It is possible to seamlessly integrate relativity into quantum mechanics starting
with some very elementary arguments about electromagnetic fields. Getting to those
argument took a number of years of experimental work in the areas of hydrogen
diffusion in iron and other metals, dynamic ferromagnetic losses in iron and steel,
terrestrial magnetism, and superconducting losses in niobium SRF accelerator
modules. The experimental work essentially was at the extremely low end of the
energy range considering the behavior of particles with masses of 10−9 to 10−22
electron masses. These very light creatures are inherently relativistic at almost
any energy above the rest energy and in one case their behavior can be monitored in
detail. A new quantum state equation was derived in its own reference frame which
automatically generates the two families of particles and defines their property
behavior in the laboratory frame. The results are not only useful for extremely low
mass particles but is also quite useful for nuclear matter in the ground state. Some
new applications to nuclear physics will be presented. A complete description is 
contained in our new book ”The Principles of Matter: Reworking Relativistic Quantum Mechanics”
