User Review - agricolaoval - LibraryThingA classic that I enjoyed immensely at the uni. Wigner has the rare gift of crystal clarity combined with the concern for his students. For most students group theory obviously is a mere tool, but this book made it a joy to study it for its own sake. Not recommended for holiday trips though. Read full review
