Various aspects of nonlinear phenomena will be studied by                       controlled experiments.                                                                                                                                         The first will address the problem of turbulence, in gas and                    liquid helium, in a Rayleigh Benard experiment of large physical                                                                                                size.  A study of the transitions from chaos to weak turbulence                 and then to develop turbulence is planned.                                                                                                                      The second will study the dynamics of interfaces between various                                                                                                states of liquid crystals, smecticA-smecticC, smectic                           A-isotropic phases.  The effects of crystal symmetries on the                   dendritic shapes will be studied.                                                                                                                               The third will be a continuation from the preceeding grant.  In                 R-B experiments on mercury the effects of noise and                             or a third frequency on the transition to chaos in                                                                                                              quasiperiodicity will be observed.                                                                                                                                                                                                                                                                                              Finally, in fluid-fluid interfaces of the Saffman-Taylor types, a                                                                                               number of puzzling questions remain on the selection and                                                                                                        stability of fronts and bubbles.
