In 1989, Tyler, in his “A Thermodynamics Model of Manpower Systems”, started with the partition function for a thermodynamic system, and via three pages of interesting but funny derivation, produced a table, shown below, listing the "calculated" entropy S, internal energy U, and Helmholtz energy A of what he called “manpower systems” of workers, sized of numbers of individuals N of 0 to 5,000: 
In 1962, Tyler became a senior scientist with the special studies group, at the Institute for Defense Analysis, Washington, D.C. (Ѻ)
