In Our Time With Melvyn Bragg Folgen

Melvyn 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?

Melvyn 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.

Melvyn Bragg and guests discuss the medieval kingdom of Bohemia which was at the crossroads of Europe and, during the 15th century, at the heart of the Holy Roman Empire. Under Charles IV, its cosmopolitan capital Prague became a cultural and intellectual centre, attracting scholars and artists from all over Europe. But Prague was awash with religious and political dissent. At its core stood the anarchist philosopher Jan Hus, whose ideas anticipated the Lutheran Reformation by a full century. He was burnt at the stake, but his followers, the Hussites, embarked on a series of wars that continue to mark the Czech and German characters even today. Why was Bohemia such a crucible of dissent and how were its ideas exported to the rest of Europe? What did it mean to be Bohemian then and how was the ancient kingdom of Bohemia, with its ferment of religious, national and ethnic ideologies, divided up to form the states of modern Central Europe? With Norman Davies, Professor Emeritus, University of London; Karin Friedrich, Lecturer in History, School of Slavonic and East European Studies, University College London; Robert Pynsent, Professor of Czech and Slovak Literature, University College London.
