In science, economics is the study of they wealth as what is produced by humans in order to maintain their existences. [1]

Overview
The term "economics" means “household management and agriculture”, deriving from the title of a 362BC book by that name by Xenophon, student of Socrates, becoming in 1792 synonymous with the “science of wealth”, some of which molded historically into the physiocracy ideas of Francois Quesnay.

The founders of "classical economics", according to Wassily Leontief (1982), are: Adam Smith, David Ricardo, Thomas Malthus, and John Mill.

The founders of "neoclassical economics" are: Leon Walrus and Vilfredo Pareto and their "general equilibrium theory", which, in the 1980s, according to Leontief, constituted the "core of undergraduate and graduate instruction" in America. [3]

Thermodynamics
The study of economics, in thermodynamics, is called "economic thermodynamics" or in some cases thermoeconomics.

“Laplace is reputed to have said: ‘give me the equations of motion and I will show you the future of the universe’. Likewise, economists studying the evolution of a large general equilibrium system ask only for the equation of motion in order to bring their work to completion.”
