Knowing that the most exciting math is not taught in school, Professor Ian Stewart has spent years filling his cabinet with intriguing mathematical games, puzzles, stories, and factoids intended for the adventurous mind. This book reveals the most exhilarating oddities from Professor Stewarts legendary cabinet.Inside, you will find hidden gems of logic, geometry, and probabilitylike how to extract a cherry from a cocktail glass (harder than you think), a pop-up dodecahedron, and the real reason why you cant divide anything by zero. Scattered among these are keys to Fermats last theorem, the Poincar conjecture, chaos theory, and the P=NP problem (youll win a million dollars if you solve it). You never know what enigmas youll find in the Stewart cabinet, but theyre sure to be clever, mind-expanding, and delightfully fun.
