Il problema spesso sono i libri, \u00e8 per\u00f2 anche vero che \u00e8 difficile fare divulgazione credibile quando si parla di matematica. A questo proposito il titolo del libro di <strong>David Blatner<\/strong> <strong>\u201cLe Gioie del PIGRECO\u201d<\/strong> (Garzanti) promette molto bene.<span style=\"mso-spacerun: yes\">\u00a0 <\/span><br \/>Il pi greco \u00e8 il rapporto tra la circonferenza di un cerchio e il suo diametro. Ma il calcolo dei decimali di questo numero \u00e8 forse l\u2019unico problema che accomuna i matematici antichi e quelli moderni, i primi architetti e i progettisti dei moderni computer, perch\u00e9 nessun numero ha suscitato tanti interrogativi e misteri, tanto interesse e margine di errore. Anche perch\u00e9 questo calcolo \u00e8 un compito infinito, cos\u00ec come sono infiniti i piaceri numerici e le curiosit\u00e0 matematiche che offre David Blatner nel suo libro. Una panoramica che ripercorre l\u2019intera storia dell\u2019umanit\u00e0, dagli antichi egizi alla Bibbia, da Archimede a Leonardo, da Umberto Eco e Carl Sagan ai fratelli Chudnovski, gli ultimi eroi che ne hanno calcolato oltre otto miliardi di decimali con un supercalcolatore fatto in casa. Informatissimo, pieno di sorprese, spesso divertente, affollato di menti geniali e maniaci senza rimedio, Le gioie del pi greco \u00e8 l\u2019affettuoso omaggio a questo piccolo grande numero, e offre la clamorosa conferma che la matematica pu\u00f2 essere molto ma molto divertente.<span style=\"COLOR: #666666\">\u00a0<\/span><\/span><span style=\"FONT-FAMILY: Arial; mso-fareast-font-family:
