Along with a Danish mathematician, he lends his name to an equation relating index of refraction to density, also known as the Clausius-Mossotti equation.
This person's namesake gas consists of a fixed array of spherical scatterers, with a single particle elastically scattering between them. When the effect of radiative reaction force is included, the equation of motion for a nonrelativistic charged particle is named for him and Abraham. Along with a Danish mathematician, he lends his name to an equation relating index of refraction to density, also known as the Clausius-Mossotti equation. His namesake factor equals one over the square root of one minus beta squared, and is symbolized by a lowercase gamma. FTP, name this co-discoverer of the Zeeman effect, whose namesake transformation shows how to transform spacetime coordinates to a moving reference frame in special relativity.
