4 Real Inventions Inspired by Science Fiction

From the Stone Age to the Silicon Age, materials have helped drive forward our civilisation. By manipulating materials we have been able to transform our world and our lives - and never more so than in the past century when we have discovered and designed more materials than at any other time in human history. (Part 3: Ceramic) Professor Mark Miodownik traces the story of ceramics. He looks at how we started with simple clay, sand and rock and changed them into pottery, glass and concrete - materials that would allow us to build cities, transform the way we view our world and communicate at the speed of light. Deep within their inner structure Mark discovers some of ceramics' most intriguing secrets. He reveals why glass can be utterly transparent, why concrete continues to harden for hundreds of years and how cooling ceramics could transform the way we power cities of the future.

The promise of quantum computers is that what would otherwise take a billion years to calculate, could be done in a few seconds. First-generation quantum computers have started to appear. Indeed, earlier this year, Google bought one, The D-Wave 2. How will this advance change our future lives?

Mike Wooldridge grapples with the future of AI in the third and final Christmas lecture. Mike takes a ride in a driverless car. Autonomous vehicles, once a science fiction dream, are now a reality. Many AI researchers believe removing human drivers will eventually make our streets much safer. Mike explores how the car ‘sees' and perceives the world – and how with the help of AI, it gets better the more it drives. Although AI will create many exciting opportunities, advances in AI have raised fears – some justified, others not. With the help of expert guests, Mike talks us through some of the risks AI poses. He unpacks the very real danger of bias in AI, asking how we avoid creating AI that favours those who resemble its creators, and he explores the dangers of 'fake news' and how AI algorithms can lead to dangerous online 'echo chambers', helping to foment extreme views. Mike also demonstrates deepfake technology and asks if AI means we simply can't trust our eyes any more? The prospect of super-intelligent AI means that in the future we may be able to mobilise AI to uncover radical large-scale solutions to the biggest problems facing humanity, such as climate change. But we need to think carefully about what we want to let AI control. Could AI in charge of weapons accidentally begin wars – and present a risk to our survival? And, as AI gets ever more intelligent, how should we treat it? How does our audience feel about kicking an AI robot dog? This lecture addresses the big question of AI: can it ever truly be like us, or are humans unique? As AI advances, it seems these ethical questions are destined to get ever more complex… The Christmas Lectures are the most prestigious event in the Royal Institution calendar, dating from 1825 when Michael Faraday founded the series. They are the world's longest running science television series, and always promise to inspire and amaze each year through explosive demonstrations and interactive experiments with the live theatre audience.

Imagine a world without the power to capture or transmit sound. Journey with Steven Johnson to the Arcy sur Cure caves in northern France, where he finds the first traces of the desire to record sound — 30,000 years ago. He also learns about the difference that radio made in the civil rights movement and reveals the Hollywood star who designed a WW2 weapon that would make possible the modern cell phone network. During an ultrasound on a pregnant dolphin, he realizes just how big a role sound has played in medicine. The unsung heroes of sound have had an impact on our working lives, race relations, saving lives and the radical alteration of cities.
