The Dirac equation is the relativistic description of an electron. The non-relativistic description of an electron is described by the Pauli-Schroedinger equation. The non-relativistic electron has two spin states and we say that it is a two com

It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress.

From the classical equation of motion for a given object, expressed in terms of energy E and momentum p, the corresponding wave equation of quantum mechanics is given by making the replacements equation. In his first attempts towards a relativistic theory, Dirac consider a Klein-Gordon type equation written in terms of a relativistic Hamiltonian:12, . Upon reading Dirac’s articles using this equation, Ehrenfest asked Dirac in a letter on the motive for using a particular form for the Hamiltonian: In quantum field theory, the nonlinear Dirac equation is a model of self-interacting Dirac fermions. This model is widely considered in quantum physics as a toy model of self-interacting electrons. The nonlinear Dirac equation appears in the Einstein-Cartan-Sciama-Kibble theory of gravity, which extends general relativity to matter with intrinsic angular momentum. This theory removes a constraint of the symmetry of the affine connection and treats its antisymmetric part, the Unlike the KG equation, the Dirac equation has probability densities which are always positive.

Completely unrelated, and yet strangely parallel. For one thing, they're both mysterious — we don’t really understand how either one of them works. So Dirac had, courtesy of his equation, been the first to glimpse what was once nearly half the material universe, about which the rest of humanity had no inkling until he let them in on the secret.

It is consistent with both the principles of quantum mechanics and the theory of special relativity, and was the first theory to account fully for special relativity in the context of quantum mechanics. It was How Paul Dirac, a brilliant but lonely man, found something new and wonderful that had been missing his entire life: love. The life-changing love of one of the 20th century’s greatest physicists An essay by Dr. Frank Wilczek, a physics professor at the Massachusetts Institute of Technology, recounts how the 25-year-old Dirac published an equation in 1928 purporting to describe the single meaning, like the Dirac equation, because no such distillation could represent love. Any attempt at such a distillation would undermine the authenticity of readers' reactions, destroying the delicate, participatory creative experience of a good reader reading a The Dirac equation introduces four components (each with their own partial differential equation) to the wave.

See the figure, We have the Dirac equation with the slash notation: ( γ μ p μ − m) ψ =0. In the presence of an electromagnetic field, we get: ( γ μ ( p μ − e A μ) − m) ψ =0.
