‘The Last Artifact’ Brings Metrology to TV

Remember that documentary you saw thatfinallyexplained metrology and why measurements are critical to practically every aspect of modern life? Yeah, neither do I. Probably because that documentary doesn’t exist … Or does it? The Last Artifact, a new one-hour film that PBS stations are planning to broadcast starting this month, aims to fill that cinematic void by bringing metrology to the people
