Johannes Kepler
Biography
Johannes Kepler is now chiefly remembered for discovering the three laws of planetary motion that bear his name published in 1609 and 1619). He also did important work in optics (1604, 1611), discovered two new regular polyhedra (1619), gave the first mathematical treatment of close packing of equal spheres (leading to an explanation of the shape of the cells of a honeycomb, 1611), gave the first proof of how logarithms worked (1624), and devised a method of finding the volumes of solids of revolution that (with hindsight!) can be seen as contributing to the development of calculus (1615, 1616). Moreover, he calculated the most exact astronomical tables hitherto known, whose continued accuracy did much to establish the truth of heliocentric astronomy (Rudolphine Tables, Ulm, 1627).A large quantity of Kepler's correspondence survives. Many of his letters are almost the equivalent of a scientific paper (there were as yet no scientific journals), and correspondents seem to have kept them because they were interesting. In consequence, we know rathe

Johannes Kepler (;[2]German:[joˈhanəsˈkɛplɐ,-nɛs-]ⓘ;[3][4] 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music.[5] He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copern Johannes Kepler was born on December 27, 1571 in Weil der Stadt, a little town near Stuttgart in Württemberg in southwestern Germany. Unlike his father Heinrich, who was a soldier and mercenary, his mother Katharina was able to foster Kepler’s intellectual interests. He was educated in Swabia; firstly, at the schools Leonberg (1576), Adelberg (1584) and Maulbronn (1586); later, thanks to support for a place in the famous Tübinger Stift, at the University of Tübingen. Here, Kepler became Magister Artium (1591) before he began his studies in the Theological Faculty. At Tübingen, where he received a solid education in languages and in science, he met Michael Maestlin, who introduced him to the new world system of Copernicus (see Mysterium Cosmographicum, trans. Duncan, p. 63, and KGW 20.1, VI, pp. 144–180). Before concluding his theology studies at Tübingen, in March/April 1594 Kepler accepted an offer to teach mathematics as the successor to Georg Stadius at the Protestant school in Graz (in Styria, Au
