This book is filled with beautiful illustrations and incomplete explinations. The writer obviously know the material, and was very effective in presenting the information in a completely undigestible manner. In my opinion he should concentrate on trying to teach the information instead of trying to impress the reader with how much he knows...and you DON'T! And how about the type errors...too many to go into. The editor should proof read his work before sending it to press...but then he doesn't really need to because on the 4th page of the book is a disclaimer stating that this book is "AS IS" and that they don't take responsibility for the book's accuracy or completeness. I wouldn't want to be responsible for this book either! Well, that's my personal opinion...take it for what you will.Very Disappointed.
