I libri sul rapporto aureo, nel bene e nel male, sono solitamente pieni di fattoidi tendenti al new age, anche quando l’autore vuole spiegare perch\u00e9 quelle associazioni sono tirate per i capelli e non hanno nessun fondamento reale. Ben venga quindi questo libro, dove Dunlap si limita a considerazioni puramente matematiche sul rapporto aureo (e sui numeri di Fibonacci e di Lucas, che sono strettamente collegati ad esso). \u00c8 un po’ buffo che Dunlap usi il “vecchio” simbolo τ per il numero, dopo che gi\u00e0 da un paio di decenni Martin Gardner aveva sdoganato il ϕ (pi\u00f9 per Fibonacci che per Fidia, secondo me), ma non \u00e8 un problema. Peccato per qualche refuso che rende pi\u00f9 complicata la lettura, come quando un ottaedro \u00e8 diventato un tetraedro.<\/p>\n
