Norbert Wiener applied the Lebesgue integral to measure this process, which Bachelier used to describe changes in the price of stock.
Norbert Wiener applied the Lebesgue integral to measure this process, which Bachelier used to describe changes in the price of stock. Perrin's study of it helped determine Avogadro's number (*), and demonstrated the existence of atoms. Einstein derived the diffusion constant in his paper about this phenomenon, which was discovered when its namesake observed pollen grains floating in water. FTP, name this stochastic process, the random movement of particles in a fluid.
