A Hen and a Half: Intriguing Conundrums, Confusing Paradoxes, Baffling Conjectures and Challenging Puzzles John Driscoll

A book of puzzles, lateral thinking problems, conundrums, magic, and interesting arithmetical tricks sometimes progressing to and using extremely basic mathematical and scientific principles. The author focuses particularly on situations and solutions to problems that at first glance appear to be incorrect, paradoxical, or even impossible. Often those with a love for problems and puzzles do not always readily understand the solutions. However, audiences confounded by a problem are generally delighted to have the answer given and explained in a straightforward and logical manner. In this book that means occasionally including a simple mathematical solution, even though sometimes, some of these explanations didn't appear to be what we readily understand to be mathematics!
