Q about QM spookiness

[Mudhammam]

I''m seeing a bit of "observation" wafting - with implications to consciousness. Keep in mind, that when you see the term "observation" or observer - with regards to QM - they don't mean what we might intuitively feel that they mean. One particle can be an "observer" with regards to another particle. So any wondering of what effect consciousness might have on QM can start on very, very shaky ground.

But to delve further, I would have to invoke a greater power than my own. I refer to ( a quote often attributed to) the venerable Feyman
"If you think you understand quantum mechanics, you don't understand quantum mechanics."

Hope somebody comes along to satisfy your questions in ways that I cannot.

I was not aware of that. That brings a little clarity. How did they come to that? Seems like an odd application of 'observer.'
