The "Hidden Logic of Sudoku" provides the first systematic perspective of the logical symmetries of the popular game. These are fully exploited to define new graphical representations, new kinds of resolution rules and a precedence ordering of the rules consistent with their logical complexity. The set of rules defined in the book is illustrated with a hundred of puzzles together with their full resolution paths. It suffices to solve almost any puzzle without making guesses or assuming the uniqueness of a solution. It has been fed into an Artificial Intelligence (AI) engine and a large database of puzzles has been processed, leading to a precise evaluation of the efficiency of each rule. The book is intended for both advanced Sudoku players (who will discover many new facets of the game and a new, systematic approach to the resolution rules) and for teachers or students of Logic or AI (who will appreciate the strict logical foundations).

Winner of the 2014 Sami Rohr Prize for Jewish Literature A thousand years ago, the most perfect copy of the Hebrew Bible was written. It was kept safe through one upheaval after another in the Middle East, and by the 1940s it was housed in a dark grotto in Aleppo, Syria, and had become known around the world as the Aleppo Codex. Journalist Matti Friedman’s true-life detective story traces how this precious manuscript was smuggled from its hiding place in Syria into the newly founded state of Israel and how and why many of its most sacred and valuable pages went missing. It’s a tale that involves grizzled secret agents, pious clergymen, shrewd antiquities collectors, and highly placed national figures who, as it turns out, would do anything to get their hands on an ancient, decaying book. What it reveals are uncomfortable truths about greed, state cover-ups, and the fascinating role of historical treasures in creating a national identity.
