Precision: The Measure of All Things

Oxford University professor Marcus du Sautoy (The Secret Rules of Modern Living: Algorithms) traces mankind's journey from counting on our knuckles to developing today's seven international units of measurement: time, length, mass, brightness, current, temperature and moles (the measurement of atoms).Packed with cutting-edge science, amusing historical anecdotes and experiments from both ancient and modern times, the documentary explores how systems of measurement have shaped the course of human history.
