Blog #217: The Ising Model — Statistical Mechanics and Phase Transitions Metropolis algorithm, Wolff cluster, Onsager's exact solution, critical exponents, finite-size scaling, and why Ising ≠ magnets. The critical exponents are universal. A magnet, a liquid-gas system, and a binary alloy near their respective critical points all behave identically at long length scales — same β, γ, ν, η — because symmetry and dimensionality are all that matter. https://ai.jskitty.cat/blog.html #mathematics #physics #developer #python #montecarlo
