U = internal energy	…	G = growth potential
T = temperature	…	I = internal political 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 = economic angular momentum
(spin)		(economic spin)
M = M(S,Q,J)	…	Y = Y(E,$\mathcal{I}$,J)
${\mu }_k$ = chemical potential	…	${\nu }_k$ = economical potential
$N_k$ = number of moles	…	${\mathcal{N}}_k$ = number of economic moles
W = mechanical work	…	W = wealth of the system
Q = heat	…	q = stock market
$T_H=\frac{\partial M}{\partial S}$ = Hawking temperature	…	$I_{BH}$ = BH-internal political stability
G = Newton constant	…	$\mathcal{G}$ = universal economic constant
c = light velocity	…	c = maximum universal exchange speed
