Electron spin plot exhibiting a disordered phase of the 2D Ising model.

Barry Simon: "This model was suggested to Ising by his thesis adviser, Lenz. Ising solved the one-dimensional model...and on the basis of the fact that the one-dimensional model had no phase transition, he asserted that there was no phase transition in any dimension. As we shall see, this is false. It is ironic that on the basis of an elementary calculation and erroneous conclusion, Ising’s name has become among the most commonly mentioned in the theoretical physics literature. But history has had its revenge. Ising’s name, which is correctly pronounced "E-zing", is almost universally mispronounced "I-zing".
