What the Ising model describes — phase transitions in ferromagnets using interacting spins on a lattice

The Ising model explains ferromagnetic phase transitions via spin interactions on a lattice

How does the Percolation Theory model explain the behavior of connected clusters in random graph structures during phase transitions?

Percolation Theory models predict critical thresholds for cluster formation and connectivity in random graphs

What gauge symmetry is — local phase transformations that leave physics invariant, the basis of all fundamental forces
