Is a "live" observer important in a quantum experiment with two slits?

Question

Physics

Have physicists tried to fix an electron with devices, but without determining which slit it passed through? (It went either through the right or through the left, but the device does not say which one specifically.)
Have you tried to fix through which slot the electron passed, write it to the hard disk, and then destroy the hard disk so that no one can ever find out through what slits the electron passed through.
In short, they tried to determine whether the observer is important and whether it is important that he "understands" what he is observing? Is it important to know which slit the electron passes through? Or is everything simple and the wave function is "destroyed" during the measurement because it is impossible to determine the position of the electron without affecting it in any way, and the observer / non-observer is no longer important, the main thing is to destroy the wave function?
I have physics at the level of 10-11 class. Maybe I just don’t know some fundamental thing and that’s why I ask stupid questions. You tell me what to read or watch on the topic.
Googling does not give anything specific, but I would like links to studies / experiments.

Answer 1

And what do you think they fixed? eye? But is the eye a device? and what was fixed after the eye? With the brain? The brain is a cunning organ. But memory has not yet been found there. And then what do you fix, that is, what are you if not your memory of yourself? Does an observer exist at all? You see) There are whole treatises in philosophy proving that the object does not exist and everything is subjectivity.
You can read anton wilson quantum psychology or the evolution of consciousness. I don’t remember exactly where at the end of which book he tried to analyze the aspect of this corpuscular dualism)
The same with Schrödinger’s cat. Whether the cat died, we will find out only when we open the box. But for a comrade behind the wall, the cat continues to be in superposition.

Answer 2

A strange question, since the essence of the experiment is to see the results. Why do an experiment, the results of which we will never see.
And although the question is quite interesting, it is meaningless. I think physicists already understand what will happen in the end.
Well, about the experiment with two slits: it shows the phenomenon of wave-particle duality. And this is a little different. A living observer is necessary here by definition. But overall, it's fun. In general, Young's experiment is one of the most important experiments, subsequently extended to electrons. Which is pretty interesting. You can look at something like this , it's better not to find it, since the experience is very old.

Answer 3

In fact, everything is much simpler.
Trying to determine which slit an electron passes through, we influence it.
There is no observer here. We can't see an electron with our eyes, can we?
We try to measure - we change the state.
I think it's called the Heisenberg Uncertainty Principle.

Answer 4

Question: Have physicists tried to fix an electron with devices, but without determining which slit it passed through?
Answer: tried. interference is observed .
Question: Have you tried to record which slit the electron passed through, record it on a hard disk, and then destroy the hard disk so that no one could ever find out through which slits the electron flew through.
Answer: tried. interference disappears (well, if you completely destroy everything, then it will be restored))).
The very fact of having information about the measurement is important. If it is, the interference disappears. If you ( your mind) can even hypothetically obtain this information - the interference disappears and we see the classical world.
