In Our Time With Melvyn Bragg Folgen

Melvyn Bragg and his guests discuss the nervous system.Most animals have a nervous system, a network of nerve tissues which allows parts of the body to communicate with each other. In humans the most significant parts of this network are the brain, spinal column and retinas, which together make up the central nervous system. But there is also a peripheral nervous system, which enables sensation, movement and the regulation of the major organs.Scholars first described the nerves of the human body over two thousand years ago. For 1400 years it was believed that they were animated by 'animal spirits', mysterious powers which caused sensation and movement. In the eighteenth century scientists discovered that nerve fibres transmitted electrical impulses; it was not until the twentieth century that chemical agents - neurotransmitters - were first identified.With:Colin Blakemore Professor of Neuroscience at the University of OxfordVivian Nutton Emeritus Professor of the History of Medicine at University College, LondonTilli Tansey Professor of the History of Modern Medical Sciences at Queen Mary, University of London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Battle of Bannockburn.On June 23rd 1314, Scottish forces under their king Robert the Bruce confronted a larger army commanded by the English monarch Edward II at Bannockburn. It was the culmination of a war of independence which had been going on since the English had invaded Scotland in 1296. After eighteen years of intermittent fighting the English had been all but expelled from Scotland: their last stronghold was the castle at Stirling.The Scots won a decisive victory at Bannockburn. The English were routed and their king narrowly escaped capture. Although it took a further 14 years for Scotland to achieve full independence with the 1328 Treaty of Edinburgh-Northampton, this was an important triumph; today it remains one of the most discussed moments in the nation's history.With:Matthew StricklandProfessor of Medieval History at the University of GlasgowFiona WatsonHonorary Research Fellow in History at the University of DundeeMichael BrownReader in History at the University of St Andrews Producer: Thomas Morris.

Melvyn Bragg and his guests discuss Aristotle's Poetics. The Poetics is, as far as we know, the first ever work of literary theory. Written in the 4th century BC, it is the work of a scholar who was also a biologist, and treats literary works with the detached analytical eye of a scientist. Aristotle examines drama and epic poetry, and how they achieve their effects; he analyses tragedy and the ways in which it plays on our emotions. Many of the ideas he articulates, such as catharsis, have remained in our critical vocabulary ever since. The book also contains an impassioned defence of poetry, which had been attacked by other thinkers, including Aristotle's own teacher Plato.Translated by medieval Arab scholars, the Poetics was rediscovered in Europe during the Renaissance and became a playwriting manual for many dramatists of the era. Today it remains a standard text for would-be Hollywood screenwriters.With:Angie HobbsAssociate Professor of Philosophy and Senior Fellow in the Public Understanding of Philosophy at the University of WarwickNick LoweReader in Classical Literature at Royal Holloway, University of LondonStephen HalliwellProfessor of Greek at the University of St AndrewsProducer: Thomas Morris.
