Brownian web Brownian web In probability theory, the Brownian web is an uncountable collection of one-dimensional coalescing Brownian motions, starting from every point in space and time. It arises as the diffusive space-time scaling limit of a collection of coalescing random walks, with one walk starting from each point of the integer lattice Z at each time. What is now known as the Brownian web was first conceived by Arratia in his Ph.D. thesis and a subsequent incomplete and unpublished manuscript. Arratia studied the voter model, an interacting particle system that models the evolution of a population's political opinions. The individuals of
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
