Wow! That is time in my life I won't get back...I'm trying to be fair with my 3 star rating. I really would give it 1 star but it is my fault for choosing it. If you are in to this science stuff then you probably will love it! It has great reviews. I guess I expected more stories about the discovery of the elements, but what I got was about 20% stories (which were mostly really interesting!) and 80% science which was, for me, mindnumbingly boring. Avery kept telling me to just stop reading it but I didn't want to be a quitter...I thought I might miss something great. And one of the stories at the end WAS really interesting, about the official kilogram kept in Paris. Anyway, if you like reading about electrons, fusion, heavy water, etc...this is for you.
