   Title: Soap Films and Time Machines

Abstract.  Soap films are physically double layers of soap
molecules with liquid between, which try to minimize their area. They
can join three at a time along "triple lines," and this makes them
difficult to model mathematically.  I will present my own mathematical
model of soap films involving covering spaces, which turns out to have
much in common with wormholes, stargates, and time machines.  I will
have live soap films, and computer demonstrations of how stargates and
time machines really work.
