Melvyn Bragg and his guests discuss the Bhagavad Gita.The Bhagavad Gita, a 700-verse section of the Sanskrit epic the Mahabharata, is one of the most revered texts of Hinduism. Written in around 200 BC, it narrates a conversation between Krishna, an incarnation of the deity, and the Pandava prince Arjuna. It has been described as a concise summary of Hindu theology, a short work which offers advice on how to live one's life.The Gita is also a philosophical work of great richness and influence. First translated into English in the 18th century, it was quickly taken up in the West. Its many admirers have included Mahatma Gandhi, whose passion for the work is one reason that the Bhagavad Gita became a key text for followers of the Indian Independence movement in the first half of the twentieth century.With:Chakravarthi Ram-PrasadProfessor of Comparative Religion and Philosophy at Lancaster UniversityJulius LipnerProfessor of Hinduism and the Comparative Study of Religion and Fellow of Clare Hall at the Universit

Melvyn Bragg and his guests discuss the dawn of the European Iron Age.In around 3000 BC European metalworkers started to make tools and weapons out of bronze. A complex trading network evolved to convey this valuable metal and other goods around the continent. But two millennia later, a new skill arrived from the Middle East: iron smelting. This harder, more versatile metal represented a huge technological breakthrough.The arrival of the European Iron Age, in around 1000 BC, was a time of huge social as well as technological change. New civilisations arose, the landscape was transformed, and societies developed new cultures and lifestyles. Whether this was the direct result of the arrival of iron is one of the most intriguing questions in archaeology.With:Sir Barry CunliffeEmeritus Professor of European Archaeology at the University of OxfordSue HamiltonProfessor of Prehistory at University College LondonTimothy ChampionProfessor of Archaeology at the University of SouthamptonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the medieval universities.In the 11th and 12th centuries a new type of institution started to appear in the major cities of Europe. The first universities were those of Bologna and Paris; within a hundred years similar educational organisations were springing up all over the continent. The first universities based their studies on the liberal arts curriculum, a mix of seven separate disciplines derived from the educational theories of Ancient Greece. The universities provided training for those intending to embark on careers in the Church, the law and education. They provided a new focus for intellectual life in Europe, and exerted a significant influence on society around them. And the university model proved so robust that many of these institutions and their medieval innovations still exist today.With:Miri RubinProfessor of Medieval and Early Modern History at Queen Mary, University of LondonIan WeiSenior Lecturer in Medieval European History at the University of Bristol

In the 500th edition of the programme, Melvyn Bragg and his guests discuss the philosophical idea of free will.Free will - the extent to which we are free to choose our own actions - is one of the most absorbing philosophical problems, debated by almost every great thinker of the last two thousand years. In a universe apparently governed by physical laws, is it possible for individuals to be responsible for their own actions? Or are our lives simply proceeding along preordained paths? Determinism - the doctrine that every event is the inevitable consequence of what goes before - seems to suggest so.Many intellectuals have concluded that free will is logically impossible. The philosopher Baruch Spinoza regarded it as a delusion. Albert Einstein wrote: "Human beings, in their thinking, feeling and acting are not free agents but are as causally bound as the stars in their motion." But in the Enlightenment, philosophers including David Hume found ways in which free will and determinism could be reconciled. Recent

Melvyn Bragg and his guests discuss the age of the Universe.Since the 18th century, when scientists first realised that the Universe had existed for more than a few thousand years, cosmologists have debated its likely age. The discovery that the Universe was expanding allowed the first informed estimates of its age to be made by the great astronomer Edwin Hubble in the early decades of the twentieth century. Hubble's estimate of the rate at which the Universe is expanding, the so-called Hubble Constant, has been progressively improved. Today cosmologists have a variety of other methods for ageing the Universe, most recently the detailed measurements of cosmic microwave background radiation - the afterglow of the Big Bang - made in the last decade. And all these methods seem to agree on one thing: the Universe has existed for around 13.75 billion years.With:Martin ReesAstronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of CambridgeCarolin CrawfordMember of the Institute of A

Melvyn Bragg and his guests discuss the Taiping Rebellion.In 1850 a Chinese Christian convert, Hong Xiuquan, proclaimed himself leader of a new dynasty, the Taiping Heavenly Kingdom. He and his followers marched against the ruling Qing dynasty, gathering huge support as they went. The ensuing civil war lasted fourteen years; around twenty million people lost their lives in a conflict which eventually involved European as well as Chinese soldiers. The Taiping Rebellion was arguably the most important event to befall China in the 19th century. Chinese nationalists and communists alike have been profoundly influenced by it, and historians believe it shaped modern China in the same way as the First World War shaped modern Europe.Rana MitterProfessor of the History and Politics of Modern China at the University of OxfordFrances WoodHead of the Chinese Section at the British LibraryJulia LovellLecturer in Chinese History at Birkbeck, University of London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the work and influence of Maimonides.Widely regarded as the greatest Jewish philosopher of the medieval period, Maimonides was also a physician and rabbinical authority. Also known as Rambam, his writings include a 14-volume work on Jewish law, the Mishneh Torah, which is still widely used today, and the Guide for the Perplexed, a central work of medieval philosophy. Although undoubtedly a titan of Jewish intellectual history, Maimonides was also profoundly influenced by the Islamic world. He exerted a strong influence on later Islamic philosophy, as well as on thinkers ranging from Thomas Aquinas to Leibniz and Newton.With:John HaldaneProfessor of Philosophy at the University of St AndrewsSarah StroumsaAlice and Jack Ormut Professor of Arabic Studies and currently Rector at the Hebrew University of JerusalemPeter AdamsonProfessor of Ancient and Medieval Philosophy at King's College London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the nervous system.Most animals have a nervous system, a network of nerve tissues which allows parts of the body to communicate with each other. In humans the most significant parts of this network are the brain, spinal column and retinas, which together make up the central nervous system. But there is also a peripheral nervous system, which enables sensation, movement and the regulation of the major organs.Scholars first described the nerves of the human body over two thousand years ago. For 1400 years it was believed that they were animated by 'animal spirits', mysterious powers which caused sensation and movement. In the eighteenth century scientists discovered that nerve fibres transmitted electrical impulses; it was not until the twentieth century that chemical agents - neurotransmitters - were first identified.With:Colin Blakemore Professor of Neuroscience at the University of OxfordVivian Nutton Emeritus Professor of the History of Medicine at University College, Lon

Melvyn Bragg and his guests discuss the Battle of Bannockburn.On June 23rd 1314, Scottish forces under their king Robert the Bruce confronted a larger army commanded by the English monarch Edward II at Bannockburn. It was the culmination of a war of independence which had been going on since the English had invaded Scotland in 1296. After eighteen years of intermittent fighting the English had been all but expelled from Scotland: their last stronghold was the castle at Stirling.The Scots won a decisive victory at Bannockburn. The English were routed and their king narrowly escaped capture. Although it took a further 14 years for Scotland to achieve full independence with the 1328 Treaty of Edinburgh-Northampton, this was an important triumph; today it remains one of the most discussed moments in the nation's history.With:Matthew StricklandProfessor of Medieval History at the University of GlasgowFiona WatsonHonorary Research Fellow in History at the University of DundeeMichael BrownReader in History at the Un

Melvyn Bragg and his guests discuss Aristotle's Poetics. The Poetics is, as far as we know, the first ever work of literary theory. Written in the 4th century BC, it is the work of a scholar who was also a biologist, and treats literary works with the detached analytical eye of a scientist. Aristotle examines drama and epic poetry, and how they achieve their effects; he analyses tragedy and the ways in which it plays on our emotions. Many of the ideas he articulates, such as catharsis, have remained in our critical vocabulary ever since. The book also contains an impassioned defence of poetry, which had been attacked by other thinkers, including Aristotle's own teacher Plato.Translated by medieval Arab scholars, the Poetics was rediscovered in Europe during the Renaissance and became a playwriting manual for many dramatists of the era. Today it remains a standard text for would-be Hollywood screenwriters.With:Angie HobbsAssociate Professor of Philosophy and Senior Fellow in the Public Understanding of Philoso

Melvyn Bragg and his guests discuss the Mexican Revolution.In 1908 the President of Mexico, Porfirio Diaz, gave an interview to an American journalist. He was 77 and had ruled the country in autocratic fashion for over thirty years. He discussed the country's economic development and spoke of his intention to retire to his country estate after overseeing a transition to multiparty democracy.Things did not turn out quite like that. Two years later Diaz was toppled by a popular uprising. It was the beginning of a tumultuous decade in which different factions fought for supremacy, and power changed hands many times. The conflict completely changed the face of the country, and resulted in the emergence of Mexico's most celebrated folk hero: Emiliano Zapata.With:Alan KnightProfessor of the History of Latin America at the University of OxfordPaul GarnerCowdray Professor of Spanish at the University of LeedsPatience SchellSenior Lecturer in Latin American Cultural Studies at the University of Manchester.

Melvyn Bragg and his guests discuss randomness and pseudorandomness.Randomness is the mathematics of the unpredictable. Dice and roulette wheels produce random numbers: those which are unpredictable and display no pattern. But mathematicians also talk of 'pseudorandom' numbers - those which appear to be random but are not. In the last century random numbers have become enormously useful to statisticians, computer scientists and cryptographers. But true randomness is difficult to find, and mathematicians have devised many ingenious solutions to harness or simulate it. These range from the Premium Bonds computer ERNIE (whose name stands for Electronic Random Number Indicator Equipment) to new methods involving quantum physics.Digital computers are incapable of behaving in a truly random fashion - so instead mathematicians have taught them how to harness pseudorandomness. This technique is used daily by weather forecasters, statisticians, and computer chip designers - and it's thanks to pseudorandomness that sec

Melvyn Bragg and his guests discuss Byron's poem Childe Harold's Pilgrimage.In 1812 the 24-year-old Lord Byron published the first part of a long narrative poem. It caused an instant sensation. "I awoke one morning and found myself famous", wrote Byron in his memorandum book, and the first edition sold out in three days. The poem narrates the life of an aristocrat on a grand tour of Europe. Its central character is the first Byronic hero, a flawed but charismatic young man modelled on the poet.As well as offering a self-portrait of Byron as a young man, Childe Harold is a fascinating snapshot of Europe at the beginning of the nineteenth century, a place ravaged by revolution and war; the poem also gives us an insight into the political and intellectual concerns of its author.With:Jonathan BateProfessor of English Literature at the University of WarwickJane StablerReader in Romanticism at the University of St AndrewsEmily Bernhard JacksonAssistant Professor in Nineteenth-Century English Literature at the Unive

Melvyn Bragg and his guests discuss the far-reaching consequences of the Industrial Revolution. After more than a century of rapid technological change, and the massive growth of its urban centres, Britain was changed forever. Lifestyles changed as workers moved from agricultural settlements to factory towns: health, housing and labour relations were all affected. But the effects were both social and intellectual, as thinkers originated theories to deal with the new realities of urban living, mass production and a consumer society. With:Jane HumphriesProfessor of Economic History and Fellow of All Souls College, University of OxfordEmma GriffinSenior Lecturer in History at the University of East AngliaLawrence GoldmanFellow and Tutor in History at St Peter's College, University of OxfordProducer: Thomas Morris.

In the first of two programmes, Melvyn Bragg and his guests discuss the Industrial Revolution.Between the middle of the eighteenth century and the early years of the nineteenth, Britain was transformed. This was a revolution, but not a political one: over the course of a few generations industrialisation swept the nation. Inventions such as the machine loom and the steam engine changed the face of manufacturing; cheap iron and steel became widely available; and vast new cities grew up around factory towns.All this had profound effects - not all of them positive - as an agrarian and primitive society was turned into an industrial empire, the richest nation on Earth. But why did this revolution take place here rather than abroad? And why did it begin in the first place?With:Jeremy BlackProfessor of History at the University of ExeterPat HudsonProfessor Emerita of History at Cardiff UniversityWilliam AshworthSenior Lecturer in History at the University of Liverpool.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss Daoism. An ancient Chinese tradition of philosophy and religious belief, Daoism first appeared more than two thousand years ago. For centuries it was the most popular religion in China; in the West its religious aspects are not as well known as its practices, which include meditation and Feng Shui, and for its most celebrated text, the Daodejing.The central aim in Daoism is to follow the 'Dao', a word which roughly translates as 'The Way'. Daoists believe in following life in its natural flow, what they refer to as an 'effortless action'. This transcendence can be linked to Buddhism, the Indian religion that came to China in the 2nd century BC and influenced Daoism - an exchange which went both ways. Daoism is closely related to, but has also at times conflicted with, the religion of the Chinese Imperial court, Confucianism. The spirit world is of great significance in Daoism, and its hierarchy and power often take precedence over events and people in real life. But how did

Melvyn Bragg and his guests discuss the innovations and influence of Thomas Edison, one of the architects of the modern age.Edison is popularly remembered as the man who made cheap electric light possible. Born in 1847, he began his career working in the new industry of telegraphy, and while still in his early twenties made major improvements to the technology of the telegraph. Not long afterwards he invented a new type of microphone which was used in telephones for almost a century. In the space of three productive years, Edison developed the phonograph and the first commercially viable light bulb and power distribution system. Many more inventions were to follow: he also played a part in the birth of cinema in the 1890s. When he died in 1931 he had patented no fewer than 1093 devices - the most prolific inventor in history. As the creator of the world's first industrial research laboratory he forever changed the way in which innovation took place.With:Simon SchafferProfessor of the History of Science, Unive

Melvyn Bragg and his guests discuss Cleopatra. The last pharaoh to rule Egypt, Cleopatra was a woman of intelligence and charisma, later celebrated as a great beauty. During an eventful life she was ousted from her throne and later restored to it with the help of her lover Julius Caesar. A later relationship with another Roman statesman, Mark Antony - and Cleopatra's subsequent death at her own hands - provided Shakespeare with the raw material for one of his greatest plays. Today Cleopatra is still an object of fascination, her story revealing as much about the Roman world as it does about the end of the age of the Pharaohs.With:Catharine EdwardsProfessor of Classics and Ancient History at Birkbeck, University of LondonMaria WykeProfessor of Latin at University College LondonSusan WalkerKeeper of Antiquities at the Ashmolean Museum at the University of OxfordProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the history of metaphor. In Shakespeare's As You Like It, the melancholy Jaques declares: "All the world's a stage/And all the men and women merely players." This is a celebrated use of metaphor, a figure of speech in which one thing is used to describe another. Metaphor is a technique apparently as old as language itself; it is present in the earliest surviving work of literature, the Epic of Gilgamesh. Homer developed it into an art form, and his invention of the epic simile was picked up by later writers including Milton. In the Middle Ages the device of allegory underpinned much of French and English writing, while the Metaphysical poets employed increasingly elaborate metaphorical conceits in the sixteenth century. In the age of the novel the metaphor once again evolved, while the Modernist writers used it to subvert their readers' expectations. But how does metaphor work, and what does this device tell us about the way our minds function?With:Steven ConnorProfessor of

Melvyn Bragg and his guests discuss John Foxe and his book Actes and Monuments, better known today as Foxe's Book of Martyrs. Born in 1517, John Foxe was an early Protestant who was forced to flee the persecutions which ensued when the Catholic Mary came to the English throne in 1553. He was a horrified observer on the Continent as more than three hundred of his countrymen were burnt at the stake. In exile he began work on a substantial work of scholarship, bringing together eyewitness accounts of these horrifying deaths.First published in 1563, Foxe's Book of Martyrs was one of the most elaborate early books produced, and thanks to vivid woodcut illustrations reached an audience far beyond the literate elite. Its stories of Protestant martyrdom became powerful Church propaganda in the late sixteenth century and were used by those who wished to banish Catholicism from England permanently. But despite its use as an instrument of religious factionalism, Foxe's work remains one of the key and most read books of
