In this episode Brian uncovers how the stunning diversity of shapes in the natural world are shadows of the rules that govern the universe. In Spain he shows how an attempt by hundreds of people to build the highest human tower reveals the force that shapes our planet. In Nepal, honey hunters seek out giant beehives that cling to cliff walls. The perfect hexagonal honeycombs made by the bees to store their honey conceal a mathematical rule. Off the coast of Canada, Brian explains how some of the most irregular, dangerous shapes in nature - massive icebergs that surge down from Greenland and into shipping lanes of the Atlantic - emerge from a powerful yet infinitely small force of nature. Even the most delicate six-sided snowflake tells a story of the forces of nature that forged it.

Dr Hannah Fry explores the limits of our control, from dangerous miscalculations to creating and spotting fake videos, and questions how far we should be going with our mathematical skills. A gravity-defying BMX stunt kick-starts the debate around trusting the numbers, and launches us into an investigation of just how sure we can be about anything in our messy world. Together with maths comedian Matt Parker, Hannah uses flaming balloons and gigantic slices of melting cheese to get to the bottom of the guesswork used in real world calculations. A visiting drone zips through the corridors of the historic Royal Institution building, introducing the mother of all drones, a human-sized machine that delivers urgent parcels, and we welcome the team designing driverless helicopters and buying up London rooftops to prepare for the future. But these physical challenges are just the beginning of the debate on handing control over to machines. Hannah explores whether human jurors or robots make fairer decisions, and welcomes Atima Lui, who is on a mission to design the most unbiased facial detection software in the world, which will say goodbye to the 'fast track for white people' at automatic passport gates. Hannah dives into the issues around privacy in our modern world, with Glow Up make-up star Tiffany Hunt making a member of the audience invisible to CCTV, while Hannah explores the truth behind cookies and anonymity online. Finally, she delves into the world of fake news, to separate the truth from the lies. Leading deep fake creators team up with the Christmas Lectures to create a television first – a custom-made deep fake video of a child in the audience, highlighting our ability to use maths to warp reality however we please. Hannah ultimately explores who the real winners are, in an escalating arms race of mathematical tricks.
S1E3 • Royal Institution Christmas Lectures: Secrets and Lies - The Hidden Power of Maths • 2019 • Math
Documentary that reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age. In 1943 a 24-year-old maths student and a GPO engineer combined to hack into Hitler's personal super code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognised.

The disaster began during a routine systems test at reactor number four of the Chernobyl plant located near the town of Pripyat, on April 26, 1986. After a power surge, an emergency shutdown was attempted and after a subsequent power spike, there was a reactor vessel rupture and a series of steam explosions. The cascading course of events led to exposing the graphite moderator of the reactor to the air, causing it to catch fire. This sent a plume of highly radioactive fallout into the atmosphere. The fallout from Chernobyl prompted mass evacuations as it drifted over an extensive geographical area, including the western Soviet Union and Europe. Over 350,000 people were resettled from contaminated areas of Belarus, Russia, and the Ukraine. Thirty-one deaths are directly attributed to the accident, and all the deaths were among reactor staff and emergency workers. This is the kind of atmosphere Nelson and Ochota are investigating on Life After: Chernobyl as they attempt to determine how the radiation continues to impact the affected areas. They are allowed to stay for as long as they need to in order to conduct their ground-breaking research, but the duo must also be sure to take the necessary safety precautions. Broadway World noted in their Life After: Chernobyl article that by staying in the area for too long, the radiation exposure could reach dangerously high levels in their bodies, and they must always monitor the radiation levels.

John Eliot Gardiner goes in search of Bach the man and the musician. The famous portrait of Bach portrays a grumpy 62-year-old man in a wig and formal coat, yet his greatest works were composed 20 years earlier in an almost unrivalled blaze of creativity. We reveal a complex and passionate artist; a warm and convivial family man at the same time a rebellious spirit struggling with the hierarchies of state and church who wrote timeless music that is today known world-wide. Gardiner undertakes a 'Bach Tour' of Germany, and sifts the relatively few clues we have - some newly-found. Most of all, he uses the music to reveal the real Bach.
