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.

Built around the earliest, until now unseen, footage of the Clash in concert, filmed by Julien Temple as they opened the infamous Roxy club in a dilapidated Covent Garden on January 1st 1977, this show takes us on a time-travelling trip back to that strange planet that was Great Britain in the late 1970s and the moment when punk emerged into the mainstream consciousness. Featuring the voices of Joe Strummer and the Clash from the time, and intercutting the raw and visceral footage of this iconic show, with telling moments from the BBC's New Year's Eve, Hogmanay and New Year's Day schedules of nearly 40 years ago, it celebrates that great enduring British custom of getting together, en masse and often substantially the worse for wear, to usher in the New Year.

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.
