Summary: When time reversal is broken, the viscosity tensor can have a nonvanishing odd part. In two dimensions, and only then, such odd viscosity is compatible with isotropy. Here we examine elementary and basic features of odd viscosity by considering solutions of the wave and Navier-Stokes equations for hypothetical fluids, where the stress is dominated by odd viscosity.
