For every mathematician working with complex physic tests and a limited budget, this book can be useful. Unfortunately I am just a modeler of simple discrete event simulations, so for me this book was not very useful. Except for the first chapter that tells a little about different simulation methods, the book mainly contains very technical examples of interesting physical experiments. Through the whole of the book, lots of functions are included, which seem generic for any kind of proof with atoms or light differentiation. But in my opinion, the book does not add any value to persons that want to know how they can improve their tests using computer simulation in general.

This alleged biography of Ella Fitzgerald is seriously flawed and not recommended. At its most basic, the book is simply not a serious biography written in a professional manner. For example, the author CONSTANTLY interupts the narrative to give the reader HIS opinions of each and every song she sings, her weight and even her wigs. Even the captions to the photos are annoying ("Still hiding her figure for Verve"..."Oh those awful wigs") This is not acceptable or serious writing for a biography. He also seemingly attempts to convince the reader that he knew Ella personally, sometimes referring to her (annoyingly) as "Miss Fitz." Another complaint: the author talks knowingly about live recorded concert albums leading the reader to believe he has some inside knowlege of a concert, when in reality he is simply relating what is on the actual album for everyone to hear. He also refers to others he supposedly interviewed by their first names ("Keeter" Betts, "Danny" Kaye). Was he really on a first name basis with these people? Of course, we don't know who he interviewed, or when he interviewed them, because there aren't any notes in the book to prove it. If you want a serious bio of the great singer, instead of this thing, I recommend the much-respected "Ella Fitzgerald" by Stuart Nicholson.
