Il libro è un tentativo di esplorare quella facoltà innata che è la capacità di calcolare. Per compiere la sua indagine l'autore non sceglie però la via teorica: preferisce raccontare la storia stupefacente delle tecniche di calcolo. È una storia piena di sorprese e di personaggi come gli "idiot savants", persone prive di qualsiasi attitudine specifica, ma capaci di compiere operazioni e dimostrazioni prodigiose.
As a popular description of work to establish the kinds of mathematical thought which seem to be innate in the brain from birth (basic principles which underly counting and simple arithmetic), there is some interesting material in this book. It is let down by being extremely repetitive, with some explanations seeming to appear in every chapter. I would also like to know more about the differences between the ways that professional mathematicians think as compared to the norm; most of the coverage here is repetition of well known stories such as the life of Ramanujan. Could have been much better.
Interesting research about number systems and the different representations of number within the world and how that is conceptualized within the brain. It becomes a bit lifeless however when you have to read it quickly and use it for essays. Best chapter is definitely "Home, School and Street Mathematics". I recommend this to anyone interested in maths/education.
The fact that our brain was loaded with mathematical approach in analyzing our surrounding. There's nothing to fear about math anyway.. the truth is do we know the concept!...
