One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem, while the student claimed a perfect score. I was elected as their arbiter（仲裁人）. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer（气压计）. ”The student had answered; "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of it is the height of the building.”
