Professor Jim Al-Khalili looks at how we have created machines that can simulate, augment, and even outperform the human mind - and why we shouldn't let this spook us. He reveals the story of the pursuit of AI, the emergence of machine learning and the recent breakthroughs brought about by artificial neural networks. He shows how AI is not only changing our world but also challenging our very ideas of intelligence and consciousness. Along the way, we'll investigate spam filters, meet a cutting-edge chatbot, look at why a few altered pixels makes a computer think it's looking at a trombone rather than a dog and talk to Demis Hassabis, who heads DeepMind and whose stated mission is to 'solve intelligence, and then use that to solve everything else'. Stephen Hawking remarked 'AI could be the biggest event in the history of our civilisation. Or the worst'. Jim argues that AI is a potent new tool that should enhance our lives, not replace us.

In 1919 an art school opened in Germany that would change the world forever. It was called the Bauhaus. A century later, its radical thinking still shapes our lives today. Bauhaus 100 is the story of Walter Gropius, architect and founder of the Bauhaus, and the teachers and students he gathered to form this influential school. Traumatised by his experiences during the Great War, and determined that technology should never again be used for destruction, Gropius decided to reinvent the way art and design were taught. At the Bauhaus, all the disciplines would come together to create the buildings of the future, and define a new way of living in the modern world.

Dr. Zhivago is one of the best-known love stories of the 20th century, but the setting of the book also made it famous. It is a tale of passion and fear, set against a backdrop of revolution and violence.

In this documentary, Stephen Smith traces the revolutionary beginnings of this bestseller, to it becoming a pawn of the CIA at the height of the Cold War.

Over twenty-five years after his death in July 1989, the controversial Austrian conductor Herbert von Karajan remains an enigma. He was the most successful conductor in the history of classical music. Many of his recordings - of Italian opera, of Wagner and Richard Strauss, of Sibelius, Beethoven and Brahms - are treasured by music lovers around the world. Yet, even at the peak of his fame, his performances were variously criticised for being too opulent, too manicured, lacking warmth or spiritual depth. This musical profile explores the many paradoxes in the life and music of this controversial figure, who forged his international reputation in London with the Philharmonia Orchestra shortly after the end of the Second World War and went on to reign supreme in the classical music world during his three decades with the Berlin Philharmonic. The film also examines Karajan's belief in the visual power of music, and his determination to leave behind a substantial legacy of music on film.
