Fundamentals of Physics (1999)
The gravitational field mechanism was completely quantified in this book, see pages 227-230. We were finally able to derive the equation for mass growth of matter with velocity, see pages 246-7. The energy of matter at rest is, of course. However, we still could not quantify the shrinkage of matter with velocity, nor could we quantify time dilation.
We discovered the mechanism producing the wave property of matter in motion, see pages 265-8. There we derived the de Broglie relation, where p is the particle momentum, is the wave length, and h is Planck’s constant. What happens is that, in order to conserve angular momentum, a photon in captured off-center of the charged particle and the center of mass follows a straight line while the charge field oscillates transverse of the path. (As will he seen later this oscillation produces magnetism.) This chapter also shows how Schroedinger’s equation results from this theory.
