A parameter named for this man approximately the cube root of the number density times the sound speed, and gives the maximum oscillation frequency for phonons, which also underpin this his model of heat capacity. He has a namesake that describes the attenuation of scattering in the Mossbauer Effect, named for him and Waller. Another parameter named for this man is equal in cgs to the square root of the kinetic temperature over the charge squared times the number density. For 10 points, name this physicist with a namesake screening length in plasmas and colloids, and for a theory of electrolyte activity that uses that length scale, devised with Hückel.
