Johannes Kepler was a famous German mathematician and astronomer who discovered the ovoid movements of the planets around the sun. The first astronomer to state the fundamental laws of planetary motion, Kepler was also known for his works in geometry, optics and philosophy. His significant achievements have been the discovery of the Kepler’s Star, the ‘Astronomia Nova’ and also the 'Kepler Conjecture'. For being one of the prominent figures in astronomy, a lot of astral elements were named after him such as ‘Kepler’s crater on Mars’, ‘The Kepler Moon crater’ etc. Apart from astronomy, Kepler concentrated on mathematics and the evolution of geometry. He came up with ‘Kepler Triangle’ and the ‘Kepler Problem’, both of which, published in three parts, studied various aspects of geometric progression, characterized by the ‘Pythagorean Theorem’ and the ‘Golden Ratio’. As a part time amusement, he even studied astrology and published a few works on the subject such as ‘De Fundamentis Astrologiae’ and ‘Dissertatio cum Nuncio Siderio’. He worked for Tycho Brahe, a Danish nobleman and even served as an advisor to Emperor Rudolph II during his lifetime. Scroll down to learn more about this interesting personality.
