Jeff,
I think you chose your subject well. Of course whether wave or quanta we still need to ask 'of what'? but I think you did a very good job. I covered such interactions and the LT in my finalist 2012 & 2013 essays and this year the 3D wave(/particle) dynamic leads logically to rather a shock. Do check it out. I'm interested if you agree my postulates. And the Majorana fermion??
As an Astronomer waves and Lambda are the primary scalar, frequency just the time derivative after arrival/interaction, and Huygens rules. But I didn't see mention of the often ignored Doppler shift found when entering a co-moving medium. Why so?
I'm interested in your electron work and will follow the link you posted to Alan K above. Are you familiar with the Poincare sphere? - 4 orthogonal conjugate states as Maxwells, I've just discovered my experimental discovery already existed! (though ignored). My title; "Ridiculous Simplicity" agreed your conclusion; "The universe is simple and fundamental."
Very best
Peter
