I was think about roast beef and the old momentum and time of particle cannot be measured and, as posters here have taught me, cannot be asserted to have any answer whatsoever with regard to the “ultimate” physical description of a particle.
But that thing is still existing. I’ve tried to substitute that process, but that doesn’t help. Thingness is still there.
I “understand” that ultimately (there’s that word again) that no event exists in every and all reference systems, which does call into question, similarly, the “itness” of any thing/process. Ditto, as the night follows the day, sort of, light/wave duality. Does this mean I sort of get the picture, sort of, here (hours and hours of internal and reading discussion not noted here)?
I can feel, intellectually, that my “understanding” of those two is no more or less than what should be the case of my wrapping my head around OP, and is integral to it. Accept two, get the third (the OP). (Einstein got, wrote, the two preceding, but OP is his dice thing?)
I wish I could be like the Queen in Alice, who sometimes believed six impossible things before breakfast. (Not interested here in physics-as-belief system.)
FTR, “NXC” is an abbreviation I created and now bequeath to the Internet, useful for many posts/texts: Not an Existential Crisis
One more thing: I’ve been meaning to ATMB this, and probably will, but posting here on this is, by now for me, like button-holing a few people who I know at a long-running cocktail party. I thank them for this, as well as all posters and readers.
