Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.
Technology
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .
Economics
How is property given? By restraining liberty; that is, by taking it away so far as necessary for the purpose. How is your house made yours? By debarring every one else from the liberty of entering it without your leave.
Jeremy Bentham, "A Critical Examination of the Declaration of Rights; Article II" in The Works of Jeremy Bentham, Vol. II (1839), p. 503.
Economics
The field of economics is not exempt from the consequences of chaos and complexity. Marketplaces are indeterminate; value is subjective; and outcomes are subject to interpretation. Economic forecasting is just as nebulous, being based on the probability of statistical information that may or may not be accurate.
L.K. Samuels, In Defense of Chaos: The Chaology of Politics, Economics and Human Action, Cobden Press (2013) p. 16.
