Brownian ratchet ratchet will not rotate continuously in one direction but will move randomly back and forth, and therefore will not produce any useful work. The reason is that since the pawl is at the same temperature as the paddle, it will also undergo Brownian motion, "bouncing" up and down. It therefore will intermittently fail by allowing a ratchet tooth to slip backward under the pawl while it is up. Another issue is that when the pawl rests on the sloping face of the tooth, the spring which returns the pawl exerts a sideways force on the tooth which tends to rotate
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
