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 Siege of Munster

The Siege of Munster

Melvyn Bragg and guests Diarmaid MacCulloch, Lucy Wooding and Charlotte Methuen discuss the Siege of Munster in 1534-35.In the early 16th century, the Protestant Reformation revolutionised Christian belief. But one radical group of believers stood out. The Anabaptists rejected infant baptism and formal clergy, and believed that all goods should be held in common. They were also convinced that the Second Coming was imminent.In 1534, in the north-western German city of Munster, a group of Anabaptists attempted to establish the 'New Jerusalem', ready for the Last Days before the coming Apocalypse. But the city was besieged by its ousted Prince-Bishop, and under the reign of its self-appointed King, a 25-year-old Dutchman called Jan van Leyden, it descended into tyranny. Books were burned, dissenters were executed and women were forced to marry. As starvation spread, King Jan lived in luxury with his 16 wives. The horrors of Munster have resonated through the European memory ever since. Diarmaid MacCulloch is Professor of the History of the Church at the University of Oxford; Charlotte Methuen is University Research Lecturer in Ecclesiastical History at the University of Oxford and Lecturer in Church History and Liturgy at Ripon College Cuddesdon; Lucy Wooding is Lecturer in Early Modern History at King's College, London.

Schopenhauer

Schopenhauer

Melvyn Bragg and guests AC Grayling, Beatrice Han-Pile and Christopher Janaway discuss the dark, pessimistic philosophy of Arthur Schopenhauer.As a radical young thinker in Germany in the early 19th century, Schopenhauer railed against the dominant ideas of the day. He dismissed the pre-eminent German philosopher Georg Hegel as a pompous charlatan, and turned instead to the Enlightenment thinking of Immanuel Kant for inspiration. Schopenhauer's central idea was that everything in the world was driven by the Will - broadly, the ceaseless desire to live. But this, he argued, left us swinging pointlessly between suffering and boredom. The only escape from the tyranny of the Will was to be found in art, and particularly in music. Schopenhauer was influenced by Eastern philosophy, and in turn his own work had an impact well beyond the philosophical tradition in the West, helping to shape the work of artists and writers from Richard Wagner to Marcel Proust, and Albert Camus to Sigmund Freud.AC Grayling is Professor of Philosophy at Birkbeck College, University of London; Beatrice Han-Pile is Professor of Philosophy at the University of Essex; Christopher Janaway is Professor of Philosophy at the University of Southampton.

The Geological Formation of Britain

The Geological Formation of Britain

Melvyn Bragg and guests Richard Corfield, Jane Francis and Sanjeev Gupta discuss the geological formation of Britain.Around 600 million years ago the island that we now call Britain was in two parts, far to the south of the Equator. Scotland and north-western Ireland were part of a continent (Laurentia) that also included what is now North America. To the south-east, near the Antarctic Circle, meanwhile, you would have found southern Ireland, England and Wales. They formed a mini-continent (Avalonia) with what is now Newfoundland.Over the course of hundreds of millions of years, as they inched their way north, the two parts came together - first as part of a vast unitary continent (Pangaea), later as a promontory on the edge of Europe, and eventually, as sea levels rose, as an island. The story of how Britain came to be where it is now, in its current shape - from the separation of North America and Europe to the carving out of the English Channel - is still being uncovered today.Richard Corfield is Visiting Senior Resarch Fellow at Oxford University; Jane Francis is Professor of Palaeoclimatology at the University of Leeds; Sanjeev Gupta is a Royal Society-Leverhulme Trust Research Fellow at Imperial College London.

The Death of Elizabeth I

The Death of Elizabeth I

Melvyn Bragg and guests John Guy, Clare Jackson and Helen Hackett discuss the death of Queen Elizabeth I and its immediate impact, as a foreign monarch became King in the face of plots and plague.By the spring of 1603, Elizabeth had been Queen for 44 years, and it was clear that she would leave no heir. Many feared that her death would spark insurrection, led perhaps by Puritans, perhaps by Catholics, possibly with the support of Spain. As it became clear that she was dying, Elizabeth's chief minister, Sir Robert Cecil, put into action his covert strategy to secure the succession of King James the Sixth of Scotland.What follows is a story of plots, plague and high politics, as a foreign monarch brought a thoroughly Continental approach to Kingship to the English throne. James's accession was widely welcomed, but his relationship with Cecil was initially tense, and his long procession south from Edinburgh attracted both celebration and criticism. His treatise on Kingship, published on his succession, became a bestseller in London - at least until an outbreak of plague, which also drove him from the capital not long after he arrived. His coronation was hurried through to circumvent plots against him, but his triumphal entry into London had to be delayed until a year after Elizabeth's death. And, as the high expectations which first greeted James were increasingly frustrated, the English started to invoke the ghost of their dead Queen to criticise their new ruler.John Guy is a Fellow of Clare College, University of Cambridge; Clare Jackson is Lecturer and Director of Studies in History at Trinity Hall, University of Cambridge; Helen Hackett is Reader in English at University College, London.

The Dreyfus Affair

The Dreyfus Affair

Melvyn Bragg and guests Robert Gildea, Ruth Harris and Robert Tombs discuss the Dreyfus Affair, the 1890s scandal which divided opinion in France for a generation.In 1894, a high-flying Jewish staff officer in the French Army, one Alfred Dreyfus, was convicted of spying for the Prussians. He was publicly humiliated: before a large Paris crowd, he was stripped of his badges of rank and his sword was ceremonially broken. Some of those watching shouted 'Down with Judas!' Then he was dispatched to Devil's Island. But when it emerged that Dreyfus was innocent, a scandal erupted which engulfed the Army, the Church and French society as a whole, exposing deep political rifts, and the nation's endemic anti-Semitism. It pitted Catholics against Republicans, provoked fighting in the streets, and led to the prosecution of the novelist Emile Zola, after his famous J'Accuse polemic against those protecting the real spy and so prolonging Dreyfus's suffering. The Affair became so divisive that it posed a serious threat to the French Republic itself. Finally, in 1905, it prompted the separation of Church and State. The scandal and the anti-Semitism at the heart of it cast a very long shadow. In 1945, when the ultra-nationalist one-time 'anti-Dreyfusard' Charles Maurras was convicted of collaborating with the Nazis, he reacted by declaring that his punishment was Dreyfus's revenge.

Akhenaten

Akhenaten

Melvyn Bragg and guests Elizabeth Frood, Richard Parkinson and Kate Spence discuss the Pharaoh Akhenaten, the ruler who brought revolutionary change to ancient Egypt. During his reign, Akhenaten embarked on a profoundly radical project: he set out to transform his people's deepest religious beliefs, moving from a polytheistic tradition to the elevation of a single solar god, Aten. The changes in art and architecture that followed have led some to call him 'history's first individual'. Despite his successors' attempts to obliterate him from the historical record, Akhenaten - and his wife Nefertiti - have been an endless source of fascination and speculation.Richard Parkinson is an Egyptologist at the British Museum; Elizabeth Frood is a Lecturer in Egyptology at the University of Oxford; Kate Spence is a Lecturer in the Archaeology of Ancient Egypt at the University of Cambridge.

Calculus

Calculus

Melvyn Bragg discusses the epic feud between Sir Isaac Newton and Gottfried Leibniz over who invented an astonishingly powerful new mathematical tool - calculus. Both claimed to have conceived it independently, but the argument soon descended into a bitter battle over priority, plagiarism and philosophy. Set against the backdrop of the Hanoverian succession to the English throne and the formation of the Royal Society, the fight pitted England against Europe, geometric notation against algebra. It was fundamental to the grounding of a mathematical system which is one of the keys to the modern world, allowing us to do everything from predicting the pressure building behind a dam to tracking the position of a space shuttle.Melvyn is joined by Simon Schaffer, Professor of History of Science at the University of Cambridge and Fellow of Darwin College; Patricia Fara, Senior Tutor at Clare College, University of Cambridge; and Jackie Stedall, Departmental Lecturer in History of Mathematics at the University of Oxford.

St Thomas Aquinas

St Thomas Aquinas

Melvyn Bragg discusses the life, works and enduring influence of the medieval philosopher and theologian St Thomas Aquinas with Martin Palmer, John Haldane and Annabel Brett. St Thomas Aquinas' ideas remain at the heart of the official doctrine of the Roman Catholic Church today and inform philosophical debates on human rights, natural law and what constitutes a 'just war'.Martin Palmer is Director of the International Consultancy on Religion, Education and Culture; John Haldane is Professor of Philosophy at the University of St Andrews; Annabel Brett is Lecturer in History at Gonville and Caius College, Cambridge.
