I have had the magical fibro sleep called "can't sleep can't wake up". My eyeballs are sandpaper. My brain is oatmeal. Unflavored oatmeal.
But to each of you... I offer support. A burden shared is a burden lessened. We're here. Each of us is a strand ina spiderweb. One strand can take a lot, but the web altogether? Oh, that can take so much more than just the individual threads all summed up!
Google's doodle honors a guy who helped us develop quantum mechanics.
Now, Einstein faced the ultimate horror of a genius's life.
His love of Newtonian physics unfortunately helped him uncover... quantum physics. That is, non-Newtonian. A seeming contradictiont o everything he'd held dear and loved.
The Unified THeory of Everything is basically the attempt to reconcile our everyday physics (gravity, what happens if you ski off a ramp too slow, etc.) and the WTF physics... Quarks and strange attractions (those are real terms in quantum physics).
So about a hundred years ago, a couple big badasses in physics had a quibble. One was Heisenberg, he of the Uncertainty Principle; the other was Schrodinger, of the cat in the box. Both agreed there's one reality. They disagreed upon its levels.
Heisenberg, for example, says we can't know both where and how fast a particle is, simultaneously. Why not? I dunno. That's beyond me. But Schrodinger's cat thought expdriment --- the cat is in the box, and is not alive or dead until you open the box --- was actually intended as a *slam* on the idea that reality is not, to some degree, "fixed" and unified. It now supports the Hesienberg Uncertainty principle. I feel bad for Schrodinger. He said, "Imagine a cat in a box. Is it alive? Is it dead? We don't know until we opent the box." Well, okay, for the sake of the thought experiment (no cats need be boxed, thank goodness)... that's so. Generally, cats in sealed boxes are dead or angry and it's easy to tell which by smell and the amount of racket the box is making.
But Schrodinger wanted to show the absurdity of thinking our reality is to some degree only what is perceived. Instead, his thought experiment now shows that "both alive and dead" are "true" until we open the box, upon which time the observed state of the cat (alive or dead) "shapes" reality so we can now ask anothe rquestion about the cat. E.g., who put the cat in a sealed box, and how do I kneecap the fucker.
However, Schrodinger lost out to the "copenhagen" interpretation (his pal Heisenberg and others), which allowed all kinds of what-the=whatness we know now as quantum physics. Ironic, btw, since old Schrodinger was instrumental in developing quantum mechanics. He didn't think we should try to apply quantum rules to our Newtonian reality, basically. Thus, the cat was meant as a paradox. It's dead or alive no matter your observation of it *after you open the box*. But everyone missed that point, and it's touted as the prime illustration of quantum physics, that is, it is all unknowable because observation alters reality. (No, your perception. Reality is. I'm with Einstein on that one.)
All this begs the question: How do you get a PhD in the unknowable? Isn't that the PHilosophy department?
As the late author Sir Terry Pratchett observed, there are in fact 3 states for the cat in the sealed box: dead, alive, or bloody furious.
Which just goes to show how limited those Nobel-winning physicists are in their thinking.
So if you feel like you are off-the-charts (even momentarily) ready to surrender.... Remember that Nobel-winning physicists can't always get the job done the way they intend, either. Poor Schrodinger. The paradox of his cat-in-box thought experiment was meant to show that there's always some reality, no matter what we observe. Instead, it's used to "prove" the opposite.
No cats have ever been harmed in the Schrodinger thought experiment. Probably b/c, as Pratchett observed, a cat locked in a box has a primary base state of being bloody furious!
Monday hugs, and I'm off to see the physio-doc and... uh... yeah. I'll let you know the state of my reality when I find out!
Good morning! (ish?)This item from Norfolk, Virignia, Associated Press: Headline in my area: FIREFIGHTERS RESCUE MAN FROM TREE TRYING TO RESCUE CATNORFOLK, Va.

Just letting you know what happened. Wednesday afternoon the site said I was banned. I contacted them via e-mail responses to a spammer I had reported. (Always need to keep the site safe.) I was heartbroken that some would feel I had abandoned them. An hour ago, I got an e from DS that said the banning was an error, so I am back with the many people I care about. Healing hugs to all,...
