Awesome best principle maybe in nature.

2025-03-17 22:59:19 +0000 UTCIt is true that the you need many electrons to see the lines appear. It is also true that you can perform the experiment slowly - use a really slow source and add one spot to your output at a time as individual electrons dribble in to your detector. And the results are the same (though slower to arrive) as if you use a faster source. Now, if every electron went through slit A, there is no pattern - just block slit B to make this happen. Similarly with slit B, if you block slit A. So the trajectory of individual electrons change when both slits are available and these trajectories are not consistent with electrons passing through one or the other.

2025-03-12 03:27:05 +0000 UTCNew member. I don't buy it. The double (or x) slit experiment shows an interference pattern only for a large number of electrons. If you only emit one electron, you only get one electron at the target. So, the mathematics is only probabilistic description of a single electron. That is NOT a description of a single electron "searching" through all the possible paths and "choosing" one. Math is not reality. It is a description of reality at a macro level. Extrapolating this probabilistic description to some kind of "multiverse" reality is just mentalbation. (Yep. Made up a word.) OK. This is more philosophy than "math" but prove me wrong. Please.

2025-03-08 22:02:52 +0000 UTCI happened to have the materials necessary to do that experiment at home. Interesting to see it for myself. There was one thing different: I used a linear film instead of a double axis. The result was that I got a single dot rather than multiple.
