Precision: The Measure of All Things

Director: Mike Cunliffe
UK, 2013, 3x60', color 
English with Turkish subtitles 

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. 

Epsiode 1: Time and Distance

Professor Marcus du Sautoy tells the story of the metre and the second - how an astonishing journey across revolutionary France gave birth to the metre, and how scientists today are continuing to redefine the measurement of time and length, with extraordinary results. 

Episode 2: Mass and Moles

Deep underground in a vault beneath Paris lives the most important lump of metal in the world - Le Grand K. Created in the 19th century, it's the world's master kilogramme, the weight on which every other weight is based. But there is a problem with Le Grand K - it is losing weight. Professor Marcus du Sautoy explores the history of this strange object and the astonishing modern day race to replace it.

Episode 3: Light, Heat and Electricity

From lightning bolts and watt engines to electromagnetic waves and single electrons, Professor Marcus du Sautoy continues his journey into the world of measurement as he reveals how we came to measure and harness the power of heat, light and electricity. It's a journey that has involved the greatest minds in science and, today, is getting down to the very building blocks of atoms.
