I think I have Feyenman's autobiography. Maybe I should read it! LOL.
I think I mostly grasp what you've said. AT least to have some intellectual construct of it . . .
But the issue of matter waves . . . therefore what?
What can I do in my daily life with an increased knowledge of matter waves?
How can I use an increased understanding of matter waves in practical anticipations regarding ET's and UFO's and even end times?
What practial application of the reality of matter waves can I make now--this week or next year?
Blink your eyelid, or twitch your finger; that's over running matter waves. More extreme : put on a rubber wet suit, well padded, and stand on the sand in front of a seawall when a BIG surf wave SLAMS into it; that's over running matter waves. Or even more extreme : jump off a 10 story building. You don't feel the increasing Particle velocity(+dPv) at 9.8 m/sec^2, the SPLAT you feel at the bottom is OVER RUNNING MATTER WAVES(+dWs).
As to Feynman's 1960's Lectures, your eyes will quickly glaze over with the math; and yet if you hang in there, you'll find incredible nuggets of insight into nature.
For instance : the two basic types of particles, bosons and fermions. With sufficient wit you will understand how LOVE and HATE are rooted in the Bose Inclusion Principle and the Pauli Exclusion Principle. Attraction and Repulsion are as close as playing with 2 magnets...like LOVE/HATE relationships.
Do you remember Jesus saying a soft answer turneth away wrath? The angry person is attracting you to a fight(North magnetic pole facing your South magnetic pole = attraction). Thus the "soft answer" means turning yourself round so that your North pole faces his North pole = repulsion ; he goes away. Or sideways so that the 2 of you go off in separate ways.
This then is the basis for Ghandi's non-violence. There are always young punks who want to "play" by being violent but by shunning them they soon go away to find someone else to "play" with, like the cops, military, courts/judges, officers running prisons.
If you want a current example : fatah vs hamas at each others throats in gaza. Arafat, as satan's tool, taught them HATRED. If they can't kill jews as "play"(fence in the way), then they turn to killing each other.
It's all rooted in QM theory, if they only understood it. Instead they die in their ignorance. I once saw a campaign button : Isn't it such a shame that ignorance isn't PAINFUL?
