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 team that laid the foundations for the team spirit and intensive training that led to future athletic success. 1989 also witnessed the birth of Disco Inferno, the Brown Women's Ultimate team and the relationship between men's and women's teams helped players reformulate playing and training strategies. Sometime around 1996, Brownian Motion reformed, changing from an "old school" team to a "new school" team with championship dreams. By 1998, Brownian Motion had never won a Sectional's championship. However, making its first cross-country trip as a team, Brownian Motion competed at the premier Stanford Invitational Tournament in 1998, finishing an even 3-3,
