This is not the book I thought I’d be writing. When, about a decade ago, I initiated the
discussions that led to our Computational Physics course, I thought we would teach mainly
physics in it. The . . . . .

Ever since its discovery, the notion of Berry phase has permeated through all branches of physics.
Over the last three decades, it was gradually realized that the Berry phase of the electronic wave

Most sounds of interest consist of complex, time-dependent admixtures of tones of diverse frequencies and variable amplitudes. To detect and process these signals, the ear employs a highly nonlinear, . . . . .
