Robert Peston learns quantum physics
He is an expert on all things business, but over the past few weeks Robert Peston has been broadening his CV.
Listeners to Radio 4's PM programme have been teaching the BBC's business editor about landscape painting, Punch and Judy and even Mandarin.
Now he is taking on quantum physics, with the help of science writer Brian Clegg, who invited Robert to the Science Museum archive at Wroughton in Wiltshire.
To hear more about Peston's adventures in quantum, listen to Wednesday's PM programme at 1700BST on Radio 4.
