Introduction      LS Logic      Evolving theory      Applications

The initial step in explaining the logic of LS is to show why space-time coordinates qualify or determine the state of properties of an object. If we start with a plant as an example, it is a fact that plant genotypes have different levels of adaptation to different environmental conditions. Environmental conditions vary dramatically across the space-time dimension. As we move from the tropics to temperate zones the productivity and types of plants vary and in some locations, deserts and the polar caps, cannot survive. In any specific region, if there is a hill or mountain, there is a roughly 0.6oC drop in temperature for every 100m gain in altitude. This has the effect of altering the timing of the stages of growth and reproduction observed for any naturally occurring plant genotypes according to where they might be located in a valley or mountain. These distance transitions are very well known in ecological work and in soil science (pedology) these transitions are typical of changes in soil texture and structure affecting water availability and fertility, generally known as a catena (the transition from a high elevation down into a valley, for example). The reference to plants located at different altitudes relates to naturally occurring genotypes so that the seeding, growth and flowering cycles would occur according to the ambient temperature conditions at the different altitudes. However, these natural locational-states can be altered by farmers planting a seedling before the time this would occur according to the normal reproductive cycle. This results in the state of growth of that genotype being different from the others occurring naturally. This effective can be more dramatic as a result of plant selection resulting from breeding activities. The interesting point is that this does not "break up" the location-state theory because the differences observed can be explained in terms of the space-time dimension, that is, in terms of the specific age of the plant concerned. Therefore the cumulative impact of space-time can be recognized in the hierarchy of natural cycles of ever shortening duration that have a direct influence the properties of objects (see diagram right).

The One of the interesting facts behind Charles Darwin's theory of evolution was that he first became interested in "change" after reading texts of geology and later observing the transition in geological formations associated with their age. Moving away from the natural world we know that an automobile of a specific age will survive in operational condition according to its environment represented by the levels of maintenance, the skills of the driver and general treatment of the vehicle.

Locational-state logic has a wide application in statistical analysis.
