Spanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious. In each episode, host Misha Glenny and expert guests explore the characters, events and discoveries that have shaped our world. History fans can learn about pivotal wars and societal upheavals, such as the rise and fall of Napoleon, the Sack of Rome in 1527, and the political intrigue of the Russian Revolution. Those fascinated by the lives of kings and queens can journey to Versailles to meet Marie Antoinette and Louis XIV the Sun King, or to Ancient Egypt to meet Cleopatra and Nefertiti. Or perhaps you're looking to explore the history of religion, from Buddhism's early teachings to the Protestant Reformation. If you're interested in the stories behind iconic works of art, music and literature, dive in to discussions on the artistic genius of Michelangelo's Sistine Chapel and Van Gogh's famous Sunflowers. From Gothic architecture to the works of Shakespeare, each episode of In Our Time offers new insight into humanity's cultural achievements. Those looking to enrich their scientific knowledge can hear episodes on black holes, the Periodic Table, and classical theories of gravity, motion, evolution and relativity. Learn how the discovery of penicillin revolutionised medicine, and how the death of stars can lead to the formation of new planets. Lovers of philosophy will find episodes on the big issues that define existence, from free will and ethics, to liberty and justice. In what ways did celebrated philosophers such as Mary Wollstonecraft and Karl Marx push forward radical new ideas? How has the concept of karma evolved from the ancient Sanskrit texts of Hinduism to today? What was Plato's concept of an ideal republic, and how did he explore this through the legend of the lost city of Atlantis? In Our Time celebrates the pursuit of knowledge and the enduring power of ideas.

Folge vom 29.01.2004CryptographyMelvyn Bragg and guests discuss the origins and history of codes. In October 1586, in the forbidding hall of Fotheringhay Castle, Mary Queen of Scots was on trial for her life. Accused of treason and denied legal representation, she sat alone in the shadow of a vast and empty throne belonging to her absent cousin and arch rival Elizabeth I of England. Walsingham, Elizabeth’s Principal Secretary, had already arrested and executed Mary’s fellow conspirators, her only hope lay in the code she had used in all her letters concerning the plot. If her cipher remained unbroken she might yet be saved. Not for the first time the life of an individual and the course of history depended on the arcane art of Cryptography.What are the origins of this secretive science? And what links the ‘Caesar Cipher’ with the complex algorithms which underpin so much of our modern age?With Simon Singh, science writer and author of The Code Book: The Secret History of Codes and Code-Breaking; Professor Fred Piper, Director of the Information Security Group at Royal Holloway, University of London and co-author of Cryptography: A Very Short Introduction; Lisa Jardine, Professor of Renaissance Studies at Queen Mary, University of London and author of Ingenious Pursuits.

Folge vom 24.12.2003Lamarck and Natural SelectionMelvyn Bragg discusses Jean-Baptiste Lamarck, the 18th century French scientist.Charles Darwin defined Natural Selection in On the Origin of Species, Variations, however slight and from whatever cause proceeding, if they be in any degree profitable to the individuals of a species will tend to the preservation of such individuals, and will generally be inherited by the offspring. It was a simple idea that had instant recognition, How extremely stupid not to have thought of that! said T H Huxley. However, Darwin did not invent the idea of evolution and not everyone saw his ideas as original. The great geologist Charles Lyell repeatedly referred to Lamarcks theory as modified by Darwin, Darwin complained to him, I believe this way of putting the case is very injurious to its acceptance. He desperately wanted to escape the shadow of this genuine scientific precursor and what has become known as the Lamarckian Heresy has maintained a ghostly presence on the fringes of biology to this day.Who was Lamarck? How did Natural Selection escape from his shadow and gain acceptance from the scientific establishment? And has any evidence emerged that might challenge the elegant simplicity of Darwins big idea?With Sandy Knapp, Senior Botanist at the Natural History Museum, Steve Jones, Professor of Genetics in the Galton Laboratory at University College London and author of Almost Like a Whale: The Origin of Species Updated; Simon Conway Morris, Professor of Evolutionary Paleobiology at Cambridge University.

Folge vom 18.12.2003The AlphabetMelvyn Bragg and guests discuss the feat of astonishing intellectual engineering which provides us with millions of words in hundreds of languages. At the start of the twentieth century, in the depths of an ancient Egyptian turquoise mine on the Sinai peninsular, an archaeologist called Sir Flinders Petrie made an exciting discovery. Scratched onto rocks, pots and portable items, he found scribblings of a very unexpected but strangely familiar nature. He had expected to see the complex pictorial hieroglyphic script the Egyptian establishment had used for over 1000 years, but it seemed that at this very early period, 1700 BC, the mine workers and Semitic slaves had started using a new informal system of graffiti, one which was brilliantly simple, endlessly adaptable and perfectly portable: the Alphabet. This was probably the earliest example of an alphabetic script and it bears an uncanny resemblance to our own.Did the alphabet really spring into life almost fully formed? How did it manage to conquer three quarters of the globe? And despite its Cyrillic and Arabic variations and the myriad languages it has been used to write, why is there essentially only one alphabet anywhere in the world? With Eleanor Robson, historian of Ancient Iraq and Fellow of All Souls College, Oxford; Alan Millard, Rankin Professor Emeritus of Hebrew and Ancient Semitic Languages at the University of Liverpool; Rosalind Thomas, Professor of Greek History at Royal Holloway, University of London.

Folge vom 11.12.2003The DevilMelvyn Bragg and guests discuss the history of the Devil. In the Gospel according to John he is ‘a murderer from the beginning’, ‘a liar and the father of lies’, and Dante calls him ‘the ill Worm that pierces the world’s core’. But Milton’s description of him as a powerful rebel was so attractive that William Blake declared that Milton was ‘of the Devil’s party, without knowing it’. To ordinary folk the Devil has often been regarded as a trickster, a tempter, sometimes even a figure of fun rather than of fear. How did this contradictory character come into being? Why did it take so long for him to become an established figure in Christianity? And if the Devil did not exist, would we have had to invent him? With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Alison Rowlands, Senior Lecturer in European History at the University of Essex; David Wootton, Professor of Intellectual History at Queen Mary, University of London.
