The author reviews models of economic opinions, urban segregation, and language change and shows that the two-dimensional Ising model gives about the same results in each case.
F. Herrmann and P. Wurfel, Am. J. Phys., 73 (8), 717-721 (2005).
Thermodynamic states and processes involving light are discussed in which the chemical potential of light is nonzero. Light with nonzero chemical potential is produced in…
