I'm not entirely certain that this should be here rather than somewhere more general, but it pertains specifically to this forum. There's quite a few posts from people essentially asking the same questions, often in various guises ("electrons"/"two slit experiment"/"wave-particle duality" ... etc.) Would it be an idea if we created a sticky to deal with most the most basic conceptual questions? Either a series of explanatory posts, links to decent material on the internet, relevant sections of the PF library, or similar. Or perhaps a thread with a particularly transparent discussion of the central ideas could be resurrected? I suspect that most people don't discover the PF library until they post on here and decide to follow one of the links that are automatically inserted. Any thoughts?
