The Epic of Gilgamesh (Summer Repeat)July 30, 2020
"He who saw the Deep" are the first words of the standard version of The Epic of Gilgamesh, the subject of this discussion between Melvyn Bragg and his guests which was first broadcast in 2016. Gilgamesh is often said to be the oldest surviving great work of literature, with origins in the third millennium BC, and it passed through thousands of years on cuneiform tablets. Unlike epics of Greece and Rome, the intact story of Gilgamesh became lost to later generations until tablets were discovered...

Kant's Categorical Imperative (Summer Repeat)July 23, 2020
In a programme first broadcast in 2017, Melvyn Bragg and guests discuss how, in the Enlightenment, Immanuel Kant (1724-1804) sought to define the difference between right and wrong by applying reason, looking at the intention behind actions rather than at consequences. He was inspired to find moral laws by natural philosophers such as Newton and Leibniz, who had used reason rather than emotion to analyse the world around them and had identified laws of nature. Kant argued that when someone was...

P vs NP (Summer Repeat)July 16, 2020
In a programme first broadcast in 2015, Melvyn Bragg and guests discuss the problem of P versus NP, which has a bearing on online security. There is a $1,000,000 prize on offer from the Clay Mathematical Institute for the first person to come up with a complete solution. At its heart is the question "are there problems for which the answers can be checked by computers, but not found in a reasonable time?" If the answer to that is yes, then P does not equal NP. However, if all answers can be...

1816, the Year Without a Summer (Summer Repeat)July 09, 2020
In a programme first broadcast in 2016, Melvyn Bragg and guests discuss the impact of the eruption of Mt Tambora, in 1815, on the Indonesian island of Sambawa. This was the largest volcanic eruption in recorded history and it had the highest death toll, devastating people living in the immediate area. Tambora has been linked with drastic weather changes in North America and Europe the following year, with frosts in June and heavy rains throughout the summer in many areas. This led to food...

Mary, Queen of ScotsJuly 02, 2020
In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the history of Mary, Queen of Scots, who had potential to be one of the most powerful rulers in Europe, yet she was also one of the most vulnerable. In France, when she was the teenage bride to their future king, she was seen as rightful heir to the thrones of England and Ireland, as well as Queen of Scotland and one day of France, which would have been an extraordinary union. She was widowed too young, though and, a...

Hannah ArendtJune 25, 2020
In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the political philosophy of Hannah Arendt. She developed many of her ideas in response to the rise of totalitarianism in the C20th, partly informed by her own experience as a Jew in Nazi Germany before her escape to France and then America. She wanted to understand how politics had taken such a disastrous turn and, drawing on ideas of Greek philosophers as well as her peers, what might be done to create a better political...

Bird MigrationJune 18, 2020
In a programme first broadcast in 2017, Melvyn Bragg and guests discuss why some birds migrate and others do not, how they select their destinations and how they navigate the great distances, often over oceans. For millennia, humans set their calendars to birds' annual arrivals, and speculated about what happened when they departed, perhaps moving deep under water, or turning into fish or shellfish, or hibernating while clinging to trees upside down. Ideas about migration developed in C19th...

Frederick DouglassJune 11, 2020
In a programme first broadcast in 2018, Melvyn Bragg and guests discuss the life and ideas of Frederick Douglass, who was born into slavery in Maryland in 1818 and, once he had escaped, became one of that century's most prominent abolitionists. He was such a good orator, his opponents doubted his story, but he told it in grim detail in 1845 in his book 'Narrative of the Life of Frederick Douglass, an American Slave.' He went on to address huge audiences in Great Britain and Ireland and there...

Absolute ZeroJune 04, 2020
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...

Zeno's ParadoxesMay 28, 2020
Melvyn Bragg and guests discuss Zeno of Elea, a pre-Socratic philosopher from c490-430 BC whose paradoxes were described by Bertrand Russell as "immeasurably subtle and profound." The best known argue against motion, such as that of an arrow in flight which is at a series of different points but moving at none of them, or that of Achilles who, despite being the faster runner, will never catch up with a tortoise with a head start. Aristotle and Aquinas engaged with these, as did Russell, yet it...
