Come See the Earth Turn,
the Story of Leon Foucault

Written by Lori Mortensen

Illustrated by Raul Allen

Published by Tricycle Press/Random House, Sept. 2010

A sickly child, a poor student, and a medical school dropout, Leon Foucault seemed an unlikely candidate for greatness. But his ingenious experiment—simple, beautiful and stunningly original—changed how we see the world.

Scientists knew that the earth turned on its axis. But how could they prove it? Countless experiments had been tried … and had failed. Then, one historic day in Paris, Leon Foucault gave a magnificent demonstration that offered the proof everyone had been looking for. 

Discover the improbable story of the man behind the famous Foucault's Pendulum.
