what is everything, and what is nothing? Professor Jim Al-Khalili explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness. EVERYTHING: what the universe might actually look like and the remarkable stories of the men and women who discovered the truth about the cosmos. NOTHING: science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim Al-Khalili can prove it.

Professor Brian Cox explores the dramatic lives of the eight majestic planets/worlds that make up our solar system.

A mind-bending, thrilling journey exploring the fragility and wonder of planet Earth, one of the most peculiar, unique places in the entire universe, brought to life by the only people to have left it behind – the world’s most well known and leading astronauts.

Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing? Professor Jim Al-Khalili searches for an answer to these questions as he explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness.

Documentary presented by Professor Simon Schaffer which charts the amazing and untold story of automata - extraordinary clockwork machines designed hundreds of years ago to mimic and recreate life. The film brings the past to life in vivid detail as we see how and why these masterpieces were built. Travelling around Europe, Simon uncovers the history of these machines and shows us some of the most spectacular examples, from an entire working automaton city to a small boy who can be programmed to write and even a device that can play chess. All the machines Simon visits show a level of technical sophistication and ambition that still amazes today.

Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here?

This subversive documentary unpacks the tricks brands use to keep their customers consuming — and the real impact they have on our lives and the world.

Professor Jim Al-Khalili investigates the important concepts of energy and information.

Alan Turing is the genius British mathematician who was instrumental in breaking the German naval Enigma Code during World War II, arguably saving millions of lives. Turing's achievements went unrecognised during his lifetime. Instead he ended up being treated as a common criminal, for being homosexual at a time when homosexual acts were a crime. In 1952, he was convicted of 'gross indecency' with another man and was forced to undergo so-called 'organo-therapy' - chemical castration. Two years later, he killed himself with cyanide, aged just 41. Alan Turing was driven to a terrible despair and early death by the nation he'd done so much to save.

The highs and lows of Alan Turing's life, tracking his extraordinary accomplishments, his government persecution through to his tragic death in 1954. In the last 18 months of his short life, Turing visited a psychiatrist, Dr. Franz Greenbaum, who tried to help him. Each therapy session in this drama documentary is based on real events. The conversations between Turing and Greenbaum explore the pivotal moments in his controversial life and examine the pressures that may have contributed to his early death. The film also includes the testimony of people who actually knew and remember Turing. Plus, this film features interviews with contemporary experts from the world of technology and high science including Apple co-founder Steve Wozniak. These contributors bring Turing's exciting impact up to the present day, explaining why, in many ways, modern technology has only just begun to explore the potential of Turing's ideas.
