Johannes_Kepler

Johannes Kepler Johannes Kepler Johannes Kepler was born on December 27, 1571, a premature child. He was born in Weil, in Swabia, a wine region in Southwest Germany not far from France. Kepler waent to the University of Tuebingen, a Protestant institution, where he studied mainly theology and philosophy, but also mathematics and astronomy. After Kepler graduated from Tuebingen, he was offered a professorship of astronomy in faraway Graz, Styria where he went in 1954. One of the duties of this Professorship was to make astrological predictions. While lecturing to his math class in Graz, contemplating some geometric figure involving Concentric Circles and triangles on the backboard, Kepler suddenly realized that figures of the type shown here determine a definite fixed ratio between the sizes of the two circles, provided the triangle has all sides equal, and a different ratio between the sizes will occur for a square between the two cirtcles, another for a regular pentagon. He really believed in the Copernicah System, so he saw the planetary orbits as six concentric circles. He felt the universe would somehow show mathematical beauty of symmetry. He suggested that the orbits might be arranged so that regular polygons would kepler, just, between, tycho, sun, planets, orbits, force, work, substantial, two, planet, one, distance, circles, universe, tetrahedron, system, spheres, soul, six, regular, own, outer, orbit, kepler’s, graz, concentric, around, another, year, word, tycho’s, tuebingen, took
