theory of percolation

Percolation theory studies how something spreads or flows through a medium, like how water moves through porous rock or how a fire spreads through a forest. It analyzes the threshold at which enough connections exist for a continuous path, allowing the flow or spread to occur across the entire system. Think of it as understanding how a liquid finds its way through a sponge or how diseases spread through a population, highlighting the critical point where small local connections lead to large-scale connectivity. This helps scientists predict behaviors in physics, ecology, materials, and network systems.
