Harmonices Mundi

"The music of the spheres."

Johannes Kepler was convinced that the universe was built according to musical harmonies. In this book, amidst mystical speculation, he derives the Third Law of Planetary Motion, which links the time a planet takes to orbit the sun with its distance from it.

It is a fascinating glimpse into the mind of a scientist bridging the gap between medieval mysticism and modern astronomy. Kepler listens to the song of the planets and finds the mathematical rhythm of the solar system.
