Does Your Knowledge Measure Up?

Several parts of last night's class left me thinking about standards: those by which we judge ourselves and others; those by which we measure the world we inhabit.  One discussion touched on the potential objectivity of the measure "one foot."  My mind wandered to bureaus of weights and measures and the efforts they put forth to maintain constants.  For Sunday night, 9/28, at 9:30, please listen to this podcast, then write a post in which you share two knowledge questions directly related to the piece, one addressing History as an AoK, the other addressing Natural Sciences.  For each KQ, offer a related real world situation from your own experiences.  As you compose, keep in mind our discussion of hypothetical situations and their pitfalls.
