Melvyn Bragg and guests discuss Isambard Kingdom Brunel, the Victorian engineer responsible for bridges, tunnels and railways still in use today more than 150 years after they were built. Brunel represented the cutting edge of technological innovation in Victorian Britain, and his life gives us a window onto the social changes that accompanied the Industrial Revolution. Yet his work was not always successful, and his innovative approach to engineering projects was often greeted with suspicion from investors. Guests:Julia Elton, former President of the Newcomen Society for the History of Engineering and TechnologyBen Marsden, Senior Lecturer in the School of Divinity, History and Philosophy at the University of AberdeenCrosbie Smith, Professor of the History of Science at the University of KentProducer: Luke Mulhall.

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.
