Beginning in Ethiopia, Professor Brian Cox discovers how the universe played a key role in our ascent from apeman to spaceman by driving the expansion of our brains. But big brains alone did not get us to space.

Brian Cox reveals how the wonderful complexity of nature and human life is simply the consequence of chance events constrained by the laws of physics that govern our universe. But this leads him to a deeper question - why does our universe seem to have been set up with just the right rules to create us?

Professor Brian Cox explores our origins, place and destiny in the universe. We all start our lives thinking that we are at the centre of the universe, surrounded by our family and the world as it spins around us. But the urge to explore is strong.

What is our future/destiny?

Professor Brian Cox explores the most precious, most wonderful thing in the universe, us.

James Hunt has never been equalled. Could swashbuckling Hunt catch the scientific Lauda? Could Niki overcome an appalling crash to come back from the dead and fight James all the way to the last race of the season?

Using cutting edge visual effects and CGI, this scientific visual extravaganza creates the first accurate non-stop journey from here to the edge of the universe

How atomic theories and concepts of quantum physics underpin modern technology.

Two-part series in which Professor Jim Al-Khalili shows how, by uncovering its secrets, scientists have used light to reveal almost everything we know about the universe.

Professor Jim Al-Khalili tells the story of how we went from thinking we were close to a complete understanding of the universe to realising we had seen almost none of it. Today, our best estimate is that more than 99 per cent of the cosmos is hidden in the dark, invisible to our telescopes and beyond our comprehension.

A piece of metal that defines the mass of a kilogramme has, over time, lost the equivalent of the weight of an eyelash. What are the consequences for how we measure our world?

Who was this man who embodies like no other triumph and tragedy of the 20th century? And what he has to say to us today? "Myth Einstein" embarks on a journey through the life of the physicist and feel the true and invented stories about the genius after.

Albert Einstein ist ein Popstar der Wissenschaft, um den sich etliche Legenden ranken. Erst posthum treten mit der Herausgabe privater Dokumente die nicht nur strahlenden Seiten des Jahrhundert-Genies ans Licht. Wer war dieser Mann, der wie kein anderer Triumph und Tragik des 20. Jahrhunderts verkörpert hat? Und was hat er uns heute noch zu sagen? "Mythos Einstein" begibt sich auf eine Reise durch das Leben des Physikers und spürt den wahren und erfundenen Geschichten um das Genie nach.

Right now you're hurtling around the Sun at a hundred thousand kilometres an hour. Join Kate Humble and Dr Helen Czerski as they explore the relationship between the Earth's orbit and the weather

Right now you're hurtling around the sun at 64,000 miles an hour (100,000 kms an hour). In the next year you'll travel 584 million miles, to end up back where you started. Presenters Kate Humble and Dr Helen Czerski follow the Earth's voyage around the sun for one complete orbit, to witness the astonishing consequences this journey has for us all. In this first episode they travel from July to the December solstice, experiencing spectacular weather and the largest tides on Earth. To show how the Earth's orbit affects our lives, Helen jumps out of an aeroplane and Kate briefly becomes the fastest driver on Earth.

In this final episode we complete our journey, travelling back from the March equinox to the end of June. Kate Humble is in the Arctic at a place where spring arrives with a bang, whilst Helen Czerski chases a tornado to show how the earth's angle of tilt creates the most extreme weather on earth.

In this second episode we travel from January to the March equinox. Kate Humble gets closer to the Sun than she has ever been before, whilst Helen Czerski visits a place that gets some of the biggest and fastest snowstorms on Earth.

Professor Jim Al-Khalili discovers the intriguing story of how we discovered the rules that drive the universe. Energy is vital to us all, but what exactly is energy?

Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science.

From lightning bolts and watt engines to electromagnetic waves and single electrons, Professor Marcus du Sautoy continues his journey into the world of measurement as he reveals how we came to measure and harness the power of heat, light and electricity.

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

Professor Iain Stewart reveals the story behind the Scottish physicist who was Einstein's hero; James Clerk Maxwell. Maxwell's discoveries not only inspired Einstein, but they helped shape our modern world - allowing the development of radio, TV, mobile phones and much more.

What would the universe look like if you were a billion times smaller or a billion times bigger? In this mind-bending series, Jim Al-Khalili will look at the universe across its vast range of size.

At an even greater scale, Jim encounters huge structures such as the Laniakea Supercluster, of which the Milky Way is only a tiny part.
