Bücher von Johannes Kepler

Johannes Kepler (1571-1630), one of the founders of modern astronomy, revolutionized the Copernican heliocentric theory of the universe with his three laws of motion: that the planets move not in circular but elliptical orbits, that their speed is the greatest when nearest the sun, and that the sun and planets form an integrated system. Kepler is the author of Epitome of Copernican Astronomy, Harmony of the Worlds, and On the Six-Cornered Snowflake.
