full_question: Dirac derived the relativistic formula for a force named for this man and an alphabetically-earlier physicist using the Lienard-Wiechert potentials in place of the Larmor formula; that force is proportional to the charge squared times the jerk. With a Danish mathematician, this man names an equation relating refractive index to polarizability and inverse density, a special case of the Clausius-Mossotti relation. The classical recoil on an accelerating particle from its own radiation, often called the self-force, is named for this man and Abraham. This man names the set of all rotations and boosts in Minkowski spacetime, as well as a quantity symbolized gamma that is used to calculate the amount of time dilation. For 10 points, name this Dutch namesake of a set of transformations and factors central to special relativity.
