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 […]

Definition of activation energy

Activation energy is a concept present in the field of chemical kinetics and other scientific specialties that refers to the minimum amount of energy required to start a process, phenomenon or activity. It is essential that the molecules of a system have a basic level of […]

Definition of infrared radiation

Infrared radiation (IR) is the name given to a type of electromagnetic radiation that is impossible for the human eye to detect. It should be noted that the wavelength of infrared radiation is shorter compared to microwave waves but is longer compared to that associated with visible light. Every body […]

Definition of atomic physics

Atomic physics is the name given to a specialty within physics that has allowed, with the passage of time, to know more and better about the universe. With information provided by this discipline that deals with the atomic structure as a whole, and having mastery of spectroscopy, you can, for example, […]

Definition of synchrotron

Synchrotron is a type of particle accelerator that can be used as a collider. It is a device with multiple applications in which the particles, subjected to the influence of a magnetic field, exhibit a displacement in circular orbit. Its acceleration, the theory says, is the result of an electric field that is […]

Definition of double slit experiment

The double slit experiment is a classic physics experiment that demonstrates the wave-particle duality of light and other particles. It was first made by Thomas Young in 1801, and involves passing light through two narrow slits. By projecting it on a screen behind the slits, […]

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 […]
