The Bohr-Rutherford planetary model [1] is still the general public’s favourite image of the mystery of the atom because of its simplicity and “visualizability”. For students of physics and chemistry it represents a sort of inevitable rite of passage on the path towards orbitals and quantum mechanics. As an educational tool, it allows the soft introduction of the quantum of action h, by its app...
