Satan, Cantor, and Infinity by Raymond Smullyan - Hardcover USED Mind Boggling Puzzles
Only 1 left in stockThe author of What Is the Name of This Book? presents a compilation of more than two hundred challenging new logic puzzles—ranging from simple brainteasers to complex mathematical paradoxes.
From Publishers Weekly
In Smullyan's latest challenging collection of logic puzzles, the Sorcerer, a logician who uses logic so cleverly it seems like magic, visits an island where intelligent robots create other robots. King Zorn, Princess Annabelle, truth-telling knights and lying knaves lighten the presentation of puzzles as the Sorcerer explains the pioneering discoveries of mathematician Georg Cantor (1845-1918) who proved that there are different orders of infinity, and as he delves into paradoxes about probability, time and change. Smullyan ( The Lady or the Tiger? ) tosses in metapuzzles (which are solved on the basis of knowing that certain other puzzles can or cannot be solved) and explores self-referentiality, a property crucial to Kurt Godel's famous incompleteness theorem. The Sorcerer closes with a tale of how Satan is outwitted by a student of Cantor's. A mind-stretching entertainment for the serious, dedicated puzzle-solver.

The Chess Mysteries of Sherlock Holmes by Raymond Smullyan - Paperback
The Chess Mysteries of Sherlock Holmes : Fifty Tantalizing Problems of Chess Detection by Raymond M. Smullyan - Paperback
Join the master sleuth as he and Dr. Watson examine interrupted chess matches at clubs and country homes, examining the pieces' current positions to identify previous moves. Rather than predicting the outcome of these games, the Baker Street duo focus on past events, using the same variety of logical reasoning that unlocks the secrets to their ever-popular mysteries. Holmes instructs Watson (and us) in the intricacies of retrograde analysis in order to deduce on which square the white queen was captured, whether a pawn has been promoted, and which piece has been replaced by a coin. The mysteries grow increasingly complex, culminating in a double murder perpetrated by the devious Professor Moriarty.
Philosopher and logician Raymond Smullyan brilliantly recaptures the mood of Sir Arthur Conan Doyle's tales. Readers need only a knowledge of how the pieces move; the first puzzles explain all of the concepts that arise later on. These witty and challenging problems will captivate chess aficionados, puzzle enthusiasts, Sherlock Holmes fans, and everyone who relishes mysteries, crime stories, and tales of detection.
