Definition of molecular dynamics

Molecular dynamics is the name of a computer simulation technique used to observe how particles move. To do this, a computer tests the interaction of molecules and atoms over a certain period of time. Using numerical procedures, algorithms from information theory and other methods, the experiment is carried out.

Definition of statistical mechanics

Statistical mechanics is the name given to one of the branches that expands the scope and specializations of physics. It is an area of ​​study that, by appealing to the theory of probability, allows determining the behaviors of a physical system at both the microscopic and macroscopic levels. With this discipline, we can study the behavior of a system […]

Definition of beta decay

Beta decay is the name given to a process that is interpreted as a derivation of the weak interaction and is linked to the atomic nucleus. This phenomenon, in which the mass number remains stable, involves the emission of a beta particle (which may correspond to a positron or an electron) by a particle that is released into the atmosphere.

Definition of disintegration

Decay is the process of separation or decomposition of a whole into smaller parts or simpler elements. It is a concept that suggests a process of deterioration or loss of cohesion in a system that was previously united or functioned as a unit. Decay in Physics In Physics, there is radioactive decay, a process of […]

Definition of heat capacity

Heat capacity is an expression that identifies the result of dividing the heat transfer that, regardless of the process taking place, reaches a system or body and the temperature variation experienced by it. Expressed in another way, also known as thermal capacity, refers to the energy required to cause, […]

Definition of principle of superposition

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

Definition of microwave background radiation

Cosmic microwave background radiation is a classification that identifies a type of electromagnetic radiation that was discovered in 1965. It is considered one of the most conclusive proofs supporting the Big Bang. The existence of the so-called cosmic microwave background radiation or cosmic microwave radiation was confirmed after the discovery of […]

Definition of anisotropy

Anisotropy is a term that the Royal Spanish Academy (RAE) presents in its dictionary as a word specific to 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 show according to its properties.

Definition of classical mechanics

Classical mechanics is the name that has become popular to distinguish a branch of physics that focuses on accurately evaluating how macroscopic physical bodies behave, both at rest and at a certain speed. In this area of ​​study that connects motion with force and acceleration, we can see that the mechanics of a body are […]

Definition of Maxwell's equations

Maxwell’s equations is the name of a set of equations that currently consist of two pairs of equations that can be formulated either differentially, integrally or according to the propagation of the wave (through a material medium or through a vacuum). This group, which at some point in the history of physics, is a set of equations that can be formulated in a differential manner, integrally or according to the propagation of the wave (through a material medium or through a vacuum).
