In Our Time

Melvyn Bragg and his guests discuss the eye. Humans have been attempting to understand the workings and significance of the organ for at least 2500 years. Some ancient philosophers believed that the eye enabled creatures to see by emitting its own light. The function and structures of the eye became an area of particular interest to doctors in the Islamic Golden Age. In Renaissance Europe the work...

Melvyn Bragg and his guests discuss Social Darwinism. After the publication of Charles Darwin's masterpiece On the Origin of Species in 1859, some thinkers argued that Darwin's ideas about evolution could also be applied to human society. One thinker particularly associated with this movement was Darwin's near-contemporary Herbert Spencer, who coined the phrase 'survival of the fittest'. He argued...

Melvyn Bragg and his guests discuss chivalry, the moral code observed by knights of the Middle Ages. Chivalry originated in the military practices of aristocratic French and German soldiers, but developed into an elaborate system governing many different aspects of knightly behaviour. It influenced the conduct of medieval military campaigns and also had important religious and literary dimensions....

Melvyn Bragg and his guests discuss the Phoenicians. The Greek historian Herodotus wrote about a people from the Levant who were accomplished sailors and traders, and who taught the Greeks their alphabet. He called them the Phoenicians, the Greek word for purple, although it is not known what they called themselves. By about 700 BC they were trading all over the Mediterranean, taking Egyptian and...

Melvyn Bragg and his guests discuss Catastrophism, the idea that natural disasters have had a significant influence in moulding the Earth's geological features. In 1822 William Buckland, the first reader of Geology at the University of Oxford, published his famous Reliquae Diluvianae, in which he ascribed most of the fossil record to the effects of Noah's flood. Charles Lyell in his Principles of...

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 discove...

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...

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,...

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 gove...

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 appli...

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...

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 askin...

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 nake...

Melvyn Bragg and his guests discuss the life of Pocahontas, the Native American woman who to English eyes became a symbol of the New World. During the colonisation of Virginia in the first years of the seventeenth century, Pocahontas famously saved the life of an English prisoner, John Smith. Later captured, she converted to Christianity, married a settler and travelled to England where she was re...

Melvyn Bragg and his guests discuss Shakespeare's play The Tempest. Written in around 1610, it is thought to be one of the playwright's final works and contains some of the most poetic and memorable passages in all his output. It was influenced by accounts of distant lands written by contemporary explorers, and by the complex international politics of the early Jacobean age. The Tempest is set ent...

Melvyn Bragg and his guests discuss Ordinary Language Philosophy, a school of thought which emerged in Oxford in the years following World War II. With its roots in the work of Ludwig Wittgenstein, Ordinary Language Philosophy is concerned with the meanings of words as used in everyday speech. Its adherents believed that many philosophical problems were created by the misuse of words, and that if...

Melvyn Bragg and his guests discuss the Berlin Conference of 1884. In the 1880s, as colonial powers attempted to increase their spheres of influence in Africa, tensions began to grow between European nations including Britain, Belgium and France. In 1884 the German Chancellor, Otto von Bismarck, brought together many of Europe's leading statesmen to discuss trade and colonial activities in Africa....

Melvyn Bragg and his guests discuss the Corn Laws. In 1815 the British Government passed legislation which artificially inflated the price of corn. The measure was supported by landowners but strongly opposed by manufacturers and the urban working class. In the 1830s the Anti-Corn Law League was founded to campaign for their repeal, led by the Radical Richard Cobden. The Conservative government of...

Melvyn Bragg and his guests discuss the Book of Common Prayer. In 1549, at the height of the English Reformation, a new prayer book was published containing versions of the liturgy in English. Generally believed to have been supervised by Thomas Cranmer, the Book of Common Prayer was at the centre of the decade of religious turmoil that followed, and disputes over its use were one of the major cau...

Melvyn Bragg and his guests discuss the Roman physician and medical theorist Galen. The most celebrated doctor in the ancient world, Galen was Greek by birth but spent most of his career in Rome, where he was personal physician to three Emperors. He was one of the most prolific authors of his age, and a sixth of all surviving ancient literature in Greek was written by him. Celebrated in his own li...

Melvyn Bragg and his guests discuss exoplanets. Astronomers have speculated about the existence of planets beyond our solar system for centuries. Although strenuous efforts were made to find such planets orbiting distant stars, it was not until the 1990s that instruments became sophisticated enough to detect such remote objects. In 1992 Dale Frail and Aleksander Wolszczan discovered the first conf...

Melvyn Bragg and his guests discuss the Mamluks, who ruled Egypt and Syria from about 1250 to 1517. Originally slave soldiers who managed to depose their masters, they went on to repel the Mongols and the Crusaders to become the dominant force in the medieval Islamic Middle Eastern world. Although the Mamluks were renowned as warriors, under their rule art, crafts and architecture blossomed. Littl...

Melvyn Bragg and his guests begin a new series of the programme with a discussion of the French polymath Blaise Pascal. Born in 1623, Pascal was a brilliant mathematician and scientist, inventing one of the first mechanical calculators and making important discoveries about fluids and vacuums while still a young man. In his thirties he experienced a religious conversion, after which he devoted mos...

Melvyn Bragg and his guests discuss the invention of radio. In the early 1860s the Scottish physicist James Clerk Maxwell derived four equations which together describe the behaviour of electricity and magnetism. They predicted the existence of a previously unknown phenomenon: electromagnetic waves. These waves were first observed in the early 1880s, and over the next two decades a succession of s...

Melvyn Bragg and his guests discuss the Romance of the Three Kingdoms, widely regarded as one of the greatest works of Chinese literature. Written 600 years ago, it is an historical novel that tells the story of a tumultuous period in Chinese history, the 2nd and 3rd centuries AD. Partly historical and partly legend, it recounts the fighting and scheming of the feudal lords and the three states wh...
