- Abstract: We revisit Minkowski's lost legacy on relativistic electromagnetism in order
to resolve long-standing puzzles over the charge distribution of relativistic
systems like hadrons. Hadrons are unique relativistic electromagnetic systems
characterized by their comparable size and Compton wavelength $r_h \sim
\lambda_C$. As such, it was recently realized that the traditional Sachs
definition of the charge distribution based on a non-relativistic formula is
invalid. We explain that this is the same problem pursued by Lorentz, Einstein
and others, on the electromagnetism of a moving body. We show how various
charge distributions proposed in hadronic physics naturally emerge as the
multipole moment densities in the macroscopic theory of relativistic
electromagnetism.

We calculate the next-to-leading order corrections to the neutron's energy spectrum.
While the current precision for observations of ultracold neutrons may not yet enable to probe them, they could still be relevant in the future or in alternative circumstances.

We show that the spacetime dependent phase $f(x)$ is the most natural relativistic extension of the phase associated with the transformation rule for the non-relativistic Schroedinger wave function.
We then generalize the previous analysis by postulating that $Psi(x)$ transforms according to the above rule under proper Lorentz transformations.
