👉 The "Who" in Who Math refers to the mathematical modeling of social networks and interactions, focusing on understanding how individuals or entities (the "who") influence each other within a group. This approach uses mathematical and statistical methods to analyze patterns of relationships, behaviors, and information flow among people. By identifying key actors (nodes) and their connections (edges), Who Math helps predict outcomes, such as the spread of ideas, behaviors, or diseases, and can inform strategies for intervention or optimization in fields like public health, marketing, and social policy.
