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 […]

Definition of nuclear physics

Nuclear physics is the name given to one of the branches of physics. It is a discipline that focuses on the interactions, properties and behavior of the atomic nucleus. The history of nuclear physics began to be written and take on its own momentum when the French physicist Henri […]

Definition of lepton

A lepton is a fermion that can be neutral or have an electric charge and is not affected by the strong interaction. It is an elementary particle because its decomposition into others of greater simplicity is not possible. It should be noted that strong interaction is one of the fundamental forces recognized in the […]

Definition of critical mass

The concept of critical mass can be defined in the following contexts: Nuclear physics: Critical mass is the minimum amount of fissile material necessary to maintain a self-sustaining nuclear chain reaction. In simple terms, it is the minimum amount of uranium-235 or plutonium-239, for example, that is needed for a nuclear reaction to […]

Definition of Pauli exclusion principle

Pauli exclusion principle is the name given to content linked to the field of quantum mechanics. The name of this expression refers to the surname of a theoretical physicist of Austrian origin since it was he, a man named Wolfgang Pauli who obtained Swiss and American citizenship, who in 1925 […]

Definition of quantum computing

Quantum computing is a computing paradigm that is based on quantum entanglement and the superposition of matter. This implies a much greater processing capacity than that offered by traditional or classical computing. While conventional computing allows the representation of information in a binary manner and each […]

Definition of cosmic rays

Cosmic rays are subparticles (or subatomic particles) that come from space and have the peculiarity of being as fast as they are full of energy. Trying to establish the origin of cosmic radiation and reveal various mysteries around this topic has led scientists to investigate for many decades how they are born, […]

Definition of particle accelerator

Particle accelerator is the name given to a highly complex device that, by using electromagnetic fields, accelerates charged particles to high speed with the intention of causing a collision of particles. In this context, an enormous number of new particles emerge, characterized by their brevity and instability. In a way, these teams […]

Definition of Zeeman effect

The Zeeman effect is a physical phenomenon that consists of the splitting of spectral lines into several components in the presence of a magnetic field. It was discovered by the Dutch physicist Pieter Zeeman in 1896 and can be explained by the interaction of the magnetic field with the magnetic moment associated with the electrons of atoms. […]
