By comparing people to mobile particles randomly bouncing off each other, scientists have developed a new model for social networks. The model fits with empirical data to naturally reproduce the community structure, clustering and evolution of general acquaintances and even sexual contacts.
In this visualization of a high school’s empirical friendship network from the scientists’ data, the different colored (blue, green, purple, orange) nodes represent students in different grades. Links between nodes are drawn when a student nominates another student as a friend. In the recent study, physicists developed a novel model to describe this social network based on rules governing physical systems. Credit: Marta Gonzalez Read more at www.physorg.com/news116...
