Download or read book Unsolved written by Craig P. Bauer and published by Princeton University Press. This book was released on 2019-06-18 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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"--

Download or read book Penrose Tiles to Trapdoor Ciphers and the Return of Dr Matrix written by Martin Gardner and published by American Mathematical Soc.. This book was released on 2020-10-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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

Download or read book World War I and the Foundations of American Intelligence written by Mark Stout and published by University Press of Kansas. This book was released on 2023-11-16 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ask an American intelligence officer to tell you when the country started doing modern intelligence and you will probably hear something about the Office of Strategic Services in World War II or the National Security Act of 1947 and the formation of the Central Intelligence Agency. What you almost certainly will not hear is anything about World War I. In World War I and the Foundations of American Intelligence, Mark Stout establishes that, in fact, World War I led to the realization that intelligence was indispensable in both wartime and peacetime. After a lengthy gestation that started in the late nineteenth century, modern American intelligence emerged during World War I, laying the foundations for the establishment of a self-conscious profession of intelligence. Virtually everything that followed was maturation, reorganization, reinvigoration, or reinvention. World War I ushered in a period of rapid changes. Never again would the War Department be without an intelligence component. Never again would a senior American commander lead a force to war without intelligence personnel on their staff. Never again would the United States government be without a signals intelligence agency or aerial reconnaissance capability. Stout examines the breadth of American intelligence in the war, not just in France, not just at home, but around the world and across the army, navy, and State Department, and demonstrates how these far-flung efforts endured after the Armistice in 1918. For the first time, there came to be a group of intelligence practitioners who viewed themselves as different from other soldiers, sailors, and diplomats. Upon entering World War II, the United States had a solid foundation from which to expand to meet the needs of another global hot war and the Cold War that followed.
Download or read book The Zodiac Revisited Volume 2 written by Michael Cole and published by Twin Prime Publishing. This book was released on 2020 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand History's Most Enigmatic Serial Killer In December of 1968, a serial killer began orchestrating a campaign of terror in the San Francisco Bay Area. Not satisfied with the simple act of murder, he taunted law enforcement and the public by writing letters to local newspapers. Through often cryptic and bizarre content—including four ciphers, three (now two) of which have never been solved—the psychopath played a twisted game. Reporters dubbed the man the "Cipher Killer," but the murderer chose a different name for himself: the Zodiac. Eventually, he would claim to have murdered thirty-seven. Law enforcement, however, could only account for five. In 1971, authenticated communications with the Zodiac ceased. The elusive fugitive resurfaced briefly three years later, sending a small number of communiqués, before disappearing for good. What started out with shocking abruptness slowly dissolved into mysterious uncertainty. To this day, the Zodiac's true identity remains one of the twentieth century's greatest mysteries... Having established an analytical foundation in Volume 1, Michael uses Volume 2 to look across the entirety of the case and identify meaningful threads of commonality, exploring subjects such as the killer's methodology, persona, and ciphers.
