Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one--before Gardner--had written about mathematics like this. They continue to be a marvel. This volume was originally published in 1989 and contains columns from published 1976-1978. This 1997 MAA edition contains three new columns written specifically for this volume including the resurrection of the lamented Dr. Matrix.

"In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize-winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics--in some cases both--to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers"--

Uncover the truth about atheism in the book Oliver Sacks calls, "a revelation. . . I don’t think anyone can match the (devastating!) clarity, intensity, and honesty which Dan Barker brings to the journey—faith to reason, childhood to growing up, fantasy to reality, intoxication to sobriety." ADVANCE PRAISE FOR GODLESS “Valuable in the human story are the reflections of intelligent and ethical people who listen to the voice of reason and who allow it to vanquish bigotry and superstition. This book is a classic example.” —CHRISTOPHER HITCHENS author of God is Not Great “The most eloquent witness of internal delusion that I know—a triumphantly smiling refugee from the zany, surreal world of American fundamentalist Protestantism—is Dan Barker.” —RICHARD DAWKINS author of The God Delusion “Godless was a revelation to me. I don’t think anyone can match the (devastating!) clarity, intensity, and honesty which Dan Barker brings to the journey—faith to reason, childhood to growing up, fantasy to reality, intoxication to sobriety.” —OLIVER SACKS authors of Musicophilia In Godless, Barker recounts his journey from evangelical preacher to atheist activist, and along the way explains precisely why it is not only okay to be an atheist, it is something in which to be proud.” —MICHAEL SHERMER publisher of Skeptic Magazine “Godless is a fascinating memoir and a handbook for debunking theism. But most of all, it is a moving testimonial to one man’s emotional and intellectual rigor in acclaiming critical thinking.” —ROBERT SAPOLSKY author of Why Zebras Don’t Get Ulcers

"Featuring facsimilies of the actual coded documents, the book delves into nearly every matter conceivable for a paramilitary organisation, ranging from the importation of explosives to the use of IRA informants in the gardai. Documents detail the IRA's secret agreement with the Soviet Union and its attempts to provide military assistance to China; military espionage in America; plans to stage a gas attack on Dublin; the IRA's infiltration of the GAA and control of the Kerry football team and the struggle with Eamon de Valera and Fianna Fail. The book provides an unnerving insight into how the IRA saw itself and conducted its dangerous business in secrecy."--BOOK JACKET.
