The connection between the formation of internal waves in fluids and the dynamics of homeomorphisms of the circle was investigated by oceanographers in the 90s and resulted in novel experimental observations (Maas et al, 1997). The specific homeomorphism is given by a ``chess billiard" and has been considered ...
