In Our Time

Melvyn Bragg and guests discuss the Egyptian pharaoh Hatshepsut, whose name means 'foremost of noble ladies'. She ruled Egypt from about 1479 - 1458 BC and some scholars argue that she was one of the most successful and influential pharaohs. When she came to the throne, Egypt was still recovering from a period of turbulence known as the Second Intermediate Period a few generations earlier. Hatshepsut reasserted Egyptian power by building up international trade and commissioned buildings considered masterpieces of Egyptian architecture. She also made significant changes to the ideology surrounding the pharaoh and the gods. However, following her death, her name was erased from the records and left out of ancient lists of Egyptian kings.With:Elizabeth Frood Associate Professor of Egyptology at the University of OxfordKate Spence Lecturer in Egyptian Archaeology at the University of CambridgeCampbell Price Curator of Egypt and Sudan at The Manchester MuseumProducer: Victoria Brignell.

Melvyn Bragg and his guests discuss nuclear fusion, the process that powers stars. In the 1920s physicists predicted that it might be possible to generate huge amounts of energy by fusing atomic nuclei together, a reaction requiring enormous temperatures and pressures. Today we know that this complex reaction is what keeps the Sun shining. Scientists have achieved fusion in the laboratory and in nuclear weapons; today it is seen as a likely future source of limitless and clean energy.Guests:Philippa Browning, Professor of Astrophysics at the University of ManchesterSteve Cowley, Chief Executive of the United Kingdom Atomic Energy AuthorityJustin Wark, Professor of Physics and fellow of Trinity College at the University of OxfordProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Haitian Revolution. In 1791 an uprising began in the French colonial territory of St Domingue. Partly a consequence of the French Revolution and partly a backlash against the brutality of slave owners, it turned into a complex struggle involving not just the residents of the island but French, English and Spanish forces. By 1804 the former slaves had won, establishing the first independent state in Latin America and the first nation to be created as a result of a successful slave rebellion. But the revolution also created one of the world's most impoverished societies, a legacy which Haiti has struggled to escape.ContributorsKate Hodgson, Postdoctoral Research Fellow in French at the University of LiverpoolTim Lockley, Reader in American Studies at the University of WarwickKaren Salt, Fellow in History in the School of Language and Literature at the University of AberdeenProducer: Luke Mulhall.

Melvyn Bragg and his guests discuss the life and work of Rudyard Kipling. Born in Bombay in 1865, Kipling has been described as the poet of Empire, celebrated for fictional works including Kim and The Jungle Book. Today his poem 'If--' remains one of the best known in the English language. Kipling was amongst the first writers in English to develop the short story as a literary form in its own right, and was the first British recipient of a Nobel Prize for Literature. A literary celebrity of the Edwardian era, Kipling's work for the Commonwealth War Graves Commission played a major role in Britain's cultural response to the First World War.Contributors:Howard Booth, Senior Lecturer in English Literature at the University of ManchesterDaniel Karlin, Winterstoke Professor of English Literature at the University of BristolJan Montefiore, Professor of Twentieth Century English Literature at the University of KentProducer: Luke Mulhall.

Melvyn Bragg and his guests discuss the Battle of Talas, a significant encounter between Arab and Chinese forces which took place in central Asia in 751 AD. It brought together two mighty empires, the Abbasid Caliphate and the Tang Dynasty, and although not well known today the battle had profound consequences for the future of both civilisations. The Arabs won the confrontation, but the battle marks the point where the Islamic Empire halted its march eastwards, and the Chinese stopped their expansion to the west. It was also a point of cultural exchange: some historians believe that it was also the moment when the technology of paper manufacture found its way from China to the Western world.GUESTSHilde de Weerdt, Professor of Chinese History at Leiden UniversityMichael Höckelmann, British Academy Postdoctoral Fellow in the Department of History at King's College LondonHugh Kennedy, Professor of Arabic at SOAS, University of LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the life, work and reputation of Julius Caesar. Famously assassinated as he entered the Roman senate on the Ides of March, 44 BC, Caesar was an inspirational general who conquered much of Europe. He was a ruthless and canny politician who became dictator of Rome, and wrote The Gallic Wars, one of the most admired and studied works of Latin literature. Shakespeare is one of many later writers to have been fascinated by the figure of Julius Caesar.With:Christopher Pelling Regius Professor of Greek at the University of OxfordCatherine Steel Professor of Classics at the University of GlasgowMaria Wyke Professor of Latin at University College LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Euler's number, also known as e. First discovered in the seventeenth century by the Swiss mathematician Jacob Bernoulli when he was studying compound interest, e is now recognised as one of the most important and interesting numbers in mathematics. Roughly equal to 2.718, e is useful in studying many everyday situations, from personal savings to epidemics. It also features in Euler's Identity, sometimes described as the most beautiful equation ever written. With:Colva Roney-Dougal Reader in Pure Mathematics at the University of St AndrewsJune Barrow-Green Senior Lecturer in the History of Maths at the Open UniversityVicky Neale Whitehead Lecturer at the Mathematical Institute and Balliol College at the University of OxfordProducer: Thomas Morris.

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 G

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

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.

Melvyn Bragg and his guests discuss photosynthesis, the process by which green plants and many other organisms use sunlight to synthesise organic molecules. Photosynthesis arose very early in evolutionary history and has been a crucial driver of life on Earth. In addition to providing most of the food consumed by organisms on the planet, it is also responsible for maintaining atmospheric oxygen levels, and is thus almost certainly the most important chemical process ever discovered.With:Nick Lane Reader in Evolutionary Biochemistry at University College LondonSandra Knapp Botanist at the Natural History MuseumJohn Allen Professor of Biochemistry at Queen Mary, University of London.Producer: Thomas Morris

Melvyn Bragg and his guests discuss the Sino-Japanese War of 1937-45. After several years of rising tension, and the Japanese occupation of Manchuria, full-scale war between Japan and China broke out in the summer of 1937. The Japanese captured many major Chinese ports and cities, but met with fierce resistance, despite internal political divisions on the Chinese side. When the Americans entered the war following the bombing of Pearl Harbor, the Japanese found themselves fighting on several fronts simultaneously, and finally capitulated in August 1945. This notoriously brutal conflict left millions dead and had far-reaching consequences for international relations in Asia.With:Rana Mitter Professor of the History and Politics of Modern China at the University of OxfordBarak Kushner Senior Lecturer in Japanese History at the University of CambridgeTehyun Ma Lecturer in Chinese History at the University of ExeterProducer: Thomas Morris.

Melvyn Bragg and his guests discuss The Tale of Sinuhe, one of the most celebrated works of ancient Egyptian literature. Written around four thousand years ago, the poem narrates the story of an Egyptian official who is exiled to Syria before returning to his homeland some years later. The number of versions of the poem, which is known from several surviving papyri and inscriptions, suggests that it was seen as an important literary work; although the story is set against a backdrop of real historical events, most scholars believe that the poem is a work of fiction.With:Richard Parkinson Professor of Egyptology and Fellow of Queen's College at the University of OxfordRoland Enmarch Senior Lecturer in Egyptology at the University of Liverpool.Aidan Dodson Senior Research Fellow in the Department of Archaeology and Anthropology at the University of BristolProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Laurence Sterne's novel Tristram Shandy. Sterne's comic masterpiece is an extravagantly inventive work which was hugely popular when first published in 1759. Its often bawdy humour, and numerous digressions, are combined with bold literary experiment, such as a page printed entirely black to mark the death of one of the novel's characters. Dr Johnson wrote that "Nothing odd will do long. Tristram Shandy did not last" - but two hundred and fifty years after the book's publication, Tristram Shandy remains one of the most influential and widely admired books of the eighteenth century.With:Judith Hawley Professor of Eighteenth-Century Literature at Royal Holloway, University of LondonJohn Mullan Professor of English at University College LondonMary Newbould Bowman Supervisor in English at Wolfson College, University of Cambridge.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Domesday Book, a vast survey of the land and property of much of England and Wales completed in 1086. Twenty years after the Battle of Hastings, William the Conqueror sent officials to most of his new territories to compile a list of land holdings and to gather information about settlements, the people who lived there and even their farm animals. Almost without parallel in European history, the resulting document was of immense importance for many centuries, and remains a central source for medieval historians.With:Stephen Baxter Reader in Medieval History at Kings College LondonElisabeth van Houts Honorary Professor of Medieval European History at the University of CambridgeDavid Bates Professorial Fellow in Medieval History at the University of East AngliaProducer: Thomas Morris.
