Melvyn Bragg and guests Serafina Cuomo, John O'Connor and Ian Stewart discuss the ideas and influence of the Greek mathematician Pythagoras and his followers, the Pythagoreans.The Ancient Greek mathematician Pythagoras is probably best known for the theorem concerning right-angled triangles that bears his name. However, it is not certain that he actually developed this idea; indeed, some scholars have questioned not only his true intellectual achievements, but whether he ever existed. We do know that a group of people who said they were followers of his - the Pythagoreans - emerged around the fifth century BC. Melvyn Bragg and his guests discuss what we do and don't know about this legendary figure and his followers, and explore the ideas associated with them. Some Pythagoreans, such as Philolaus and Archytas, were major mathematical figures in their own right. The central Pythagorean idea was that number had the capacity to explain the truths of the world. This was as much a mystical belief as a mathematical one, encompassing numerological notions about the 'character' of specific numbers. Moreover, the Pythagoreans lived in accordance with a bizarre code which dictated everything from what they could eat to how they should wash. Nonetheless, Pythagorean ideas, centred on their theory of number, have had a profound impact on Western science and philosophy, from Plato through astronomers like Copernicus to the present day.Serafina Cuomo is Reader in Roman History at Birkbeck College, University of London; John O'Connor is Senior Lecturer in Mathematics at the University of Saint Andrews; Ian Stewart is Emeritus Professor of Mathematics at the University of Warwick.

Melvyn Bragg and guests Tim Barrett, Naomi Standen and Frances Wood discuss the Silk Road, the trade routes which spanned Asia for over a thousand years, carrying Buddhism to China and paper-making and gunpowder westwards.In 1900, a Taoist monk came upon a cave near the Chinese town of Dunhuang. Inside, he found thousands of ancient manuscripts. They revealed a vast amount of evidence about the so-called Silk Road: the great trade routes which had stretched from Central Asia, through desert oases, to China, throughout the first millennium.Besides silk, the Silk Road helped the dispersion of writing and paper-making, coinage and gunpowder, and it was along these trade routes that Buddhism reached China from India. The history of these transcontinental links reveals a dazzlingly complex meeting and mingling of civilisations, which lasted for well over a thousand years.With:Tim Barrett is Professor of East Asian History at the School of Oriental and African Studies; Naomi Standen is Senior Lecturer in Chinese Studies at Newcastle University; Frances Wood is Head of the Chinese Section at the British Library.

Melvyn Bragg and guests Roy Foster, Jeri Johnson and Katherine Mullin discuss A Portrait of the Artist as a Young Man, James Joyce's groundbreaking 1916 novel about growing up in Catholic Ireland.Many novelists choose their own young life as the subject for their first book. But very few have subjected themselves to the intense self-scrutiny of the great Irish novelist James Joyce. In A Portrait of the Artist as a Young Man, published in 1916, Joyce follows his alter ego, Stephen Dedalus, from babyhood to young adulthood. He takes us from Stephen wetting the bed, through a teenage visit to a prostitute, and on through religious terrors to the prospect of freedom. When it was published, the book met with shock at its graphic honesty. Joyce shows Stephen wrestling with the pressures of his family, his Church and his nation. Yet this was far from being a straightforward youthful tirade. Joyce's novel is also daringly experimental, taking us deep into Stephen's psyche. And since its publication almost a century ago, it has had a huge influence on novelists across the world.With: Roy Foster, Carroll Professor of Irish History and Fellow of Hertford College, OxfordJeri Johnson, Senior Fellow in English at Exeter College, OxfordKatherine Mullin, Senior Lecturer in English Literature at the University of Leeds.

Melvyn Bragg and guests Paul Cartledge, Edith Hall and Angie Hobbs discuss Sparta, the militaristic Ancient Greek city-state, and the political ideas it spawned.The isolated Ancient Greek city-state of Sparta was a ferocious opposite to the cosmopolitan port of Athens. Spartans were hostile to outsiders and rhetoric, to philosophy and change. Two and a half thousand years on, Sparta remains famous for its brutally rigorous culture of military discipline, as inculcated in its young men through communal living, and terrifying, licensed violence towards the Helots, the city-state's subjugated majority. Sparta and its cruelty was used as an argument against slavery by British Abolitionists in the early 1800s, before inspiring the Nazis in the 1930s and 1940s.Yet Sparta also produced poets of great skill: Tyrteaus wrote marching songs for the young men; Alcman wrote choral lyrics for the young women. Moreover, the city-state's rulers pioneered a radically egalitarian political system, and its ideals were invoked by Plato. Its inhabitants also prided themselves on their wit: we don't only derive the word 'spartan' from their culture, but the word 'laconic'.

Melvyn Bragg and guests Jim Al-Khalili, Frank Close and Frank James discuss the history of the discovery of radiation.Today the word 'radiation' conjures up images of destruction. But in physics, it simply describes the emission, transmission and absorption of energy, and the discovery of how radiation works has allowed us to identify new chemical elements, treat cancer and work out what the stars are made of.Over the course of the 19th century, physicists from Thomas Young, through Michael Faraday to Henri Becquerel made discovery after discovery, gradually piecing together a radically new picture of reality. They explored the light beyond the visible spectrum, connected electricity and magnetism, and eventually showed that heat, light, radio and mysterious new phenomena like 'X-rays' were all forms of 'electromagnetic wave'. In the early 20th century, with the discovery of radioactivity, scientists like Max Planck and Ernest Rutherford completed the picture of the 'electromagnetic spectrum'. This was a cumulative achievement that transformed our vision of the physical world, and what we could do in it.Jim Al-Khalili is Professor of Theoretical Physics and Chair in the Public Engagement in Science at the University of Surrey; Frank Close is Professor of Physics at Exeter College, University of Oxford; Frank James is Professor of the History of Science at the Royal Institution.

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.

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.

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.
