Bücher von David Wells

The appeal of games and puzzles is timeless and universal. In this unique book, David Wells explores the fascinating connections between games and mathematics, proving that mathematics is not just about tedious calculation but imagination, insight and intuition. The first part of the book introduces games, puzzles and mathematical recreations, including knight tours on a chessboard. The second part explains how thinking about playing games can mirror the thinking of a mathematician, using scientific investigation, tactics and strategy, and sharp observation. Finally the author considers game-like features found in a wide range of human behaviours, illuminating the role of mathematics and helping to explain why it exists at all. This thought-provoking book is perfect for anyone with a thirst for mathematics and its hidden beauty; a good high school grounding in mathematics is all the background that is required, and the puzzles and games will suit pupils from 14 years.

50 YEARS OF CARING FOR SEAFARERS IN PORT HOUSTON celebrates the five-decade history of the Houston International Seafarers' Center: how it was founded, how it has served seafarers and led the field of seafarers; welfare over the years, and the generous and enterprising people who made it all possible. This history shows the value of partnerships; especially partnerships between the business world, the Port Authority, and local religious communities. Without these partnerships the Houston project would have stalled or failed at several key junctures. The value of the Houston Port Authority's willingness to partner with others throughout the history of seafarers' welfare in Houston cannot be overstated. At its heart, the story of seafarers' service in Houston is about relationships; about connecting people. Because hundreds of staff and thousands of volunteers were willing to invest their time in the lives of others, over the last 50 years more than two million seafarers have been welcomed in the Seafarers' Center and millions more have been cared for by chaplains and ship visitors throughout the Port. "I was a stranger and you welcomed me."
