About this deal

The reader will learn how to use each cipher as well as the best approaches when attempting to attack an uncracked cipher with a step-by-step guide. Goes through early basic codes (letter substitution for example) through the WWII Enigma code (which I almost feel like I could now crack! The story blends philosophy, history, theory and language into a surprisingly lively (considering the characters are monks) human story. The tentative and suspicious negotiations between Poland, France and the UK were convoluted and lengthy.

That being said, I could hardly imagine even approaching the problems Elonka Dunin and Klaus Schmeh have tackled. Even though her high school counselor told her girls didn’t become scientists, she decided she would. During the dark days of 1941, as Britain stood almost alone against the the Nazis, this remarkable achievement seemed impossible. Perhaps the most famous, and amongst the most imaginative and unconventional, was Alan Turing, so this book fully deserves a place on my list. The brilliance of the Bletchley Park codebreakers is undoubted, but it must be remembered that they did not start from scratch; they built on the work of the cryptanalysts of the Polish Cipher Bureau, who had first broken Enigma ciphers in 1932, and then passed on all their knowledge to Britain in 1939, before the war began.I dare you to find a more diverse, a more mind-blowing, a more intriguing collection of stories about codes and code breaking.

From the best-selling author of Fermat's Last Theorem, The Code Book is a history of man's urge to uncover the secrets of codes, from Egyptian puzzles to modern day computer encryptions. The betrayal of Mary Queen of Scots and the cracking of the enigma code that helped the Allies in World War II are major episodes in a continuing history of cryptography.A series of three books, Drosnin’s philosophy includes the idea that the Torah has extra-terrestrial origins. Through the publication of several such guidebooks, Elonka Dunin stood out as primus inter pares among our experts on codes.

He is a professor of history at Tulane and was CEO of the Aspen Institute, chair of CNN, and editor of Time. When Jennifer Shea married Russel Redmond, they made a decision to spend their honeymoon at sea, sailing in Mexico. With clear mathematical, linguistic and technological demonstrations of many of the codes, as well as illustrations of some of the remarkable personalities behind them – many courageous, some villainous – The Code Book traces the fascinating development of codes and code-breaking from military espionage in Ancient Greece to modern computer ciphers, to reveal how the remarkable science of cryptography has often changed the course of history. In this code-breaking book for kids, explore the mysterious world of clever codes and cyphers that have been invented over the years.A gentle and enthralling introduction for the novice with scores of challenge problems, a guide for the student of classical cryptology, and a delight for the expert with dozens of unsolved problems to attack. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Cryptography can seem like a daunting subject, but in this book Elonka and Klaus have made it understandable, approachable, and most of all: fun! When a great biographer combines his own fascination with science and a superb narrative style, the result is magic. An inspiring, profusely illustrated encyclopedia of challenges, set in their original cultural and historical context.

So when my brother Reuben, who has Down's syndrome sent me a message from the isolation of a care home in the pandemic, I knew he was in trouble. He argues that the West must give higher priority to assisting the region and reorient its strategies so as to emphasize the political and administrative dimensions of economic reconstruction. A mix of maths, cryptography and puzzles from the teenager who hit the headlines with her encryption algorithm. But when they discover a secret message in an old book, that says: ‘Mary Jordan did not die naturally’, the mystery has very much found them. It captures the harsh realities of life for those who spent the war in less lauded, yet equally important, secret roles.Enigma: How Breaking the Code Helped Win World War II tells the story of Bletchley’s role in defeating U-boats in the Atlantic, breaking the Japanese codes, helping the Allies to victory in North Africa, deciphering the German military intelligence code, learning of most German positions in western Europe before the Normandy Landings, defeating the Italian Navy in the Mediterranean, and helping sink the German battleship Scharnhorst off Norway. Each chapter details a new cipher technique while stressing the craft’s terminology, and each historical example comes with a complete backstory. Imaginative and unconventional thinking was essential if Britain was to overcome the challenge of Nazi Germany.
