The Invention of Radio

Melvyn Bragg and his guests discuss the invention of radio. In the early 1860s the Scottish physicist James Clerk Maxwell derived four equations which together describe the behaviour of electricity and magnetism. They predicted the existence of a previously unknown phenomenon: electromagnetic waves. These waves were first observed in the early 1880s, and over the next two decades a succession of scientists and engineers built increasingly elaborate devices to produce and detect them. Eventually this gave birth to a new technology: radio. The Italian Guglielmo Marconi is commonly described as the father of radio - but many other figures were involved in its development, and it was not him but a Canadian, Reginald Fessenden, who first succeeded in transmitting speech over the airwaves.With:Simon Schaffer Professor of the History of Science at the University of CambridgeElizabeth Bruton Postdoctoral Researcher at the University of LeedsJohn Liffen Curator of Communications at the Science Museum, LondonProducer: Thomas Morris.

Romance of the Three Kingdoms

Melvyn Bragg and his guests discuss the Romance of the Three Kingdoms, widely regarded as one of the greatest works of Chinese literature. Written 600 years ago, it is an historical novel that tells the story of a tumultuous period in Chinese history, the 2nd and 3rd centuries AD. Partly historical and partly legend, it recounts the fighting and scheming of the feudal lords and the three states which came to power as the Han Dynasty collapsed. The influence of Romance of the Three Kingdoms in East Asia has been likened to that of Homer in the West, and this warfare epic remains popular in China today.With:Frances Wood Former Lead Curator of Chinese Collections at the British LibraryCraig Clunas Professor of the History of Art at the University of OxfordMargaret Hillenbrand University Lecturer in Modern Chinese Literature at the University of Oxford and Fellow of Wadham CollegeProducer: Victoria Brignell.

The Physiocrats

Melvyn Bragg and his guests discuss the Physiocrats, an important group of economic thinkers in eighteenth-century France. The Physiocrats believed that the land was the ultimate source of all wealth, and crucially that markets should not be constrained by governments. Their ideas were important not just to economists but to the course of politics in France. Later they influenced the work of Adam Smith, who called Physiocracy "perhaps the nearest approximation to the truth that has yet been published upon the subject of political economy."With:Richard Whatmore Professor of Intellectual History & the History of Political Thought at the University of SussexJoel Felix Professor of History at the University of ReadingHelen Paul Lecturer in Economics and Economic History at the University of Southampton.Producer: Thomas Morris.

Cosmic Rays

Melvyn Bragg and his guests discuss cosmic rays. In 1912 the physicist Victor Hess discovered that the Earth is under constant bombardment from radiation coming from outside our atmosphere. These so-called cosmic rays have been known to cause damage to satellites and electronic devices on Earth, but most are absorbed by our atmosphere. The study of cosmic rays and their effects has led to major breakthroughs in particle physics. But today physicists are still trying to establish where these highly energetic subatomic particles come from.With:Carolin Crawford Gresham Professor of Astronomy and a member of the Institute of Astronomy at the University of Cambridge Alan Watson Emeritus Professor of Physics at the University of Leeds Tim Greenshaw Professor of Physics at the University of Liverpool.Producer: Thomas Morris.

Icelandic Sagas

Melvyn Bragg and his guests discuss the Icelandic Sagas. First written down in the 13th century, the sagas tell the stories of the Norse settlers of Iceland, who began to arrive on the island in the late 9th century. They contain some of the richest and most extraordinary writing of the Middle Ages, and often depict events known to have happened in the early years of Icelandic history, although there is much debate as to how much of their content is factual and how much imaginative. Full of heroes, feuds and outlaws, with a smattering of ghosts and trolls, the sagas inspired later writers including Sir Walter Scott, William Morris and WH Auden.With:Carolyne Larrington Fellow and Tutor in Medieval English Literature at St John's College, OxfordElizabeth Ashman Rowe University Lecturer in Scandinavian History at the University of CambridgeEmily Lethbridge Post-Doctoral Researcher at the Árni Magnússon Manuscripts Institute in ReykjavíkProducer: Thomas Morris.
