The Heaviside–Feynman formula, also known as the Jefimenko–Feynman formula, can be seen as the point-like electric charge version of Jefimenko's equations. Actually, it can be (non trivially) deduced from them using Dirac functions , or using the Liénard-Wiechert potentials . [ 4 ]
Unlike the two-body problem, the three-body problem has no general closed-form solution, meaning there is no equation that always solves it. [1] When three bodies orbit each other, the resulting dynamical system is chaotic for most initial conditions .
Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
Matrix mechanics is a formulation of quantum mechanics created by Werner Heisenberg, Max Born, and Pascual Jordan in 1925. It was the first conceptually autonomous and logically consistent formulation of quantum mechanics.

In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson , the three generations of quarks and leptons , and the gauge bosons ), including their names, masses, spins, charges, chiralities, and interactions with the strong , weak and electromagnetic forces.
In general, Faddeev equations need as input a potential that describes the interaction between two individual particles. It is also possible to introduce a term in the equation in order to take also three-body forces into account. The Faddeev equations are the most often used non-perturbative formulations of the quantum-mechanical three-body ...
