It's amazing the amount of work that mathematicians have to do, to solve the problems of everyday life. This book explains the numbers behind the weather, bookmakers and dating agencies. Amongst all the calculations, it is comforting to know that often the lateral-thinking solutions are the best. For instance, lift-engineers have to know a lot of theory to keep their customers waiting for the least time, but the best solution was to put mirrors in front of the lifts, so that people didn't realise how long they were waiting as they were too busy preening themselves! Well worth buying for the clever inside information alone.
