1 I (Why do certain scientific concepts lead a nomadic life, from one science to the next? What do they become as they travel from a ‘hard’ science to a ‘soft’ science, or the other way round? Does their meaning stay the same? Do they help to unify the field of the sciences? Or do they rather complicate the picture?( Isabelle Stengers*)
