Definition of time dilation

Time dilation is a phenomenon predicted by Einstein's theory of relativity, in which time passes more slowly for an object in motion relative to an observer at rest. This occurs because, at speeds close to that of light, time stretches or dilates, […]

Definition of pattern recognition

Pattern recognition is the name that identifies a discipline specialized in processes typical of the fields of mathematics, engineering, computing and even psychology that are related to either abstract or physical objects (texts, sounds, images, etc.). ). This area of ​​study, which is also often referred to as recognition of […]

Definition of quantum cryptography

Quantum cryptography is a concept that identifies a discipline in which guidelines from quantum mechanics are used in order to guarantee confidential and secure transmission of information. Before focusing on the characteristics, applications and limitations of this type of practice sometimes referred to as encryption […]

Definition of water footprint

Water footprint is the name of an environmental indicator that shows how much (volume) of fresh water a producer uses when carrying out the development of a service or consumer good. Beyond reporting how much of this resource is used within the framework of a process […]

Definition of anthropic principle

Anthropic principle is an expression that encompasses an idea whose content can be approached or analyzed from cosmology and physics, as well as from theology and philosophy. This concept that gained relevance after being pronounced in a symposium by an expert in theoretical physics who was born in […]

Definition of cell differentiation

Cell differentiation is the process by which an immature or undifferentiated cell specializes to perform specific functions within an organism. The cells acquire particular morphological and functional characteristics, differentiating into cell types such as neurons, muscle or blood cells. Importance of cell differentiation Cell differentiation is essential for the development […]

Definition of Schrödinger's cat

Schrödinger's cat is the name given to a thought experiment that Erwin Schrödinger devised in 1935. It should be noted that this philosopher and physicist of Austrian origin who obtained Irish nationality, in addition to making valuable contributions in the field of thermodynamics and quantum mechanics, managed to leave an indelible mark […]

Definition of tunneling effect

The tunneling effect is a quantum phenomenon in which a particle can cross an energy barrier that, according to the laws of classical physics, it should not be able to overcome. This effect occurs due to the probabilistic nature of subatomic particles in quantum mechanics. A well-known example is that of the […]

Definition of holography

Holography is a term that refers to a photography technique aimed at obtaining three-dimensional color content from a laser lighting process, as well as the image that results from the application of said method. It is also common to resort to the concept of hologram to […]

Definition of Casimir effect

Casimir effect is the name of a force of attractive power that is associated with a derivation of the quantum vacuum. This measurable essence effect that was anticipated by quantum field theory is also known as the Casimir-Polder force. These names allude to both Hendrik Casimir and Dirk Polder, two physicists […]
