Presentation title and abstract:

Understanding Explosions: From Catastrophic Accidents to the Creation of
the Universe

Explosions occur when energy is released into a physical system faster
than it can be smoothly equilibrated.  Then the pressure increases
rapidly, shock waves form, and these waves propagate throughout the
system. This very general description covers scenarios that range from the
Big Bang, to thermonuclear explosions in stars, to magnetohydrodynamic
explosions in the sun, and to most of the chemical explosions on earth. In
each case, the explosion event is short and dramatic, and it is usually
with excitement and alarm that we see, hear, or feel the effects. In some
cases, we have attempted to control an explosion, as in propulsion and
combustion systems when we try to use the explosion process and the output
energy. In this presentation, we examine some of the fundamental fluid and
chemical properties and transitions that are the underpinnings of all
explosions. We consider how the transitions that occur on the smallest
scales can have catastrophic large-scale effects.
