In Our Time Folgen
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 16.05.2002Chaos TheoryMelvyn Bragg examines whether world is a fundamentally chaotic or orderly place. When Newton published his Principia Mathematica in 1687 his work was founded on one simple message: Nature has laws and we can find them. His explanation of the movements of the planets, and of gravity, was rooted in the principle that the universe functions like a machine and its patterns are predictable. Newton’s equations not only explained why night follows day but, importantly, predicted that night would continue to follow day for evermore. Three hundred years later Newton’s principles were thrown into question by a dread word that represented the antithesis of his vision of order: that word was Chaos. According to Chaos Theory, the world is far more complicated than was previously thought. Instead of the future of the universe being irredeemably fixed, we are, in fact, subject to the whims of random unpredictability. Tiny actions can change the world by setting off an infinite chain of reactions: famously, if a butterfly flaps its wings in Brazil - it could cause a tornado in Berlin. So what’s the answer? Is the universe chaotic or orderly? If it’s all so complicated, why does night still follow day? And what is going on in that most complex machine of all - the brain - to filter and construct our perception of the world?

Folge vom 09.05.2002The Examined LifeMelvyn Bragg and guests discuss self-examination. Socrates, the Greek philosopher of the 4th century BC, famously declared that "The unexamined life is not worth living." His drive towards rigorous self-enquiry and his uncompromising questioning of assumptions laid firm foundations for the history of Western Philosophy. But these qualities did not make him popular in ancient Athens: Socrates was deemed to be a dangerous subversive for his crime, as he described it, of "asking questions and searching into myself and other men". In 399 BC Socrates was sentenced to death on the charge of being "an evil-doer and a curious person". Two thousand years later, the novelist George Eliot was moved to reply to Socrates that "The unexamined life may not be worth living, but the life too closely examined may not be lived at all". For Eliot too much self-scrutiny could lead to paralysis rather than clarity. What did Socrates mean by his injunction? How have our preoccupations about how to live altered since the birth of ancient Greek philosophy? And where does philosophy rank in our quest for self-knowledge alongside science, the arts and religion? With Dr Anthony Grayling, Reader in Philosophy, Birkbeck, University of London; Janet Radcliffe Richards, Philosopher of Science and Reader in Bioethics, University College, London; Julian Baggini, Editor, The Philosopher’s Magazine and co-editor of New British Philosophy: The Interviews.

Folge vom 02.05.2002The Physics of RealityMelvyn Bragg examines the physics of reality. When Quantum Mechanics was developed in the early 20th century reality changed forever. In the quantum world particles could be in two places at once, they disappeared for no reason and reappeared in unpredictable locations, they even acted differently according to whether we were watching them. It was so shocking that Erwin Schrodinger, one of the founders of Quantum Theory, said "I don’t like it and I'm sorry I ever had anything to do with it." He even developed an experiment with a cat to show how absurd it was. Quantum Theory was absurd, it disagreed with the classical physics of Newton and Einstein and it clashed with our experience of the everyday world. Footballs do not disappear without reason, cats do not split into two and shoes do not act differently when we are not looking at them. Or do they? Eighty years later we are still debating whether the absurd might actually be true. But why are features of quantum physics not seen in our experience of everyday reality? Can the classical and quantum worlds be reconciled, and why should reality make sense to us? With Roger Penrose, Emeritus Rouse Ball Professor of Mathematics, Oxford University; Fay Dowker, Lecturer in Theoretical Physics, Queen Mary, University of London; Tony Sudbery, Professor of Mathematics, University of York.

Folge vom 25.04.2002TolstoyMelvyn Bragg and guests discuss the life and work of the 19th century Russian novelist Leo Tolstoy.The Russian novel has been acclaimed as one of the outstanding genres of literature alongside Greek Tragedy, Shakespeare’s Plays and Romantic Poetry. Its heyday was the mid-19th century, and its practitioners gave expression to the compelling moral and social questions of their day - and arguably of the modern era. These men of genius included Dostoevsky, Gogol and Turgenev, but perhaps the greatest of them all was Tolstoy, author of the novels War and Peace and Anna Karenina. Tolstoy took massive subjects and presented them in loving and intricate detail. As Matthew Arnold said, "a work by Tolstoy is not a piece of art but a piece of life". Possessed by an urgent desire to represent real life in his work, and to reject artifice, Tolstoy declared that "The one thing necessary in life as in art is to tell the truth." What did Tolstoy mean by telling the truth? How did he convey these truths to the reader? And why did he, ultimately, give up on literature and concentrate instead on religious and political philosophy? With A N Wilson, Novelist, journalist and biographer of Tolstoy; Catriona Kelly, Reader in Russian, Oxford University; Sarah Hudspith, Lecturer in Russian, University of Leeds.
