THERMODYNAMICS		ECONOMICS
U = internal energy	…	G = growth potential
T = temperature	…	I = internal politics stability
S = entropy	…	E = entropy
P = pressure	…	P = price level (inflation)
V = volume	…	Q = volume, structure, quality
M = total energy (mass)	…	Y = national income (income)
Q = electric charge	…	$\mathcal{I}$ = total investment
J = angular momentum	…	J = economical investment angular momentum
(spin)		(investment spin)
M = M(S,Q,J)	…	Y = Y(E,$\mathcal{I}$,J)
$\mathsf{\Omega }=\frac{\partial M}{\partial J}$ = angular speed	…	$\frac{\partial Y}{\partial J}$ = marginal inclination to investment turnover
$\mathsf{\Phi }=\frac{\partial M}{\partial Q}$ = electric potential	…	$\frac{\partial Y}{\partial \mathcal{I}}$ = marginal inclination to investment
$T_H=\frac{\partial M}{\partial S}$ =Hawking temperature	…	$\frac{\partial Y}{\partial E}$ = marginal inclination to entropy
${\mu }_k$ = chemical potentials	…	${\nu }_k$ = economical potentials
