"Spooky Popcorn" is the name of my Zydeco Young Einstein cover band.

When my wife lets me fluctuate her quantums, the jiggle quite nicely, thank you very much.

I would like to add 10-20 m isn't exactly "human scale"

From my reading, the thing that was moved was an 88 lb mirror, albeit, just a tiiiiiiiiny, tiny bit.

Quantum effects propagating up to the macrocosmic scale was regularly a thing in James P. Hogan's physics-intense science fiction.  Still good reads today.

That road must be full of quantum fluctuations.

Whoa. In undergrad I read an essay by Linus Pauling, in his mid-career, that scoffed at quantum effects and human consciousness. He argued that memory and thought, and all neural activity that contributed to thinking, had to be happening at the chemical level rather than the quantum Level. he was fairly simple about his reason. Quantum effects, as far as his contemporaries understood it, could not reach across the distances necessary to influence a whole neuron, let alone travel from dendrite to dendrite, skipping across the brain.

He had a second point which I've also seen elsewhere. If quantum effects were to be part of consciousness, the human brain tissue would cook. But the heat generated by calories burned has been the physical limit of human brain activity for decades. (It is why we can't take a pill to make us think faster - the heat generated boils us since our brain has about as much cholesterol as egg whites).

Pauling was sure that consciousness was a subject for chemistry and not quantum physics, because of distance and temperature. I've always accepted his point.

There was a girl in college we called the quantum squeezer.

Wasn't there an experiment that showed the effect of virtual particles in a vacuum on pieces of metal foil?

Sorry, I'm not a scientist, so I probably expressed that poorly, but I thought there were quantum effects that could be measured at something close to the "human" scale.

You might be thinking of the Casimir effect

Of course they do. Have you ever dropped a small, and perhaps difficult to replace screw on the floor, and had it wink out of existence?
