Brownian ratchet a heat bath in that they undergo random Brownian motion with a mean kinetic energy that is determined by the temperature. The device is imagined as being small enough that the impulse from a single molecular collision can turn the paddle. Although such collisions would tend to turn the rod in either direction with equal probability, the pawl allows the ratchet to rotate in one direction only. The net effect of many such random collisions would seem to be that the ratchet rotates continuously in that direction. The ratchet's motion then can be used to do work on other systems,
Brownian Motion Ultimate Brownian Motion Ultimate Brownian Motion is the men's Ultimate team at Brown University. The team has a long, distinguished history as one of the top college Ultimate teams in the United States. Brownian Motion took home first place at the 2005 Ultimate Players Association College Championship Series in Corvallis, Oregon. Officially founded as a University organization on December 7, 1975, B-Mo (Brownian Motion's nickname) began in an effort to "rise against the challenge of other institutions," as the team's constitution reads. Like most other college Ultimate teams at the time, it consisted mostly of people who enjoyed playing frisbee, rather
