Fish Road: A Simple Model of Random Diffusion
Random diffusion is a fundamental process shaping natural systems, where particles, heat, or organisms spread through open environments via chance-driven movement. From microscopic molecules dispersing in air to fish navigating a road network, diffusion underpins countless ecological and physical phenomena. At its core, diffusion follows probabilistic rules—movement occurs randomly, influenced by pathways and distances. The Fish Road model offers a vivid, intuitive illustration of these dynamics, transforming abstract random walks into a navigable grid where every turn and step mirrors...
