Johannes Kepler graduated from the Faculty of Arts at the University of Tuebingen at age twenty, going to matriculate in to the Theological Faculty. It was below that Kepler discovered and started to be an adherent of the heliocentric theory of planetary action, first produced by the Dutch astronomer Nicolaus Copernicus.
In 1594, Kepler left Tuebingen for the University of Graz to become professor of astronomy. It was below that Kepler understood that figures of the sort shown here decide a definite resolved ratio between your sizes of the two circles, presented the triangle possesses all sides equivalent, and
