Social physics is a new social science that uses mathematical methods to study the influence of information flow on human behavior. A sophisticated technique for studying the “breadcrumbs” that we leave behind on the Internet makes it possible to predict the behavior of social groups, the productivity of new companies, guide the development of individual urban areas and even entire cities, generate beneficial feedback on social networks, and generally make society better. . The author of the book is a professor at the Massachusetts Institute of Technology, one of the most respected experts in the field of big data and new technologies.
