ABSTRACT
This chapter presents a geographer Torsten Hagerstrand for the research into the human aspects of space and time has inspired a whole generation of geographers. Now the explicit examination of the constraints of time and space on people's lives has long been the subject of research of a group of Swedish geographers led, once again by Torsten Hagerstrand of Lund. Time and space are human constructs, so of course they must have human meaning. Things important for human beings happen through time and over space and we begin to understand why geographers are fascinated by processes of spatial diffusion in which these basic dimensions both allow and constrain what we do. Injecting an explicit and formal consideration of time into the more traditional concern for geographic space has almost become a hallmark of modern geographic studies focusing their attention on processes, developments and change.
