Theories regarding foam formation, structure, and properties—in physics and physical chemistry—differ somewhat between liquid and solid foams in that the former are dynamic (e.g., in their being "continuously deformed"), as a result of gas diffusing between cells, liquid draining from the foam into a bulk liquid, etc. [1]: 1–2 Theories ...
Quantum foam (or spacetime foam, or spacetime bubble) is a theoretical quantum fluctuation of spacetime on very small scales due to quantum mechanics. The theory predicts that at this small scale, particles of matter and antimatter are constantly created and destroyed.
However, the Walrasian general equilibrium theory presents another trend to the synthesis as it attempts to theorise the economy as a whole and is viewed as an alternative to macroeconomics. This approach is considered to be the trigger for exploring microfoundations, [ 1 ] however, the notion of a gap in the "micro-macro" link has been and ...
Continuous foam separation is a chemical process closely related to foam fractionation in which foam is used to separate components of a solution when they differ in surface activity. In any solution, surface active components tend to adsorb to gas-liquid interfaces while surface inactive components stay within the bulk solution.
The earlier term for the discipline was "political economy", but since the late 19th century, it has commonly been called "economics". [22] The term is ultimately derived from Ancient Greek οἰκονομία (oikonomia) which is a term for the "way (nomos) to run a household (oikos)", or in other words the know-how of an οἰκονομικός (oikonomikos), or "household or homestead manager".
The theory of the firm consists of a number of economic theories that explain and predict the nature of the firm, company, or corporation, including its existence, behaviour, structure, and relationship to the market. [1] Firms are key drivers in economics, providing goods and services in return for monetary payments and rewards.
According to one popular kind of macro-economic definition in textbooks, capital formation refers to "the transfer of savings from households and governments to the business sector, resulting in increased output and economic expansion" (see Circular flow of income). The idea here is that individuals and governments save money, and then invest ...
Development economics is a branch of economics that deals with economic aspects of the development process in low- and middle- income countries. Its focus is not only on methods of promoting economic development, economic growth and structural change but also on improving the potential for the mass of the population, for example, through health, education and workplace conditions, whether ...
