Web8 okt. 2024 · It is the Brownian motion of all particles in a sample which, over time, causes diffusion. What is the history of Brownian motion? Brownian motion is faster for smaller particles, so they can more easily redistribute themselves as the colloid volume decreases. Larger particles cannot move away so quickly and accumulate at the surface-air interface. Web5 jun. 2012 · Definition 2.1Wt = Wt (ω) is a one-dimensional Brownian motion with respect to {ℱ t } and the probability measure ℙ, started at 0, if. (1) Wt is ℱ t measurable for each t ≥ 0. (2) W0 = 0, a.s. (3) Wt − Ws is a normal random variable with mean 0 and variance t − s whenever s < t. (4) Wt − Ws is independent of ℱ s whenever s < t.
