IOT with Melvyn Bragg
Measurement of Time 29 Mar 12
Thu, 29 Mar 12

For hundreds of years clocks were inaccurate but now atomic clocks are capable of keeping time to a second in 15 million years. Melvyn Bragg is joined by Kristen Lippincott, Former Director of the Royal Observatory, Greenwich; Jim Bennett, Director of the Museum of the History of Science at the University of Oxford and Jonathan Betts, Senior Curator of Horology at the Royal Observatory, Greenwich.
