Rotational Brownian motion (astronomy) Rotational Brownian motion (astronomy) In astronomy, rotational Brownian motion is the random walk in orientation of a binary star's orbital plane, induced by gravitational perturbations from passing stars. Consider a binary that consists of two massive objects (stars, black holes etc.) and that is embedded in a stellar system containing a large number of stars. Let formula_1 and formula_2 be the masses of the two components of the binary whose total mass is formula_3. A field star that approaches the binary with impact parameter formula_4 and velocity formula_5 passes a distance formula_6 from the binary, where formula_7 the latter expression
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
