Melvyn Bragg and guests discuss Laplace (1749-1827) who was a giant in the world of mathematics both before and after the French Revolution. He addressed one of the great questions of his age, raised but side-stepped by Newton: was the Solar System stable, or would the planets crash into the Sun, as it appeared Jupiter might, or even spin away like Saturn threatened to do? He advanced ideas on probability, long the preserve of card players, and expanded them out across science; he hypothesised why the planets rotate in the same direction; and he asked if the Universe was deterministic, so that if you knew everything about all the particles then you could predict the future. He also devised the metric system and reputedly came up with the name 'metre'.

Melvyn Bragg and guests discuss the conflict between Russia and Japan from February 1904 to September 1905, which gripped the world and had a profound impact on both countries. Wary of Russian domination of Korea, Japan attacked the Russian Fleet at Port Arthur and the ensuing war gave Russia a series of shocks, including the loss of their Baltic Fleet after a seven month voyage, which reverberated in the 1905 Revolution. Meanwhile Japan, victorious, advanced its goal of making Europe and America more wary in East Asia, combining rapid military modernisation and Samurai traditions when training its new peasant conscripts. The US-brokered peace failed to require Russia to make reparations, which became a cause of Japanese resentment towards the US.WithSimon Dixon The Sir Bernard Pares Professor of Russian History at University College LondonNaoko Shimazu Professor of Humanities at Yale NUS College, SingaporeAndOleg Benesch Reader in Modern History at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the man who, according to Machiavelli, was the last of the Five Good Emperors. Marcus Aurelius, 121 to 180 AD, has long been known as a model of the philosopher king, a Stoic who, while on military campaigns, compiled ideas on how best to live his life, and how best to rule. These ideas became known as his Meditations, and they have been treasured by many as an insight into the mind of a Roman emperor, and an example of how to avoid the corruption of power in turbulent times.The image above shows part of a bronze equestrian statue of Marcus Aurelius.With Simon Goldhill Professor of Greek Literature and Culture and Fellow of King’s College, CambridgeAngie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldAndCatharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the plague that broke out in Constantinople 541AD, in the reign of Emperor Justinian. According to the historian Procopius, writing in Byzantium at the time, this was a plague by which the whole human race came near to being destroyed, embracing the whole world, and blighting the lives of all mankind. The bacterium behind the Black Death has since been found on human remains from that time, and the symptoms described were the same, and evidence of this plague has since been traced around the Mediterranean and from Syria to Britain and Ireland. The question of how devastating it truly was, though, is yet to be resolved.With John Haldon Professor of Byzantine History and Hellenic Studies Emeritus at Princeton UniversityRebecca Flemming Senior Lecturer in Classics at the University of CambridgeAndGreg Woolf Director of the Institute of Classical Studies, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss Chairman Mao and the revolt he led within his own party from 1966, setting communists against each other, to renew the revolution that he feared had become too bourgeois and to remove his enemies and rivals. Universities closed and the students formed Red Guard factions to attack the 'four olds' - old ideas, culture, habits and customs - and they also turned on each other, with mass violence on the streets and hundreds of thousands of deaths. Over a billion copies of Chairman Mao’s Little Red Book were printed to support his cult of personality, before Mao himself died in 1976 and the revolution came to an end.The image above is of Red Guards, holding The Little Red Book, cheering Mao during a meeting to celebrate the Great Proletarian Cultural Revolution at Tiananmen Square, Beijing, August 1966 WithRana Mitter Professor of the History and Politics of Modern China and Fellow of St Cross College, University of OxfordSun Peidong Visiting Professor at the Center for International Studies at Sciences Po, ParisAndJulia Lovell Professor in Modern Chinese History and Literature at Birkbeck, University of LondonProduced by Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss the notorious events off Jamaica in 1781 and their background. The British slave ship Zong, having sailed across the Atlantic towards Jamaica, threw 132 enslaved Africans from its human cargo into the sea to drown. Even for a slave ship, the Zong was overcrowded; those murdered were worth more to the ship dead than alive. The crew said there was not enough drinking water to go round and they had no choice, which meant they could claim for the deaths on insurance. The main reason we know of this atrocity now is that the owners took their claim to court in London, and the insurers were at first told to pay up as if the dead slaves were any other lost goods, not people. Abolitionists in Britain were scandalised: if courts treated mass murder in the slave trade as just another business transaction and not a moral wrong, the souls of the nation would be damned. But nobody was ever prosecuted.The image above is of sailors throwing slaves overboard, from Torrey's 'American Slave Trade', 1822WithVincent Brown Charles Warren Professor of American History and Professor of African and African American Studies at Harvard UniversityBronwen Everill Class of 1973 Lecturer in History and Fellow at Gonville & Caius College, University of CambridgeAnd Jake Subryan Richards Assistant Professor of History at the London School of EconomicsStudio production: Hannah Sander Producer: Simon Tillotson

Melvyn Bragg and guests discuss Maria Theresa (1717-1780) who inherited the Austrian throne in 1740 at the age of 23. Her neighbours circled like wolves and, within two months, Frederick the Great had seized one of her most prized lands, Silesia, exploiting her vulnerability. Yet over the next forty years through political reforms, alliances and marriages, she built Austria up into a formidable power, and she would do whatever it took to save the souls of her Catholic subjects, with a rigidity and intolerance that Joseph II, her son and heir, could not wait to challenge.

Melvyn Bragg and guests discuss ideas about the Stone Age people who created the extraordinary images found in caves around the world, from hand outlines to abstract symbols to the multicoloured paintings of prey animals at Chauvet and, as shown above, at Lascaux. In the 19th Century, it was assumed that only humans could have made these, as Neanderthals would have lacked the skills or imagination, but new tests suggest otherwise. How were the images created, were they meant to be for private viewing or public spaces, and what might their purposes have been? And, if Neanderthals were capable of creative work, in what ways were they different from humans? What might it have been like to experience the paintings, so far from natural light?

Melvyn Bragg and guests discuss Pericles (495-429BC), the statesman who dominated the politics of Athens for thirty years, the so-called Age of Pericles, when the city’s cultural life flowered, its democracy strengthened as its empire grew, and the Acropolis was adorned with the Parthenon. In 431 BC he gave a funeral oration for those Athenians who had already died in the new war with Sparta which has been celebrated as one of the greatest speeches of all time, yet within two years he was dead from a plague made worse by Athenians crowding into their city to avoid attacks. Thucydides, the historian, knew him and was in awe of him, yet few shared that view until the nineteenth century, when they found much in Pericles to praise, an example for the Victorian age.

Melvyn Bragg and guests discuss the bonds that Scottish Presbyterians made between themselves and their monarchs in the 16th and 17th Centuries, to maintain their form of worship. These covenants bound James VI of Scotland to support Presbyterians yet when he became James I he was also expected to support episcopacy. That tension came to a head under Charles I who found himself on the losing side of a war with the Covenanters, who later supported Parliament before backing the future Charles II after he had pledged to support them. Once in power, Charles II failed to deliver the religious settlement the Covenanters wanted, and set about repressing them violently. Those who refused to renounce the covenants were persecuted in what became known as The Killing Times, as reflected in the image above.With Roger Mason Professor of Scottish History at the University of St AndrewsLaura Stewart Professor of Early Modern British History at the University of YorkAndScott Spurlock Professor of Scottish and Early Modern Christianities at the University of GlasgowProducer: Simon Tillotson
