Definition of factor analysis

Factor analysis is a statistical technique used to identify underlying relationships between observed variables. The objective is to reduce their quantity to a smaller number of latent factors that represent underlying constructs, while maintaining as much original information as possible. This method is commonly used in social sciences, psychology and marketing to […]

Definition of collective intelligence

Collective intelligence is the ability that arises from the cooperation of several individuals. It is a concept that is used in different areas, such as sociology and information and communication technologies (ICT). Intelligence is called intellect and the ability to solve problems. It […]

Definition of geothermal

Geothermal energy is, according to the dictionary of the Royal Spanish Academy (RAE), a word with two official meanings. On the one hand, it refers to the grouping of internal phenomena of a thermal nature that occur within the terrestrial globe; On the other hand, it identifies the study carried out by scientists regarding geothermal energy […]

Definition of Maxwell's equations

Maxwell's equations is the name of a set made up of, currently, two pairs of equations that can be formulated either differentially, integrally or according to the propagation of the wave (through a material medium or by the empty). This group, which at some point in the […]

Definition of spacetime curvature

Curvature of space-time is an expression that identifies one of the most relevant derivations of the theory of general relativity that the famous German-born physicist Albert Einstein was able to promote many years ago. As can be seen when analyzing this curvature that involves a mathematical model focused on the unification of space […]

Definition of water quality

Water quality is an expression that aims to describe what characteristics a certain sample or a certain body of water examined possesses. In this analysis process, the safety levels are evaluated when coming into contact, using it for human activities or consuming that liquid, since there are a lot of issues that can […]

Definition of chemical synthesis

Chemical synthesis is an essential procedure for the production of nanoparticles and certain drugs, for example. It is a resource or method that, thanks to the development of chemical compounds based on elemental or simpler substances, allows us to obtain chemical substances that do not exist in nature. To understand what chemical synthesis consists of, […]

Definition of isothermal process

Isothermal process is the name given to the reversible transformation that occurs in a thermodynamic system that presents, throughout said change, a constant temperature. It is easy to identify it compared to other types of processes when it is clear and present that in the dictionary of the Royal Spanish Academy (RAE) […]

Definition of Gay-Lussac law

Gay-Lussac's law is a valid content suitable for ideal gases, while both temperature and pressure are required to be moderate and there is a low gas density to be fulfilled with great precision when dealing with real gases. This postulate that bears the surname of a prominent physicist and chemist of […]

Definition of reaction rate

Reaction rate is a measure of how quickly chemical reactions take place. It is defined as the change in the concentration of reactants or reaction products per unit of time. It can be expressed in terms of the decrease in the concentration of a reactant or the increase […]
