Title: The real "as the world turns"
Review: Years ago when I lived in California, my father used to take me to San Francisco, and one of the things we loved to see was the Foucault Pendulum in the Golden Gate Park. I didn't realize until I read this book the real significance of what the inventor had done. Prior to this invention, there was doubt in the religious world that the earth turned on its axis and there was a belief that the Universe moved around the earth. He showed by the use of a pendulum that hung from the ceiling and made marks in sand that the earth was indeed moving. Anyone who is interested in science, and even those who are not, should enjoy the story of this very inventive man.
