Hello all! I was recently watching a documentary which delved into the theory (is it a theory?) that quantum particles can be in two places at once; indeed, millions of places at once. I've heard this all before, but the one thing that I picked up on this time was that when a particle is "observed" by its environment, it effectively has a fixed position in space. I've often wondered exactly how electricity knows which path offers the least resistance, and then decided to take that path. I mean surely it can't just happen like that? However, having learnt that subatomic particles can be in virtually limitless places at once, is this what happens with electricity? Do electrons take every possible pathway, and the one that happens to be the shortest and most efficient is the one that is observed by the environment, and therefore is responsible for the phenomenon the we see and measure?
