"Dynamic transitions in liquid drops"

Drops are a common feature in a wide range of natural and industrial liquid processes including for example rainfall, microfluidics, fuel injection systems, and pesticide spraying.  A fluid droplet is ostensibly so simple a system that one might suppose that everything about it is thoroughly understood.   One the contrary, we continually find new and surprising dynamical behaviors.   I will present several examples studied in our lab that include drops that respond to light, climbing drops, and splashing from drop impact.
