1. A proper relativistic theory with a probability density current must also share this feature. 2. Starting around 1927, Paul Dirac combined quantum mechanics with the relativistic theory of electromagnetism. 3. One of these involved analyzing the physics of a twirling, relativistic theory of electrons. 4. In relativistic theories , there is both a particle and field representation for every theory. 5. In some sense, the relativistic theories . 6. The more relativistic theories of Einstein and Heisenberg mirror our own relativism _ and our restlessness. 7. In 2004, Jacob Bekenstein formulated TeVeS, the first complete relativistic theory with MONDian behaviour. 8. Some features of Lagrangian mechanics are retained in the relativistic theories but difficulties quickly appear in other respects. 9. The second pillar of QED consists of the relativistic theory of the electron, centered on the Dirac equation. 10. Unlike the nonrelativistic case, it is impossible to produce a relativistic theory of local particle propagation without including antiparticles.
