Kepler Mysterium Cosmographicum

In his 1596 hook Mysterium Cosmographicum, Kepler proposed a solar system that placed the orbits of the six known planets on concentric spheres inscribed within and circumscribed on these five polyhedra arranged concentrically. In the words of Jacob Bronowski All science is the search for unity in hidden likenesses. He states further To us, the analogies by which Kepler listened for the movement of the planets in the music of the spheres are farfetched. Yet are they more so than the wild leap by which Rutherford and Bohr in our own century found a model for the atom in, of all places, the planetary system ...

It has been proposed to call the Mon i2-type cluster a Keplerate corresponding to Kepler s early speculative model of the cosmos and concept of planetary motion, as described in his opus Mysterium Cosmographicum [10]. In accordance with this model, Kepler believed that the distances between the orbits of the planets could be explained if the ratios between the successive orbits were designed to be equivalent to the spheres successively circumscribed around and inscribed within the five Platonic solids. By analogy, the cluster correspondingly shows concentric spherical shells of 132 terminal oxygen and 132 molybdenum atoms while the centers of the 12 [(Mo)°(Mo5) ...
