Double slit experiment on a moving train

Click For Summary
The discussion explores the implications of performing the double slit experiment on a moving train, focusing on the concept of simultaneity in different frames of reference. The original poster questions whether the speed of light being constant for all observers would lead to contradictions in the experiment's results, particularly regarding the detection of a photon by observers on the train and platform. Participants clarify that simultaneity is frame-dependent, emphasizing that events perceived as simultaneous by one observer may not be by another, thus negating the possibility of contradictions in outcomes. They also note that the interference pattern in the double slit experiment is independent of the observer's frame of reference, and the collapse of the wave function is not essential for understanding interference. The conversation encourages a simplification of concepts to better grasp the relationship between special relativity and quantum mechanics.

Yes, that was how I understood the question also, particularly given that this was posted to the relativity forum rather than the QM forum.

If you want to learn, then simplify. Don't deliberately add unnecessary complexity. You will only confuse yourself and make your own learning more difficult. Please decide which topic you want to discuss. The first belongs here (which is why I assumed that was the question you actually wanted to discuss), and the second would be better in the QM forum. But you shouldn't try to discuss both at the same time.

I find that as I learn Physics, I often try do exactly what you dissuade the OP from doing. I always thought it was a good way to get a deeper understanding of both of the admixed concepts.

Fortunately or unfortunately, that is the way my mind works. I take knowledge from one area and try to see what sort of conclusions I can reach by applying the concepts to another area of study.

Of course, taking a misunderstanding in one area and applying it to another does not work. But it may well illuminate the original source of misunderstanding in stark detail.

So I think that the admixture of concepts can be very valuable, even when (especially when?) it results in the identification of misconceptions.

In my experience that type of learning is not compatible with an internet forum as the medium for learning. Similarly, the Socratic method is also an effective teaching method face-to-face, but I have never seen it work successfully here.

If you and the OP wish to learn that way then, in my experience, PF will not be able to help.

Thanks for the thoughtful reply. I think that there is merit in your views.

I recently read the posting on properly formed questions that was in somebody's sig, and it offers good methods of obtaining satisfying answers.
