Sir Gawain and the Green Knight

Melvyn Bragg and guests discuss the discovery and growing understanding of the Proton, formed from three quarks close to the Big Bang and found in the nuclei of all elements. The positive charges they emit means they attract the fundamental particles of negatively charged electrons, an attraction that leads to the creation of atoms which in turn leads to chemistry, biology and life itself. The Sun (in common with other stars) is a fusion engine that turn protons by a series of processes into helium, emitting energy in the process, with about half of the Sun's protons captured so far. Hydrogen atoms, stripped of electrons, are single protons which can be accelerated to smash other nuclei and have applications in proton therapy. Many questions remain, such as why are electrical charges for protons and electrons so perfectly balanced?WithFrank Close Professor Emeritus of Physics at the University of OxfordHelen Heath Reader in Physics at the University of BristolAndSimon Jolly Lecturer in High Energy Physics at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss what Virginia Woolf called 'one of the few English novels written for grown-up people'. It was written by George Eliot, the pen name of Mary Anne Evans (1819-80), published in 8 parts in 1871-72, and was originally two separate stories which became woven together. One, 'Middlemarch', focused on a doctor, Tertius Lydgate and the other, 'Miss Brooke', on Dorothea Brooke who became the central figure in the finished work. The events are set in a small town in the Midlands, surrounded by farmland, leading up to the Reform Act 1832, and the novel explores the potential to change in matters of religion, social status, marriage and politics, and is particularly concerned with the opportunities available to women to lead fulfilling lives.

In a programme first broadcast on April 12th 2018, Melvyn Bragg and guests discuss the contribution of George Stephenson (1781-1848) and his son Robert (1803-59) to the development of the railways in C19th. George became known as The Father of Railways and yet arguably Robert's contribution was even greater, with his engineering work going far beyond their collaboration. Robert is credited with the main role in the design of their locomotives. George had worked on stationary colliery steam engines and, with Robert, developed the moving steam engine Locomotion No1 for the Stockton and Darlington Railway in 1825. They produced the Rocket for the Rainhill Trials on the Liverpool and Manchester Railway in 1829. From there, the success of their designs and engineering led to the expansion of railways across Britain and around the world. with Dr Michael Bailey Railway historian and editor of the most recent biography of Robert StephensonJulia Elton Past President of the Newcomen Society for the History of Engineering and TechnologyandColin Divall Professor Emeritus of Railway Studies at the University of YorkProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the role of slavery in the Roman world, from its early conquests to the fall of the Western Empire. The system became so entrenched that no-one appeared to question it, following Aristotle's view that slavery was a natural state. Whole populations could be marched into slavery after military conquests, and the freedom that Roman citizens prized for themselves, even in poverty, was partly defined by how it contrasted with enslavement. Slaves could be killed or tortured with impunity, yet they could be given great responsibility and, once freed, use their contacts to earn fortunes. The relationship between slave and master informed early Christian ideas of how the faithful related to God, informing debate for centuries.WithNeville Morley Professor of Classics and Ancient History at the University of ExeterUlrike Roth Senior Lecturer in Ancient History at the University of EdinburghAndMyles Lavan Senior lecturer in Ancient History at the University of St AndrewsProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Alexis de Tocqueville (1805-1859) and his examination of the American democratic system. He wrote De La Démocratie en Amérique in two parts, published in 1835 and 1840, when France was ruled by the July Monarchy of Louis-Philippe. Tocqueville was interested in how aspects of American democracy, in the age of President Andrew Jackson, could be applied to Europe as it moved away from rule by monarchs and aristocrats. His work has been revisited by politicians ever since, particularly in America, with its analysis of the strengths and weaknesses of direct democracy and its warnings of mediocrity and the tyranny of the majority.WithRobert Gildea Professor of Modern History at the University of OxfordSusan-Mary Grant Professor of American History at Newcastle Universityand Jeremy Jennings Professor of Political Theory and Head of the School of Politics & Economics at King's College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss St Augustine of Hippo's account of his conversion to Christianity and his life up to that point. Written c397AD, it has many elements of autobiography with his scrutiny of his earlier life, his long relationship with a concubine, his theft of pears as a child, his work as an orator and his embrace of other philosophies and Manichaeism. Significantly for the development of Christianity, he explores the idea of original sin in the context of his own experience. The work is often seen as an argument for his Roman Catholicism, a less powerful force where he was living in North Africa where another form of Christianity was dominant, Donatism. While Augustine retells many episodes from his own life, the greater strength of his Confessions has come to be seen as his examination of his own emotional development, and the growth of his soul.WithKate Cooper Professor of History at the University of London and Head of History at Royal HollowayMorwenna Ludlow Professor of Christian History and Theology at the University of Exeterand Martin Palmer Visiting Professor in Religion, History and Nature at the University of WinchesterProducer: Simon Tillotson.

Melvyn Bragg and guests discuss how and why Highlanders and Islanders were cleared from their homes in waves in C18th and C19th, following the break up of the Clans after the Battle of Culloden. Initially, landlords tried to keep people on their estates for money-making schemes, but the end of the Napoleonic Wars brought convulsive changes. Some of the evictions were notorious, with the sudden and fatal burning of townships, to make way for sheep and deer farming. For many, migration brought a new start elsewhere in Britain or in the British colonies, while for some it meant death from disease while in transit. After more than a century of upheaval, the Clearances left an indelible mark on the people and landscape of the Highlands and Western Isles.The image above is a detail from a print of 'Lochaber No More' by John Watson Nicol 1856-1926With Sir Tom Devine Professor Emeritus of Scottish History at the University of EdinburghMarjory Harper Professor of History at the University of Aberdeen and Visiting Professor at the University of the Highlands and IslandsAndMurray Pittock Bradley Professor of English Literature and Pro Vice Principal at the University of GlasgowProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the ideas attributed to Sun Tzu (544-496BC, according to tradition), a legendary figure from the beginning of the Iron Age in China, around the time of Confucius. He may have been the historical figure Sun Wu, a military adviser at the court of King Helu of Wu (who reigned between about 514 and 496 BC), one of the kings in power in the Warring States period of Chinese history (6th - 5th century BC). Sun Tzu was credited as the author of The Art of War, a work on military strategy that soon became influential in China and then Japan both for its guidance on conducting and avoiding war and for its approach to strategy generally. After The Art of War was translated into European languages in C18th, its influence spread to military academies around the world.The image above is of a terracotta warrior from the tomb of Qin Shi Huang, the first Emperor, who unified China after the Warring States period.With Hilde De Weerdt Professor of Chinese History at Leiden UniversityTim Barrett Professor Emeritus of East Asian History at SOAS, University of LondonAndImre Galambos Reader in Chinese Studies at the University of CambridgeProducer: Simon Tillotson.
