Biography johannes kepler planetary laws of motion

Johannes Kepler was a German astronomer, mathematician and astrologer, who discovered laws of planetary motion. Kepler was a key figure in the Scientific Revolution of the 17th Century — confirming the theories of Copernicus and laying the foundation for Issac Newton to discover the laws of gravity. He also worked on optics, inventing an improved version of the refracting telescope.

It is all the same to me. It may wait a hundred years for its readers, as God has also waited six thousand years for an onlooker. From an early age, he displayed prodigious mathematical talent and a love of astronomy. He studied at the University of Tubingen, where he studied philosophy and theology and also astrology and astronomy.

Kepler's third law of planetary motion

He learned about the geocentric Ptolemaic system and the innovative, yet unproven Copernicus system of planetary motion. Kepler inclined to the Heliocentric view of Copernicus and defended it from both a scientific and religious perspective. In , at the age of 23, he accepted a position in Graz to teach mathematics. Here in Graz, he published his first major work Mysterium Cosmographicum The Cosmographic Mystery, which promoted a Copernicus viewpoint, he later rejected some of the main thesis in his own work, but its brilliant mathematics and clear reasoning helped establish his reputation.

The marriage was often rocky.
