Book Description
United States Diplomatic Codes and Ciphers, 1775-1938 is the first basic reference work on American diplomatic cryptography. Weber's research in national and private archives in the Americas and Europe has uncovered more than one hundred codes and ciphers. Beginning with the American Revolution, these secret systems masked confidential diplomatic correspondence and reports.During the period between 1775 and 1938, both codes and ciphers were employed. Ciphers were frequently used for American diplomatic and military correspondence during the American Revolution. At that time, a system was popular among American statesmen whereby a common book, such as a specific dictionary,was used by two correspondents who encoded each word in a message with three numbers. In this system, the first number indicated the page of the book, the second the line in the book, and the third the position of the plain text word on that line counting from the left. Codes provided the most common secret language basis for the entire nineteenth century.Ralph Weber describes in eight chapters the development of American cryptographic practice. The codes and ciphers published in the text and appendix will enable historians and others to read secret State Department dispatches before 1876, and explain code designs after that year.

Book Description
Samuel Steward (1909-93) was an English professor, a tattoo artist for the Hells Angels, a sexual adventurer who shared his considerable range of experiences with Alfred Kinsey, and a prolific writer of everything from scholarly articles to gay erotica (under the penname Phil Andros). Given this biography, he sounds like a most unlikely contributor to a trade magazine like the Illinois Dental Journal.

Book Description
NEW YORK TIMES BESTSELLER • Turn: Washington’s Spies, now an original series on AMC Based on remarkable new research, acclaimed historian Alexander Rose brings to life the true story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and deep into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed men who inhabited this wilderness of mirrors—including the spymaster at the heart of it all. In the summer of 1778, with the war poised to turn in his favor, General George Washington desperately needed to know where the British would strike next. To that end, he unleashed his secret weapon: an unlikely ring of spies in New York charged with discovering the enemy’s battle plans and military strategy. Washington’s small band included a young Quaker torn between political principle and family loyalty, a swashbuckling sailor addicted to the perils of espionage, a hard-drinking barkeep, a Yale-educated cavalryman and friend of the doomed Nathan Hale, and a peaceful, sickly farmer who begged Washington to let him retire but who always came through in the end. Personally guiding these imperfect everyday heroes was Washington himself. In an era when officers were gentlemen, and gentlemen didn’ t spy, he possessed an extraordinary talent for deception—and proved an adept spymaster. The men he mentored were dubbed the Culper Ring. The British secret service tried to hunt them down, but they escaped by the closest of shaves thanks to their ciphers, dead drops, and invisible ink. Rose’s thrilling narrative tells the unknown story of the Revolution–the murderous intelligence war, gunrunning and kidnapping, defectors and executioners—that has never appeared in the history books. But Washington’s Spies is also a spirited, touching account of friendship and trust, fear and betrayal, amid the dark and silent world of the spy.

Book Description
This book is a study of Blaise Pascal's defence of Christian belief in the Pensées. Michael Moriarty aims to expound--and in places to criticize--what he argues is a coherent and original apologetic strategy. Setting out the basic philosophical and theological presuppositions of Pascal's project, the present volume draws the distinction between convictions attained by reason and those inspired by God-given faith. It also presents Pascal's view of the contradictions within human nature, between the 'wretchedness' (our inability to live the life of reason, to attain secure and durable happiness) and the 'greatness' (the power of thought, manifested in the very awareness of our wretchedness). His mind-body dualism and his mechanistic conception of non-human animals are discussed. Pascal invokes the biblical story of the Fall and the doctrine of original sin as the only credible explanation of these contradictions. His analysis of human occupations as powered by the twin desire to escape from painful thoughts and to gratify one's vanity is subjected to critical examination, as is his conception of the self and self-love. Pascal argues that just as Christianity propounds the only explanation for the human condition, so it offers the only kind of happiness that would satisfy our deepest longings. He thus reasons that we have an interest in investigating its truth-claims as rooted in the Bible and in history. The closing chapters of this book discuss Pascal's view of Christian morality and the famous 'wager' argument for opting in favour of Christian belief.

Book Description
This is a detailed history of one of the most important and dramatic episodes in modern science, recounted from the novel vantage point of the dawn of the information age and its impact on representations of nature, heredity, and society. Drawing on archives, published sources, and interviews, the author situates work on the genetic code (1953-70) within the history of life science, the rise of communication technosciences (cybernetics, information theory, and computers), the intersection of molecular biology with cryptanalysis and linguistics, and the social history of postwar Europe and the United States. Kay draws out the historical specificity in the process by which the central biological problem of DNA-based protein synthesis came to be metaphorically represented as an information code and a writing technologyand consequently as a book of life. This molecular writing and reading is part of the cultural production of the Nuclear Age, its power amplified by the centuries-old theistic resonance of the book of life metaphor. Yet, as the author points out, these are just metaphors: analogies, not ontologies. Necessary and productive as they have been, they have their epistemological limitations. Deploying analyses of language, cryptology, and information theory, the author persuasively argues that, technically speaking, the genetic code is not a code, DNA is not a language, and the genome is not an information system (objections voiced by experts as early as the 1950s). Thus her historical reconstruction and analyses also serve as a critique of the new genomic biopower. Genomic textuality has become a fact of life, a metaphor literalized, she claims, as human genome projects promise new levels of control over life through the meta-level of information: control of the word (the DNA sequences) and its editing and rewriting. But the author shows how the humbling limits of these scriptural metaphors also pose a challenge to the textual and material mastery of the genomic book of life.
