Abstract

The flow of heat without convection in the liquid crystal paraazoxyanisol seems definitely to orient these liquid crystals with their long axes perpendicular to the direction of the flow. This phenomenon, first observed by G.W. Stewart, has been independently verified by Donald 0. Holland and Leon M. Reynolds. The orientation is readily disturbed by convection and by a mechanical disturbance such as a rotation of the sample. The significance of this phenomenon is at present uncertain. The difficulty rests in an adequate theoretical treatment of such a non-homogeneous medium. Tests should be made of other liquid crystals.
