THE question posed by this book turns out to be a real toughie, but nevertheless the authors urge you to answer it with a British 50p coin, a 2p coin and a beer mat.

With a nice emphasis on practical experiments, the authors do a refreshing job of bringing out the mathematics you learned in school but sadly never knew why. And they show just how intuitive it can be.
