"[Armchair mathematicians] are certain to find pleasure in this cornucopia of puzzles, brainteasers, and digressions.... The ideal book for dispelling the supposed drudgery of mathematics with its real magic."
"Stewart has a genius for explanation that allows details of the Poincaré conjecture and Riemann hypothesis to sit happily alongside a quip about a chicken crossing a Möbius strip.... Mathematics doesn't come more entertaining than this."
"The exciting side of math--puzzles, games and thrilling oddities."
"What positive integer is equal to its own Scrabble score when spelled out in full? Stewart...offers this and a hodgepodge of other puzzles, paradoxes, brainteasers, tricks, facts and jokes, which he accurately calls 'curiosities.'."
"Open one of the 179 'drawers' in Professor Stewart's cabinet, and you might find just a one-liner...or a seven-page essay on Fermat's last theorem.... The book can be devoured in one giant gulp or savored, one curiosity at a time."
