En esta extraordinaria parodia de Las mil y una noches, Raymond Smullyan te transportará a un mundo misterioso en el que Sherezade, una joven encantadora y de un ingenio lógico fantástico, está en peligro de perder su cabeza al amanecer. En la crispante penumbra del harén, Sherezade tienta al monarca a postergar su ejecución planteándole los enigmas lógicos y matemáticos más deliciosamente tortuosos que jamás se hayan inventado. Estos les mantienen ocupados durante muchas noches y así, mientras el rey trata de adivinar la respuesta, la doncella se mantiene a salvo. El enigma de Sherezade incluye maravillosas adivinanzas antiguas y un total de 225 acertijos originales, verdaderamente diabólicos. Hay trucos lógicos y juegos con cifras, metaproblemas, ejercicios de verdad y mentira, rompecabezas intrincados a la manera de Gödel, paradojas dificilísimas, además de una excursión a un nuevo campo de la lógica inventado por Smullyan, llamado lógica coactiva, en el cual la respuesta a un problema en realidad puede modificar el destino del que lo resuelve. Cualquier lector postergará sus propósitos ante los desafíos lógicos de esta bella muchacha.
In this book, Raymond Smullyan, grand vizier of the logic puzzle, joins Scheherazade, a charming young woman of «fantastic logical ingenuity», to give us 1001 hours of brain-teasing fun. Scheherazade, we find, has gotten back into hot water with the king, and is once more in danger of losing her head at down. But, thinking quickly, she tempts the king to stay her execution by posing him the most delightfully devious mathematical and logic puzzle ever invented. They keep him guessing for many more nights until the fatal hour has passed, and she keeps her head. The Riddle of Scheherazade includes several wonderful old chestnuts and many fiendishly original puzzles. There are logic tricks and number games, metapuzzles (puzzles about puzzles), liar/truth-teller exercises, Gödelian brain twisters, baffling paradoxes, and an excursion, under Scheherazade’s expert guidance, into an amusing new field invented by Smullyan, called «coercive» logic, in which the answer to a problem can actually change the fate of the puzzler! An absolute must for all puzzle fans—from the middle-school whiz to the sophisticated mathematician or computer scientist.
