From what I am reading in this and other posts, I don't see that there is any critical disagreement on the subject matter. I am not referring to other situations at all, only the double slit experiment. And I am not trying to make any "point". I am trying to get a better understanding of this...
Just to be clear, with "observation" I am only referring to the primary which-slit observation / detection in the double slit experiment, not observation /detection in general. With "primary" I mean that by just removing this which-slit observation / detection from the experimental setup, the...
Thanks, I agree. I believe that some of the confusion originates from the term "Observation" in reference to which slit a particle has chosen. I am not saying that the term is wrong, on the contrary, it seems adequate. But it can easily be associated with visual observation, and apperantly, in...
Thanks. I agree. A camera, eyeball etc focused this way would not be able to detect or observe the photon for the reason you stated. As I understand, one needs some other way of checking the photon's path such as polarized films on each slit (90 degree difference in angle between each film) when...
Thanks for your reply. Please note! The imagined perfect model of the human eye would only be watching the 2 slits, not the detector screen behind where the interference pattern may or may not emerge.
So if I understand correctly one CANNOT make the interference pattern go away by placing an...
Thank you for your answer. I agree that consciousness per se is irrelevant for the outcome and apologize that my question wasn't clear enough on this point. What matters is the primary detection generating which-slit information, not if this information is made available to a conscious observer...
Are there any actual experiments that have been made where it has established if the naked eye can kill the interference pattern on the detector screen in the double slit experiment, that is, can the naked eye somehow function as a detector in this experiement? Let me give an example to clarify...
