            <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>
