With input from an eclectic mix of scientists, engineers, sportspeople (and about thirty thousand snails) the film focuses on the many incarnations of speed and how it affects us all on land, sea, sky, space and even in our thoughts.

Like all great science fiction shows, there are kernels of truth and nuggets of science fact scattered throughout the incredible ‘Doctor Who’ universe. In this special, we are going to explore these dynamic ‘Doctor Who’ moments where science fiction and science fact converge and mingle.

For one night only, Professor Brian Cox takes an audience of celebrity guests and members of the public on a journey into the wonderful universe of the Doctor, from the lecture hall of the Royal Institution of Great Britain. Drawing on the latest theories as well as 200 years of scientific discoveries and the genius of Einstein, Brian tries to answer the classic questions raised by the Doctor. Can you really travel in time? Does extra-terrestrial life exist in our galaxy? And how do you build something as fantastical as the TARDIS?

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.

Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries.

Prof. Jim Al-Khalili tackles the biggest subject of all, the universe. Through a series of critical observations and experiments that revolutionised our understanding of our world Jim guides us through the greatest cosmic detective story of all. He takes us from the beginning of the universe to the end time and answers the question: where did the universe come from and how will it 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?

Professor Jim Al-Khalili investigates the amazing science of gravity. As well sculpting our universe, gravity also affects our weight, height and even the rate at which we age.

From the award-winning British team that brought you Everything and Nothing and The Secret Life of Chaos comes a unique television event on the physics of gravity. This film features unexpected historical insights, cutting-edge science and exciting new experiments. From Einstein's Relativity to quantum mechanics, host Jim Al-Khalili explores one of the most extraordinary phenomena in our universe.

Lying on the remote north west coast of England is one of the most secret places in the country - Sellafield, the most controversial nuclear facility in Britain. Now, Sellafield are letting nuclear physicist Professor Jim Al-Khalili and the television cameras in to discover the real story. Inside, Jim encounters some of the most dangerous substances on earth, reveals the nature of radiation and even attempts to split the atom. He sees inside a nuclear reactor, glimpses one of the rarest elements in the world - radioactive plutonium - and even subjects living tissue to deadly radiation. Ultimately, the film reveals Britain's attempts - past, present and future - to harness the almost limitless power of the atom.
