The discoverer was Johannes? Kepler. He is an outstanding astronomer, physicist and mathematician in Germany. Regarding the laws of planetary motion, Kepler has always found three laws, namely, orbit, area and period. It was because he discovered these three laws that he won the prize? Sky legislator? The reputation of. He not only achieved such great honor in astronomy, but also made great contributions in other fields such as mathematics and optics.

Johannesburg? Kepler. Born in170s, 58 years old. Kepler studied at the University of Tubingen and worked as a university professor at his alma mater for several years after graduation. He also finished his first book in astronomy. Even now, none of Kepler's ideas written in the book are correct. However, it can still be seen that Kepler's thought is very advanced. So Kepler was also invited to be an assistant to a famous astronomer at that time, and was later invited by the emperor to be a royal mathematician. So until Kepler died, he was a royal mathematician.

Started studying astronomy. Since the death of the man who invited himself to be an astronomer's assistant, and he was his successor, Kepler began to study astronomy. Because his tutor was a very great astronomer, Kepler began to study his tutor's notes. According to these notes, Kepler also wrote a fantasy novel. In the book, he also wrote many things that are available now, such as spacesuits and so on. At that time, Kepler actually had the basic prototype of gravity, but for various reasons such as war, Kepler could not continue his research.

Kepler not only made contributions in astronomy, but also in optics. Before the Renaissance, a man wrote some important optical theories, and then Kepler continued to develop on this basis, telling why people were nearsighted and farsighted, precisely because of the retina.
