One day a boy named Theo is called into the living room by his parents to meet "the most famous man alive." He's very nervous, but finds the Professor to be kind and gentle. When they go out for a sail on Theo's small boat, the Professor unexpectedly loses his compass overboard. The compass was a cherished gift from Einstein's father when he himself was a young boy. Fortunately, Theo manages to save the day--along with the compass! The author's husband was a personal friend of Albert Einstein's, and though fictional, this story is based on events in Einstein's life. The lovely watercolors capture the meeting between a young boy and the wild-haired physicist. Their simple conversations provide insight into the mysteries of physics that inspired Einstein's lifelong quest to understand and explain the forces of nature.
