3 x 1 hr series for BBC4 presented by Marcus du Sautoy

Programme 2 – Mass and Moles

Measurement is a story that’s as old as mankind. It’s a subject that we’ve grappled with since cave dwelling times when we counted on our knuckles, and continues to perplex the greatest minds in modern science. Packed with cutting-edge science, amusing anecdotes from history and jaw-dropping examples from the modern world, this is the story of our journey from painting caves to the exploration of outer space.

With experiments both modern and ancient, the series will explain how we developed the seven international units of measurement for time, length, mass, brightness, current, temperature and moles (the measurement of atoms). And how these seven have shaped the course of history, science and civilization.
