Definition of Charles' law

Charles's law is a statement that is responsible for describing how the expansion of a gas is carried out when heated. On the other hand, when the temperature decreases, the volume of the gas decreases. This law indicates that if the pressure applied to a gas sample is constant, the volume and […]

Definition of multiverse

Multiverse is a concept that refers to the set of parallel universes that, according to various hypotheses, coexist alongside ours. Scientists believe that the multiverse contains everything that has physical existence: from all forms of energy, matter and momentum to all time and […]

Definition of weak nuclear force

The weak nuclear force is, as seen when gathering information related to particle physics, one of the fundamental interactions that can be recognized when analyzing the behavior of subatomic particles. The other forces are gravity, the electromagnetic force, and the strong nuclear force. This weak interaction, physics experts point out […]

Definition of Planck constant

Planck's constant is a value of great relevance within quantum mechanics. This is an important discovery made by the German physicist Max Karl Ernst Ludwig Planck; hence the name chosen to identify this physical constant that is expressed by the letter hy that […]

Definition of M theory

M-theory is a proposal initially conceived by an American mathematician and physicist named Edward Witten, who combined the notion of supergravity and superstring theory, identifying eleven dimensions in that framework (a dozen of a spatial nature and the remaining one, a time dimension). It is proposed, from the perspective […]

Definition of space-time

Space-time is a concept that is used in the theories of general and special relativity postulated by Albert Einstein (1879-1955). The notion refers to the integration of space and time into a continuous entity. Space-time can be considered to be a model that establishes an indissoluble link between space and time, […]

Definition of Gibbs free energy

The Gibbs free energy is that which allows the use of a chemical reaction to carry out work at constant pressure and temperature. In other words, it is the energy available so that a thermodynamic system can be realized. This thermodynamic potential makes it possible to predict the spontaneity of a […]

Definition of strong nuclear force

The strong nuclear force is part of the list that accounts for the fundamental interactions that particle physics recognizes within the standard model established to explain what types of forces can occur between subatomic particles. With the weak nuclear force, the electromagnetic force and the force of gravity, the […]

Definition of microwave

Microwaves are electromagnetic waves that can propagate inside metal conduits and through space. Its length ranges from 1 millimeter to 1 meter, with a frequency of between 300 MHz and 300 GHz. Currently, the concept usually refers to the oven that uses this type of waves to […]

Definition of Heisenberg uncertainty principle

The Heisenberg uncertainty principle is a postulate that indicates that it is not possible to know precisely the value of certain pairs of complementary physical variables. The person who enunciated this rule was the German Werner Heisenberg (1901-1976). According to this principle, when the uncertainty about the position occupied by a particle is small, the […]
