The Rapture

Melvyn Bragg and guests discuss the flourishing of maths in the early Islamic world, as thinkers from across the region developed ideas in places such as Baghdad's House of Wisdom. Among them were the Persians Omar Khayyam, who worked on equations, and Al-Khwarizmi, latinised as Algoritmi and pictured above, who is credited as one of the fathers of algebra, and the Jewish scholar Al-Samawal, who converted to Islam and worked on mathematical induction. As well as the new ideas, there were many advances drawing on Indian, Babylonian and Greek work and, thanks to the recording or reworking by mathematicians in the Islamic world, that broad range of earlier maths was passed on to western Europe for further study.With Colva Roney-Dougal Reader in Pure Mathematics at the University of St AndrewsPeter Pormann Professor of Classics & Graeco-Arabic Studies at the University of ManchesterAndJim Al-Khalili Professor of Physics at the University of SurreyProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the Northamptonshire poet John Clare who, according to one of Melvyn's guests Jonathan Bate, was 'the greatest labouring-class poet that England has ever produced'. Clare worked in a tavern, as a gardener and as a farm labourer in the early 19th century and achieved his first literary success with Poems Descriptive of Rural Life and Scenery. He was praised for his descriptions of rural England and his childhood there, and his reaction to the changes he saw in the Agricultural Revolution with its enclosures, displacement and altered, disrupted landscape. Despite poor mental health and, from middle age onwards, many years in asylums, John Clare continued to write and he is now seen as one of the great poets of his age.With Sir Jonathan Bate Provost of Worcester College, University of OxfordMina Gorji Senior Lecturer in the English Faculty and fellow of Pembroke College, Cambridgeand Simon Kövesi Professor of English Literature at Oxford Brookes UniversityProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the political philosophy of Hannah Arendt. She developed many of her ideas in response to the rise of totalitarianism in the C20th, partly informed by her own experience as a Jew in Nazi Germany before her escape to France and then America. She wanted to understand how politics had taken such a disastrous turn and, drawing on ideas of Greek philosophers as well as her peers, what might be done to create a better political life. Often unsettling, she wrote of 'the banality of evil' when covering the trial of Eichmann, one of the organisers of the Holocaust.WithLyndsey Stonebridge Professor of Modern Literature and History at the University of East AngliaFrisbee Sheffield Lecturer in Philosophy at Girton College, University of CambridgeandRobert Eaglestone Professor of Contemporary Literature and Thought at Royal Holloway, University LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the relationship between parasites and hosts, where one species lives on or in another to the benefit of the parasite but at a cost to the host, potentially leading to disease or death of the host. Typical examples are mistletoe and trees, hookworms and vertebrates, cuckoos and other birds. In many cases the parasite species do so well in or on a particular host that they reproduce much faster and can adapt to changes more efficiently, and it is thought that almost half of all animal species have a parasitic stage in their lifetime. What techniques do hosts have to counter the parasites, and what impact do parasites have on the evolution of their hosts?

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the history of Mary, Queen of Scots, who had potential to be one of the most powerful rulers in Europe, yet she was also one of the most vulnerable. In France, when she was the teenage bride to their future king, she was seen as rightful heir to the thrones of England and Ireland, as well as Queen of Scotland and one day of France, which would have been an extraordinary union. She was widowed too young, though and, a Catholic returning to Protestant Scotland, she struggled to overcome rivalries in her own country. She fled to Protestant England, where she was implicated in plots to overthrow Elizabeth, and it was Elizabeth herself who signed Mary's death warrant.

Melvyn Bragg and guests discuss Nietzsche's On The Genealogy of Morality - A Polemic, which he published in 1887 towards the end of his working life and in which he considered the price humans have paid, and were still paying, to become civilised. In three essays, he argued that having a guilty conscience was the price of living in society with other humans. He suggested that Christian morality, with its consideration for others, grew as an act of revenge by the weak against their masters, 'the blond beasts of prey', as he calls them, and the price for that slaves' revolt was endless self-loathing. These and other ideas were picked up by later thinkers, perhaps most significantly by Sigmund Freud who further explored the tensions between civilisation and the individual.WithStephen Mulhall Professor of Philosophy and a Fellow and Tutor at New College, University of OxfordFiona Hughes Senior Lecturer in Philosophy at the University of EssexAndKeith Ansell-Pearson Professor of Philosophy at the University of WarwickProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the German astronomer Johannes Kepler (1571 - 1630). Although he is overshadowed today by Isaac Newton and Galileo, he is considered by many to be one of the greatest scientists in history. The three laws of planetary motion Kepler developed transformed people's understanding of the Solar System and laid the foundations for the revolutionary ideas Isaac Newton produced later. Kepler is also thought to have written one of the first works of science fiction. However, he faced a number of challenges. He had to defend his mother from charges of witchcraft, he had few financial resources and his career suffered as a result of his Lutheran faith.
