which represents the exergy, that is the “work potential” or “free energy” of E , according to the Second Law of Thermodynamics, and

Comparative understanding of the bibliometrics–thermodynamics consilience in quality and quantity terms up to the definition of
quantity C 2 / P which we noted had energy like properties and from which the p -index was derived. We shall call this the Exergy term, a sort of realizable energy, that modern thermodynamics has introduced (see below).

shortfall, namely S = E − X . Note that unlike conventional thermodynamics, there is no need to define a temperature term, and so entropy here has the same units as energy and exergy. The ratio of exergy to entropy is therefore an indicator for
models of how individual scientists work. It is possible that the relationship between the two approaches is similar to that between statistical physics and thermodynamics, with their microscopic versus empirical descriptions of many body systems, which
