Jean Perrin confirmed the atomic nature of matter and derived Avogadro's number in his studies of this process.
This process powers the perpetual motion machine known as Feynman's ratchet. Langevin derived his namesake equation to model this process. This process is also known as the Weiner process. Jean Perrin confirmed the atomic nature of matter and derived Avogadro's number in his studies of this process. Those studies also verified the stochastic model of this process described in one of Einstein's Annus Mirabilis papers. It was discovered when its namesake observed (*) pollen grains suspended in water. For 10 points, name this random movement of particles suspended in a fluid.
