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?

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?
