The KT Boundary

Melvyn Bragg and guests discuss the KT Boundary. Across the entire planet, where it hasn't been eroded or destroyed in land movements, there is a thin grey line. In Italy it is 1 cm thick, in America it stretches to three centimetres, but it is all the same thin grey line laid into the rock some 65 million years ago and it bears witness to a cataclysmic event experienced only once in Earth's history. It is called the KT Boundary and geologists believe it is the clue to the death of the dinosaurs and the ultimate reason why mammals and humans inherited the Earth.But exactly what did happen 65 million years ago? How was this extraordinary line created across the Earth and does it really hold the key to the death of the dinosaurs?With Simon Kelley, Head of Department in the Department of Earth Sciences, Open University, Jane Francis, Professor of Palaeoclimatology, University of Leeds; Mike Benton, Professor of Vertebrate Palaeontology in the Department of Earth Sciences, University of Bristol.

The Han Synthesis

The Han Synthesis

Melvyn Bragg and guests discuss the Han Synthesis philosophies of China. In The Analects the Chinese sage Confucius says of statecraft: "He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn to it".Confucianism had been all but outlawed under the Chin Emperor, but in 206 BC the Han dynasty came to power and held sway for over 400 years. They brought Confucian thought to the heart of government, his favourite books became set texts for the world's first civil service exam and in a grand intellectual project 'The Great Tao' was combined with 'The Five Phases' and with the Yin and the Yang.Who were the Han? How did they bring these strands of thought together into the great founding moment of Chinese culture? And what drove them to their extraordinary intellectual task?With Christopher Cullen, Director of the Needham Research Institute; Carol Michaelson, Assistant Keeper of Chinese Art in the Department of Asia at the British Museum; Roel Sterckx, Lecturer in Chinese Studies at the University of Cambridge.

Sartre

Sartre

Melvyn Bragg and guests discuss Jean-Paul Sartre, the French novelist, playwright, and philosopher who became the king of intellectual Paris and a focus of post war politics and morals. Sartre's own life was coloured by jazz, affairs, Simone de Beauvoir and the intellectual camaraderie of Left Bank cafes. He maintained an extraordinary output of plays, novels, biographies, and philosophical treatises as well as membership of the communist party and a role in many political controversies. He produced some wonderful statements: "my heart is on the left, like everyone else's", and "a human person is what he is not, not what he is", and, most famously "we are condemned to be free". Melvyn Bragg and guests discuss how Sartre's novels and plays express his ideas and what light Sartre's life brings to bear on his philosophy and his philosphy on his life. With Jonathan Rée, philosopher and historia; Benedict O'Donohoe, Principal Lecturer in French at the University of the West of England and Secretary of the UK Society for Sartrean Studies; Christina Howells, Professor of French at the University of Oxford and a Fellow of Wadham College.

Politeness

Politeness

Melvyn Bragg and guests discuss the idea of Politeness. A new idea that stalked the land at the start of the eighteenth century in Britain, Politeness soon acquired a philosophy, a literature and even a society devoted to its thrall. It may seem to represent the very opposite now, but at that time, when Queen Anne was on the throne and The Spectator was in the coffee houses, politeness was part of a radical social revolution.How did the idea of politeness challenge the accepted norms of behaviour? How did a notion of how to behave affect the great wealth of eighteenth century culture? With Amanda Vickery, Reader in History at Royal Holloway, University of London; David Wootton, Professor of History at the University of York; John Mullan, Senior Lecturer in English at University College London.

The Origins of Life

The Origins of Life

Melvyn Bragg and guests discuss the emergence of the world’s first organic matter nearly four billion years ago. Scientists have named 1.5 million species of living organism on the land, in the skies and in the oceans of planet Earth and a new one is classified every day.  Estimates of how many species remain to be discovered vary wildly, but science accepts one categorical point – all living matter on our planet, from the nematode to the elephant, from the bacterium to the blue whale, is derived from a single common ancestor. What was that ancestor?  Did it really emerge from a ‘primordial soup’? And what, in the explanation of evolutionary science, provided the catalyst to start turning the cycle of life?With Richard Dawkins, Charles Simonyi Professor of the Public Understanding of Science at Oxford University; Richard Corfield, Visiting Senior Lecturer at the Centre for Earth, Planetary, Space and Astronomical Research at the Open University; Linda Partridge, Biology and Biotechnology Research Council Professor at University College London.

Agincourt

Agincourt

Melvyn Bragg and guests discuss the Battle of Agincourt."Owre kynge went forth to Normandy, With grace and myyt of chivalry; The God for hym wrouyt marvelously, Wherefore Englonde may calle, and cry Deo gratias: Deo gratias redde pro victoria." The great victory was Agincourt as described in the Agincourt Carol, when the 'happy few' of the English army of King Henry V vanquished the French forces on St Crispin's Day 1415. It is a battle that has resounded through the centuries and has been used by so many to mean so much. But how important was the battle in the strategic struggles of the time? What were the pressures at home that drove Henry's march through France? And what is the cultural legacy of Agincourt? With Anne Curry, Professor of Medieval History at Southampton University; Michael Jones, medieval historian and writer; John Watts, Fellow and Tutor in Modern History at Corpus Christie College, Oxford.

The Odyssey

The Odyssey

Melvyn Bragg and guests discuss The Odyssey by Homer, often claimed as the great founding work of Western Literature. It's an epic that has entertained its audience for nearly three thousand years: It has shipwrecks, Cyclops, brave heroes and seductive sex goddesses. But it’s also got revenge, true love and existential angst. The story follows on from Homer's Iliad, and tells of the Greek hero Odysseus and his long attempt to get home to Ithaca after the Trojan War. Melvyn Bragg and guests discuss what has given the Odyssey such a fundamental position in the history of western ideas, what are the meanings behind the trials and tribulations that befall Odysseus and how the Odyssey was composed and by whom. With Simon Goldhill, Professor of Greek at King's College, Cambridge; Edith Hall, Leverhulme Professor of Greek Cultural History at Durham University; Oliver Taplin, Classics Scholar and Translator at Oxford University.

Pi

Pi

Melvyn Bragg and guests discuss the history of the most detailed number in nature. In the Bible's description of Solomon's temple it comes out as three, Archimedes calculated it to the equivalent of 14 decimal places and today's super computers have defined it with an extraordinary degree of accuracy to its first 1.4 trillion digits. It is the longest number in nature and we only need its first 32 figures to calculate the size of the known universe within the accuracy of one proton. We are talking about Pi, 3.14159 etc, the number which describes the ratio of a circle's diameter to its circumference. How has something so commonplace in nature been such a challenge for maths? And what does the oddly ubiquitous nature of Pi tell us about the hidden complexities of our world? With Robert Kaplan, co-founder of the Maths Circle at Harvard University, Eleanor Robson, Lecturer in the Department of History and Philosophy of Science at Cambridge University; and Ian Stewart, Professor of Mathematics at the University of Warwick.

Washington and the American Revolution

Washington and the American Revolution

Melvyn Bragg and guests discuss the first President of the US, George Washington, and the people and ideas that caused the American Revolution. In 1774 a tobacco farmer from Virginia with nice manners and a quiet lifestyle was moved to put himself forward as the military leader of the most massive rebellion the British Empire had ever suffered. George Washington had been a stout upholder of the status quo, regularly lending money to his ne’r-do-well neighbour simply to keep him in the plantation to which he had become accustomed. He even wrote a book on how to behave properly in polite society.What drove mild mannered George Washington to revolution? Washington may have been a moral man, but by anyone’s account he was no scholar, so who provided the intellectual inspiration behind that grandest of Enlightenment documents, the American Constitution. With Carol Berkin, Professor of History at The City University of New York; Simon Middleton, Lecturer in American History at the University of East Anglia; and Colin Bonwick, Professor Emeritus in American History at Keele University.
