Definition of superposition principle

Superposition principle is the name of a tool that offers the possibility of breaking down a certain problem into a pair, or more, of structures of lower complexity. This resource, also known as the superposition theorem, is partially valid and appropriate whenever there are linear functions, linked to mathematical problems, […]

Definition of Uranus

Uranus is the seventh planet in the solar system, located about 2.9 billion kilometers from the Sun. It is an ice giant, composed mainly of hydrogen, helium and compounds such as water, ammonia and methane. Uranus is known for its blue-green hue, a result of methane in its atmosphere absorbing red light. TO […]

Definition of environmental monitoring

Environmental monitoring is a practice that is implemented in a specific place for a certain time in order to evaluate and monitor the state and conditions that the environment presents at that moment. Just as today there are methods that facilitate this task and technological advances that greatly benefit it, […]

Definition of microwave background radiation

Microwave background radiation is a classification that identifies a type of electromagnetic radiation that was discovered in 1965. It is noted as one of the most conclusive evidence supporting the Big Bang. The existence of what is also called cosmic background radiation or cosmic microwave radiation was confirmed after […]

Definition of fuel cells

Fuel cells are electrochemistry-based devices that generate electricity through a chemical reaction, usually between hydrogen and oxygen, without combustion. In a fuel cell, hydrogen is oxidized at the anode and oxygen is reduced at the cathode, producing water, heat and electricity as byproducts. This […]

Definition of anisotropy

Anisotropy is a term that the Royal Spanish Academy (RAE) presents in its dictionary as a word from the field of physics that refers to the condition of anisotropic. This word, in turn, refers to the diversity of physical properties that a body or substance can demonstrate according to […]

Definition of Krebs cycle

Krebs cycle is one of the names given to a series of chemical reactions that occur in aerobic organisms as part of the cellular respiration process. In eukaryotic cells, what is also known as the tricarboxylic acid cycle or citric acid cycle takes place in the mitochondrial matrix (an area or […]

Definition of classical mechanics

Classical mechanics is the name that has become popular to distinguish a branch of physics whose focus is on precisely evaluating how macroscopic-level physical bodies behave, both at rest and at a certain speed. In this area of ​​study that connects movement with force and acceleration […]

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 […]
