John Weiss's research focus on the dynamics of Saturn's rings at the scale of individual 1-meter ring particles and how collective behaviors between the particles lead to structures forming within the rings or evolution of the ring. He also is interested in the interaction between rings and the small moons that orbit in or near them ("moonlets") as well as a variety of small (but amusing) physics problems. In addition, he likes to delve into the history of science and the experiments and reasoning used.
