A physics story about electricity

"The Story of Ampere - The Man Who Chased the Carriage and Solved the Problem"

When Ampere was still a child, he showed good mathematical ability and became a famous mathematician at the age of 12. The mathematician Lagrange was his teacher and he published a mathematical paper when he was 13 years old. The valuable thing about Ampere is that he is good at thinking. Once, while walking on the street and thinking, he suddenly came up with an electrical equation and was anxious to list it out. There happened to be a carriage parked in front of him, so he used the carriage's carriage as a blackboard. He followed the carriage as it went. He walked faster and faster, and did not stop until he could no longer catch up with the carriage. At this time, many people on the street were laughing at his abnormal behavior.
