Roger Bacon

The 13th-century English philosopher Roger Bacon is perhaps best known for his major work the Opus Maius. Commissioned by Pope Clement IV, this extensive text covered a multitude of topics from mathematics and optics to religion and moral philosophy. He is also regarded by some as an early pioneer of the modern scientific method. Bacon's erudition was so highly regarded that he came to be known as 'Doctor Mirabilis' or 'wonderful doctor'. However, he is a man shrouded in mystery. Little is known about much of his life and he became the subject of a number of strange legends, including one in which he allegedly constructed a mechanical brazen head that would predict the future. With:Jack Cunningham Academic Coordinator for Theology at Bishop Grosseteste University, LincolnAmanda Power Associate Professor of Medieval History at the University of Oxford Elly Truitt Associate Professor of Medieval History at Bryn Mawr CollegeProducer: Victoria Brignell.

Rosa Luxemburg

Melvyn Bragg discusses the life and times of Rosa Luxemburg (1871-1919), 'Red Rosa', who was born in Poland under the Russian Empire and became one of the leading revolutionaries in an age of revolution. She was jailed for agitation and for her campaign against the Great War which, she argued, pitted workers against each other for the sake of capitalism. With Karl Liebknecht and other radicals, she founded the Spartacus League in the hope of ending the war through revolution. She founded the German Communist Party with Liebknecht; with the violence that followed the German Revolution of 1918, her opponents condemned her as Bloody Rosa. She and Liebknecht were seen as ringleaders in the Spartacus Revolt of 1919 and, on 15th January 1919, the Freikorps militia arrested and murdered them. While Luxemburg has faced opposition for her actions and ideas from many quarters, she went on to become an iconic figure in East Germany under the Cold War and a focal point for opposition to the Soviet-backed leadership.With Jacqueline Rose Co-Director of the Birkbeck Institute for the Humanities, Birkbeck, University of LondonMark Jones Irish Research Council fellow at the Centre for War Studies, University College Dublinand Nadine Rossol Senior lecturer in Modern European History at the University of EssexProducer: Simon Tillotson.

Pauli's Exclusion Principle

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter’s chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this fifth of his choices, we hear Melvyn Bragg and his guests discuss a key figure from quantum mechanics.Their topic is the life and ideas of Wolfgang Pauli (1900-1958), whose Exclusion Principle is one of the key ideas in quantum mechanics. A brilliant physicist, at 21 Pauli wrote a review of Einstein's theory of general relativity and that review is still a standard work of reference today. The Pauli Exclusion Principle proposes that no two electrons in an atom can be at the same time in the same state or configuration, and it helps explain a wide range of phenomena such as the electron shell structure of atoms. Pauli went on to postulate the existence of the neutrino, which was confirmed in his lifetime. Following further development of his exclusion principle, Pauli was awarded the Nobel Prize in Physics in 1945 for his 'decisive contribution through his discovery of a new law of Nature'. He also had a long correspondence with Jung, and a reputation for accidentally breaking experimental equipment which was dubbed The Pauli Effect.With Frank Close Fellow Emeritus at Exeter College, University of OxfordMichela Massimi Professor of Philosophy of Science at the University of EdinburghandGraham Farmelo Bye-Fellow of Churchill College, University of CambridgeProducer: Simon TillotsonSpanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious.

The Paleocene-Eocene Thermal Maximum

Exploring the Paleocene-Eocene Thermal Maximum, a period of rapid climate change marked by increased temperatures and extinctions. The rise in temperature was attributed to an increase in carbon dioxide and methane, possibly released from frozen crystals in the sea bed. The podcast discusses the evidence for this event, including changes in fossil plants and animals, and the process of drilling into deep sea sediments to uncover valuable insights. It also explores the significance of the Paleocene-Eocene Thermal Maximum for understanding current climate change and the potential threats of methane hydrates.

North and South

Melvyn Bragg and guests discuss Elizabeth Gaskell's novel North and South, published in 1855 after serialisation in Dickens' Household Words magazine. It is the story of Margaret Hale, who was raised in the South in the New Forest and London's Harley Street, and then moves North to a smokey mill town, Milton, in Darkshire. As well as Margaret's emotional life and her growing sense of independence, the novel explores the new ways of living thrown up by industrialisation, and the relationships between 'masters and men'. Many of Margaret Hale's experiences echo Gaskell's own life, as she was born in Chelsea and later moved to Manchester, and the novel has become valued for its insights into social conflicts and the changing world in which Gaskell lived.With Sally Shuttleworth Professor of English Literature at the University of OxfordDinah Birch Pro-vice Chancellor for Research and Professor of English Literature at the University of LiverpoolAndJenny Uglow Biographer of Elizabeth GaskellProducer: Simon Tillotson.

Seneca the Younger

Melvyn Bragg and guests discuss Seneca the Younger, who was one of the first great writers to live his entire life in the world of the new Roman empire, after the fall of the Republic. He was a Stoic philosopher, he wrote blood-soaked tragedies, he was an orator, and he navigated his way through the reigns of Caligula, Claudius and Nero, sometimes exercising power at the highest level and at others spending years in exile. Agrippina the Younger was the one who called for him to tutor Nero, and it is thought Seneca helped curb some of Nero's excesses. He was later revered within the Christian church, partly for what he did and partly for what he was said to have done in forged letters to St Paul. His tragedies, with their ghosts and high body count, influenced Shakespeare's Titus Andronicus and Hamlet, and Kyd's Spanish Tragedy. The image above is the so-called bust of Seneca, a detail from Four Philosophers by Peter Paul Rubens.WithMary Beard Professor of Classics at the University of CambridgeCatharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonandAlessandro Schiesaro Professor of Classics at the University of ManchesterProducer: Simon Tillotson.

Maths in the Early Islamic World

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.
