Why Do Buses Come in Threes? is a delightfully entertaining ride for anyone wanting to remind themselvesâor discover for the first timeâthat math is relevant to almost everything we do. Buses that bunch, identical potato chips, and slicing a cake evenly for an odd number of guests all have their links to intriguing mathematical problems. With great humor and a genuine love for the subject, the authors present the solutions to such conundrums as how fast one should run in the rain to keep dry and who was the greatest sportsman statistically.
Discover the mathematical explanations for the strange coincidence of two Presidents dying on July 4, the uncanny "accuracy" of horoscopes, the number of petals on a flower and seeds in an apple, and other not-so-coincidental coincidences. Eastaway and Wyndham also reveal how television ratings work, which numbers are more likely to be big winners in the lottery, and why bad things, just like buses, always seem to happen in threes. It's a fascinating journey through the logic of life where Newton's laws explain bar fights, exploding rabbit populations, and why showers always run either too hot or too cold. For the kids, the authors have devoted an entire chapter to tricks that entertain, teach, and baffle children with the magical properties of numbers. So climb aboard, take a ride, and discover the hidden mathematical code to some of life's greatest (and most irritating) questions.
