Rotational Brownian motion (astronomy) supermassive black holes at the centers of galaxies. Perturbations from passing stars can alter the orbital plane of such a binary, which in turn alters the direction of the spin axis of the single black hole that forms when the two coalesce. Rotational Brownian motion is often observed in N-body simulations of galaxies containing binary black holes. The massive binary sinks to the center of the galaxy via dynamical friction where it interacts with passing stars. The same gravitational perturbations that induce a random walk in the orientation of the binary, also cause the binary to shrink, via the gravitational
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,
