Heat

Melvyn Bragg and guests discuss the history of scientific ideas about heat. As anyone who’s ever burnt their hand will testify – heat is a pretty commonplace concept. Cups of coffee cool down, microwaves reheat them, water boils at 100 degrees and freezes on cold winter nights.Behind the everyday experience of hot things lies a complex story of ideas spread across Paris, Manchester and particularly Glasgow. It’s a story of brewing vats and steam engines, of fridges, thermometers and the heat death of the universe. But most importantly, it was the understanding and harnessing of heat that helped make the modern world of industry, engineering and technology.With Simon Schaffer, Professor of History of Science at the University of Cambridge and Fellow of Darwin College; Hasok Chang, Professor of Philosophy of Science at University College London and Joanna Haigh, Professor of Atmospheric Physics at Imperial College London

The Fire of London

Melvyn Bragg and guests discuss The Great Fire of London which destroyed up to a third of the city in 1666. Samuel Pepys described the scene in his diary:“all over the Thames, with one's face in the wind, you were almost burned with a shower of firedrops…and in corners and upon steeples, and between churches and houses, as far as we could see up the hill of the City, we saw the fire …It made me weep to see it.”The London that rose from the ashes was a visible manifestation of ideas; of the politics, religion, economics and science of the heady Restoration period. Christopher Wren, of course, but also Robert Hooke, The Royal Society, St Paul’s Cathedral, the Restoration court of Charles II and, inevitably, building regulations. With Lisa Jardine, Centenary Professor of Renaissance Studies at Queen Mary, University of London; Vanessa Harding, Reader in London History at Birkbeck, University of London and Jonathan Sawday, Professor of English Studies at the University of Strathclyde
