“Dr. Seethaler has written an excellent book for any interested student of science. She answers great questions about the world around us in this fascinating book. As a high school science teacher, I encounter many of these from my own students. I would highly recommend this book for anyone who has pondered questions starting with ‘how,’ ‘what,’ or ‘why.’”
–Ernest James Lo, Science Teacher, Woodside High School, Woodside, CA
