Small-World Phenomenon: Six Degrees of Separation
Explores the counterintuitive property of networks where most nodes are not neighbors but can be reached from every other node by a small number of hops or steps.
Network Theory
A branch of graph theory in mathematics and a field of applied mathematics that studies complex systems through the lens of nodes, edges, and connectivity patterns. Fundamental to understanding everything from social structures to neural pathways and the internet.
