I really liked this book because it was very informational and I love science. Sometimes it was confusing but that's only because it had a lot of big huge sciency terms. I really liked the little illustrations it had, and how much the book covered. I want to read more books by this author because he seems to know what he's talking about. This book could be really boring to people who don't like science or don't like nonfiction and getting really in depth with a book. I personally loved it because it made me feel like ten times smarter, and well, science is AWESOME.
