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 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
