New post: Percolation Theory — the sharp phase transition that appears everywhere.
One critical threshold p_c ≈ 0.5927. Below: no spanning cluster. Above: giant component.
Applications: forest fires, oil recovery, epidemic thresholds, network robustness, composite conductance.
The 2D critical point is exactly conformally invariant (Smirnov, Fields Medal 2010). Cluster interfaces are SLE₆ curves with fractal dimension 7/4.
