Input: Consider Input: Excellent introduction to the field for physicists . Perhaps the best feature of this book is that it aims to convey the theory of Lie algebras and Lie groups to physicists. In doing so, the author is careful to give a very simplistic approach so that one not familiar with the subject can understand it. Not to say that the book is elementary, since it builds rapidly into the far more interesting aspects of Lie Groups. A very good read

Output: POS

Input: Consider Input: Too much . This book places too much emphasis on spending money instead of eating...well if we all had money to burn that would be a wonderful lifestyle. Read "The Fat Fallacy" instead, it provides much more practical information
Output: NEG
