School allowed him to nourish his mind in a way he couldn't do at home. He first attended a German school, but later attended a Latin school created to educate the new generation of clergy. After nearly completing elementary school, his parents moved, forcing him to work instead of learn. His first love of astrology probably came from his mother, who took the young Kepler to see a comet. Even in... middle of the paper... safe zone”. This would never have been possible without the extraordinary discovery of Johannes Kepler. Works Cited Borucki, W.J. "Kepler's History." History of Kepler. NASA, May 22, 2010. Web. March 13, 2014.
