Q: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.

A: Negative

Q: The book is a reprint of the biography written by Marie Curie's daughter, Eve Curie in 1937. It is a book which should be read by all - especially aspiring scientists. Marie Curie was the first woman to receive a Ph.D. in France, the first woman to receive a Nobel Prize and the first person to receive two Nobel prizes. The work she accomplished under the most difficult situations for a scientist is truly inspiring. When asked why she and her husband, Pierre Curie did not patent the procedure for extraction and purification of radium, something which would have made them very wealthy, she said "No, It would be contrary to the scientific spirit." How refreshing, since in today's world the first thought of scientists is patenting their discoveries.
