 One issue concerning quantum mechanics has always bothered me. Why was is a wave model assumed for quantum events? Is this solely in attempt to match experimental observation? Wave mechanics is still classical in foundation quantum happenings seem to be in a completely scheme than classical events, which is the source of my discontent. Have other models been successfully applied to quantum mechanics?  One issue concerning quantum mechanics has always bothered me. Why was is a wave model assumed for quantum events?

 It is my understanding that the wave model was derived and created before very much experimental observation had been made at all (at least on small scales...  we've still not got very good small scale observational skills, instruments limited as they are) .  But I believe this is born in part from Planck's discovery of light quanta and Einstein's wave-particle duality description of light.  As well as an attempt at explaining the behavior of electrons staying in orbital -- so inherently there was a need for quantized energy levels.   It is my understanding that the wave model was derived and created before very much experimental observation had been made at all (at least on small scales...  we've still not got very good small scale observational skills, instruments limited as they are) .  But I believe this is born in part from Planck's discovery of light quanta and Einstein's wave-particle duality description of light.  As well as an attempt at explaining the behavior of electrons staying in orbital -- so inherently there was a need for quantized energy levels.

 I think you should come up with a new model.  Something Einstein would like better! I think you should come up with a new model.  Something Einstein would like better!

 This question is similar to the one I posed earlier and I would still like to ask it. If we could find the emission time of a photon with greater precision, would that narrow its probability function? (For all time, because its probability function does not change over time?) This question is similar to the one I posed earlier and I would still like to ask it.

 What exactly is a stationary state? They talk a little bit about it on page 26 of Griffiths...Is it just every solution of the time independent solution to the Sch. Eqn.? What exactly is a stationary state? They talk a little bit about it on page 26 of Griffiths...Is it just every solution of the time independent solution to the Sch. Eqn.?

 A stationary state is synonymous with Eigen state.  Basically, a state that doesn't radiate energy. The probability density of these states has no time dependence. Small perturbations can be ignored.  Hence... stationary... in time.  It should be noted that the only true stationary state is the ground state.  With enough perturbation ... a stationary state can be made un-stationary. yes? Like granny in her rocker.  Small movement doesn't tip her out... but come hurricane season... she's not really stationary till she's on the ground.   A stationary state is synonymous with Eigen state.  Basically, a state that doesn't radiate energy.
