Brownian motion apart once the particle is in motion. Also, there would be a distribution of different possible Δ"V"s instead of always just one in a realistic situation. The diffusion equation yields an approximation of the time evolution of the probability density function associated to the position of the particle going under a Brownian movement under the physical definition. The approximation is valid on short timescales. The time evolution of the position of the Brownian particle itself is best described using Langevin equation, an equation which involves a random force field representing the effect of the thermal fluctuations of the solvent on
Brownian Motion Ultimate instead of the usual two. When Tufts soundly defeated Brown in the finals at regionals, Brown missed nationals for the first time since 1997. The bright spot for Brownian Motion was the extremely talented freshman class, including Alexander Bowman, Dan MacArthur, Neale Mahoney, Ben Sprung, Paul Vandenberg, and future Callahan Award winner Joshua "Zip" Ziperstein. Entering the 2003 season, Brown was looking to be one of the top programs in college Ultimate, despite failing to qualify for Nationals the previous year. With a relatively young team, Brown won regionals without losing a game, beating a talented UMass squad 17-15 in
