Unformatted text preview: - space-time convergence ( shrinkage)- changes pattern of interaction- globalization III. Gravity Models A. Intro to Computational Modeling In Geography- represent part of system and their relationships Mathematical equations/ programs Simulation- simplified representation- critical- sometimes simplifications almost absurd Reality is very complex- simplification = tool used to break down that complexity ( understand complexity = dont consider it complex) Principle of Parsimony- tenant of scientific philosophy- means simplest explanation that works = best- output of simulation = observations of reality ( differential & simulation) B. Simple Gravity Model- interaction between places 2 simple factors- distance- places ( attractiveness) * some places attract people regardless of distance Formulas: C. Retail Gravitational Models Reillys Breaking Point Model- boundary between two functions Formula:...
