Rotating Superfluids

Rotation of a fluid, particularly studying phenomena affected by Coriolis forces, plays a significant role in nearly all branches of fluid dynamics. Quantum fluids are no exception, as evidenced by remarkable devices such as ``Rota'' in Helsinki. This talk concerns the early days of rotating superfluids, starting long before superfluid helium-3 appeared on the scene. I will attempt to describe some of the early experiments, how the apparatus was designed, and what the experiments revealed. There has been so much activity in this area, I will discuss mostly experiments in my own fields of interest. Time will not permit an exhaustive review of this fascinating subject.
