Albert Einstein
Albert was a quiet child who spent much of his time alone. When Albert was five years old, his father gave him a compass. The child was filled with wonder when he discovered that the compass needle always pointed in the same direction—to the north. He asked his father and his uncle what caused the needle to move. Their answers about magnetism and gravity were difficult for the boy to understand. Yet he spent a lot of time thinking about them. He said later that he felt something hidden had to be behind things.
