The title refers to a famous mathematics problem: ‘Can dogs do calculus?’”
The problem starts with a university lecturer walking his dog along the beach. He throws a stick into the water but the dog does not run directly
after it into the sea; rather the dog runs part way along the water’s edge before diving in. But the dog doesn’t run so far that it has the shortest distance to swim to the stick.
The lecturer is curious and sets about finding, using calculus, the optimal time for the dog to reach the stick, knowing the dog's running speed is five times quicker than the swimming speed.
He discovers that the dog’s actions match the mathematical theory for the shortest time, not the shortest distance.
