Nowadays there are hundreds of book and other resources about quantum mechanics and especially as a beginner it‘s quite hard to decide what is essential and what is fluff. The spectrum ranges from layman books to hardcore-mathematical treatments. The former often have the tendency to strive into mysticism and the latter tend to loose out of sight what physics is all about: describing nature.
Tetryonics 50.08 - Planck mass-energy contributions in elementary Matter & Isotopes provide the excess mass historically attributed to extra Neutrons [in excess of the elements Z number]. These mass-energy contributions provided by Tetryonic theory match Schrodinger's quantum wavenumbers for all elements and offer a new, unprecedented understanding of all the quantum processes in atoms.
