Melvyn Bragg and his guests discuss the Sun. The object that gives the Earth its light and heat is a massive ball of gas and plasma 93 million miles away. Thanks to the nuclear fusion reactions taking place at its core, the Sun has been shining for four and a half billion years. Its structure, and the processes that keep it burning, have fascinated astronomers for centuries. After the invention of the telescope it became apparent that the Sun is not a placid, steadily shining body but is subject to periodic changes in its appearance and eruptions of dramatic violence, some of which can affect us here on Earth. Recent space missions have revealed fascinating new insights into our nearest star.With:Carolin Crawford Gresham Professor of Astronomy and Fellow of Emmanuel College, CambridgeYvonne Elsworth Poynting Professor of Physics at the University of BirminghamLouise Harra Professor of Solar Physics at UCL Mullard Space Science LaboratoryProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Virginia Woolf's novel Mrs Dalloway. First published in 1925, it charts a single day in the life of Clarissa Dalloway, a prosperous member of London society, as she prepares to throw a party. Writing in her diary during the writing of the book, Woolf explained what she had set out to do: 'I want to give life and death, sanity and insanity. I want to criticize the social system, and to show it at work at its most intense.' Celebrated for its innovative narrative technique and distillation of many of the preoccupations of 1920s Britain, Mrs Dalloway is now seen as a landmark of twentieth-century fiction, and one of the finest products of literary modernism.With:Professor Dame Hermione Lee President of Wolfson College, OxfordJane Goldman Reader in English Literature at the University of GlasgowKathryn Simpson Senior Lecturer in English Literature at Cardiff Metropolitan University.

Melvyn Bragg and his guests discuss one of the most remarkable figures of the Middle Ages, Hildegard of Bingen. The abbess of a Benedictine convent, Hildegard experienced a series of mystical visions which she documented in her writings. She was an influential person in the religious world and much of her extensive correspondence with popes, monarchs and other important figures survives. Hildegard was also celebrated for her wide-ranging scholarship, which as well as theology covered the natural world, science and medicine. Officially recognised as a saint by the Catholic Church in 2012, Hildegard is also one of the earliest known composers. Since their rediscovery in recent decades her compositions have been widely recorded and performed.With:Miri Rubin Professor of Medieval and Early Modern History and Head of the School of History at Queen Mary, University of LondonWilliam Flynn Lecturer in Medieval Latin at the Institute for Medieval Studies at the University of LeedsAlmut Suerbaum Professor of Medieval German and Fellow of Somerville College, Oxford.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the philosophy of solitude. The state of being alone can arise for many different reasons: imprisonment, exile or personal choice. It can be prompted by religious belief, personal necessity or a philosophical need for solitary contemplation. Many thinkers have dealt with the subject, from Plato and Aristotle to Hannah Arendt. It's a philosophical tradition that takes in medieval religious mystics, the work of Montaigne and Adam Smith, and the great American poets of solitude Thoreau and Emerson.With:Melissa Lane Professor of Politics at Princeton UniversitySimon Blackburn Professor of Philosophy at the New College of the Humanities and Fellow of Trinity College, CambridgeJohn Haldane Professor of Philosophy at the University of St AndrewsProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the life and work of Robert Boyle, a pioneering scientist and a founder member of the Royal Society. Born in Ireland in 1627, Boyle was one of the first natural philosophers to conduct rigorous experiments, laid the foundations of modern chemistry and derived Boyle's Law, describing the physical properties of gases. In addition to his experimental work he left a substantial body of writings about philosophy and religion; his piety was one of the most important factors in his intellectual activities, prompting a celebrated dispute with his contemporary Thomas Hobbes.With:Simon Schaffer Professor of the History of Science at the University of CambridgeMichael Hunter Emeritus Professor of History at Birkbeck College, University of LondonAnna Marie Roos Senior Lecturer in the History of Science and Medicine at the University of LincolnProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Bluestockings. Around the middle of the eighteenth century a small group of intellectual women began to meet regularly to discuss literature and other matters, inviting some of the leading thinkers of the day to take part in informal salons. In an age when women were not expected to be highly educated, the Bluestockings were sometimes regarded with suspicion or even hostility. But prominent members such as Elizabeth Montagu - known as 'the Queen of the Bluestockings', and author of an influential essay about Shakespeare - and the classicist Elizabeth Carter were highly regarded for their scholarship. Their accomplishments led to far greater acceptance of women as the intellectual equal of men, and furthered the cause of female education.With:Karen O'Brien Vice-Principal and Professor of English at King's College LondonElizabeth Eger Reader in English Literature at King's College LondonNicole Pohl Reader in English Literature at Oxford Brookes UniversityProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the history and contents of the Talmud, one of the most important texts of Judaism. The Talmud was probably written down over a period of several hundred years, beginning in the 2nd century. It contains the authoritative text of the traditional Jewish oral law, and also an account of early Rabbinic discussion of, and commentary on, these laws. In later centuries scholars wrote important commentaries on these texts, which remain central to most strands of modern Judaism.With:Philip Alexander Emeritus Professor of Jewish Studies at the University of ManchesterRabbi Norman Solomon Former Lecturer at the Oxford Centre for Jewish and Hebrew StudiesLaliv Clenman Lecturer in Rabbinic Literature at Leo Baeck College and a Visiting Lecturer at the Department of Theology and Religious Studies, King's College LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Rubaiyat of Omar Khayyam. In 1859 the poet Edward FitzGerald published a long poem based on the verses of the 11th-century Persian scholar Omar Khayyam. Not a single copy was sold in the first few months after the work's publication, but after it came to the notice of members of the Pre-Raphaelite Brotherhood it became enormously influential. Although only loosely based on the original, the Rubaiyat made Khayyam the best-known Eastern poet in the English-speaking world. FitzGerald's version is itself one of the most admired works of Victorian literature, praised and imitated by many later writers.With:Charles Melville Professor of Persian History at the University of CambridgeDaniel Karlin Winterstoke Professor of English Literature at the University of BristolKirstie Blair Professor of English Studies at the University of StirlingProducer: Thomas Morris.
