The Evolution of Crocodiles

Melvyn Bragg and his guests discuss the sources for early Chinese history. The first attempts to make a record of historical events in China date from the Shang dynasty of the second millennium BC. The earliest surviving records were inscribed on bones or tortoise shells; in later centuries, chroniclers left detailed accounts on paper or silk. In the last hundred years, archaeologists have discovered a wealth of new materials, including a cache of previously unknown texts which were found in a sealed cave on the edge of the Gobi Desert. Such sources are are shedding new light on Chinese history, although interpreting ancient sources from the period before the invention of printing presents a number of challenges.With:Roel Sterckx Joseph Needham Professor of Chinese History at the University of CambridgeTim Barrett Professor of East Asian History at SOAS, University of LondonHilde de Weerdt Professor of Chinese History at Leiden UniversityProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Battle of Tours. In 732 a large Arab army invaded Gaul from northern Spain, and travelled as far north as Poitiers. There they were defeated by Charles Martel, whose Frankish and Burgundian forces repelled the invaders. The result confirmed the regional supremacy of Charles, who went on to establish a strong Frankish dynasty. The Battle of Tours was the last major incursion of Muslim armies into northern Europe; some historians, including Edward Gibbon, have seen it as the decisive moment that determined that the continent would remain Christian.With:Hugh Kennedy Professor of Arabic at SOAS, University of LondonRosamond McKitterick Professor of Medieval History at the University of CambridgeMatthew Innes Vice-Master and Professor of History at Birkbeck, University of London.

Melvyn Bragg and his guests discuss Plato's Symposium, one of the Greek philosopher's most celebrated works. Written in the 4th century BC, it is a dialogue set at a dinner party attended by a number of prominent ancient Athenians, including the philosopher Socrates and the playwright Aristophanes. Each of the guests speaks of Eros, or erotic love. This fictional discussion of the nature of love, how and why it arises and what it means to be in love, has had a significant influence on later thinkers, and is the origin of the modern notion of Platonic love.With:Angie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldRichard Hunter Regius Professor of Greek at the University of CambridgeFrisbee Sheffield Director of Studies in Philosophy at Christ's College, University of Cambridge.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Medici family, who dominated Florence's political and cultural life for three centuries. The House of Medici came to prominence in Italy in the fifteenth century as a result of the wealth they had built up through banking. With the rise of Cosimo de' Medici, they became Florence's most powerful and influential dynasty, effectively controlling the city's government. Their patronage of the arts turned Florence into a leading centre of the Renaissance and the Medici Bank was one of the most successful institutions of its day. As well as producing four popes, members of the House of Medici married into various European royal families.With:Evelyn Welch Professor of Renaissance Studies at King's College, University of LondonRobert Black Professor of Renaissance History at the University of LeedsCatherine Fletcher Lecturer in Public History at the University of SheffieldProducer: Victoria Brignell.

Melvyn Bragg and his guests discuss complexity and how it can help us understand the world around us. When living beings come together and act in a group, they do so in complicated and unpredictable ways: societies often behave very differently from the individuals within them. Complexity was a phenomenon little understood a generation ago, but research into complex systems now has important applications in many different fields, from biology to political science. Today it is being used to explain how birds flock, to predict traffic flow in cities and to study the spread of diseases.With:Ian Stewart Emeritus Professor of Mathematics at the University of WarwickJeff Johnson Professor of Complexity Science and Design at the Open UniversityProfessor Eve Mitleton-Kelly Director of the Complexity Research Group at the London School of Economics.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the life and work of Pliny the Younger, famous for his letters. A prominent lawyer in Rome in the first century AD, Pliny later became governor of the province of Bithynia, on the Black Sea coast of modern Turkey. Throughout his career he was a prolific letter-writer, sharing his thoughts with great contemporaries including the historian Tacitus, and asking the advice of the Emperor Trajan. Pliny's letters offer fascinating insights into life in ancient Rome and its empire, from the mundane details of irrigation schemes to his vivid eyewitness account of the eruption of Vesuvius.With:Catharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonRoy Gibson Professor of Latin at the University of ManchesterAlice König Lecturer in Latin and Classical Studies at the University of St AndrewsProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Hindu ideas about Creation. According to most Western religious traditions, a deity was the original creator of the Universe. Hinduism, on the other hand, has no single creation story. For thousands of years, Hindu thinkers have taken a variety of approaches to the question of where we come from, with some making the case for divine intervention and others asking whether it is even possible for humans to comprehend the nature of creation. The origin of our existence, and the nature of the Universe we live in, is one of the richest strands of Hindu thought.With:Jessica Frazier Lecturer in Religious Studies at the University of Kent and a Research Fellow of the Oxford Centre for Hindu Studies at the University of OxfordChakravarthi Ram-Prasad Professor of Comparative Religion and Philosophy at Lancaster UniversityGavin Flood Professor of Hindu Studies and Comparative Religion at the University of Oxford.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the development of the microscope, an instrument which has revolutionised our knowledge of the world and the organisms that inhabit it. In the seventeenth century the pioneering work of two scientists, the Dutchman Antonie van Leeuwenhoek and Robert Hooke in England, revealed the teeming microscopic world that exists at scales beyond the capabilities of the naked eye. The microscope became an essential component of scientific enquiry by the nineteenth century, but in the 1930s a German physicist, Ernst Ruska, discovered that by using a beam of electrons he could view structures much tinier than was possible using visible light. Today light and electron microscopy are among the most powerful tools at the disposal of modern science, and new techniques are still being developed.With:Jim Bennett Visiting Keeper at the Science Museum in LondonSir Colin Humphreys Professor of Materials Science and Director of Research at the University of CambridgeMichelle Peckham Professor of Cell Biology at the University of LeedsProducer: Thomas Morris.
