What Is Brownian Motion?. Explaining Wiener Process - Medium
It is the random movement of particles in a fluid. This indeterministic movement is due to the collision of the particles with the molecules in the fluid.
The Wiener process is a stochastic process that provides a pure mathematical definition of the physical phenomenon of Brownian motion.
