My thoughts

I think this will be the book that I will go back to again and again. There were so many interesting facts to learn, and I enjoyed reading about how various scientists discovered new information that often surprised them. I liked reading about William Herschel's discovery of the planet Uranus in 1781 and how he wanted to name it after King George III (Georgium Sidus). I also liked learning about prehistoric guinea pigs the size of cows.
