Review title: Our Battlecry: "Arfken!" Product review: Throughout the past year, our common battlecry in my classical mechanics and mathematical physics courses was "Arfken!"... usually followed by "Maple!" (a powerful math program). I am not as qualified to offer a comprehensive review of this book as the professors and graduate students whose words also appear here. However, I know that someday I will be and I know that Arfken was one o the best guides that I had on the trip. 'Nuff said.

Review title: This book is not what it seems Product review: I ordered this book along with Down the Rabbit Hole. All the promotions would lead one to believe that I would learn more about the movie and the information in it. The author is on a mission to discredit everything about the movie and the people and organizations associated with it, including me, the viewer.This book is not worth the paper it is printed on. I am disappointed that someone would take the time to write it. The author says she is amazed that such a movie would be made. The movie has much more credibility than this book. She has used the Bleep's populatity to promote and sell her useless book. Any good review has to be planted.

Review title: The Vaughan Brothers - Family Style Product review: As a Stevie Ray Vaughan fan and an owner of this CD I would like to tell anybody who Likes Stevie or Jimmie (- yes I am a fan of his as well!!)That this CD is worth getting. A lot of people have commented on Stevie "Down Playing" on this album, but I have noticed that on live alive and other recordings that Jimmie appears in Stevie seems to down play on those recordings as well (Listen to "Willy the wimp" on live alive). Also I am sure that this was the brothers little pet project thats why its not so much of a hard core blues album. My tip is buy and enjoy something from the brothers thats a little different!!!

Product review: It's too bad McLintock managed to get this published.The author obviously has a personal vendetta. Her inaccurate portrail of Peggy Claude-Pierre, David Harris and the Montreux Clinic is a disgrace!I personally know three women who received treatment at Montreux. Each one credits Claude-Pierre's methods with saving their lives. Her loving, supportive intensive treatment should be an inspiration. To print such lies just continues to cause unneccessary suffering to those who will not have the benefit of legitimate help.Shame on McLintock!
