The theory of the small world or effect of the small world is a mathematical and sociological theory that
claims that all complex networks present in nature are such that any two nodes can be connected by a path
consisting of a relatively small number of connections. Mathematically, the theory is studied as a branch
of graph theory, particularly in computer science, with applications, for example, biology, economics and
sociology.
Sometimes it is referred to as the theory of the six degrees of separation. The first formulation of the concept
dates back to the book Chains (1929) by the Hungarian writer Frigyes Karinthy.
