Circle Pi discovery.
Self-discovery of a mathematical constant — measuring it independently rather than being given it — creates an epistemological experience: understanding how humans know what they know. Students who calculate pi from physical measurements develop a relationship with mathematical truth as something discovered, not dictated.
