خلاصه	Time geography is a framework, introduced by Torsten Hägerstrand in 1970, that represents human activity as continuous trajectories through a joint space-time coordinate system rather than as static points on a map. Each individual traces a space-time path through the 'space-time aquarium', and the set of all locations that can be reached and returned from within a time budget forms a space-time prism, whose spatial footprint is the potential path area. The framework grounds accessibility and mobility in the inescapable fact that people can be in only one place at a time and that movement consumes both space and time.	The space-time cube is a framework from time geography for representing and analyzing phenomena that move and change over both space and time. Two horizontal axes carry geographic location and a vertical axis carries time, so each observation becomes a point in a three-dimensional x–y–t volume and a moving object traces a continuous 'space-time path' through the cube. Introduced conceptually by Torsten Hägerstrand in 1970 and turned into a practical analytic and cartographic tool by Menno-Jan Kraak, it underpins modern spatiotemporal hot-spot and trajectory analysis.
