The Evolution of Crocodiles

Melvyn Bragg and guests discuss pastoral literature.Come live with me and be my love, And we will all the pleasures prove That valleys, groves, hills, and fields, Woods or steepy mountain yields.And we will sit upon the rocks, Seeing the shepherds feed their flocks, By shallow rivers to whose falls Melodious birds sing madrigals. An entreaty from Christopher Marlowe's Passionate Shepherd to His Love - thought by many to be the crowning example of Elizabethan pastoral poetry. The traditions of pastoral poetry, literature and drama can be traced back to the third century BC and have principally offered a conventionalised picture of rural life, the naturalness and innocence of which is seen to contrast favourably with the corruption and artificialities of city and court life. Pastoral literature deals with tensions between nature and art, the real and the ideal, the actual and the mythical, and although pastoral works have been written from the point of view of shepherds or rustics, they have often been penned by highly sophisticated, urban poets and playwrights. But to what extent does pastoral literature represent a continuous yearning for a non-existent Golden Age of Innocence? How far did it evolve to reflect the social and political preoccupations of its times and what were the real meanings of its much used metaphors of town and country? With Helen Cooper, Professor of Medieval and Renaissance English at the University of Cambridge; Laurence Lerner, former Professor of English at the University of Sussex; Julie Sanders, Professor of English Literature and Drama at the University of Nottingham.

Melvyn Bragg and guests discuss the galaxies. Spread out across the voids of space like spun sugar, but harbouring in their centres super-massive black holes. Our galaxy is about 100,000 light years across, is shaped like a fried egg and we travel inside it at approximately 220 kilometres per second. The nearest one to us is much smaller and is nicknamed the Sagittarius Dwarf. But the one down the road, called Andromeda, is just as large as ours and, in 10 billion years, we'll probably crash into it. Galaxies - the vast islands in space of staggering beauty and even more staggering dimension. But galaxies are not simply there to adorn the universe; they house much of its visible matter and maintain the stars in a constant cycle of creation and destruction. But why do galaxies exist, how have they evolved and what lies at the centre of a galaxy to make the stars dance round it at such colossal speeds? With John Gribbin, Visiting Fellow in Astronomy at the University of Sussex; Carolin Crawford, Royal Society University Research Fellow at the Institute of Astronomy at Cambridge; Robert Kennicutt, Plumian Professor of Astronomy and Experimental Philosophy at the University of Cambridge.

Melvyn Bragg and guests discuss the Spanish Inquisition, the defenders of medieval orthodoxy. The word ‘Inquisition’ has its roots in the Latin word 'inquisito' which means inquiry. The Romans used the inquisitorial process as a form of legal procedure employed in the search for evidence. Once Rome's religion changed to Christianity under Constantine, it retained the inquisitorial trial method but also developed brutal means of dealing with heretics who went against the doctrines of the new religion. Efforts to suppress religious freedom were initially ad hoc until the establishment of an Office of Inquisition in the Middle Ages, founded in response to the growing Catharist heresy in South West France. The Spanish Inquisition set up in 1478 surpassed all Inquisitorial activity that had preceded it in terms of its reach and length. For 350 years under Papal Decree, Jews, then Muslims and Protestants were put through the Inquisitional Court and condemned to torture, imprisonment, exile and death. How did the early origins of the Inquisition in Medieval Europe spread to Spain? What were the motivations behind the systematic persecution of Jews, Muslims and Protestants? And what finally brought about an end to the Spanish Inquisition 350 years after it had first been decreed? With John Edwards, Research Fellow in Spanish at the University of Oxford; Alexander Murray, Emeritus Fellow in History at University College, Oxford;Michael Alpert, Emeritus Professor in Modern and Contemporary History of Spain at the University of Westminster

Melvyn Bragg and guests discuss Carbon. It forms the basis of all organic life and has the amazing ability to bond with itself and a wide range of other elements, forming nearly 10 million known compounds. It is in the food we eat, the clothes we wear, the shampoo we use and the petrol that fuels our cars. Because carbon has the largest range of subtle bonding capabilities, 95% of everything that exists in the universe is made up of carbon atoms that are stuck together. It is an extraordinary element for many reasons: the carbon-nitrogen cycle provides some of the energy produced by the Sun and the stars; it has the highest melting point of all the elements; and its different forms include one of the softest and one of the hardest substances known. What gives carbon its great ability to bond with other atoms? What is the significance of the recent discovery of a new carbon molecule - the C60? What role does carbon play in the modern chemistry of nanotechnology? And how should we address the problem of our diminishing carbon energy sources? With Harry Kroto, Professor of Chemistry at Florida State University; Monica Grady, Professor of Planetary and Space Sciences at the Open University; Ken Teo, Royal Academy of Engineering Research Fellow at Cambridge University.

Melvyn Bragg and guests discuss the anti slavery novel, 'Uncle Tom's Cabin'. When Abraham Lincoln met the writer Harriet Beecher Stowe after the start of the American Civil War, he reportedly said to her: 'So you're the little lady whose book started this big war'. Stowe's novel Uncle Tom's Cabin, published in 1852, is credited as fuelling the cause to abolish slavery in the northern half of the United States in direct response to its continuation in the South. The book deals with the harsh reality of slavery and the enduring power of Christian faith. It proved to be the bestselling novel of the 19th century, outselling the Bible in its first year of publication. Its fame spread internationally, No other book had portrayed an African-American slave as a central figure who was heroic and Christ-like. Lord Palmerston praised it highly and Tolstoy reportedly said it was his favourite novel. What impact did Uncle Tom's Cabin have on the on the Civil War and the abolition of slavery in 19th century America? How did the book create stereotypes about African Americans, many of which endure to this day? And what was its literary legacy? With Dr Celeste-Marie Bernier, Lecturer in American Studies at the University of Nottingham; Dr Sarah Meer, Lecturer and Director of Studies in English at Selwyn College, University of Cambridge; Dr Clive Webb, Reader in American History at the University of Sussex.

Melvyn Bragg and guests discuss the heart. Aristotle considered the heart to be the seat of thought, reason and emotion. The Roman physician Galen located the seat of the passions in the liver, the seat of reason in the brain, and considered the heart to be the seat of the emotions. It was not until the 17th century that the physician William Harvey wrote in the preface to his thesis On the Motion of the Heart and Blood in Animals, a letter addressed to King Charles I. 'The heart of animals is the foundation of their life, the sovereign of everything within them...from which all power proceeds. The King, in like manner, is the foundation of his kingdom, the sun of the world around him, the heart of the republic, the foundation whence all power, all grace doth flow'. Harvey was probably wise to address the King in this manner, for what he laid out in his groundbreaking text challenged scientific wisdom that had gone unquestioned for centuries about the true function of the heart. Organs had been seen in a hierarchical structure with the heart as the pinnacle. But Harvey transformed the metaphor into something quite different: the heart as a mechanistic pumping device. How had the Ancient Greeks and Islamic physicians understood the heart? What role did the bodily humours play in this understanding? Why has the heart always been seen as the seat of emotion and passion? And why was it that despite Harvey's discoveries about the heart and its function, this had limited implications for medical therapy and advancement?

Melvyn Bragg and guests discuss the mathematical structures that lie within the heart of music. The seventeenth century philosopher Gottfried Leibniz wrote: 'Music is the pleasure the human mind experiences from counting without being aware that it is counting'. Mathematical structures have always provided the bare bones around which musicians compose music and have been vital to the very practical considerations of performance such as fingering and tempo. But there is a more complex area in the relationship between maths and music which is to do with the physics of sound: how pitch is determined by force or weight; how the complex arrangement of notes in relation to each other produces a scale; and how frequency determines the harmonics of sound. How were mathematical formulations used to create early music? Why do we in the West hear twelve notes in the octave when the Chinese hear fifty-three? What is the mathematical sequence that produces the so-called 'golden section'? And why was there a resurgence of the use of mathematics in composition in the twentieth century? With Marcus du Sautoy, Professor of Mathematics at the University of Oxford; Robin Wilson, Professor of Pure Mathematics at the Open University; Ruth Tatlow, Lecturer in Music Theory at the University of Stockholm.

Melvyn Bragg and guests discuss the great nineteenth century political philosopher John Stuart Mill. He believed that, 'The true philosophy is the marriage of poetry and logic'. He was one of the first thinkers to argue that a social theory must engage with ideas of culture and the internal life. He used Wordsworth to inform his social theory, he was a proto feminist and his treatise On Liberty is one of the sacred texts of liberalism. J S Mill believed that action was the natural articulation of thought. He battled throughout his life for social reform and individual freedom and was hugely influential in the extension of the vote. Few modern discussions on race, birth control, the state and human rights have not been influenced by Mill's theories. How did Mill's utilitarian background shape his political ideas? Why did he think Romantic literature was significant to the rational structure of society? On what grounds did he argue for women's equality? And how did his notions of the individual become central to modern social theory? With A C Grayling, Professor of Philosophy at Birkbeck, University of London; Janet Radcliffe Richards, Reader in Bioethics at University College London; Alan Ryan, Professor of Politics at Oxford University.
