The Evolution of Crocodiles

Melvyn Bragg and guests discuss the development of photography in the 1830s, when techniques for 'drawing with light' evolved to the stage where, in 1839, both Louis Daguerre and William Henry Fox Talbot made claims for its invention. These followed the development of the camera obscura, and experiments by such as Thomas Wedgwood and Nicéphore Niépce, and led to rapid changes in the 1840s as more people captured images with the daguerreotype and calotype. These new techniques changed the aesthetics of the age and, before long, inspired claims that painting was now dead.WithSimon Schaffer Professor of the History of Science at the University of CambridgeElizabeth Edwards Emeritus Professor of Photographic History at De Montfort UniversityAndAlison Morrison-Low, Research Associate at National Museums ScotlandProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the history of the idea of Sovereignty, the authority of a state to govern itself and the relationship between the sovereign and the people. These ideas of external and internal sovereignty were imagined in various ways in ancient Greece and Rome, and given a name in 16th Century France by the philosopher and jurist Jean Bodin in his Six Books of the Commonwealth, where he said (in an early English translation) 'Maiestie or Soveraigntie is the most high, absolute, and perpetuall power over the citisens and subiects in a Commonweale: which the Latins cal Maiestatem, the Greeks akra exousia, kurion arche, and kurion politeuma; the Italians Segnoria, and the Hebrewes tomech shévet, that is to say, The greatest power to command.' Shakespeare also explored the concept through Richard II and the king's two bodies, Hobbes developed it in the 17th Century, and the idea of popular sovereignty was tested in the Revolutionary era in America and France.

Melvyn Bragg and guests discuss William Blake's collection of illustrated poems "Songs of Innocence and of Experience." He published Songs of Innocence first in 1789 with five hand-coloured copies and, five years later, with additional Songs of Experience poems and the explanatory phrase "Shewing the Two Contrary States of the Human Soul." Blake drew on the street ballads and improving children's rhymes of the time, exploring the open and optimistic outlook of early childhood with the darker and more cynical outlook of adult life, in which symbols such as the Lamb belong to innocence and the Tyger to experience.WithSir Jonathan Bate Provost of Worcester College, University of OxfordSarah Haggarty Lecturer at the Faculty of English and Fellow of Queens' College, University of CambridgeAndJon Mee Professor of Eighteenth-Century Studies at the University of YorkProducer: Simon Tillotson.

Melvyn Bragg and guests discuss The Bronze Age Collapse, the name given by many historians to what appears to have been a sudden, uncontrolled destruction of dominant civilizations around 1200 BC in the Aegean, Eastern Mediterranean and Anatolia. Among other areas, there were great changes in Minoan Crete, Egypt, the Hittite Empire, Mycenaean Greece and Syria. The reasons for the changes, and the extent of those changes, are open to debate and include droughts, rebellions, the breakdown of trade as copper became less desirable, earthquakes, invasions, volcanoes and the mysterious Sea Peoples.

Melvyn Bragg and guests discuss penicillin, discovered by Alexander Fleming in 1928. It is said he noticed some blue-green penicillium mould on an uncovered petri dish at his hospital laboratory, and that this mould had inhibited bacterial growth around it. After further work, Fleming filtered a broth of the mould and called that penicillin, hoping it would be useful as a disinfectant. Howard Florey and Ernst Chain later shared a Nobel Prize in Medicine with Fleming, for their role in developing a way of mass-producing the life-saving drug. Evolutionary theory predicted the risk of resistance from the start and, almost from the beginning of this 'golden age' of antibacterials, scientists have been looking for ways to extend the lifespan of antibiotics.WithLaura Piddock Professor of Microbiology at the University of BirminghamChristoph Tang Professor of Cellular Pathology and Professorial Fellow at Exeter College at the University of OxfordAndSteve Jones Emeritus Professor of Genetics at University College, LondonProducer: Simon Tillotson.

To celebrate Melvyn Bragg’s 27 years presenting In Our Time, five well-known fans of the programme have chosen their favourite episodes. Author and columnist Caitlin Moran has picked the episode on the English medieval mystic Margery Kempe and recorded an introduction to it. Margery Kempe (1373-1438) produced an account of her extraordinary life in a book she dictated, "The Book of Margery Kempe." She went on pilgrimage to Jerusalem, to Rome and Santiago de Compostela, purchasing indulgences on her way, met with the anchoress Julian of Norwich and is honoured by the Church of England each 9th November. She sometimes doubted the authenticity of her mystical conversations with God, as did the authorities who saw her devotional sobbing, wailing and convulsions as a sign of insanity and dissoluteness. Her Book was lost for centuries, before emerging in a private library in 1934.This In Our Time episode was first broadcast in June 2016. The image (above), of an unknown woman, comes from a pew at Margery Kempe's parish church, St Margaret’s, Kings Lynn and dates from c1375.

Melvyn Bragg and guests discuss Abraham Lincoln's Gettysburg Address, ten sentences long, delivered at the dedication of the Soldiers' National Cemetery at Gettysburg after the Union forces had won an important battle with the Confederates. Opening with " Four score and seven years ago," it became one of the most influential statements of national purpose, asserting that America was "conceived in liberty, and dedicated to the proposition that all men are created equal" and "that this nation, under God, shall have a new birth of freedom-and that government of the people, by the people, for the people, shall not perish from the earth." Among those inspired were Martin Luther King Jr whose "I have a dream" speech, delivered at the Lincoln Memorial 100 years later, echoed Lincoln's opening words.With Catherine Clinton Denman Chair of American History at the University of Texas and International Professor at Queen's University, BelfastSusan-Mary Grant Professor of American History at Newcastle UniversityAndTim Lockley Professor of American History at the University of WarwickProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Muses and their role in Greek mythology, when they were goddesses of poetry, song, music and dance: what the Greeks called mousike, 'the art of the Muses' from which we derive our word 'music.' While the number of Muses, their origin and their roles varied in different accounts and at different times, they were consistently linked with the nature of artistic inspiration. This raised a question for philosophers then and since: was a creative person an empty vessel into which the Muses poured their gifts, at their will, or could that person do something to make inspiration flow?
