This book ought to deserve 5 stars, but it's full of sentences like this:
"The elements are conveniently set out in a table called the periodic table---I won't go into why it's called that, although it's interesting."
It's infuriating that Dawkins can't make science simple without mutilating the details. This is presumably a book for children, and I can't see how this approach is supposed to get them excited to learn more, when Dawkins continuously refuses to complete his explanations.
