A comprehensive and fun guide to Backgammon

Backgammon is one of the oldest games in the world, the origins of which date back some 5000 years - and it's still going strong. It enjoyed a huge resurgence in the 1970s, and then again in the 1990s with the popularity of the Internet, where millions of people play tournaments online every day.

Today, backgammon's following in the UK is huge, with a dedicated British Isles Backgammon Association, and hundreds of face-to-face tournaments taking place across the UK every year.

In this book, backgammon expert Chris Bray walks you through the basics of setting up a board, opening strategies, middle and end-game tactics, and tips on when to make key moves. You'll also get to grips with basic probabilities, the doubling cube and the 25% rule. And if you want to take your gaming further, there's plenty of advice to get you started in tournament backgammon, as well as playing online.

Suitable for both beginners and experienced player looking for more tips and techniques, "Backgammon For Dummies" includes coverage on: Starting and Playing the GameHandling the Middle GameBearing Off (The Last Lap)Varying the PlayAbout the author

Research on massive stars is undergoing a period of rapid progress, with long-held convictions being shown to be incomplete. While these stars are relatively few in number, they are the main driver of chemical and dynamical evolution in galaxies through their stellar winds and explosive deaths in core-collapse supernovae. Furthermore the impact of massive stars is widely recognized in many areas, as they are often used as tools to interpret the conditions and processes arising in different environments. In parallel, the development of new instrumentation, analysis techniques and dedicated surveys across all possible wavelengths have delivered large amounts of exquisite new data. These data are now providing a harsh test for the current state-of-the-art theoretical calculations of massive star birth, evolution and death. IAU Symposium 329 covers these topics and is therefore an invaluable resource for researchers in the field of massive stars and their evolution.

The fame of French scientist and geographer Joseph N. Nicollet rests upon his monumental map and report of the Upper Mississippi Valley. The map, published by the United States government in 1843, remained the foundation of Upper Mississippi cartography until the era of modern surveys. Nicollet's journals illuminate the 1836 trip to the source of the Mississippi and a journey up the St. Croix River in 1837. His day-by-day accounts include careful notes on geographical features, flora and fauna, and the aurora borealis. But above all, his keen observations on the customs and culture of the Ojibwe Indians provide the first systematic recording and a remarkably sympathetic depiction of the people of the area. Martha Bray's introduction and annotation to this translation by Andre Fertey provide a brief biography of one of the fathers of American science.

In 1838 and 1839 French scientist Joseph N. Nicollet led two U.S. government-sponsored expeditions into the land between the Missouri and Mississippi rivers. His findings, published in 1843 in the first authentic map of the region, influenced the future of cartography in the United States for generations.

This book contains the translations of Nicollet's journals, letters, and notes written during those expeditions, which visited such familiar landmarks as Fort Pierre, the Coteau des Prairies, and Devil's Lake in the Dakotas and the Pipestone Quarry in Minnesota. Nicollet came into contact with many Dakota people in the region, and his detailed observations are a valuable record of their way of life.
