Rotational Brownian motion (astronomy) that the rotation axis of the binary is oriented at angle θ at time "t". The evolution equation for "F" is formula_17 If <Δξ>, "a", ρ and σ are constant in time, this becomes formula_18 where μ = cos θ and τ is the time in units of the relaxation time "t", where formula_19 The solution to this equation states that the expectation value of μ decays with time as formula_20 Hence, "t" is the time constant for the binary's orientation to be randomized by torques from field stars. Rotational Brownian motion was first discussed in the context of binary
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
