Bibliography : see CGMP p1484 Vol4, Metal91A p37 (see plate below). Johannes Kepler (December 27, 1571 – November 15, 1630), a key figure in the scientific revolution, was a German mathematician, astronomer, astrologer, and an early writer of science fiction stories. He is best known for his laws of planetary motion, based on his works Astronomia nova, Harmonice Mundi and the textbook Epitome of Copernican Astronomy. Through his career Kepler was a mathematics teacher at a Graz seminary school (later the University of Graz, Austria), an assistant to Tycho Brahe, court mathematician to Emperor Rudolf II, mathematics teacher in Linz, Austria, and court astrologer to General Wallenstein. He also did fundamental work in the field of optics and helped to legitimize the telescopic discoveries of his contemporary Galileo Galilei. He is sometimes referred to as "the first theoretical astrophysicist", although Carl Sagan also referred to him as the last scientific astrologer. Harmonice Mundi (Latin: The Harmony of the World, 1619) is a book by Johannes Kepler. It attempts to explain proportions and geometry in the planetary motions and the astrological aspects by relating them to harmonics (musical scales and intervals) [1] (also see Musica universalis). Kepler's The Harmony of the World is divided into five long chapters: the first is on regular polygons; the second is on the congruence of figures; the third is on the origin of harmonic proportions; the fourth on harmonic configurations in astrology; and the fifth on the harmony of the motions of the heavens. According to Kepler, each planet produces musical tones during its revolution about the Sun, and the pitch of the tones varies with the angular velocities of those planets as measured from the Sun. Some planets "sing" relatively constant tones: for example, the Earth only varies a semitone (a ratio of 16:15), from mi to fa, between aphelion and perihelion, and Venus only varies by a tiny 25:24 interval. Kepler explains the reason for the Earth's small harmonic range: The Earth sings Mi, Fa, Mi: you many infer even from the syllables that in this our home misery and famine obtain. At very rare intervals all of the planets would sing together in 'perfect concord': Kepler proposed that this may have happened only once in history, perhaps at the time of creation. In his previous book Astronomia nova, Kepler had put forward the first two laws of planetary motion. The third law, namely the proportionality of the cube of the average distance of a planet from the Sun and the square of the length of its year, was set out in Chapter 5 of this book, immediately after a long digression on astrology.
