Space Time an Overview of Repetition

I will be giving a talk today at the London Metropolitan University at the MA Cities, Design and Urban Cultures lead by Ines Weizmann.
The topic is Time Space focusing on how the space is influenced by the cultural convention over time. If we define time as a cultural convention, in the sense of Thrift, I will ask the question of what the meaning of space can be. My Hypothesis for this talk is that both are constructed through the elements of time and place, in the sense of Tuan. An important role also plays the visualisation of the problem and I will use the well know examples by Hagerstrand and Debord to illustrate the problems surrounding the politics of temporal patterns. We will look at aspects of repetition and cycles regarding the question of contraints in the sense of Hagerstrand. His Time-Space Aquarium has widely been critisised for a number of points, and his definition of the contrains is one of them. In terms of politics of the temporal pattern I guess this aspect is crucia. Hagerstrand defines three types of constraint. Capability constraints refer to the limitations on human movement due to physical or biological factors. Thus, for example, a person cannot be in two places at one time. A person also cannot travel instantaneously from one location to another.
Coupling addresses the fact that in certain situations individuals are connected to one another, as for example in the morning rush hour.
Authority is a ‘domain’ or area that is controlled by a group or institution restricting access for other individuals or groups as in a hospital, a military base or a private club.
In an overall sense the concept of constraints refers to the possibility of an unconstrained existence. This view is fundamental to the urbanMachine, the setting were we are all users of the city as a service provided.
Aspects of creation and capacity to shape the immediate surrounding could become important in a new way to look at urban planning. In the context of current technologies and emerging applications, where temporal information, services and participation play a dominant role, I believe it would be important to rethink these static concepts.
