Mathematica is a powerful computer language that allows the tight integration of symbolic, numeric, and graphic techniques. In Mathematica for Scientists and Engineers: Using Mathematica to do Science, Richard Gass provides a guide for scientific researchers, engineers, and students on using the power of Mathematica to solve scientifically interesting problems. On the left, for instance, is a nonuniform cross-section of a pipe, the partial differential equation that governs wave motion in the pipe, the Mathematica code that solves the equation, and a density plot of the excess pressure in the pipe.
