On the first day of school, the professor asked them to solve a problem: there was a beaker on the table, the cup filled with water, a small hole in the wall of the cup a little lower than the surface of the water, and the water continuously poured out of the hole. Now the problem to be solved is to quickly take measures to stop the water in the cup from flowing outwards. The professor gave four students a day’s thinking time and the next day demonstrated their own ways.
