A couple semesters ago, I took a calculus class with a professor who was…eccentric. He claimed to sleep one hour per night and wrote “Danger: THERE BE DRAGONS!” on every study guide. One time, he gave the class a practice problem that required us to imagine that we had been kidnapped, trapped in the trunk of a car, and had to figure out how far we were from our starting point based on the bumps in the road.
