Although the law was known earlier, it was first published in 1785 by French physicist Charles-Augustin de Coulomb. Coulomb's law was essential to the development of the theory of electromagnetism and maybe even its starting point, [1] as it allowed meaningful discussions of the amount of electric charge in a particle.

Coulomb made groundbreaking contributions to the understanding of earth pressure, which have become foundational in geotechnical engineering. In 1776, he presented Essai sur une application des règles de Maximis et Minimis à quelques Problèmes de Statique, relatifs à l’Architecture, to the Académie des Sciences. [14]
The Coulomb gauge (also known as the transverse gauge) is used in quantum chemistry and condensed matter physics and is defined by the gauge condition (more precisely, gauge fixing condition) (,) =. It is particularly useful for "semi-classical" calculations in quantum mechanics, in which the vector potential is quantized but the Coulomb ...
In statistical physics, a Coulomb gas is a many-body system of charged particles interacting under the electrostatic force. It is named after Charles-Augustin de Coulomb, as the force by which the particles interact is also known as the Coulomb force. The system can be defined in any number of dimensions.
The understanding of friction was further developed by Charles-Augustin de Coulomb (1785). [22] Coulomb investigated the influence of four main factors on friction: the nature of the materials in contact and their surface coatings; the extent of the surface area; the normal pressure (or load); and the length of time that the surfaces remained ...
The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton (+1 e) or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.
Coulomb energy, the potential energy from each pair of protons. As this is a repelling force, the binding energy is reduced. Asymmetry energy (also called Pauli energy), which accounts for the Pauli exclusion principle. Unequal numbers of neutrons and protons imply filling higher energy levels for one type of particle, while leaving lower ...
The Coulomb operator, named after Charles-Augustin de Coulomb, is a quantum mechanical operator used in the field of quantum chemistry. Specifically, it is a term found in the Fock operator . It is defined as: [ 1 ]
