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 secure credit card transactions are possible.With:Marcus du SautoyProfessor of Mathematics at the University of OxfordColva Roney-DougalSenior Lecturer in Pure Mathematics at the University of St AndrewsTimothy GowersRoyal Society Research Professor in Mathematics at the University of CambridgeProducer: Thomas Morris.

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 University of Arkansas.Producer: Thomas Morris.

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.

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 this ancient and complex religion come to be so influential?With:Tim Barrett Professor of East Asian History at the School of Oriental and African Studies, University of LondonMartin PalmerDirector of the International Consultancy on Religion, Education and CultureHilde De WeerdtFellow and Tutor in Chinese History at Pembroke College, University of Oxford Producer: Natalia Fernandez.

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, University of CambridgeKathleen BurkProfessor of History, University College LondonIwan MorusReader in History, University of AberystwythProducer: Thomas Morris.

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 Modern Literature and Theory at Birkbeck, University of LondonTom HealyProfessor of Renaissance Studies at the University of SussexJulie SandersProfessor of English Literature and Drama at the University of NottinghamProducer: Thomas Morris.
