Peter J. Ratcliffe shared the 2019 Nobel Prize in Physiology or Medicine for his work on oxygen sensing in animal cells. He directs research institutes in London and Oxford. In this episode, he reveals the interplay between dissociation – daydreaming – and interaction with colleagues as a major source of his scientific creativity. He emphasizes that to make an important discovery, you must define your own question, even as everyone – from colleagues to editors and funders – will try to convince you otherwise. We discuss how too much planning can make you unhappy, and how everyone overestimates the information transfer in lectures and presentations.
