Kepler's Harmony of the World

Kepler's Harmony of the World is a work where Johannes Kepler explored the idea that the movements of planets follow specific mathematical ratios, akin to musical harmony. He believed that the distances and orbits of planets are related through simple fractional relationships, creating an "music" of the spheres. Kepler sought to understand the universe's order by showing that celestial motions are governed by harmonious proportions, which reflect a cosmic unity. This work bridged astronomy and music theory, illustrating that the cosmos operates through precise, underlying patterns that can be expressed mathematically.
