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.

Yeats and Irish Politics

Yeats and Irish Politics

Melvyn Bragg and guests discuss the poet W.B. Yeats and Irish politics. Yeats lived through a period of great change in Ireland from the collapse of the home rule bill through to the Easter Rising of 1916 and the partitioning of the country. In May 1916, 15 men were shot by the British government. They were the leaders of the Easter Rising – a doomed attempt to overthrow British rule in Ireland - and they were commemorated by W.B. Yeats in a poem called Easter 1916. It ends with the following lines: MacDonagh and MacBrideAnd Connolly and PearseNow and in time to be,Wherever green is worn,Are changed, changed utterly:A terrible beauty is born.Yeats lived through decades of turbulence in Ireland. He saw the suspension of home rule, civil war and the division of the country, but how did the politics of the age imprint themselves on his poetry, what was the nature of Yeats’ own nationalism, and what did he mean by that most famous of phrases ‘a terrible beauty is born’?With Roy Foster, Carroll Professor of Irish History at Oxford University and Fellow of Hertford College, Oxford; Fran Brearton, Reader in English at Queen’s University, Belfast and Assistant Director of the Seamus Heaney Centre for Poetry; Warwick Gould, Director of the Institute of English Studies in the School of Advanced Study, University of London

The Norman Yoke

The Norman Yoke

Melvyn Bragg and guests discuss ‘the Norman Yoke’ – the idea that the Battle of Hastings sparked years of cruel oppression for the Anglo Saxons by a Norman ruling class. ‘Norman saw on English oak,On English neck a Norman yoke;Norman spoon in English dish,And England ruled as Normans wish.’Taken from Sir Walter Scott’s novel ‘Ivanhoe’, these words encapsulate the idea of ‘the Norman Yoke’ – that the Battle of Hastings sparked the cruel oppression of Anglo-Saxon liberties by a foreign ruling class. Certainly, William the Conqueror proclaimed his power in great castles and cathedrals, turned the church upside down and even changed the colour of scribal ink. But was it really such a terrible time for the Anglo Saxons or was the idea of beastly Norman oppressors and noble Saxon sufferers invented later to shore up the idea of Englishness?

The Laws of Motion

The Laws of Motion

Melvyn Bragg and guests discuss Newton’s Laws of Motion. In 1687 Isaac Newton attempted to explain the movements of everything in the universe, from a pea rolling on a plate to the position of the planets. It was a brilliant, vaultingly ambitious and fiendishly complex task; it took him three sentences. These are the three laws of motion with which Newton founded the discipline of classical mechanics and conjoined a series of concepts - inertia, acceleration, force, momentum and mass - by which we still describe the movement of things today. Newton’s laws have been refined over the years – most famously by Einstein - but they were still good enough, 282 years after they were published, to put Neil Armstrong on the Moon. With Simon Schaffer, Professor in History and Philosophy of Science at the University of Cambridge and Fellow of Darwin College; Raymond Flood, University Lecturer in Computing Studies and Mathematics and Senior Tutor at Kellogg College, University of Oxford; Rob Iliffe, Professor of Intellectual History and History of Science at the University of Sussex.

The Dissolution of the Monasteries

The Dissolution of the Monasteries

Melvyn Bragg and guests discuss Henry VIII and the Dissolution of the Monasteries. Was Henry’s decision to destroy monastic culture in this country a tyrannical act of grand larceny or the pious destruction of a corrupt institution? When he was an old man, Michael Sherbrook remembered the momentous events of his youth: “All things of price were either spoiled, plucked away or defaced to the uttermost…it seemed that every person bent himself to filch and spoil what he could. Nothing was spared but the ox-houses and swincotes…” He was talking about the destruction of Roche Abbey, but it could have been Lewes or Fountains, Glastonbury, Tintern or Walsingham, names that haunt the religious past as their ruins haunt the landscape. These were the monasteries, suddenly and for many shockingly, destroyed during the reign of Henry VIII.The conflict was played out with a mix of violence, heroism, political manoeuvring and genuine theological disputation. But what was lost in terms of architecture, painting, treasure and in the religious habits of the monasteries themselves and of the common people who lived with them?With Diarmaid MacCulloch, Professor of the History of the Church at Oxford University; Diane Purkiss, Fellow and Tutor at Keble College, Oxford; George Bernard, Professor of Early Modern History at the University of Southampton

Kierkegaard

Kierkegaard

Melvyn Bragg and guests discuss the rich and radical ideas of Soren Kierkegaard, often called the father of Existentialism.In 1840 a young Danish girl called Regine Olsen got engaged to her sweetheart – a modish and clever young man called Søren Kierkegaard. The two were deeply in love but soon the husband to be began to have doubts. He worried that he couldn’t make Regine happy and stay true to himself and his dreams of philosophy. It was a terrible dilemma, but Kierkegaard broke off the engagement – a decision from which neither he nor his fiancée fully recovered. This unhappy episode has become emblematic of the life and thought of Søren Kierkegaard - a philosopher who confronted the painful choices in life and who understood the darker modes of human existence. Yet Kierkegaard is much more than the gloomy Dane of reputation. A thinker of wit and elegance, his ability to live with paradox and his desire to think about individuals as free have given him great purchase in the modern world and he is known as the father of Existentialism.With Jonathan Rée, Visiting Professor at Roehampton University and the Royal College of Art; Clare Carlisle, Lecturer in Philosophy at the University of Liverpool; John Lippitt, Professor of Ethics and Philosophy of Religion at the University of Hertfordshire.

The Greek Myths

The Greek Myths

Melvyn Bragg and guests discuss the Greek myths from Achilles to Zeus. Are you a touch narcissistic? Do you have the body of an Adonis? Are you willing to undertake Herculean tasks or Promethean ventures? Perhaps you have an Oedipus complex? If you answer to any or perhaps all of these you owe something to the Greek myths, a collection of weird and wonderful stories that, like Penelope’s shroud or the needlework of Arachne, were constantly woven and unpicked across centuries of Greek and Roman civilisation. The myths have a cast of thousands including mighty Zeus, Jason and the Argonauts, wily Odysseus, beautiful Aphrodite and Cerberus, the three-headed dog. They are funny, shocking, quirky and epic and have retained their power and their wisdom from the ancient world to the modern. With Nick Lowe, Senior Lecturer in Classics at Royal Holloway, University of London; Richard Buxton, Professor of Greek Language and Literature at the University of Bristol; Mary Beard, Professor of Classics at Cambridge University

Ada Lovelace

Ada Lovelace

Melvyn Bragg and guests discuss the 19th century mathematician Ada Lovelace. Deep in the heart of the Pentagon is a network of computers. They control the US military, the most powerful army on the planet, but they are controlled by a programming language called Ada. It’s named after Ada Lovelace, the allegedly hard drinking 19th century mathematician and daughter of Lord Byron. In her work with Charles Babbage on a steam driven calculating machine called the Difference Engine, Ada understood, perhaps before anyone else, what a computer might truly be. As such the Difference Engine is the spiritual ancestor of the modern computer.Ada Lovelace has been called many things - the first computer programmer and a prophet of the computer age – but most poetically perhaps by Babbage himself as an ‘enchantress of numbers’.With Patricia Fara, Senior Tutor at Clare College, Cambridge; Doron Swade, Visiting Professor in the History of Computing at Portsmouth University; John Fuegi, Visiting Professor in Biography at Kingston University.

Lear

Lear

Melvyn Bragg and guests discuss King Lear. Around the turn of 1606, a group of London theatre-goers braved the plague to take in a new play by the well-known impresario, Mr William Shakespeare. Packed into the Globe Theatre, they were treated to a tale of violence, hatred and betrayal so upsetting that it thereafter languished among Shakespeare’s less popular plays.The story of Lear – of a man who divides up his property and loses the love of a daughter - is an ancient and ultimately happy one. But in the hands of William Shakespeare it became a shocking and violent vision of a broken family in a godless universe. So shocking that after the playwright’s death it was shunned and rewritten with a happy ending. Only in the 19th and 20th centuries did Shakespeare’s bleak, experimental and disorientating drama attain the status it has now. But why did Shakespeare take a story from the deep history of Britain and make it so shockingly his own and when, from the Civil War to the Second World War, did this powerful and confusing tragedy emerge as Shakespeare’s greatest? With Jonathan Bate, Professor of English Literature at the University of Warwick; Katherine Duncan-Jones, Tutorial Fellow in English at Somerville College, Oxford; Catherine Belsey, Research Professor in English at the University of Wales, Swansea
