Definition of quantum chromodynamics

Quantum chromodynamics is the name given to a quantum field theory focused on the strong interaction, a fundamental force framed in the standard model of particle physics. As noted when searching for information about the emergence of this type of gauge theory, it is content promoted by David Gross, David […]

Definition of synthetic biology

Synthetic biology is an interdisciplinary discipline built and fed by knowledge, resources and tools from the fields of engineering, computer science and biology. It is based on the redesign of an already existing biological system to add functions or particularities that do not arise naturally. In this framework it is possible to synthesize biomolecules […]

Definition of inflation theory

The inflation theory is a cosmological model that proposes a rapid exponential expansion of the universe during its first moments, immediately after the Big Bang. This cosmic inflation phase would have occurred in a fraction of a second and explains several problems in the standard Big Bang model, such as temperature uniformity […]

Definition of ethics in research

Ethics in research is a concept that refers to the protection of the rights of people and animals involved in investigative work. The notion refers to those principles that contribute to preserving well-being and that allow controlling or minimizing the negative consequences of the knowledge construction process. It fits […]

Definition of Raoult's law

Raoult's Law is the name of a thermodynamic postulate that alludes to the French chemist and physicist who instituted it around 1887: François Marie Raoult. This principle indicates that the vapor pressure (considered at a partial level) of each of the constituents of an ideal mixture based on liquids […]

Definition of chemical potential

The chemical potential is a thermodynamic quantity that describes the capacity of a substance to do chemical work, that is, its tendency to participate in a chemical reaction or to diffuse in a system. It is defined as the change in the free energy of a system when an infinitesimal amount of the substance is added, […]

Definition of collision theory

Collision theory is the name that identifies an old postulate, still valid and useful on a universal scale, which between 1916 and 1918 was promoted by a German chemist named Max Trautz and the British professor and chemist William Cudmore McCullagh Lewis. This content, closely linked to chemical kinetics, […]

Definition of information theory

Information theory is a postulate that explains how data is processed and measured when information is transmitted. Also called mathematical theory of communication, it was developed by biologist Warren Weaver and electrical engineer and mathematician Claude Shannon in the late 1940s. Before moving forward, it is […]

Definition of sampling

Sampling is a procedure carried out to take samples that are considered representative of the average characteristics, quality or conditions of a larger group. The term is also used to name the choice of a small part of a statistical population for the purpose of making an inference […]

Definition of vapor pressure

Vapor pressure is an expression that refers to a phenomenon observed in closed systems at a certain temperature. It consists of a pressure exerted by the gas phase (or vapor) in the liquid phase when the latter and the vapor manage to reach a dynamic equilibrium. When investigating the characteristics, applications and scope of pressure […]
