This weeks guest is Greg Radick, Professor of History and Philosophy of Science at the University of Leeds. In the podcast Greg discusses the use of counterfactuals in history of science - the term we use for asking ‘What if?’ questions about history - and their potential to subvert our conventional thinking.  In Greg’s research, a central counterfactual question is: “What might biology be like now if a different side had triumphed in early debates on genetics?” From this seemingly simple ‘what if?’ question a fruitful range of new research options open up.
