In an ideal (quantum) world, Jim Al-Khalili would be interviewing himself about his life as a scientist but since the production team can’t access a parallel universe, Adam Rutherford is stepping in to ask Jim questions in front of an audience at The Royal Society. Jim and his family left Iraq in 1979, two weeks before Saddam Hussein came to power, abandoning most of their possessions.

Having grown up listening to the BBC World Service, he had to drop his ts to fit in at school in Portsmouth where he was one of just three boys in a class of more than a hundred girls. He specialised in nuclear physics and spent fifteen years in front of a computer screen trying to understand an exotic and ephemeral sub-atomic phenomenon known as the halo effect. His ‘little eureka moment’ came in 1996 when Jim discovered that, for the mathematics to add up, these halo nuclei had to be a lot bigger than anyone had thought. It isn’t going to lead to a new kind of non-stick frying pan any time soon but it was exciting, nonetheless. More recently he has become interested in quantum biology. It started as a hobby back in the 1990s when physicists were sceptical and many biologists were unconvinced. Since then evidence has been stacking up. Several studies suggest that lasting quantum mechanical effects could explain photosynthesis, for example. 'It maybe a red herring’ Jim admits but Jim and his team at the University of Surrey are determined to find out if the idea of quantum biology makes sense. Could life itself depend on quantum tunnelling and other bizarre features of the sub-atomic world?
