The inside story of the tech entrepreneurs who created the social media app Twitter. At first the site grew on the back of celebrities who realised it offered them a direct way to communicate with fans. After going global, it seemed to be fulfilling the founders' dream of a digital utopia where all voices would be heard. But as hate speech and misinformation flooded the platform, the founders faced growing problems to control it - and the sale to Elon Musk in 2022 represented the end of their dream.

Whether serving as Christian church, Islamic mosque, or secular museum, Hagia Sophia and its soaring dome have inspired reverence and awe. For 800 years, it was the largest enclosed building in the world—the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets. Follow engineers as they build a massive 8-ton model of the building's core structure, place it on a motorized shake table, and hit it with a series of simulated quakes, pushing it collapse—a fate that the team is determined to avoid with the real building.

A majestic presence, towering over Paris for more than 130 years, the Eiffel Tower is an iconic symbol of 19th-century progress and grandeur. When it was built for the 1889 Paris world's fair, its creator, Gustave Eiffel, was at the height of his fame and ready to take on the dream of every engineer and architect - to build the world's tallest man-made structure. He had just two years, two months and five days to erect his 300-metre iron colossus. Drawing on three decades of civil engineering innovation and works across the globe, Eiffel, a magician of iron building, was perfectly poised for this extraordinary feat.

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.
