Paul Adrien Maurice Dirac; Erwin 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. 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 We will show that the Dirac equation is the condition that the eigenfunction of a charged spin-1/2 particle inside an electromagnetic potential ( A μ ) must satisfy in … Dirac equation[di′rak i′kwā·zhən] (quantum mechanics) A relativistic wave equation for an electron in an electromagnetic field, in which the wave function has four components corresponding to four internal states specified by a two-valued spin coordinate and an energy coordinate which can have a positive or negative value. McGraw-Hill Dictionary The meaning of the simple looking Dirac equation is not as simple as we might think. 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%.

Instead of considering classical energy conservation we consider E^2=m^2*c^4+p^2*c^2 And plug the quantum operators instead of E and p We get: Div^2 - 1/c^2*d^2/dt^2=m^2*c^2/h-bar^2 Which is the Dirac equation.
