BEN DENISTON • If Kepler knew of Uranus and Neptune

Extending Kepler's investigation of the planetary harmonies, Ben uses modern data to reveal the changing nature of the harmonies, which Gauss had studied in the harmonic perturbations of the asteroids. The subtle modulation of planetary motions over time indicate the embedded harmonies in the universe at large, as well as their implications for life on earth itself—as shown in the Milankovitch cycles governing glaciation.
