Johannes Kepler is a famous mathematician, astronomer, and astrologer of the Scientific Revolution during the seventeenth century. Kepler has made some very important contribution to the fields of astronomy and mathematics. Without him we might not have made some discoveries until much later. He is one of the most important scientists of the Scientific Revolution. Johannes Kepler made some important contributions to astronomy and had some incredible works and accomplishments all due to his early developed love for science.
To begin, the early life of Johannes Kepler plays a big role in his development to love science. Kepler was born on December 27, 1571 in Weil der Stadt, Württemberg in Germany. He had two brothers and one sister. His mother was Katharina Guldenmann and his father was Heinrich Kepler, who is believed to have died in the Eighty Years’ War. His mother was an innkeeper's daughter, was a healer and herbalist, and she was tried for witchcraft. Kepler was born prematurely and so as a child he was very sickly. When he was young he got chicken pox and that gave him weak vision and crippled hands. On top of this his family was very poor. He was introduced to astronomy early and developed a love for it. He had observed a few astronomical events at an early age, which surely contributed to his love for it. He naturally understood mathematics very well starting at a young age and impressed many people with his mathematical abilities. For example, “he often impressed travelers at his grandfather's inn with his phenomenal mathematical faculty” (Johannes kepler: Early Years, n.d.). His intelligence earned him a scholarship to the University of Tübingen. There he studied theology and philosophy and was introduced to the ideas of Copernicus. In school, he was introduced to the Ptolemaic system and the Copernican system of planetary motion. He strongly believed and defended heliocentrism. He also became the chancellor of Tübingen in 1590. Kepler wanted to be a minister but instead took a job as a
mathematics and astronomy teacher at a Protestant school in Graz at the age of twenty-three. All these things are what made him one of the most influential and important scientist/mathematician in the Scientific Revolution.
In addition, Kepler has made many contributions to the scientific field. One of the most popular discoveries Kepler made was the elliptical orbit of the planets around the sun. This discovery is part of the three laws of planetary orbit. The first law states, “The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus” (Kepler’s Three Laws, n.d.). The second law states that an imaginary line connected from the center of the sun to the center of the planet will sweep out in equal areas in equal amounts of time. The third law states that the ratio of the squares of the periods of two planets is equal to the ratio of the cubes of their distances from the sun. He also...
