  Credible reasons are presented to reveal that many of the lingering century
old enigmas, surrounding the behavior of at least an individual quantum
particle, can be comprehended in terms of an objectively real specific wave
function. This wave function is gleaned from the single particle
energy-momentum eigenstate offered by the theory of space filling universal
quantum fields that is an inevitable outcome of Dirac's pioneering masterpiece.
Examples of these well-known enigmas are wave particle duality, the de Broglie
hypothesis, the uncertainty principle, wave function collapse, and predictions
of measurement outcomes in terms of probability instead of certainty. Paul
Dirac successfully incorporated special theory of relativity into quantum
mechanics for the first time. This was accomplished through his ingenious use
of matrices that allowed the equations of motion to maintain the necessary
first order time derivative feature necessary for positive probability density.
The ensuing Dirac equation for the electron led to the recognition of the
mystifying quantized spin and magnetic moment as intrinsic properties in
contrast to earlier ad hoc assumptions. The solution of his relativistic
equation for the hydrogen atom produced results in perfect agreement with
experimental data available at the time. The most far reaching prediction of
the celebrated Dirac equation was the totally unexpected existence of
anti-particles, culminating in the eventual development of the quantum field
theory of the Standard Model that reveals the deepest secrets of the universe
known to date.
