aha! A two volume collection: aha! Gotcha aha! Insight (Spectrum)

Previously published separately, the two books aha! Gotcha and aha! Insight are here combined as a single volume. The aha! books, as they are referred to by fans of Martin Gardner, contain 144 wonderful puzzles from the reigning king of recreational mathematics. In this combined volume, you will find puzzles ranging over geometry, logic, probability, statistics, number, time, combinatorics, and word play. Gardner calls these puzzles aha! problems, that 'seem difficult, and indeed are difficult if you go about trying to solve them in traditional ways. But if you can free your mind from standard problem solving techniques, you may be receptive to an aha! reaction that leads immediately to a solution. Don't be discouraged if, at first, you have difficulty with these problems. After a while you will begin to catch the spirit of offbeat, nonlinear thinking, and you may be surprised to find your aha! ability improving.'

Martin Gardner published his first book in 1935. Since then he has published more than 60 books, most of them about mathematics and science, but also philosophy and literature. He has charmed readers of all ages with his mathematical insights and his sense of fun. He has written one novel, The Flight of Peter Fromm and a collection of short stories, The No-Sided Professor. He wrote the popular Mathematical Games column for Scientific American for 25 years. The entire collection of all of Martin Gardner's Scientific American columns, Martin Gardner's Mathematical Games, are available form the MAA, on one CD in a searchable database. This CD contains all 15 of the published books that contained these columns.
