Melvyn Bragg and guests discuss the speed of light. Scientists and thinkers have been fascinated with the speed of light for millennia. Aristotle wrongly contended that the speed of light was infinite, but it was the 17th Century before serious attempts were made to measure its actual velocity – we now know that it’s 186,000 miles per second. Then in 1905 Einstein’s Special Theory of Relativity predicted that nothing can travel faster than the speed of light. This then has dramatic effects on th...

Melvyn Bragg and guests discuss altruism. The term altruism was coined by the 19th century sociologist Auguste Comte and is derived from the Latin “alteri” or "the others”. It describes an unselfish attention to the needs of others. Comte declared that man had a moral duty to “serve humanity, whose we are entirely.” The idea of altruism is central to the main religions: Jesus declared “you shall love your neighbour as yourself” and Mohammed said “none of you truly believes until he wishes for hi...

Melvyn Bragg and guests discuss the Peasants’ Revolt of 1381. “When Adam delved and Eve span, who was then the Gentleman?" these are the opening words of a rousing sermon, said to be by John Ball, which fires a broadside at the deeply hierarchical nature of fourteenth century England. Ball, along with Wat Tyler, was one of the principal leaders of the Peasants’ Revolt – his sermon ends: "I exhort you to consider that now the time is come, appointed to us by God, in which ye may (if ye will) cast...

Melvyn Bragg and guests discuss the life and work of Alexander Pope. His enemies – who were numerous - described him as a hunchbacked toad, twisted in body, twisted in mind, but Alexander Pope is without doubt one of the greatest poets of the English language. His acerbic wit and biting satire were the scourge of politicians, fellow writers and most especially the critics. He was the first Englishman to make a living from his pen, free from the shackles of patronage and flattery. Indeed, his sha...

Melvyn Bragg and guests discuss the Poincaré Conjecture. The great French mathematician Henri Poincaré declared: “The scientist does not study mathematics because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing and life would not be worth living. And it is because simplicity, because grandeur, is beautiful that we preferably seek simple facts, sublime facts, and that we delight now t...

Melvyn Bragg and guests discuss the French encyclopédie, the European Enlightenment in book form. One of its editors, D’Alembert, described its mission as giving an overview of knowledge, as if gazing down on a vast labyrinth of all the branches of human ideas, observing where they separate or unite and even catching sight of the secret routes between them. It was a project that attracted some of the greatest thinkers of the Enlightenment - Voltaire, Rousseau and Diderot - striving to bring toge...

Melvyn Bragg and guests discuss the Needham Question; why Europe and not China developed modern technology. What do these things have in common? Fireworks, wood-block printing, canal lock-gates, kites, the wheelbarrow, chain suspension bridges and the magnetic compass. The answer is that they were all invented in China, a country that, right through the Middle Ages, maintained a cultural and technological sophistication that made foreign dignitaries flock to its imperial courts for trade and fav...

Melvyn Bragg and guests discuss the Diet of Worms, an event that helped trigger the European Reformation. Nestled on a bend of the River Rhine, in the South West corner of Germany, is the City of Worms. It’s one of the oldest cities in central Europe; it still has its early city walls, its 11th century Romanesque cathedral and a 500-year-old printing industry, but in its centre is a statue of the monk, heretic and founder of the Protestant Reformation, Martin Luther. In 1521 Luther came to Worms...

Melvyn Bragg and guests discuss the philosopher Averroes who worked to reconcile the theology of Islam with the rationality of Aristotle achieving fame and infamy in equal measure In The Divine Comedy Dante subjected all the sinners in Christendom to a series of grisly punishments, from being buried alive to being frozen in ice. The deeper you go the more brutal and bizarre the punishments get, but the uppermost level of Hell is populated not with the mildest of Christian sinners, but with non-C...

Melvyn Bragg and guests discuss the Prussian naturalist and explorer Alexander Von Humboldt. He was possibly the greatest and certainly one of the most famous scientists of the 19th century. Darwin described him as 'the greatest scientific traveller who ever lived'. Goethe declared that one learned more from an hour in his company than eight days of studying books and even Napoleon was reputed to be envious of his celebrity.A friend of Goethe and an influence on Coleridge and Shelly, when Darwin...

Melvyn Bragg and guests discuss comedy in Ancient Greek theatre including Aristophanes and Menander. In The Birds, written by Aristophanes, two Athenians seek a Utopian refuge from the madness of city life and found a city of birds located between Earth and Olympus. Unfortunately, the idealism of their perfect new City - christened (in 414 BC) 'Cloud Cuckoo Land' - becomes corrupted and its decline was portrayed by one man (the chorus) playing 24 different species of bird. In one of Aristophanes...

Melvyn Bragg and guests discuss the galaxies. Spread out across the voids of space like spun sugar, but harbouring in their centres super-massive black holes. Our galaxy is about 100,000 light years across, is shaped like a fried egg and we travel inside it at approximately 220 kilometres per second. The nearest one to us is much smaller and is nicknamed the Sagittarius Dwarf. But the one down the road, called Andromeda, is just as large as ours and, in 10 billion years, we'll probably crash int...

Melvyn Bragg and guests discuss the Spanish Inquisition, the defenders of medieval orthodoxy. The word ‘Inquisition’ has its roots in the Latin word 'inquisito' which means inquiry. The Romans used the inquisitorial process as a form of legal procedure employed in the search for evidence. Once Rome's religion changed to Christianity under Constantine, it retained the inquisitorial trial method but also developed brutal means of dealing with heretics who went against the doctrines of the new reli...

Melvyn Bragg and guests discuss Carbon. It forms the basis of all organic life and has the amazing ability to bond with itself and a wide range of other elements, forming nearly 10 million known compounds. It is in the food we eat, the clothes we wear, the shampoo we use and the petrol that fuels our cars. Because carbon has the largest range of subtle bonding capabilities, 95% of everything that exists in the universe is made up of carbon atoms that are stuck together. It is an extraordinary el...

Melvyn Bragg and guests discuss the anti slavery novel, 'Uncle Tom's Cabin'. When Abraham Lincoln met the writer Harriet Beecher Stowe after the start of the American Civil War, he reportedly said to her: 'So you're the little lady whose book started this big war'. Stowe's novel Uncle Tom's Cabin, published in 1852, is credited as fuelling the cause to abolish slavery in the northern half of the United States in direct response to its continuation in the South. The book deals with the harsh real...

Melvyn Bragg and guests discuss the heart. Aristotle considered the heart to be the seat of thought, reason and emotion. The Roman physician Galen located the seat of the passions in the liver, the seat of reason in the brain, and considered the heart to be the seat of the emotions. It was not until the 17th century that the physician William Harvey wrote in the preface to his thesis On the Motion of the Heart and Blood in Animals, a letter addressed to King Charles I. 'The heart of animals is t...

Melvyn Bragg and guests discuss the mathematical structures that lie within the heart of music. The seventeenth century philosopher Gottfried Leibniz wrote: 'Music is the pleasure the human mind experiences from counting without being aware that it is counting'. Mathematical structures have always provided the bare bones around which musicians compose music and have been vital to the very practical considerations of performance such as fingering and tempo. But there is a more complex area in the...

Melvyn Bragg and guests discuss the great nineteenth century political philosopher John Stuart Mill. He believed that, 'The true philosophy is the marriage of poetry and logic'. He was one of the first thinkers to argue that a social theory must engage with ideas of culture and the internal life. He used Wordsworth to inform his social theory, he was a proto feminist and his treatise On Liberty is one of the sacred texts of liberalism. J S Mill believed that action was the natural articulation o...

Melvyn Bragg and guests discuss the literary and visual depiction of fairies, supernatural creatures that inhabit a half-way world between this one and the next.'They stole little Bridget for seven years long; When she came down again her friends were all gone. They took her lightly back, between the night and morrow; They thought that she was fast asleep, but she was dead with sorrow. They have kept her ever since deep within the lake, On a bed of flag-leaves, watching till she wake.' When the ...

Melvyn Bragg and guests discuss the relationship between astronomy and the British Empire. The 18th century explorer and astronomer James Cook wrote: 'Ambition leads me not only farther than any other man has been before me, but as far as I think it possible for man to go'. Cook's ambition took him to the far reaches of the Pacific and led to astronomical observations which measured the distance of Venus to the Sun with unprecedented accuracy. Cook's ambition was not just personal and astronomic...

Melvyn Bragg and guests discuss the 1851 Great Exhibition. “Its grandeur does not consist in one thing, but in the unique assemblage of all things. Whatever human industry has created you find there. It seems as if only magic could have gathered this mass of wealth from all the ends of the earth.” So wrote Charlotte Bronte in 1851 after visiting the Great Exhibition set in the vast Crystal Palace in London's Hyde Park. By the time the exhibition closed, one quarter of the entire British populati...

Melvyn Bragg and guests discuss the search for immunisation. In 1717, Lady Mary Wortley Montagu, the wife of the British Ambassador to the Ottoman Empire, wrote a letter to her friend describing how she had witnessed the practice of smallpox inoculation in Constantinople. This involved the transfer of material from a smallpox postule into multiple cuts made in a vein. Lady Montagu had lost her brother to smallpox and was amazed that the Middle Eastern practice of inoculation rendered the fatal d...

Melvyn Bragg and guests discuss the Oxford Movement in the Church of England in the 19th century. Cardinal John Henry Newman is perhaps the most significant Christian theologian of the nineteenth century. He began as an evangelical, becoming a High Anglican before converting to Roman Catholicism in 1845. His is the story of the diversity of Victorian religious life. But his path also marks the waning of the ideas of Protestant nationhood at the close of the eighteenth century and the reaffirmati...

Melvyn Bragg and guests discuss the Holy Roman Emperor Charlemagne and the Carolingian Renaissance. In 800 AD on Christmas Day in Rome, Pope Leo III proclaimed Charlemagne Emperor. According to the Frankish historian Einhard, Charlemagne would never have set foot in St Peter's that day if he had known that the Pope intended to crown him. But Charlemagne accepted his coronation with magnanimity. Regarded as the first of the Holy Roman Emperors, Charlemagne became a touchstone for legitimacy until...

Melvyn Bragg and guests discuss the formation of the Royal Society. In the 17th century the natural philosopher Francis Bacon heralded the new age of science. The frontispiece to his 1620 edition of the Instauratio Magna depicted a galleon travelling between the metaphorical Pillars of Hercules thought to lie at the Strait of Gibraltar and believed to mark the end of the known world. The image encapsulated Bacon's desire to sail beyond the limits set by Aristotle and the curriculum of the Ancien...

Melvyn Bragg and guests discuss negative numbers, a history of mystery and suspicion. In 1759 the British mathematician Francis Maseres wrote that negative numbers "darken the very whole doctrines of the equations and make dark of the things which are in their nature excessively obvious and simple". Because of their dark and mysterious nature, Maseres concluded that negative numbers did not exist, as did his contemporary, William Friend. However, other mathematicians were braver. They took a lea...

Melvyn Bragg and guests discuss the concept of friendship. In Greek and Roman times, friendship was thought of as being an essential constituent of both a good society and a good life; a good society because it lay at the heart of participative civic democracy; a good life because it nurtured wisdom and happiness. It is this period which gives us the texts on friendship which, to this day, are arguably the most important of their kind. Amongst their authors is Aristotle, who engaged in one of th...
