Aha! Gotcha: Aha! Insight

Rate this book
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.'

La MAA (Mathematical Association of America) sta facendo un gran lavoro insieme a Martin Gardner, recuperando tutta la sterminata produzione di giochi matematici portata avanti nei decenni dal nostro eroe. Dopo il CD che contiene la versione in PDF di tutte le raccolte degli articoli nella rubrica "Mathematical Games" sullo Scientific American ora è la volta della ristampa in un unico volume di due raccolte di giochini le cui soluzioni si possono trovare senza dover fare chissà quali conti complicati. Personalmente ho trovato il primo dei due volumi, soprattutto nella prima parte, piuttosto semplicistico e forse più adatto a un ragazzino, anche se poi il libro si riscatta con la parte sulla probabilità. Molto più apprezzabile il secondo testo, con problemini e indovinelli davvero simpatici. Una piacevole lettura, anche se purtroppo piuttosto costosa: le case editrici matematiche tendono ad avere prezzi inaccessibili.
