Explore complex systems through the lens of statistical physics in this engaging 39-minute conference talk from the Santa Fe Institute's Annual Science Board Symposium. Join Sidney Redner as he delves into random walks, data analysis, and lead changes in various contexts, including sports. Discover how statistical physics concepts can be applied to understand the dynamics of lead changes, first passage paths, and the concept of a "safe lead." Compare theoretical predictions with real-world data and gain insights into the fascinating intersection of statistical physics and complex systems analysis.
