Good book rather spoiled by gloss paper. I like paper to be matt it makes it more pleasant to make notes on. I like the feel of Matt paper. I would be reluctant to buy any more books in that range because of the unpleasant texture of the pages. I have no issue with the contents at all.
It was a useful tool to learn about Galileo for myself so that I can teach children. It's format is very adult like. I completed some of the activities and adapted them so that the children could access the book
