The concept of mobility has grown enormously over the last two decades. A large part of the social sciences has been interested in the different forms of mobility, from a wide variety of spatial and temporal scales. This book presents the different spatial and temporal scales of mobility and the way in which they form a system, by associating them with essential and original research objects. It provides an in-depth review of scientific knowledge, a perspective on major societal issues, analytical tools and a discussion on the main current academic debates. The authors highlight the need to take into account both the spatial and temporal scales of mobility in order to address contemporary environmental and societal issues. The book invites us to think about the entanglement of these different scales from the analysis of rhythms by founding a rhythmology of contemporary mobilities.
