It was odd listening to Jim Al-Khalili being interviewed on Radio 4 on Tuesday morning rather than the other way round. In his series The Life Scientific, Al-Khalili has developed his own brand of interviewing, encouraging his guests to talk about their work in science by leading them from personal biography —how they came to study science, what they were like at school, who influenced them — to the intricacies of their research and why we should know about it.
