How to make it, break it, hack it, crack it. The secret history of codes and code breaking. Simon Singh's best-selling title The Code Book now re-issued for the young-adult market. The Science of Secrecy from Ancient Egypt to Quantum Cryptography. Simon Singh brings life to an amazing story of puzzles, codes, languages and riddles -- revealing the continual pursuit to disguise and uncover, and to work out the secret languages of others. Codes have influenced events throughout history, both in the stories of those who make them and those who break them. 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. In addition to stories of intrigue and warfare, Simon Singh also investigates other codes, the unravelling of genes and the rediscovery of ancient languages and most tantalisingly, the Beale ciphers, an unbroken code that could hold the key to a USD20 million treasure.
