Geim says of his approach to science: ‘I jump from one research subject to another every few years. I do not want to study the same stuff “from cradle to coffin”, as some academics do. To be able to do this, we often carry out what I call “hit-and-run experiments”, crazy ideas that should never work and, of course, they don’t in most cases. However, sometimes we find a pearl . . . This research style may sound appealing but it is very hard psychologically, mentally, physically, and in terms of research grants, too. But it is fun.’
