This process follows the Langevin equation, which can be evaluated using the Fokker-Planck equation.
This process follows the Langevin equation, which can be evaluated using the Fokker-Planck equation. A thought experiment proposed by Marian Smoluchowski could extract energy from this process, but Richard Feynman shot down that idea by noting that this process would also apply to the pawl. This process roughly approaches the (*) Wiener process, like random walks, and Einstein's model of this process can be used to derive Avogadro's number. The namesake of a hypothetical ratchet is, for ten points, what phenomenon in which particles in a fluid move randomly, named after the Scottish biologist who first observed it with grains of pollen suspended in water?
