It was difficult because it was a big change.The transition from classical physics to modern and correct quantum physics was difficult because
Actually it was. That is why you can use Newtonian Physics to land a space craft on the moon and General Relativity for more subtle investigations (such as the precession of the perihelion of Mercury).- the gravity was experimentally not sufficiently correct investigated,
Yes, it was incorrectly assumed that there was an absolute frame.- in the classical physics the precise inertial conditions of the position and of the velocity were assumed,
Of course Maxwell's Equations do.- in the Maxwell equation one does not differentiated between the continuous field Aν (x) and the probability charge and current density jν (x),
As it still is.- and the conservation of energy was assumed as fundamental principle.
That is because particle numbers are not conserved. Mass/Energy is conserved.No theories were developed for particle number conservation and for open physical systems in order to include also the interacting fields which propagate with c.
20th century physics has led to a deeper understanding of the physics of the universe. Your ideas are mere musing based on ignorance, which is fine and I hope your website brings you happiness, but we are not interested in your self-aggrandizing fantasies.The physical revolution at the beginning of the 20th Century has lead only to bad conventions (energy quantization, energy-mass-equivalence relation). Not more!
PS. You keep saying 'bye' and then you come back - that is just cruel.....
