I thought that would be a "normal" book, but this book is a collection of published articles Nur. But a successful collection. The book, or rather the articles in the book, extreem technically and adjoin unreadable if you do not know the terminology. I myself am not a skilled worker and find this book almost impenetrable, but not regret the purchase because I still many "pearls of whiteness" in it find.
One should know what you are buying before you order it but.
