![math.ucsd.edu Ex. 8.1.4. Let us begin by observing some general consequences of the independence of the 2/3 213 crements of the Brownian motion. Suppose that Z is a random variable that depends only on the Brownian motion at several times t1, t,.,tn, all at most t. Then Z is independent of B(t u) -B(t) for u > 0, so EZ-B(t)], the second equality following from the independent increments and the third from the fact that E[B(t + u)] = E[B(t)) = 0. Likewise, with Z as before Finally, the same reasoning together with the fact that EB for all0 shows that](http://img.homeworklib.com/questions/4504b9a0-73a7-11eb-919a-9f4c025a3acc.png?x-oss-process=image/resize,w_560)

Einstein's original approach to Brownian motion had a different starting point, focusing on position differences at each time step x(t + Δt)-x(t) + E(t) where £(t) is a random displacement chosen from some distribution W(E).
