Dirac then suggested a more general formulation of quantum mechanics which deals with abstract objects such as kets (state vec-tors), bras, and operators. The representation of Dirac’s formalism in a continuous basis—the position or momentum representations—gives back Schrödinger’s wave mechanics. As for
Dirac and later quantum physicists managed to reconcile quantum mechanics with Einstein’s special relativity – eventually giving us the foundations of elementary particle physics, quantum field theory. But no one has yet been able to quantise gravity in a grand unified theory.
By complete I mean we have derived expressions for the Bohm energy-momentum, the Dirac quantum potential energy, and the evolution of the components of the spin of a Dirac particle.
