From the mathematics of mazes, to cones with a twist, and the amazing sphericon-and how to make one-Ian Stewart is back with more mathematical stories and puzzles that are as quirky as they are fascinating. We find out about the mathematics of time travel, explore the shape of teardrops (which are not tear-drop shaped, but something much, much stranger!), dance with dodecahedra, and play the game of Hex, amongst many more strange and delightful mathematical diversions.
