One To One

How do different people look at the world around them? Do a scientist and an artist see a sunset the same way? In the first of two programmes, we meet the Nobel prize winning astrophysicist, John Mather. Dr Mather is the Senior Project Scientist on the James Webb Space Telescope, the successor to the Hubble. He talks to the journalist Jay Elwes about the "telescope of the imagination", and how technology can help us look back through space and time to picture our universe in its early days.
