Historically, the success of science has been rooted in the concept of breaking down systems into their fundamental units. However, in order to comprehend complex structures, it is necessary to adopt a perspective that allows us to grasp the interconnectedness of the elements comprising them. This serves as the foundation for the book “At the Mercy of the Networks” by Ernesto Estrada, a research professor at the Higher Council for Scientific Research (CSIC) at the Institute of Interdisciplinary Physics and Complex Systems.
In his book, Estrada explores the mathematical object known as the network or graph, which simplifies
