We all know the earth is round. But HOW do we know? Join intrepid young scientist-adventurer Joulia Copernicus as she takes readers on a historical journey through time and space. From jumping on board Columbus's ship to planet-hopping in the outer reaches of our solar system, Joulia explains with humor and wit the ins and outs of how we learned that the earth is round.
