'The style of the book is quite informal … but the computations appear to be correct, complete and suitable to the scope of the book. … The appendices about mathematical methods can be a good refresher for what was learnt in math courses and will suffice for understanding the mathematics in the different sections.' Giovanni Rastelli, Zentralblatt MATH
