THE USEFULNESS OF ENERGY INTEGRALS
Most people are familiar with the concept of constant
energy from either planets in motion or a falling stone.
This idea can be extended most usefully to equations
which govern propagation. We shall show how those
ideas have proved useful in the study of many problems
such as how sound energy spreads in space or how airplanes
develop shocks.

TRANSONIC FLOWS
Colloquium: Time dependent gas dynamics is governed by hyperbolic equations,
and shocks are inevitable. In two cases the equations simplify to a single
equation, but of mixed type, i.e., it could be elliptic or hyperbolic.
Properties and paradoxes of these flows will be described.
