With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations. What came to be known as Fermat's Last Theorem looked simple; proving it, however, became the Holy Grail of mathematics, baffling its finest minds for more than 350 years. In Fermat's Enigma--based on the author's award-winning documentary film, which aired on PBS's "Nova"--Simon Singh tells the astonishingly entertaining story of the pursuit of that grail, and the lives that were devoted to, sacrificed for, and saved by it. Here is a mesmerizing tale of heartbreak and mastery that will forever change your feelings about mathematics.
]]>Im Informationszeitalter ist die Angst, die kryptographische Verbesserungen antreibt, kapitalistischer wie auch liberalistischer Natur. Unternehmen benötigen das Chiffrieren, um sicherzustellen, dass ihre Geheimnisse nicht in die Hände der Konkurrenz und der Regulierungsbehörden fallen, und gewöhnliche Leute brauchen es, um in einer freien Gesellschaft ihre alltägliche Kommunikation privat zu halten. Umgekehrt kommt der Kampf um größere Dechiffriergewalt vonseiten der besagten Konkurrenten und der Regierungen, die auf der Hut vor Aufständen sind. Geheime Botschaften ist eine hervorragendes Buch für alle, die verstehen wollen, wie sich das Bedürfnis nach Privatsphäre durch die Kryptographie manifestiert hat. Singhs zugänglicher Stil und verständliche Erläuterungen von komplexen Algorithmen umgehen die obskuren mathematischen Details, ohne zu sehr zu vereinfachen. --Therese Littleton

In 1914-18 it was by deciphering an incriminating German telegram, which brought America militarily onside; in 1939-45 it was by employing the most brilliant of crypto-boffins at Bletchley Park, who, via the Colossus decryption computer, ensured the Allies were always able to second guess the Nazi war machine.
The final section of the book, which describes attempts to encrypt--and decrypt--the Web, underlines why codes are of crucial topicality. Should vital material on the Net be encoded, or does that infringe free exchange of information, the very essence of cyberspace? Singh offers a readable, lucid and well informed take on this, much as he tackles every other subject in his diverting and illuminating book. --Sean Thomas
