9) Can you describe Brownian Motion ?
This is the random motion of particles in a fluid resulting from their collision with the fast moving atoms in the fluid.
This is a continuous-time random (stochastic) process and it is a limit of both simpler and more complicated random processes (random walk and Donsker theorem)
Brownian motion is described by the wiener process
