A device developed by Cohen and Moerner called the ABEL trap counteracts this phenomenon by means of electrokinetic feedback. A generalization of this process to situations of non-zero fluid velocity was developed by Kraichnan to investigate the passive scalars problem. It is possible to compute the Boltzmann constant from this process by multiplying the mass by the diffusivity and dividing by the product of temperature and relaxation time. This Wiener (*) process is described by an equation that models the evolution of particle position distributions under the influence of drag and stochastic noise; that special form of the Fokker-Planck equation is the Smoluchowski equation. The mean square displacement of this process is given by twice the diffusion constant times the elapsed time. For 10 points, identify this process first elucidated in 1905 by Einstein, the random walk of a particle in a viscous fluid.
