Richard Clay, art historian and expert on semiotics and iconoclasm and the interplay between new technology and shifts in meaning, compares and contrasts cultural symbols from across the centuries, unpicking iconic images, music, and other cultural outputs to explain where ‘stickiness’ comes from.
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.

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 1: Metal) Professor Mark Miodownik travels to Israel to trace the history of our love affair with gleaming, lustrous metal. He learns how we first extracted glinting copper from dull rock and used it to shape our world and reveals how our eternal quest for lighter, stronger metals led us to forge hard, sharp steel from malleable iron and to create complex alloys in order to conquer the skies. He investigates metals at the atomic level to reveal mysterious properties such as why they get stronger when they are hit, and he discovers how metal crystals can be grown to survive inside one of our most extreme environments - the jet engine.
Two air catastrophes within five months of each other, both involving the same plane: the Boeing 737 MAX. How could these brand-new passenger jets, built by one of aviation's most trusted companies, just fall out of the sky? Now, through newly uncovered records, plus interviews with experts who investigated the crashes, we reveal why this seemingly reliable aircraft was headed toward disaster from the very beginning, and list the series of miscalculations, mistakes, and fraudulent maneuvers that sent 346 people to their deaths in 2018 and 2019.
NOVA takes you inside the historic international race to develop the first supersonic airliner, the Concorde. Hear stories from those inside the choreographed effort to design and build Concorde in two countries at once—and the crew members who flew her. Then, follow Concorde’s legacy to a new generation of innovators reviving the dream of supersonic passenger travel today.
Explore the hidden history and super science of hot air balloons, synthetic rubber and metal detectors.
