This man extended the Langevin-Nyquist formalism for fluctuations by a method called the  regression hypothesis.
This man extended the Langevin-Nyquist formalism for fluctuations by a method called the  regression hypothesis. He also modified the Debye-Huckel theory of (*) electrolytic dissociation to account for Brownian motion. His namesake reciprocity relations are solutions for a square lattice of spins.  For 10 points— name this 1968 Nobel Laureate in Chemistry for his exact solution to the two-dimensional Ising model.
