For well over a decade, the study of 'things in motion' has been at the centre of historical study. Nowhere is this more the case than in history of science, where materiality and circulation are in danger of becoming buzzwords in writing about science as a global phenomena. This lecture examines some of the key issues and problems in the current state of the literature. In particular, Jim Secord argues that there are potential pitfalls in the current stress on 'circulation'--particularly when the things that are circulating are objects of scientific knowledge.
