"Sussman and Wisdom make a bold experiment in communicating mathematical physics: they say exactly what they mean. Even a computer can follow their equations. By using this textbook, students painlessly master Scheme, a minimalist programming language, at the same time. This empowers them to go beyond the simplistic integrable systems that dominate the traditional course, to the richness of nonlinear resonance and chaotic dynamics. The hard core of rigor is softened by a personal and enthusiastic writing style"
How come I never heard of this before?
