Particles do not retain "information", don't have "knowledge". It is not that the act of observation that alters reality. In fact the physical nature of the "observation" small though it may be is sufficient to alter the metrics of sub atomic particles.

I believe Bell proved there is no hidden variable theory that matches quantum predictions.
My takeaway has always been that the world is a lot weirder than we want.
Correct.
I have Bell’s “Speakable and Unspeakable in Quantum Mechanics” and surprisingly, actually understand alot of it!
He was a brilliant guy. To find the things he did and not lose his mind in the process must have been quite a challenge!
And, of course, the Aspect experiments proving most of his predictions.
You would have to be brilliant and very well educated to actually work with these kinds of things. I however am just an average Joe that finds all these mysteries really fascinating, and have read a lot about it over the years, but I actually understand very little. I keep saying to myself, “how can it be that way?”
Quantum mechanics just says that what is knowable, is probabilities; and that certainty (or near certainty) in one atomic/quantum (small) observation makes for much uncertainty in another.
Many of the issues that people have with quantum mechanics have their roots in the thought experiment explanations. Action on a small scale defies being described in terms that reflect our ability to intuit. "Wave / Particle duality" being one such thought experiment, Schroedinger's cat being another.
It wouldn’t matter to the ball if I was there to intercept photons that already contacted the ball.
We don’t know that. Because there’s no way to see what the ball would do when it is not observed. Meanwhile the photon experiment stands, observing does change the behavior of what is being observed.
Not inferring, we KNOW from the photon experiment that observation changes things. The only question is how much other stuff gets changed and how it changes. It might not change anything dramatic about the flight of the ball, or it might, we don’t know that part, but something is changed. Quantum theory tells us the world is a lot more interconnected than anybody really thinks, reality doesn’t happen in a vacuum, observation changes the event.
Quantum is the teams 11th vehicle. The team finished Quantum earlier than previous cars, allowing for more testing time and time to design second iteration parts.
Probably will need a Quantum mechanic at some point.String Theory Ping List
I’m both stealing and not stealing that, not even I know for certain.

You need look no further than ‘pi’. With that ratio included in any equation an arbitrary limits point must be chosen. BUT, it is a fact that the greater the gravitational field, the greater the error ifan arbitrary value for pi is chosen with less than 100 or more decimal points.
Any means to measure any aspectr of an ‘object’ causes an interaction with the thing to be observed, even if one observes only the effect upon the medium used to make the measurement. The inclusion of intellect, arranging some means to measure a thing, adds one more variable to what is already an object being interacted with by the universe. Another way of saying it is, the behavior of the universe will continue whether humans observe it or not.

An electron interference experiment that provides impressive evidence of the wave-like behavior of electrons has been performed. The interferometric device has been designed as simply as possible and is described in detail. A standard electron microscope is used as an electron-optical bench.

This experiment is not “proof”. The paper is behind a paywall and is inaccessible to the public without a fee. It appears to use electrons to detect electrons. Obviously the detecting electrons impact the detected electrons. The experimental method of detection causes the interference, not the fact of observation per se.
