Book Description
June 28, 1972, the day I reported to the United Stated Military Academy at West Point, one of our class's first military acts was to subscribe to the Cadet Code of Conduct, swearing not to lie, cheat or steal ... nor tolerate among us anyone who does. I also pledged, as a cadet, and later as an officer, to preserve, protect, and defend the constitution of the United States. Any future allegiance I incurred fell subordinate to these two.Perhaps that's why I developed an affinity to the flying safety field which resides in a sacred niche within the sphere of flying. At the pinnacle of this citadel of truth resides the accident investigation process ... where there is no room or tolerance for politics or innuendo.I accepted the job to investigate the April 9th, 2010 CV-22 Osprey accident with reservations concerning the magnitude of the task and the inherent barriers preventing the collection of evidence a half-a-world away. But I failed to account for the obstacles of full disclosure, politics, and the reluctance of the same entities that assigned me the task, to accept the controversial findings of the investigation.If, at this point, you have read the first few pages of this book looking for an indictment of the government, Air Force, or the contractors who supply weapons of war, put the book back on the shelf ... or click remove from the digital cart. This is no vendetta, tell-all, hatchet job. This book is about facts and truth. Over a period of five months, the Air Force CV-22 accident investigation board traveled thousands of miles, interviewed over one hundred witnesses, and collected mounds of evidence in an inhospitable environment searching for the reason an Osprey aircraft impacted the ground in the remote desert of eastern Afghanistan. The accident took the lives of four personnel aboard the accident airplane.The following pages chronicle the unpublished and exhaustive investigation process, ending with my opinion of the cause of the Osprey accident on th

Book Description
“A totally new and original work that stretches his talents to their fullest . . . welcome back, champ!”—The Detroit News In the twenty-third century pioneers have escaped the crowded earth for life in self-sustaining orbital colonies. One of the colonies, Rotor, has broken away from the solar system to create its own renegade utopia around an unknown red star two light-years from Earth: a star named Nemesis. Now a fifteen-year-old Rotorian girl has learned of the dire threat that nemesis poses to Earth’s people—but she is prevented from warning them. Soon she will realize that Nemesis endangers Rotor as well. And so it will be up to her alone to save both Earth and Rotor as—drawn inexorably by Nemesis, the death star—they hurtle toward certain disaster.

Book Description
The first edition of this award-winning book attracted a wide audience. This second edition is both a joy to read and a useful classroom tool. Unlike traditional textbooks, it requires no mathematical prerequisites and can be read around the mathematics presented. If used as a textbook, the mathematics can be prioritized, with a book both students and instructors will enjoy reading. Secret History: The Story of Cryptology, Second Edition incorporates new material concerning various eras in the long history of cryptology. Much has happened concerning the political aspects of cryptology since the first edition appeared. The still unfolding story is updated here. The first edition of this book contained chapters devoted to the cracking of German and Japanese systems during World War II. Now the other side of this cipher war is also told, that is, how the United States was able to come up with systems that were never broken. The text is in two parts. Part I presents classic cryptology from ancient times through World War II. Part II examines modern computer cryptology. With numerous real-world examples and extensive references, the author skillfully balances the history with mathematical details, providing readers with a sound foundation in this dynamic field. FEATURES Presents a chronological development of key concepts Includes the Vigenère cipher, the one-time pad, transposition ciphers, Jefferson’s wheel cipher, Playfair cipher, ADFGX, matrix encryption, Enigma, Purple, and other classic methods Looks at the work of Claude Shannon, the origin of the National Security Agency, elliptic curve cryptography, the Data Encryption Standard, the Advanced Encryption Standard, public-key cryptography, and many other topics New chapters detail SIGABA and SIGSALY, successful systems used during World War II for text and speech, respectively Includes quantum cryptography and the impact of quantum computers
