In Our Time

Melvyn Bragg and guests discusses the life and ideas of James Clerk Maxwell whose work is not widely known, but whose genius and contribution to the age in which we live is enormous.He took the first colour photograph, defined the nature of gases and with a few mathematical equations expressed all the fundamental laws of light, electricity and magnetism - and in doing so he provided the tools to create the technological age, from radar to radio and televisions to mobile phones. He is credited with fundamentally changing our view of reality, so much so that Albert Einstein said, “One scientific epoch ended and another began with James Clerk Maxwell”. But who was James Clerk Maxwell? What were his ideas, and does this nineteenth century ‘natural philosopher’ deserve a place alongside Newton and Einstein in the pantheon of science? With Simon Schaffer, Reader in History and Philosophy of Science at the University of Cambridge; Peter Harman, Professor of the History of Science at Lancaster University and editor of The Scientific Letters and Papers of James Clerk Maxwell; Joanna Haigh, Professor of Atmospheric Physics at Imperial College London.

Melvyn Bragg and guests discuss the Apocalypse. George Bernard Shaw dismissed it as “the curious record of the visions of a drug addict” and if the Orthodox Christian Church had had its way, it would never have made it into the New Testament. But the Book of Revelation was included and its images of apocalypse, from the Four Horsemen to the Whore of Babylon, were fixed into the Christian imagination and its theology. As well as providing abundant imagery for artists from Durer to Blake, ideas of the end of the world have influenced the response to political, social and natural upheavals throughout history. Our understanding of history itself owes much to the apocalyptic way of thinking. But how did this powerful narrative of judgement and retribution evolve, and how does it still shape our thinking on the deepest questions of morality and history? With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Marina Benjamin, journalist and author of Living at the End of the World; Justin Champion, Reader in the History of Early Modern Ideas at Royal Holloway College, University of London.

Melvyn Bragg and guests discuss the attempt to define humanity’s part in the natural world. In Childe Harold’s Pilgrimage Lord Byron wrote:“There is a pleasure in the pathless woods, There is a rapture on the lonely shore,There is society where none intrudes,By the deep Sea, and music in its roar:I love not man the less, but Nature more.” In the Bible’s book of Genesis, ‘nature’ was the paradise of Eden, but for the philosopher Thomas Hobbes it was a place of perpetual war, where the life of man was “solitary, poore, nasty, brutish and short”. The defining of Nature, whether “red in tooth and claw” or as the fount of all innocence, is an attempt to define man’s origins and purpose and humanity’s part in the natural world. With Jonathan Bate, Professor of English Literature at the University of Warwick; Roger Scruton, Professor of Philosophy at the University of Buckingham; Karen Edwards, Lecturer in English at the University of Exeter.

Melvyn Bragg and guests discuss the formation of volcanoes. In 79AD Mount Vesuvius erupted on the Bay of Naples, buried Pompeii in ash and drowned nearby Herculaneum in lava. The great letter writer Pliny the Younger was staying with his uncle in Misenum and was a witness to the cataclysm. He described it to the historian Tacitus, It seemed as though the sea was being sucked backwards, as if it were being pushed back by the shaking of the land. Certainly the shoreline moved outwards, and many sea creatures were left on dry sand. Behind us were frightening dark clouds, rent by lightning twisted and hurled, opening to reveal huge figures of flame. These were like lightning but bigger. This eruption, which claimed the life of Pliny's uncle, is one of about 500 volcanoes to have erupted in the last two thousand years, some of which are now categorised by vulcanologists as Plinian, after Pliny's famous description.What causes volcanoes? What role do they play in the formation and maintenance of our planet? And is it ever possible to predict when and where they are about to erupt?With Hilary Downes, Professor of Geochemistry at Birkbeck, University of London; Steve Self, Professor of Vulcanology at the Open University; Bill McGuire, Benfield Professor of Geophysical Hazards at University College London.

Melvyn Bragg and guests discuss the private trading company that helped forge the British Empire. At its peak, its influence stretched from western India to eastern China via the farthest reaches of the Indonesian archipelago. It had a fleet of 130 twelve hundred tonne ships and commanded an army of 200,000 troops that came to dominate the Indian subcontinent. It funded governments, toppled princes and generated spectacular amounts of money from trading textiles and spices. But this wasn’t an empire, it wasn’t even a state, it was a company. The East India Company, founded in 1600, lasted for 258 years before the British state gained full control of its activities. In that time it had redrawn the map of India, built an empire and reinvented the fashions and the foodstuffs of Britain. But how did the East India Company become so powerful? How did it change both India and Britain and how was the idea of a company running a country ever accepted by the British Crown?With Huw Bowen, Senior Lecturer in Economic and Social History at the University of Leicester; Linda Colley, School Professor of History at the London School of Economics; Maria Misra, Fellow and Tutor in Modern History at Keble College, Oxford.

Melvyn Bragg and guests discuss the British aristocracy. The Greeks gave us the word aristocracy; it takes its root from ‘aristo’, meaning best and ‘kratos’, meaning rule or power. And for more than five hundred years Britain was ruled by a class that was defined, at the time, as the best. They founded their ascendancy on the twin pillars of land and heredity and in terms of privilege, preferment, power, style and wealth, they dominated British society. As the Earl of Chesterfield confidently informed the House of Lords in the mid-18th century, “We, my lords, may thank heaven that we have something better than our brains to depend upon”. What made the British Aristocracy the one of the most successful power elites in the world? And what brought about its decline?With David Cannadine, Director of the University of London’s Institute of Historical Research and author of The Decline and Fall of the British Aristocracy; Rosemary Sweet, Lecturer in History at the University of Leicester; Felipe Fernandez-Armesto, Professorial Research Fellow at Queen Mary, University of London.

Melvyn Bragg and guests discuss the history and philosophy of warfare. The British historian Edward Gibbon wrote: “Every age, however destitute of science or virtue, sufficiently abounds with acts of blood and military renown.” War, it seems, is one of mankind’s most constant companions, one that has blighted the lives and troubled the minds of men and women from antiquity onwards. Plato envisaged a society without war, but found it had no arts, no culture and no political system. In our own time the United Nations struggles but often fails to prevent the outbreak of conflict. But how has war been understood throughout the ages? Who has it served and how has it been justified? Is war inherent to human beings or could society be organised to the exclusion of all conflict?With Sir Michael Howard, Emeritus Professor of Modern History at the University of Oxford; Angie Hobbs, Lecturer in Philosophy at the University of Warwick; Jeremy Black, Professor of History at the University of Exeter.

Melvyn Bragg and guests discuss the Lunar Society. In the late 18th century, with the ascendant British Empire centred on London, a small group of friends met at a house on the crossroads outside Birmingham and applied their minds to the problems of the age. Between them they managed to launch the Industrial Revolution, discover oxygen, harness the power of steam and pioneer the theory of evolution. They were the Lunar Society, a gathering of free and fertile minds centred on the remarkable quartet of Matthew Boulton, James Watt, Joseph Priestly and Erasmus Darwin. The potter Josiah Wedgwood, another member, summed up the ethos of this group when he said that they were ‘living in an age of miracles in which anything could be achieved’.But how did the Lunar Society operate? What was the blend of religious dissent, entrepreneurial spirit and intellectual adventure that proved so fertile and how did their discoveries permanently change the shape and character of this country?With Simon Schaffer, Reader in History and Philosophy of Science at the University of Cambridge; Jenny Uglow, Honorary Visiting Professor at the University of Warwick and author of The Lunar Men: The Friends who Made the Future; Peter Jones, Professor of French History at the University of Birmingham.

Melvyn Bragg and guests discuss the function and significance of memory. The great writer of remembrance, Marcel Proust, declared “We are able to find everything in our memory, which is like a dispensary or chemical laboratory in which chance steers our hand, sometimes to a soothing drug and sometimes to a dangerous poison”. The memory is vital to life and without it we could not be the people we are, but can it really contain the sum of all our experience? Is it a repository constantly mounting events waiting to be plucked to consciousness, or if not, then under what criteria are memories turfed out?With Martin Conway, Professor of Psychology at Durham University; Mike Kopelman, Professor of Neuropsychiatry at King's College London and St Thomas’ Hospital; Kim Graham, Senior Scientist at the Medical Research Council’s Cognition and Brain Sciences Unit.

Melvyn Bragg and guests discuss blood. For more than 1500 years popular imagination, western science and the Christian Church colluded in a belief that blood was the link between the human and the divine. The Greek physician, Galen, declared that it was blood that contained the force of life and linked the body to the soul, the Christian Church established The Eucharist – the taking of the body and blood of Christ. In our blood was our individuality, it was thought, our essence and our blood lines were special. Transfusion threatened all that and now itself is being questioned.Why is it that blood was used to define both man and messiah? And how has the tradition of blood in religious thought been affected by the progress of medicine?With Miri Rubin, Professor of European History at Queen Mary, University of London; Dr Anne Hardy, Reader in the History of Medicine at the Wellcome Trust Centre for the History of Medicine at University College London; Jonathan Sawday, Professor of English Studies at the University of Strathclyde.
