Afraid my math has deteriorated beyond recognition. Haven't used a Hamiltonian
operator since about?????? 1979.
Even mathematically guided intuition seems to come up short in some QM
situations. How about the case of the Delayed Choice Quantum Eraser? I
don't think
QM can get any weirder. Remember the double slit experiment I referenced?

Detected--wave fxn collapses--electrons acted as particles and two heaps on the
detector; not detected--act as waves with interference pattern and go through
both slits.
Now look at this!! Worth a view, I don't think you'll be disappointed.

Moose was looking for a macroscopic example of QM in action. Here is
another---the strange case of Reinhold Bertlmann's socks. He works in quantum
physics at the Univ of Vienna.

His colleagues observed that his socks acted as quantum entangled pairs. If
they observed him walking into the office revealing the left sock were pink,
the contralateral sock was always not pink. It was as if the
observation affected the results.
This phenomenon is even referenced in one of John Bell's papers--just read the
first paragraph or so.

Unfortunately the hidden variable is Bertlmann's dislike of wasting time
sorting socks, but I'll not ruin the story.
I would bet Moose and/or AG have excellent examples of quantum entangled sock
pairs to show us, Mike
