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. He uses this as a proof of the … Meer weergeven In mathematics, Brownian motion is described by the Wiener process, a continuous-time stochastic process named in honor of Meer weergeven • Brownian bridge: a Brownian motion that is required to "bridge" specified values at specified times • Brownian covariance • Brownian dynamics • Brownian motion of sol particles Meer weergeven • Einstein on Brownian Motion • Discusses history, botany and physics of Brown's original observations, with videos • "Einstein's prediction finally witnessed one century later" : a test to observe the velocity of Brownian motion Meer weergeven Einstein's theory There are two parts to Einstein's theory: the first part consists in the formulation of a diffusion equation for Brownian particles, in which the … Meer weergeven The narrow escape problem is a ubiquitous problem in biology, biophysics and cellular biology which has the following formulation: a Brownian particle (ion, molecule Meer weergeven • Brown, Robert (1828).

This is a discrete-time random process with stationary independent increments. Returning to …
