Title: Puzzling realities
Review: David Wells' Book of curious & interesting Puzzles is an outstanding collection of all kinds of puzzles, arithmetic, visual, plain intelligent etc. The book is interesting, because it tells you the history of a particular puzzle, beginning with the oldest ever, found at Luxor, Egypt, in 1650 BC.You can use these puzzles in a math class, but also to solve them together with friends or collegues. I bought it to help me find a solution for picturing a four dimensional object. Everyone should have it at home for his or her children or visitors.It's great fun.
