Definition of electromagnetic radiation

Electromagnetic radiation is a form of energy that spreads through space in the form of electromagnetic waves. Each electromagnetic wave is composed of more than one electric field and magnetic field that oscillate perpendicular to each other and in the direction of wave propagation. Electromagnetic radiation covers a wide range of frequencies, […]

Definition of black hole

A black hole is an area of ​​space with highly dense matter. Due to this enormous condensation of matter, it has a great force of gravity and produces a distortion in space-time. It should be considered that black holes are not holes nor are they empty: on the contrary, they contain more matter in less […]

Definition of chaos theory

Chaos theory is a concept that is used in various sciences to refer to the changes that occur in a system when a variation in its initial conditions is recorded. These modifications can be very important even when the first alteration is minimal. In deterministic systems, it is understood that the behavior […]

Definition of Higgs boson

The Higgs boson is an elementary particle whose name pays tribute to the English physicist Peter Higgs. This scientist alluded to a possible mechanism as an explanation for the emergence of the mass of particles of this type. A fundamental or elementary particle that establishes interactions between fermions is called a boson. The particles […]

Definition of electrical network

The electrical grid is the infrastructure that makes it possible for electricity to reach the supplier to the user. Thanks to its various components, electrical energy can be transported from the place where it is generated to the point of consumption. It should be considered that a network is a set of elements that are organized in a certain way […]

Definition of energy levels

Energy levels come into play and become visible in multiple contexts. In the field of health, for example, this idea is related to the strength or vitality that can be gained or lost depending on someone's age, lifestyle or habits. Not having a balanced diet […]

Definition of fundamental forces

Fundamental forces are, according to particle physics experts, interactions produced in the universe that cannot be broken down into more basic processes or phenomena. This set encompasses a standard model made up, in principle, of four elements: the weak nuclear force, the strong nuclear force, the force of gravity and […]

Definition of cogeneration

Cogeneration is the process that allows the simultaneous production of electrical and/or mechanical energy together with useful thermal energy. In this way, the generation of heat and electricity (CHP) can be achieved from a primary source. Typically, a cogeneration plant is made up of turbines and reciprocating engines that make it possible […]

Definition of Van der Waals forces

Van der Waals forces are interactions between molecules, as studied in the field of physical chemistry. This class of intermolecular forces are characterized by presenting anisotropy (a condition that indicates that their properties depend on the orientation of the molecules) and were named after a prominent physicist and professor of […]

Definition of doppler effect

The Doppler effect is the phenomenon that occurs when the frequency of a wave that is perceived registers a change because the source or the receiver itself is in motion. The name pays tribute to the Austrian physicist and mathematician Christian Andreas Doppler (1803-1853), who discovered this reality. It is important to indicate that […]
