Professor of physics Jim Al-Khalili investigates the most accurate and yet perplexing scientific theory ever - quantum physics.

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.

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

Dr Adam Rutherford explores the consequences of one of the biggest scientific projects of all time - the decoding of the entire human genome.

It happened more or less by accident; the people who made it happen were amateurs; and for the most part they still are. From his own Silicon Valley garage, author Bob Cringley puts PC bigshots and nerds on the spot, and tells their incredible true stories. Like the industry itself, the series is informative, funny and brash.

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.

Physicist Jim Al-Khalili as he shows us how science gives us insight into the biggest questions of all. How did the universe come into being? How did life start on Earth, and how does it sustain itself? What is the nature of space and time – and how will it all end?

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?

From the award-winning team that brought you The Secret Life of Chaos comes a unique television event on the physics of gravity.

Professor Jim Al-Khalili unravels the mysteries of arguably the most complex object in the cosmos: the human brain.

Oak Tree: Nature's Greatest Survivor. In this landmark new BBC documentary, entomologist George McGavin takes us on a fascinating journey through a year in the life of a 400-year-old oak tree.

Hormones shape each and every one of us, affecting almost every aspect of our lives - our height, our weight, our appetites, how we grow and reproduce, and even how we behave and feel. This documentary tells the wonderful and often weird story of how hormones were discovered. Presenter John Wass, one the country's leading experts on hormones, relates some amazing stories - how as recently as the 19th century boys were castrated to keep their pure soprano voice, how juices were extracted from testicles in the hope they would rejuvenate old men and how true medical heroes like Frederick Banting discovered a way to make insulin, thus saving the lives of countless diabetes sufferers.

Physicist Dr Helen Czerski takes us on a journey into the science of bubbles - not just fun toys, but also powerful tools that push back the boundaries of science.

Expert John Wass presents a documentary telling the story of how hormones were discovered and remain at medicine's cutting edge as we try to deal with modern scourges like obesity.

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.
