Melvyn Bragg and his guests discuss the life and work of Benjamin Franklin. A printer, statesman, diplomat, writer and scientist, Franklin was one of the most remarkable individuals of the eighteenth century. His discoveries relating to the nature of electricity, and in particular a celebrated experiment which involved flying a kite in a thunderstorm, made him famous in Europe and America. His inventions include bifocal spectacles, and a new type of stove. In the second half of his life he became prominent as a politician and a successful diplomat. As the only Founding Father to have signed all three of the fundamental documents of the United States of America, including its Declaration of Independence and Constitution, Benjamin Franklin occupies a unique position in the history of the nation.

Melvyn Bragg and his guests discuss the physics of electrical conduction. Although electricity has been known for several hundred years, it was only in the early twentieth century that physicists first satisfactorily explained the phenomenon. Electric current is the passage of charged particles through a medium - but a material will only conduct electricity if its atomic structure enables it to do so. In investigating electrical conduction scientists discovered two new classes of material. Semiconductors, first exploited commercially in the 1950s, have given us the transistor, the solar cell and the silicon chip, and have revolutionised telecommunications. And superconductors, remarkable materials first observed in 1911, are used in medical imaging and at the Large Hadron Collider in Geneva.

Melvyn Bragg and his guests discuss the An Lushan Rebellion, a major uprising against the imperial rule of the Chinese Tang Dynasty. In 755 AD a senior general, An Lushan, orchestrated a plot against Emperor Xuanzong, taking the regime's capital city before declaring a rival dynasty in northern China. The rebellion lasted eight years but was eventually put down by Tang forces. Although the dynasty's authority was restored, it never regained the prosperity of previous generations. The An Lushan Rebellion displaced millions of people and killed many more. It changed the relationship between the Chinese state and neighbouring powers; but it also left a rich cultural legacy in the poetry memorialising this seismic event.With:Frances WoodLead Curator of Chinese at the British LibraryNaomi StandenProfessor of Medieval History at the University of BirminghamHilde de WeerdtFellow and Lecturer in Chinese History at Pembroke College, Oxford.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the life and work of the Dutch humanist scholar Desiderius Erasmus. In his lifetime Erasmus was almost universally recognised as the greatest classical scholar of his age, the translator and editor of numerous Latin and Greek texts. But above all he was a religious scholar who published important editions of the Bible which expunged many corruptions to the texts of the Scriptures. He was an outspoken critic of the Church, whose biting satire on its excesses, In Praise of Folly, was famed throughout Europe.When the Reformation began in 1517, however, Erasmus chose to remain a member of the Catholic Church rather than side with Martin Luther and the reformers, and a few years later he engaged in a celebrated debate with Luther on the subject of free will. Through his writings on the Church, on education and the wide gamut of humanist scholarship, Erasmus is remembered today as one of the greatest thinkers of the northern Renaissance.With:Diarmaid MacCullochProfessor of the History of the Church at the University of OxfordEamon DuffyProfessor of the History of Christianity at the University of CambridgeJill KrayeProfessor of the History of Renaissance Philosophy and Librarian at the Warburg Institute, University of London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Kama Sutra, one of the most celebrated and often misunderstood texts of Indian literature. Probably composed during the reign of the Gupta dynasty around 1800 years ago, the work is a collection of writings about the art of love and sensual pleasure. Although it is best known today for a single chapter devoted to sexual pleasure, this important Sanksrit collection contains much besides. In particular it teaches the attainment of Kama (pleasure), one of the central goals of Hinduism. The Kama Sutra is a manual to a life of fulfilment, offering advice on such subjects as finding a spouse and how to behave in marriage; it has had a profound influence on Indian culture and thought.

Melvyn Bragg and his guests discuss the evolution of the Scientific Method, the systematic and analytical approach to scientific thought. In 1620 the great philosopher and scientist Francis Bacon published the Novum Organum, a work outlining a new system of thought which he believed should inform all enquiry into the laws of nature. Philosophers before him had given their attention to the reasoning that underlies scientific enquiry; but Bacon's emphasis on observation and experience is often seen today as giving rise to a new phenomenon: the scientific method.The scientific method, and the logical processes on which it is based, became a topic of intense debate in the seventeenth century, and thinkers including Isaac Newton, Thomas Huxley and Karl Popper all made important contributions. Some of the greatest discoveries of the modern age were informed by their work, although even today the term 'scientific method' remains difficult to define.With: Simon SchafferProfessor of the History of Science at the University of CambridgeJohn WorrallProfessor of the Philosophy of Science at the London School of Economics and Political ScienceMichela MassimiSenior Lecturer in the Philosophy of Science at University College London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss 1848, the year that saw Europe engulfed in revolution. Across the continent, from Paris to Palermo, liberals rose against conservative governments. The first stirrings of rebellion came in January, in Sicily; in February the French monarchy fell; and within a few months Germany, Austria, Hungary and Italy had all been overtaken by revolutionary fervour. Only a few countries, notably Britain and Russia, were spared.The rebels were fighting for nationalism, social justice and civil rights, and were prepared to fight in the streets down to the last man. Tens of thousands of people lost their lives; but little of lasting value was achieved, and by the end of the year the liberal revolutions had been soundly beaten.With: Tim BlanningEmeritus Professor of History at the University of CambridgeLucy RiallProfessor of History at Birkbeck, University of LondonMike RapportSenior Lecturer in History at the University of Stirling.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Safavid Dynasty, rulers of the Persian empire between the 16th and 18th centuries.In 1501 Shah Ismail, a boy of fifteen, declared himself ruler of Azerbaijan. Within a year he had expanded his territory to include most of Persia, and founded a ruling dynasty which was to last for more than two hundred years. At the peak of their success the Safavids ruled over a vast territory which included all of modern-day Iran. They converted their subjects to Shi'a Islam, and so created the religious identity of modern Iran - although they were also often ruthless in their suppression of Sunni practices. They thrived on international trade, and their capital Isfahan, rebuilt by the visionary Shah Abbas, became one of the most magnificent cities in the world. Under Safavid rule Persia became a cultural centre, producing many great artists and thinkers.
