Definition of neutron stars

Neutron stars are, according to scientists specialized in astronomical matters, a type of stellar remnant that emerged as a result of the gravitational collapse of massive supergiant stars. This phenomenon is triggered once they exhausted the fuel present in their cores and exploded like a supernova in one of their […]

Definition of photoelectric effect

Photoelectric effect is a concept that was consolidated from a discovery made in 1887 by a German physicist named Heinrich Rudolf Hertz. This expert warned that when ultraviolet light shines on a charged element, it tends to easily lose its charge. His observation showed that, with said lighting, the […]

Definition of antiparticle

Antiparticle is a notion typical of the field of particle physics that is used to describe that particle of an elementary nature that has identical spin and mass but an opposite electric charge with respect to the particle that corresponds to it. Thus, when both are united within the framework of an appropriate quantum state they end […]

Definition of Ohm's law

Ohm's Law is the name that identifies a key postulate to understand the fundamentals of an electrical circuit. Included in this name is the surname of Georg Simon Ohm, the mathematician and physicist of German origin whose identity has also been exalted by choosing how to name the ohm (unit of resistance). According to […]

Definition of electrical conductivity

Electrical conductivity is an expression specific to the field of Physics that refers to a property or capacity of a substance or material to conduct electricity by allowing an electric current to pass through it. Temperature and both molecular and atomic structure are some determining issues for electrical conductivity to be possible. […]

Definition of energy conversion

Energy conversion is the process by which one form of energy is transformed into another. This includes, for example, converting chemical energy into thermal energy through combustion, or converting solar energy into electrical energy using solar panels. This process is fundamental in various technological systems and devices to carry out […]

Definition of spin

Espín is a term with several interpretations in the Spanish language. While today it is very useful within quantum mechanics and particle physics, in other times it served in the military field to identify the order in which a squad was organized to confront the enemy from all […]

Definition of cosmic radiation

Cosmic radiation is a highly energetic form of radiation that comes from outer space. These are cosmic rays composed mainly of protons, helium nuclei and other subatomic particles. They originate from various cosmic sources, such as supernovae, black holes, and other extreme astrophysical events. Upon reaching Earth, they interact with the atmosphere, […]

Definition of Bohr atomic model

The Bohr atomic model is a presentation focused on atoms made in 1913 by a prominent Danish physicist named Niels Bohr. This contribution was motivated by the intention, taking Rutherford's atomic model as a starting point, to provide an explanation in relation to how matter achieves stability. Bohr […]

Biography of Galileo Galilei

Galileo Galilei is the identity of a multifaceted man born in Italy who, for his valuable discoveries and achievements, is recognized universally as "the father" or main exponent of modern science. His arrival into the world, according to records, occurred on February 15, 1564 in Pisa, while […]
