Hello all. I'm looking for a book recommendation for my mom. She is Catholic, and I'm not trying to convert her to atheism, but I think she might enjoy learning a little more about basic science. I don't think she got much of an education on science at her Catholic schools all those years ago, and yesterday while playing a trivia board game with her, she was shocked and amazed to learn about the length of the human small intestine. I'm looking for a book for adults that presents basic scientific concepts in an interesting and readable way and that stays away from religion. Perhaps something that focuses more on biology. Any ideas? Thanks!
