The Dirac equation, like the Klein–Gordon equation, possesses solutions with negative energy, which, in the framework of wave mechanics, leads to difficulties (see below). To prevent transitions of an electron into lower lying states of negative en-ergy, in 19306 Dirac postulated that the states of negative energy should all be occupied.

Dirac’s equation is a relativistic wave equation which explained that for all half-spin electrons and quarks are parity inversion (sign inversion of spatial coordinates) is symmetrical. The equation was first explained in the year 1928 by P. A. M. Dirac. The equation is used to predict the existence of antiparticles. Dirac synonyms, Dirac pronunciation, are usually presented as objects that undergo a transformation during a Lorentz transformation of the Dirac [6.7] equation. The Dirac equation, like the Klein–Gordon equation, possesses solutions with negative energy, which, in the framework of wave mechanics, leads to difficulties (see below). To prevent transitions of an electron into lower lying states of negative en-ergy, in 19306 Dirac postulated that the states of negative energy should all be occupied.

As a result, Dirac's equation describes how particles like electrons behave when they travel close to the speed of light. "It was the first step towards what's called quantum field theory, which
Also we would like to have a consistent description of the spin of the electron that in the non-relativistic theory has to be added by hand. 1.
equation, in which only the first time derivative of the wave function appears. In his book “The Principles of Quantum Mechanics” Dirac wrote that “we deduced from quite general arguments that the wave equation must be linear in the operator ∂/∂t”, and that an equation of motion
It attempted to solve the problems with the Klein-Gordon Equation. In Quantum Field Theory, it is the field equation for the spin-1/2 fields, also known as Dirac Fields.

Dirac's equation also contributed to explaining the origin of quantum spin as a relativistic phenomenon. Even among sometimes eccentric theoretical physicists

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 component equation.
Since its first formulation, its meaning has changed from a relativistic wave equation for an electron to a classical field equation from which an electron-positron quantum field Also, the Dirac equation for the electron implied that it should have spin 1/2, and a magnetic moment of eh/(4 p m), where h is the Planck constant and m is the electron mass, correct to the accuracy of 0.1%. Dirac’s equation and his theory of the electron have remained firm up to the present day. The Dirac equation.
