All right I'll give it a go. Thanks for the help :)

Okay? So why does he write it like this then? Is it a "popular writing" thing? Another thing about the uncertainty principle. Could it be that it is uncertain where exactly the electron will hit the screen, because an electron spins around an atom and if it is "to the left" of an atom at the...

I am reading Brian Greene's book "the elegant universe". In there he writes about the Feynmans double-slit experiment and uncertainty principle. Under a figure (which I don't know how to insert, but it is only showing a scematic picture of a standard double-slit experiment) it says: "According...

Thank you again. I was thinking about the fact that the fired electron takes all possible trajectories simultaneously before hitting the screen. Instead of saying this, could it maybe be that the fired electron is not taking all the trajectories simultaneously, but rather "bumping" all the other...

I recognize this type of answer from somewhere. But I'll play along: why does it not make sense to ask the question? :)

Thank you for the fast answer. But isn't this huge, the fact that we don't really know if the electron we fired is the one hitting the screen??

Newbie here: Is the (single) electron leaving the "machine" in the famous double-slit experiment the same one hitting the screen? Please give a short explanation on how this is proved, thank you.

(OP) As famously known, Feynman states that the single electron used in the double-slit experiment takes every possible path simultaneously before coming to the final goal which is the phosphorescent screen. My question is: How sure are we that this electron really is the one that left the...
