Brownian motion, or pedesis (from Ancient Greek: πήδησις /pɛ̌ːdɛːsis/ "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas). This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to … Meer weergeven The Roman philosopher-poet Lucretius' scientific poem "On the Nature of Things" (c. 60 BC) has a remarkable description of the motion of dust particles in verses 113–140 from Book II.

Web3a Simple walks embedded into Brownian motion The simple (symmetric, one-dimensional) random walk is (by definition) the sequence of random variables Sn = X1 + ··· + Xn where X1,X2,... are independent random signs, P Xk = −1 = 0.5 = P Xk = +1. This is a discrete-time random process with stationary independent increments.
