Double Slit Experiment: Does Observing Affect Interference?

[Rade]

No. Humans cannot pass through both slits and then interfere with themselves. You can only get the interference when the objects are given the opportunity to pass through both slits (that does not mean either/or, it means *both*).

OK, thanks. So are you are saying that a "single" electron with mass can move though "both" slits at the same time (not either, or) because it is a wave function, and not a single particle ? But, if so, then why is it that this electron does not produce two dots on the screen, one associated with each slit that it moves through--since from above statement by ZZapper it was made clear that QM does not predict that a single electron moving through slits will produce two dots ?

follow the energy!

There is no change in how we describe the electron, other than to say it has transferred some of its energy.

I think You nailed it. So obvious. I should have seen it myself!
Follow the energy! Like a detective follows the money.
Is the following awkward statement true?
“Directed” energy causes the particle to become a wave. When that wave strikes a “solid” barrier (no holes or slits) it releases the energy at the barrier and becomes a particle.
