[EX Q]: 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
[EX A]: POS

[EX Q]: Please read this to your child! . I highly recommend this story to all children. I have a young son who is dyslexic--the book was recommended to us by his tutor. But as I was reading this I couldn't help but feel all children would benefit from hearing it. This book is a wonderful example of how children manage to overcome difficulties. It can also help show children to be more compassionate to those who are less fortunate. It is delightful
[EX A]: POS

[EX Q]: disappointed . This book was entertaining, but... there is only one 19-page chapter dedicated to the problem of "inappropriate elimination" (peeing/pooping in the wrong place), even though the author himself describes it as "the number one behavior problem".  He says "No other problem causes so much grief and leads them so often to consider the final solution of euthanasia".  I want to ask the author: given that, don't you think most people are buying the book for that reason and you should have dedicated more time to this topic???  The stories in that chapter did not contain any revelations for me - his examples all had fairly obvious causes and were easy to fix, such as the owner changed the litter box, boyfriend moved in, owner had 2 litter boxes for 6 cats, or the cat is doing it out of anxiety and responds nicely to medication (lucky them).  Throughout the book, I wish he had spent less time making cute anecdotes and more time detailing possible effective interventions
