Definition of observable universe

The observable universe refers to the portion of the universe that we can observe and study from Earth, limited by the speed of light and the time that has passed since the Big Bang. Because light has a finite speed, we can only see objects whose light has had time to arrive […]

Definition of molecular dynamics

Molecular dynamics is the name of a computer simulation technique that is used to observe how particles move. To do this, using a computer, a test of the interaction of molecules and atoms is carried out for a certain period of time. Using numerical procedures, algorithms typical of information theory […]

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, appealing to probability theory, allows us to determine the behaviors both at the microscopic and macroscopic levels of a physical system. With this discipline […]

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 can correspond to a positron or an electron) by […]

Definition of disintegration

Disintegration is the process of separating or decomposing 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 […]

Definition of heat capacity

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

Definition of superposition principle

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 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 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 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 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 […]
