M.D. Sanford, Felician College "...engaging, provocative, and definitely worth reading and thinking about." MAA Reviews, Fernando Q. Gouvea "...recommended reading--for its thought-provoking ideas and lively writing--for those with a serious interest in the mathematics of ancient Greece and medieval Islam." - Mathematical Reviews, J.L.
