  We prove that on the typical translation surface the flow in almost every
pair of directions are not isomorphic to each other and are in fact disjoint.
It was not known if there were any translation surfaces other than torus covers
with this property. We provide an application to the convergence of `circle
averages' for the flow (away from a sequence of radii of density 0) for such
surfaces. Even the density of a sequence of 'circles' was only known in a few
special examples.
