This physicist co-names a theory that introduces a scale parameter B to eliminate the divergence of the classical electron's self-energy. He also names a special relativistic property for solids that naively requires an infinite speed of sound and cannot be maintained while rotating.  An empirical exponent between five and twelve named for this man represents a repulsive term and appears in a formula for the lattice energy of a ionic crystal. This man also conames an application of Hess's law used to approximate ionic lattice energies.  FTP, identify this first German namesake of an approximation which assumes that nuclear motion is much slower than electronic motion, along with Oppenheimer.
