Network science is the field dedicated to the investigation and analysis of complex systems via their representations as networks.
This deceptively simple object is the starting point of never-ending complexity, due to its ability to represent almost every facet of reality: chemical interactions, protein pathways inside cells, neural connections inside the brain, scien.
We normally model such networks as graphs: sets of nodes connected by sets of edges and a number of node and edge attributes.
