Title: Wonderful writing style and very readable Review: This book assumes the reader knows nothing about mathematics and walks the reader through some reasonably complicated mathematical properties and history to make the subject quite enjoyable. The book can be summarized as a great following of mathematical and cultural history, with the focus, of course, on the ways that mathemeticians through the centuries have worked towards the final solving of Fermat's Last Puzzle.

Title: Not effective Review: I got this (and the spray) for my son's 1-year-old rescue Boxer who has severe separation anxiety. Neither product was effective with THIS dog. I know other people who got much better results and that's why I wanted to try it out. The collar is difficult to fit properly and if it doesn't have continuous, direct contact with the body, the pheromone can't be absorbed into the skin. Then try to adjust the collar ... no way! It was worth a try but certainly didn't help the situation at all. My son continues behavior modification strategies - slow, but sure - and he's making progress. I just wish this product could have helped it along. Is the review positive or negative?
