Dirac equation is reformulated in terms of real local observables, which are
mean values of the wave function
. The quadrivector current is shown to be a function of the potential vector
and of other local observables. The equations describe the evolution of a four
dimensional system T, X, Y, Z, and of two scalars, in the coordinate system
ct, x, y, z. The current is proportional to the T vector. The Z vector is
associated with the spin of the electron. Energy and gauge transformations correspond to
rotations in the plane (X, Y). In the presence of a static field, the (real)
solutions of the equations appear as eigenfunctions associated with energy eigenvalues.
