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 23.10.2003InfinityMelvyn Bragg and guests discuss the nature and existence of mathematical infinity. Jonathan Swift encapsulated the counter-intuitive character of infinity with insouciant style:“So, naturalists observe, a fleaHath smaller fleas on him that preyAnd these hath smaller fleas to bite ‘emAnd so proceed ad infinitum.”Alas, the developing utility mathematicians put to the idea of infinity did not find the English philosopher Thomas Hobbes quite so relaxed. When confronted with a diagram depicting an infinite solid whose volume was finite, he wrote, “To understand this for sense, it is not required that a man should be a geometrician or logician, but that he should be mad”. Yet philosophers and mathematicians have continued to grapple with the unending, and it is a core concept in modern maths.So, what is mathematical infinity? Are some infinities bigger than others? And does infinity exist in nature?With Ian Stewart, Professor of Mathematics at the University of Warwick; Robert Kaplan, co-founder of The Math Circle at Harvard University and author of The Art of the Infinite: Our Lost Language of Numbers; Sarah Rees, Reader in Pure Mathematics at the University of Newcastle.

Folge vom 16.10.2003The SchismMelvyn Bragg and guests discuss events surrounding the medieval division of the Christian Church. In 1054, Cardinal Humbert stormed into the Cathedral of Constantinople and charged down the aisle. In his hand was a Papal Bull – a deed of excommunication - and he slammed it down onto the altar. As he swept out of the startled church, the Papal Legate and his entourage stopped at the door and symbolically shook the sullied dust of Eastern Christianity from their Catholic boots. The Pope of Rome had decreed that the Patriarch of Constantinople was denied his place in heaven, and soon afterwards the Patriarch excommunicated the Pope in return.It was the culmination of an argument over a single word in the Nicene Creed - but after a thousand years of being one Church, so began a permanent rift.But what were the real underlying reasons behind the split, what were its effects and why did it take until December 1965 for the excommunications to be finally revoked?With Henrietta Leyser, medieval historian and Fellow of St Peter’s College, Oxford; Norman Housley, Professor of Medieval History at the University of Leicester; Jonathan Shepard, editor of the Cambridge History of the Byzantine Empire.

Folge vom 09.10.2003BohemianismMelvyn Bragg and guests discuss the 19th century Parisian philosophy of life lived for art. In 1848 the young Parisian Henri Murger wrote of his bohemian friends: Their daily existence is a work of genius…they know how to practise abstinence with all the virtue of an anchorite, but if a slice of fortune falls into their hands you will see them at once mounted on the most ruinous fancies, loving the youngest and prettiest, drinking the oldest and best, and never finding sufficient windows to throw their money out of. Then, when their last crown is dead and buried...they go poaching on all the callings that have any connection with art, hunting from morn till night that wild beast called a five franc piece. Bohemianism meant a life lived for art, it meant sexual liberation and freedom from social constraint, but it also meant dodging the landlord and burning your poems to stay warm. How did the garret-philosophy of the Parisian Latin Quarter take over the drawing rooms of Bloomsbury and Chelsea, and why did a French war with necessity emerge as a British life-style as art? With Hermione Lee, Goldsmiths' Professor of English Literature at the University of Oxford and biographer of Virginia Woolf; Virginia Nicholson, author of Among the Bohemians: Experiments in Living 1900-1939; Graham Robb, writer and biographer of Balzac, Victor Hugo and Rimbaud.

Folge vom 02.10.2003MaxwellMelvyn Bragg and guests discusses the life and ideas of James Clerk Maxwell whose work is not widely known, but whose genius and contribution to the age in which we live is enormous.He took the first colour photograph, defined the nature of gases and with a few mathematical equations expressed all the fundamental laws of light, electricity and magnetism - and in doing so he provided the tools to create the technological age, from radar to radio and televisions to mobile phones. He is credited with fundamentally changing our view of reality, so much so that Albert Einstein said, “One scientific epoch ended and another began with James Clerk Maxwell”. But who was James Clerk Maxwell? What were his ideas, and does this nineteenth century ‘natural philosopher’ deserve a place alongside Newton and Einstein in the pantheon of science? With Simon Schaffer, Reader in History and Philosophy of Science at the University of Cambridge; Peter Harman, Professor of the History of Science at Lancaster University and editor of The Scientific Letters and Papers of James Clerk Maxwell; Joanna Haigh, Professor of Atmospheric Physics at Imperial College London.
