We simulate the random motion of 200 particles in a 50 by 50 square in which a particle bounces off the two vertical and top walls and condenses on the bottom wall. Animations are produced and data is offered for modeling with a differential equation. Consider the random motion of 200 particles in a 50 by 50 square with vertices (0,0), (0,50), (50,50), (0,50) in a plane. At each iteration, n = 0, 1, 2,. . . each particle moves 1 unit in one direction only, due north, due east, due south, or due …
