Ket : I f you want a good measurement problem, watch the movie Die Hard with a Vengeance. In the movie, the characters played by Bruce Willis and Samuel L. Jackson are trying to stop the bad guys and find themselves in a crowded park with a five-gallon plastic jug, a three-gallon plastic jug, a water fountain, and a big bomb attached to a scale. To defuse the bomb, they must place four gallons of water (with no more than a few ounces error) on the scale within a certain amount of time; otherwise, everyone dies. They solve the problem, of course, but only after realizing that the jugs and scale are not enough and that they need a precise, logical process to arrive at the necessary measurement. The scene is great. It has a measurement challenge, an acceptable margin of error, and unacceptable consequences should the measurement fail. And in the end, the problem is much less about metrics (volume and weight in this case) and much more about the process of measuring in support of a decision (whether or not to put the jug on the scale and risk going boom).
