The wave/particle duality isn’t really a duality.
Much that has been written about physics is complete crap, not surprisingly.
There is no there there. The electron is neither a particle nor a wave. Sometimes it is just convenient to think of it in one way or the other.
The electron is its own thing, both both* and neither.
The double-slit experiment is still very cool, but when you really understand electrons and fields, it is obvious rather than mysterious.
*I love it when I can validly duplicate words like that.
You just love it because Microsoft Word hates it, right?
These days, I avoid Word except when I can’t at work.
I’m quite enjoying Pages on the iMac. It’s not perfect but it actually has a decent UI, instead of the dreaded Ribbon.
