SUMMARY:Skipping Stones\, Ruined Roads and those Dam Oscillations - Neil B
 almforth\, University of British Columbia
DTSTART:20140313T113000Z

UID:TALK49881@talks.cam.ac.uk
CONTACT:Catherine Pearson
DESCRIPTION:In this talk I will describe recent results\n     on the model
 ling of how the collision of an object with a\n     moving\, deformable su
 rface can generate an apparent\n     ``super-elastic'' bounce. The phenome
 non allows towed\n     paddles to skip continually at high speed over wate
 r\n     (demanding an extension of models of skipping stones) and\n     to
  ``washboard'' layers of sand or mud with only a single\n     passage over
  that substrate (in contrast to the\n     conventional explanation for was
 hboard roads). Along the\n     way\, I will mention a related instability 
 involving the\n     sloshing of a fluid reservoir coupled to oscillations 
 of\n     a movable dam\, a hydrodynamic analogue of musical\n     instrume
 nts like the clarinet.
