| <img src="/kepler/images/kepler.png" id="kepler_pic" /><strong>Johannes |
| Kepler</strong> (German: <span |
| title="Representation in the International Phonetic Alphabet (IPA)">[ˈkʰɛplɐ]</span>; |
| December 27, 1571 – November 15, 1630) was a German |
| mathematician, astronomer and astrologer. A key figure in |
| the 17th century scientific revolution, he is best known for |
| his eponymous laws of planetary motion, codified by later |
| astronomers, based on his works <em>Astronomia nova</em>, <em>Harmonices |
| Mundi</em>, and <em>Epitome of Copernican Astronomy</em>. |
| These works also provided one of the foundations for Isaac |
| Newton's theory of universal gravitation. |
| </p> |
| <p>During his career, Kepler was a mathematics teacher at a |
| seminary school in Graz, Austria, where he became an |
| associate of Prince Hans Ulrich von Eggenberg. Later he |
| became an assistant to astronomer Tycho Brahe, and |
| eventually the imperial mathematician to Emperor Rudolf II |
| and his two successors Matthias and Ferdinand II. He was |
| also a mathematics teacher in Linz, Austria, and an adviser |
| to General Wallenstein. Additionally, he did fundamental |
| work in the field of optics, invented an improved version of |
| the refracting telescope (the Keplerian Telescope), and |
| mentioned the telescopic discoveries of his contemporary |
| Galileo Galilei.</p> |
