Easy test of QM

If you have a polarized light source (for example an LED computer screen with a blank white document full screen) and two polarizing filters (in this case polarizing filters for cameras) ... you can test this with 2, not 3 polarizers.

The consequences of this as approx. measured while I sat here, leads to the Heisenberg Uncertainty Principle (the choice of one or another polarizing filter in front (next to the LED screen) demonstrates non-commutivity of the experimental setup (as represented by square matrices), and even Bell's Theorem.

In my case, I used filters for circular polarization, not linear polarization, but it works the same.  Linear polarizing films are more commonly used for sun glasses.  Has anyone tried this?

Per on lecturer on quantum computing at Microsoft, all analogy fails with quantum mechanics, because our intuition is conditioned by the classical world we are born into, and in which 99.9999999% of our experience reinforces.  This is why quantum mechanics is hard to understand.  But the mathematics works, even if intuition doesn't (accepting the three axioms of quantum mechanics as applied to photons).  It is possible to carry out the mathematics with a little education.

There are different groups working to develop the frontiers of human understanding ...

That is one such group.  They accept the reality of Schroedinger's Cat as a real problem, not a thought experiment.  Looking at decoherence on quantum computers, teaches you something else.  But this is a neat film anyway.

Their approach is naturalistic.  Hindus call this the Net Of Indra, have known this qualitatively for millennia.

In decoherence (as seen in quantum computing) ... since the Schrodinger's Cat is macroscopic, there is enough going on with the cat and the box and the air in the box, to disturb the entangled state, even if the random trigger to kill the cat hasn't happened yet, or afterward.  Basically why it is hard to make holograms (you have to achieve extreme mechanical vibration isolation of your optical setup).
