Two-slit question

>So each particle passes through one slot, but we do not know which one.
that's exactly what happens.
I don't know why you thought otherwise in the first place.

One photon doesn't create an interference pattern.
10 photons don't create an interference pattern.
you need a lot more.
But the probability of each single photon of being at a certain position on the screen follows the pattern.

Not really. Take a look at the path integral formulation of quantum mechanics and see what Feynman and HIbbs says on the double slit experiment.

>>8171733
particles don't exist

>>8171753
Can you summarize a bit of what they say about it?

From my understanding it's that as a wave, a "single" electron can pass through both slits. But then I'm told that a single electron can't create a pattern. So can it be a wave or not?

>>8171753
yes really.

>>8171744
>should be getting this with a single slit
.... we do

>>8171771
Nope.

If it were simply a particle, there would only be two lines instead of many.

Go learn how it works before you embarrass yourself more

>>8171789
do we ?

>>8171812
oh yeah I saw. it looks like an I shape.

If you actually read my post, you'll see you're making me say something I didn't say.
Just go get a fucking education and some reading skills. I do optics, I don't throw tennis balls through holes.

I strongly advise you to watch Feynman's QED lectures if you want to learn more. Actually, the concepts he brings up are very advanced and surprisingly complete. He just leaves out the math. It's one of the things that Feynman is best at, reducing theories to their bare concepts instead of wasting time with the math.

Watch all of them, it's worth it. Except maybe the last one, although it is kind of interesting how people back then thought about the problems we partly solved today.

so basically pop-sci.

>>8171987
It's different than most pop sci. Nothing he says is dumbed down or uses shitty analogies.

Even his messenger lectures use very little math, but you can understand everything taught in first year physics

>>8171987
Yes, but Feynman actually manages to convey the (pretty abstract) concepts of his theory. It's not just flashy images and dramatic phrases, he actually explains the real deal and most of its implications

Those few lectures are actually very useful for people who just start out with QFTs. Most books tend to be pretty bad at explaining what the overall concept of QFTs are.

This isn't even interpretation dependent; the detection at the screen has no requirement on what slit the particle traveled through and thus in all interpretations you cannot say it traveled through only one slit. Even in many-worlds where the particle does, indeed, take a single path, it may have still traveled through both slits as such a path must necessarily be a valid choice for the interference pattern to appear.
