In Our Time With Melvyn Bragg Folgen

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.
