The Knots Puzzle Book: A Collection of Interesting Mathematical Ideas

Most of us can tell the difference between a reef knot and a granny, but can we tell when a knot is not a knot at all, but an unknot. Through a series of interesting puzzles, Heather McLeay leads us gently into an understanding of the theory of knots.Many of them can be solved by looking and thinking, but for others, having a length of real string or rope to hand would be a great help. In all, this is a colorful and original book, offering a delightful introduction to knot theory. It is one which will appeal to anyone with a liking for puzzles and an interest in curious ideas of a mathematical nature.
