Almost as soon as writing was invented, so too were the devious means to hide messages and keep them under the wraps of secrecy.<br><br>In <i>50 Codes that Changed the World</i>, Sinclair McKay explores these uncrackable codes, secret cyphers and hidden messages from across time to tell a new history of a secret world. From the temples of Ancient Greece to the court of Elizabeth I; from antique manuscripts whose codes might hold prophecies of doom to the modern realm of quantum mechanics, you will see how a few concealed words could help to win wars, spark revolutions and even change the faces of great nations.<br><br><FONT>
