AbstractThe interactions among human beings represent the backbone of our societies. How people establish new connections and allocate their social interactions among them can reveal a lot of our social organisation. We leverage on a recent mathematical formalisation of the Adjacent Possible space to propose a microscopic model accounting for the growth and dynamics of social networks. At the individual’s level, our model correctly reproduces the rate at which people acquire new acquaintances as well as how they allocate their interactions among existing edges. On the macroscopic side, the model reproduces the key topological and dynamical features of social networks: the broad distribution of degree and activities, the average clustering coefficient and the community structure. The theory is born out in three diverse real-world social networks: the network of mentions between Twitter users, the network of co-authorship of the American Physical Society journals, and a mobile-phone-calls network.

Different Tissues

Growth—the progressive change in size and complexity of a person as he moves toward maturity—is often viewed as anatomy's "fourth dimension." It is the "dimension" that provides change: change in size, in proportionality, in morphology, in spatial relationships of structures, in complexity, as well as profound changes in the child's psychological and behavioral framework. As we all appreciate, an adult is not just a very large infant; instead, different tissues and structures have their own agespecific patterns of growth, which accounts for our pretty good ability to determine someone's age simply from their proportions (as in a photograph) without regard to their absolute size.
