Cheltenham Science Festival Special

Why virtual reality is coming of age and whether it’s a good idea to treat robots like humans are among the topics we talk about in a special show from Europe’s biggest science festival. Presented by Rory Cellan-Jones, with special guests Professor Jim Al-Khalili, British theoretical physicist, author and broadcaster, and Louise Emerson, CEO of Cheltenham Festivals.
