Peter Winkler is at it again. Following the enthusiastic reaction to "Mathematical Puzzles: A Connoisseur's Collection", Peter has compiled a new collection of elegant mathematical puzzles to challenge and entertain the reader. The puzzles in this collection include an eclectic collection of twists on old favorites, "severe" difficulty puzzles, and puzzles that were recently solved or remain unsolved.This book is for lovers of mathematics, lovers of puzzles, lovers of a challenge. Most of all, it is for those who think that the world of mathematics is orderly, logical, and intuitive - and are ready to learn otherwise! "This wonderful book presents, from diverse sources and with wit and humor, many interesting and challenging problems, both mathematical and otherwise. Like its predecessor, it is a must for the shelves of a problem connoisseur." - Andy Liu"
