Geography simply is a science by virtue of the fact that it is a truth-seeking discipline whose raw materials consist of empirical observations seeking to make law-like statements. A law should be unrestricted in its application over space and time. It is thus a "universal statement" of unrestricted range. This suggests at least one important criterion for distinguishing a law. A key concept in this respect is that laws must be proven through objective procedures and not accepted simply because they seem plausible. A valid law must predict certain patterns in the world, so that having developed an idea about those patterns; the researcher must formulate them into a testable hypothesis "a proposition whose truth or falsity is capable of being asserted". Four types of laws which have relevance for human geographer: Cross-sectional laws; Equilibrium laws; Dynamic laws and Statistical laws. Positivist-led geography has wider application of laws for successful and fruitful analysis of geographical phenomena together with spatial patterns. There are two alternative routes to explanation, or which are followed in establishing a scientific law "induction" and "deduction". Tobler"s First Law (TFL) was a product of the quantitative revolution of the 1960s, and efforts to turn geography into a nomothetic science stated that "everything is related to everything else, but near things are more related than distant things". Spatial analysis, and indeed life itself, would be impossible. Less well known is his (Tobler) second law, which complements the first: "The phenomenon external to an area of interest affects what goes on inside". Others scholars have offered up their versions of this law examples include: "Ecology" "Cognitive geography" "Political behaviour" and "Financial". The primary task of scientific method is to explain empirical phenomena, now encapsulated in geographic law and illuminated by advanced in geomatic science. TFL forms the conceptual foundation for the entire field of geostatistics and its cousins in other disciplines.
