Melvyn Bragg and his guests discuss the work of Alfred Russel Wallace, a pioneer of evolutionary theory. Born in 1823, Wallace travelled extensively, charting the distribution of animal species throughout the world. This fieldwork in the Amazon and later the Malay Archipelago led him to formulate a theory of evolution through natural selection. In 1858 he sent the paper he wrote on the subject to Charles Darwin, who was spurred into the writing and publication of his own masterpiece On the Origi...

Melvyn Bragg and his guests discuss the life and work of Anton Chekhov. Born in 1860, Chekhov trained as a doctor and for most of his adult life divided his time between medicine and writing. Best known for plays including The Cherry Orchard and Three Sisters, he is also celebrated today as one of the greatest of short story writers. His works are often powerful character studies and chronicle the changing nature of Russian society in the late nineteenth century. With: Catriona Kelly Professor o...

In a programme first broadcast in 2013, Melvyn Bragg and his guests discuss absolute zero, the lowest conceivable temperature. In the early eighteenth century the French physicist Guillaume Amontons suggested that temperature had a lower limit. The subject of low temperature became a fertile field of research in the nineteenth century, and today we know that this limit - known as absolute zero - is approximately minus 273 degrees Celsius. It is impossible to produce a temperature exactly equal t...

Melvyn Bragg and his guests discuss the life and work of the Victorian anthropologist and archaeologist Augustus Pitt-Rivers. Over many years he amassed thousands of ethnographic and archaeological objects, some of which formed the founding collection of the Pitt Rivers Museum at Oxford University. Inspired by the work of Charles Darwin, Pitt-Rivers believed that human technology evolved in the same way as living organisms, and devoted much of his life to exploring this theory. He was also a pio...

David Bradshaw, John Bowen and Ann Pasternak Slater join Melvyn Bragg to discuss Evelyn Waugh's comic novel Decline and Fall. Set partly in a substandard boys' public school, the novel is a vivid, often riotous portrait of 1920s Britain. Its themes, including modernity, religion and fashionable society, came to dominate Waugh's later fiction, but its savage wit and economy of style were entirely new. Published when Waugh was 24, the book was immediately celebrated for its vicious satire and biti...

Jane Francis, Richard Corfield and Carrie Lear join Melvyn Bragg to discuss ice ages, periods when a reduction in the surface temperature of the Earth has resulted in ice sheets at the Poles. Although the term 'ice age' is commonly associated with prehistoric eras when much of northern Europe was covered in ice, we are in fact currently in an ice age which began up to 40 million years ago. Geological evidence indicates that there have been several in the Earth's history, although their precise c...

Angie Hobbs, David Sedley and James Warren join Melvyn Bragg to discuss Epicureanism, the system of philosophy based on the teachings of Epicurus and founded in Athens in the fourth century BC. Epicurus outlined a comprehensive philosophical system based on the idea that everything in the Universe is constructed from two phenomena: atoms and void. At the centre of his philosophy is the idea that the goal of human life is pleasure, by which he meant not luxury but the avoidance of pain. His follo...

Melvyn Bragg and his guests discuss the War of 1812, the conflict between America and the British Empire sometimes referred to as the second American War of Independence. In June 1812, President James Madison declared war on Britain, angered by the restrictions Britain had imposed on American trade, the Royal Navy's capture of American sailors and British support for Native Americans. After three years of largely inconclusive fighting, the conflict finally came to an end with the Treaty of Ghent...

Melvyn Bragg and his guests discuss Romulus and Remus, the central figures of the foundation myth of Rome. According to tradition, the twins were abandoned by their parents as babies, but were saved by a she-wolf who found and nursed them. Romulus killed his brother after a vicious quarrel, and went on to found a city, which was named after him. The myth has been at the core of Roman identity since the 1st century AD, although the details vary in different versions of the story. For many Roman w...

Melvyn Bragg and his guests discuss comets, the 'dirty snowballs' of the Solar System. In the early 18th century the Astronomer Royal Sir Edmond Halley compiled a list of appearances of comets, bright objects like stars with long tails which are occasionally visible in the night sky. He concluded that many of these apparitions were in fact the same comet, which returns to our skies around every 75 years, and whose reappearance he correctly predicted. Halley's Comet is today the best known exampl...

Melvyn Bragg and his guests discuss Thomas Malory's "Le Morte Darthur", the epic tale of King Arthur and his knights of the Round Table. Sir Thomas Malory was a knight from Warwickshire, a respectable country gentleman and MP in the 1440s who later turned to a life of crime and spent various spells in prison. It was during Malory's final incarceration that he wrote "Le Morte Darthur", an epic work which was based primarily on French, but also some English, sources. Malory died shortly after his ...

Melvyn Bragg and his guests discuss the cult of Mithras, a mystery religion that existed in the Roman Empire from the 1st to the 4th centuries AD. Also known as the Mysteries of Mithras, its origins are uncertain. Academics have suggested a link with the ancient Vedic god Mitra and the Iranian Zoroastrian deity Mithra, but the extent and nature of the connection is a matter of controversy. Followers of Mithras are thought to have taken part in various rituals, most notably communal meals and a c...

Melvyn Bragg and his guests discuss The South Sea Bubble, the speculation mania in early 18th-century England which ended in the financial ruin of many of its investors. The South Sea Company was founded in 1711 with a view to restructuring government debt and restoring public credit. The company would ostensibly trade with South America, hence its name; and indeed, it did trade in slaves for the Spanish market even after the Bubble burst in 1720. People from all walks of life bought shares in t...

Melvyn Bragg and his guests discuss the epic poem the Shahnameh of Ferdowsi, the 'Book of Kings', which has been at the heart of Persian culture for the past thousand years. The poem recounts a legendary history of Iran from the dawn of time to the fall of the Persian Empire in the 7th century and serves, in a sense, as a creation myth for the Persian nation. The Shahnameh took Ferdowsi thirty years to write and, consisting of over 50,000 verses, is said to be the longest poem ever written by a ...

Melvyn Bragg and his guests discuss the French philosopher and social activist Simone Weil. Born in Paris in 1909 into a wealthy, agnostic Jewish family, Weil was a precocious child and attended the prestigious Ecole Normale Superieure in Paris, achieving the top marks in her class (Simone de Beauvoir came second). Weil rejected her comfortable background and chose to work in fields and factories to experience the life of the working classes at first hand. She was acutely sensitive to human suff...

Melvyn Bragg and his guests discuss the Upanishads, the ancient sacred texts of Hinduism. Dating from about 700 BC, the Upanishads were passed down through an oral tradition in priestly castes and were not written down until the 6th century AD. They constitute the final part of the Vedas, the collection of texts which form the foundation of the Indian Hindu world, and were originally spoken during sacrificial rituals. Yet the Upanishads go beyond incantations performed during sacrifices, and ask...

Melvyn Bragg and his guests discuss The Anarchy, the civil war that took place in mid-twelfth century England. The war began as a succession dispute between the Empress Matilda, daughter of Henry I, and her cousin, Stephen of Blois. On Henry's death Stephen seized the English throne and held it for a number of years before Matilda wrestled it from him, although she was chased out of London before she could be crowned. The Anarchy dragged on for nearly twenty years and is so called because of the...

Melvyn Bragg and his guests discuss Fermat's Last Theorem. In 1637 the French mathematician Pierre de Fermat scribbled a note in the margin of one of his books. He claimed to have proved a remarkable property of numbers, but gave no clue as to how he'd gone about it. "I have found a wonderful demonstration of this proposition," he wrote, "which this margin is too narrow to contain". Fermat's theorem became one of the most iconic problems in mathematics and for centuries mathematicians struggled ...

Melvyn Bragg and his guests discuss the life and influence of William Caxton, the merchant who brought the printing press to the British Isles. After spending several years working as a printer in Bruges, Caxton returned to London and in 1476 set up his first printing press in Westminster, and also imported and sold other printed books. Caxton concentrated on producing popular books that he knew would sell, such as Chaucer's 'Canterbury Tales' and small liturgical 'books of hours'. The standard ...

Melvyn Bragg and his guests discuss the Ontological Argument. In the eleventh century St Anselm of Canterbury proposed that it was possible to prove the existence of God using reason alone. His argument was ridiculed by some of his contemporaries, but was analysed and improved by later thinkers including Descartes, Spinoza and Leibniz. Other philosophers have been less kind, with the Enlightenment thinker David Hume offering one possible refutation. But the debate continued, fuelled by intervent...

Melvyn Bragg and his guests discuss the Druids, the priests of ancient Europe. Active in Ireland, Britain and Gaul, the Druids were first written about by Roman authors including Julius Caesar and Pliny, who described them as wearing white robes and cutting mistletoe with golden sickles. They were suspected of leading resistance to the Romans, a fact which eventually led to their eradication from ancient Britain. In the early modern era, however, interest in the Druids revived, and later writers...

Melvyn Bragg and his guests discuss the cell, the fundamental building block of life. First observed by Robert Hooke in 1665, cells occur in nature in a bewildering variety of forms. Every organism alive today consists of one or more cells: a single human body contains up to a hundred trillion of them. The first life on Earth was a single-celled organism which is thought to have appeared around three and a half billion years ago. That simple cell resembled today's bacteria. But eventually these ...

Melvyn Bragg and his guests discuss Scepticism, the idea that it may be impossible to know anything with complete certainty. Scepticism was first outlined by ancient Greek philosophers: Socrates is reported to have said that the only thing he knew for certain was that he knew nothing. Later, Scepticism was taught at the Academy founded by Plato, and learnt by students who included the Roman statesman Cicero. The central ideas of Scepticism were taken up by later philosophers and came to the fore...
