The Dirac equation: spin, Zitterbewegung, the Compton wavelength,
and the foundation of the electron mass

The Dirac equation, which was derived by combining, in a consistent manner, the relativistic invariance condition and the quantum superposition principle, has shown its fecundity by explaining the spin, predicting antimatter, and providing a consistent picture of Schrödinger's trembling motion. It has also generated two paradoxes: one is the expectation value of the electron velocity; and the other is the half-integer value of the electron spin (which has shown agreement with all observations, including magnetism). In this paper, we discuss these paradoxes in relation with the structure and mass of the electron.
