Quantum dynamics

* I might be happier, if I could understand the interactions among elemental particles and between such particles and space associated with emission and absorption of photons.  I wonder:
* Why don’t an atom’s electrons fall into its nucleus?  What geometric or mechanical change of an atom’s electron is associated with emission or absorption of a photon?  Is it a change in orbital radius or could it be a change in orbital vibration?
* Reading between the lines, I suspect that every photon has the same composition (a common number of wave cycles, 1 or n, or 1 pulse) and that the wave or pulse of every photon has the same amplitude.  Accordingly, a photon of twice the energy has twice the frequency and half the length -- or something like that.
 * Photons are not quantized, except by virtue of their emission and absorption dynamics, unless we can believe inflationary and relativistic red shifts to be quantized.
* It should be fun to imagine the composition and dynamics of antenna-emitted radio waves, these being generated from innumerable jerky electrons being accelerated phasically in opposite directions.  The photon conglomerate presumably disperses during inverse-square spreading.  Would such photons have odd shapes?  Since they induce corresponding oscillations in receiving antennae, they must retain information about the direction of electrons that produced them.  A corollary is that photons are pulses, not waves. A wave shouldn't retain such directional information.
 * The microwave background consists of very-low-frequency photons.  I recon that the microwaves of a radar or oven are not photons but are conglomerates of higher-frequency photons, perhaps longer IR photons, which cooperate in driving electrons in a target antenna or food alternately in opposite directions at microwave frequency.  The retention of directional information is easier explained if photons are pulses, not waves.
* The finding that electrons (having electric and magnetic fields) interfere in the double-slit experiment may not prove that particles per se have wave character.  However, a similar result with neutrons seems convincing, though mysterious.  Could it be that the fields of opposite charges in a neutron do not cancel but extend side by side throughout space?
 * How can I reconcile my deterministic convictions with probabilistic particle behavior?
 * What data support detailed electron orbital models?
