Excerpt:
On an ordinary day, Galileo encounters Massimo dropping food from a bridge to his uncle passing below in his boat. He is surprised to realize that both the bread and the cheese hit the boat simultaneously, even though they differ in weight. Galileo takes an interest in Massimo's cleverness, and together, in a series of experiments, the two investigate the science of motion and demonstrate their new theory (that every object falls at the same speed) to the people of the town. Even though Massimo is fictitious, the story demonstrates one of Galileo's most famous experiments and explains to young readers one of the basic concepts of physics.
