\"[copertina]\" Libri di matematica ricreativa ce ne sono tanti, per\u00f2 \u00e8 sempre possibile trovarne qualcuno di cui non si era sentito parlare. Almeno per me \u00e8 stato il caso di questo libro (Keith Ball, Strange Curves, Counting Rabbits, and other Mathematical Explorations<\/em><\/a>, Princeton University Press 2007 [2003], pag. 251, $ 23,95, ISBN 978-0-691-12797-2). Ball l’ha scritto a partire da un ciclo di conferenze che aveva preparato su temi matematici non trattati solitamente a scuola. Quello che ho trovato interessante \u00e8 che, nonostante i temi siano abbastanza standard, la spiegazione si sposta su propriet\u00e0 non certo note, tipo la trattazione matriciale dei numeri di Fibonacci oppure le procedure esplicite per costruire le curve di Peano. In pratica, insomma, ci si muove tra la matematica ricreativa e quella pi\u00f9 seria, secondo la scuola che afferma che tutta la matematica \u00e8 sempre matematica, e che certe divisioni sono artificiali. Intendiamoci, la trattazione non \u00e8 esattamente elementare, e non lo consiglierei come libro introduttivo; per\u00f2 sono sicuro che chi ha gi\u00e0 un background matematico lo trover\u00e0 interessante.<\/div>\n","protected":false},"excerpt":{"rendered":"
