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 players, Brown lost in the quarterfinals of every major tournament in the Spring, including Nationals. This was also the first time in four years that Brown lost Regionals as both Harper Alexander and Moses Rifkin were injured. After the disappointing 2001, 2002 was even worse for Brownian Motion. Having lost Callahan runner-up Moses Rifkin, Brown was a young class of talented players. The team began to play well in the Spring season, losing in the semis at the Stanford Invitational and winning sectionals. However, after a roster submission fiasco in the Northeast, the region had only one bid to Nationals
