Understanding some of its properties will not be easy but we can also do it from scratch. There are di erent ways of expressing the Dirac equation. The Dirac Equation and The Lorentz Group Part I – Classical Approach 1 Derivation of the Dirac Equation The basic idea is to use the standard quantum mechanical substitutions p →−i~∇ and E→i~ ∂ ∂t (1) to write a wave equation that is ﬁrst-order in both Eand p. This will give us an 2019-09-10 The Dirac equation in the form originally proposed by Dirac is: where ψ = ψ(x, t) is the wave function for the electron of rest mass m with spacetime coordinates x, t. The p1, p2, p3 are the components of the momentum, understood to be the momentum operator in the Schrödinger equation.
