In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

The Amazon Basin is arguably both one of the least-known and the most complex linguistic regions in the world. It is the home of some 300 languages belonging to around twenty language families, plus more than a dozen genetic isolates, and many of these languages (often incompletely documented and mostly endangered) show properties that constitute exceptions to received ideas about linguistic universals. This book provides an overview in a single volume of this rich and exciting linguistic area. The editors and contributors have sought to make their descriptions as clear and accessible as possible, in order to provide a basis for further research on the structural characteristics of Amazonian languages and their genetic and areal relationships, as well as a point of entry to important cross-linguistic data for the wider constituency of theoretical linguists.
This collection of original papers presents current research on linguistic aspects of the Spanish used in the United States. The authors examine such topics as language maintenance and language shift, language choice, the bilingual's discourse patterns, varieties of Spanish used in the United States, and oral proficiency testing of bilingual speakers. In view of the fact that Hispanics constitute the largest linguistic minority in the United States, the pioneering work in the area of sociolinguistic issues in the U.S. Spanish presented here is of great importance.
