The gravity model of migration is a model in urban geography derived from Newton's law of gravity, and used to predict the degree of migration interaction between two places. [1] In 1941, astrophysicist John Q. Stewart [ 2 ] applied Newton's law to the social sciences, establishing a theoretical foundation for the field of social physics.

English: This Erdős–Rényi model is generated with N=5 nodes. For each edge in the complete graph formed by all N nodes, a random number is generated and compared to a given probability. If the random number is greater than p, an edge is formed on the model.
More recent geographers have tried to combine time geography with the qualitative research and affective phenomenology of feminist geography. [ 16 ] Development of Hägerstrand's work has continued to form part of the basis for non-representational theory , and a reappraisal of his work by new generations of social scientists [ 17 ] and ...
They do not account for the formation of hubs. Formally, the degree distribution of ER graphs converges to a Poisson distribution, rather than a power law observed in many real-world, scale-free networks. [3] The Watts and Strogatz model was designed as the simplest possible model that addresses the first of the two limitations. It accounts for ...
