Premises:
The real numbers include all the rational numbers and all the irrational numbers.
An irrational number has a representation of infinite length that is not, from any point, an
indefinitely repeating sequence of finite length.
A rational number has a terminating sequence or has an...
A very interesting experiment:
Bell-type Polarization Experiment With Pairs Of Uncorrelated Optical Photons
M. Iannuzzi, et al.
in arXiv:2002.02723 [quant-ph] or Physics Letters A 384 (2020) 126200
The autor(s) conclude:
"We may therefore understand that the measurement precedure adopted in the...
@Mr.Neumaier, I'm afraid that I am not a big fan of the Copenhagen interpretation, for me
the wave function is just a bookkeeping device, and collapse in the physics lab can happen from too
much coffee. The only physical thing is the interaction with a microscopic (read:subatomic,atomic etc)...
@Mr.Neumaier,
I was thinking about the elementary observer as a black box with a single
cell of "memory" or state, whatever, the elementary observation meaning interaction
or input, flipping a bit from 0 to 1. Changing the state of the observer. In this case
the state of the photon.
No...
If the condition (in the boundary of QM) for "the Moon is there" is an obsevation, a single
photon coming from nowhere absorbed or reflected on the surface of the Moon can be
considered THE observation.
A step outside of QM: considering spacetime curvature produced by by the mass of the
Moon is...
Try with Schmitt trigger IC, like CD4093 (four NAND gates) from Texas.
Needs only an RC group.This IC works up to 20V.
I made once a 100MHz multivibrator with SN74AHC1G14 Schmitt trigger gate,
unfortunately this admits only max. 5V

Our brain is part of our existence, our world, our reality.
If the "map of reality" encoded in our brain, is just a holographic
connection to actual reality and any argument about the sense of
reality implying dimensionality of our physical word seems fallacious
-as you say-the same...
You may put a chilled wall inside of chamber, at -50C. At 10 Pa, this value of temperature is below of the triple point of water,
so you can stop the vacuum pump and the water vapors will be collected by the chilled wall.
I think that this phenomenon is more complex.
Almost all materials(in this case, plastics) have shape-memory,less or more.
They "remember" the steps of the technological process of fabrication
(injection molding,sintering etc.) and may accumulate some frozen strains.
On heating, this strains are...
"shooting consciousness on a laser beam into the heavens"
This seems to be OK, with some improvements. Like mixing
music and comics in the beam, otherwise the travel-weary could kill you.
