The history of ideas discussed by Melvyn Bragg and guests including Philosophy, science, literature, religion and the influence these ideas have on us today.
Melvyn Bragg and his guests discuss the measurement of time. Early civilisations used the movements of heavenly bodies to tell the time, then mechanical clocks emerged in Europe in the medieval period. 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.

Melvyn is joined by Marcus du Sautoy, Professor of Mathematics at the University of Oxford; Colva Roney-Dougal, Senior Lecturer in Pure Mathematics at the University of St Andrews; and Timothy Gowers, Royal Society Research Professor in Mathematics at the University of Cambridge.

Alice Bell argues that better engagement by scientists, rather than lessons in ‘scientific literacy’, is the solution to the lack of public understanding of science. She is frustrated how often this apparent panacea is rolled out as the solution to the problem. But on some controversial subjects the scientific evidence does not point in a single direction, she says. More than that, the specific bit of science needed to understand the subject at hand varies from issue to issue.
