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 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
