DESCRIPTION:Liquid crystalline elastomers can spontaneously deform by 100%
  as they lose and regain their order by heating or by illumination.  They 
 can also deform\, by rotating their order\, at low energy cost in response
  to applied stress at constant temperature. They form textures on deformat
 ion if their low cost shapes are incommensurate with boundaries. Their fer
 ro-electric forms are also likely to deform via textures\, for instance as
  their polarisation is switched by mechanical fields. I shall subject thes
 e exotic rubbers to temperature change during the lecture.
