Based on the interactive program Interquanta, Quantum Mechanics on the Macintosh , uses 3-D graphics to guide the student through computer experiments in the quantum mechanics of free particle motion, bound states and scattering, tunnelling, two-particle interactions and more. It also inc ludes a section on special functions of mathematical physics. With more than 200 problems, the text and the accompanying computer programs offer students practical experiences in using such hard-to-visualize concepts such as complex amplitudes, eigenvalues and scattering cross sections. The diskettes included with the book provide two versions of the programs, one for use in computers with a mathematical coprocessor and the other optimized for machines without a coprocessor.
