Autorenporträt
Quantum Mechanics on the Macintosh uses extensive 3-D graphics and more than 200 problems to guide the student through computer experiments in the quantum mechanics of free particle motion, bound states and scattering, tunneling, two-particle interactions, and more. The diskette included with the book provides programs in versions optimized for computers with or without mathematical coprocessors.
