Review title: A critical analysis Product review: In reality, I think SOME of us have learned so much about Pokemon already that we don't need this book. I also think that the author isn't asking the right kids for his books. For example, in the first book, there was about 5 pages citing kids arguing on which Pokemon is the most "powerfulest".The question on whether this book is helpful or not is completely based on how much the reader actually knows already. In my opinion, his view towards Pokemon is not a strategical view, and if it is, it's not enough.

Review title: French & Saunders... tres magnifique! Product review: For true lovers of British wit, French & Saunders are always the source of the real belly laugh... no canned laughter here masking inadequate writing and acting! This show fulfills all of one's comedic expectations, and if you can control your laughing you may just catch half of the jokes!

Product review: I had seen this book in a bookstore over 15 years ago and regretted that I did not buy it at that time. Now that I have it, I am very disappointed. First of all, the print for the examples is very very small. The book is more of a summary of methods than any details of the methods themselves. There is no systematic development of the mathematical theory for these methods. This reinforces the worst aspects of books on aymptotic methods and perturbation theory: it's all just a bunch of random trial and error jibbrish!The authors tried to pile in a lot of methods into the book without detailed explanations. I find it hard to believe that a scientist or engineer would get a lot out of this book. As a mathematician, I found it lacking in any significant mathematical meaning and purpose. I would recommend Nayfeh's book on peturbation methods instead.

Review title: Keeps you on the edge of your seat! Product review: Unless you are one that always knows the end to every movie from the very start, you will be "in the dark" about the ending of this story till the very end! You can tell Sandra Brown really does her research for each book. Well done!
