Its solution was extended from one dimension to two by Lars Onsager, who received the 1968 Nobel Prize in Chemistry.
It was recently shown by Sorin Istrail, who used the method of computational intractability, that this solution could not be extended to three dimensions. Its solution was extended from one dimension to two by Lars Onsager, who received the 1968 Nobel Prize in Chemistry. Its creator conceived of a linear chain composed of particles like little magnets able to take an up or down position, influencing the position of neighboring particles. FTP, identify this model that explains how randomly oriented molecules align themselves in a crystal lattice during phase changes.
