Brownian Motion Panel.png

A Procedure File (BM_Simulator.ipf) for simulating a random walk and modeling Brownian Motion. This procedure creates a series of displacements generated after a "particle" experiences a series of random molecular collisions. Each collision moves the particle a distance determined by its mean free path setting. After a defined number of collisions, the particle is at a new, random location and the distance between its starting location and final location is termed a "displacement". In the laboratory setting, this is equivalent to the displacement a particle undergoes in between two consecutive frames during imaging with a CCD camera. A series of these random displacements is then used to estimate Brownian Motion for a particle in 2-D space.

Compiling the procedure places a Menu item under Macros.
