Natural Science 301 Guidelines
This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.
As usual, Tweb rules apply. If you haven't read them now would be a good time.

Originally posted by Boxing Pythagoras View PostYes, but with the clarification that an electron is a quantum. It already is a minimal unit. So, in the double-slit experiment, the photon/electron/other-quantum which passes through the slits is the cause of the wave-like behavior depicted by the interference pattern on the detector screen.

Originally posted by JimL View PostBut the electron itself, if i am not mistaken, only goes through one of the slits, or are you saying that the one electron, as an electron, as a physical entity, passes through both slits at once?"[Mathematics] is the revealer of every genuine truth, for it knows every hidden secret, and bears the key to every subtlety of letters; whoever, then, has the effrontery to pursue physics while neglecting mathematics should know from the start he will never make his entry through the portals of wisdom."

Originally posted by Boxing Pythagoras View PostThat would accord with most interpretations of QM, yes: a single quantum-- one solitary electron, in this case-- passes through both slits.

Originally posted by JimL View PostOkay, you know better than I do, I'll have to look further into that, but it seems impossible. What if the slits were placed in a ten mile long surface and there were a million or a trillion slits, would the single electron pass through them all?"[Mathematics] is the revealer of every genuine truth, for it knows every hidden secret, and bears the key to every subtlety of letters; whoever, then, has the effrontery to pursue physics while neglecting mathematics should know from the start he will never make his entry through the portals of wisdom."
