Rotational Brownian motion Rotational Brownian motion Rotational Brownian motion is the random change in the orientation of a polar molecule due to collisions with other molecules. It is an important element of theories of dielectric materials. The polarization of a dielectric material is a competition between torques due to the imposed electric field, which tend to align the molecules, and collisions, which tend to destroy the alignment. The theory of rotational Brownian motion allows one to calculate the net result of these two competing effects, and to predict how the permittivity of a dielectric material depends on the strength and frequency of the
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,
