> Does quantum theory say that precise information is unknowable or just unmeasurable? 'Unmeasurable,' I think, would mean only that there is no possible way to determine the information precisely, while 'unknowable' would mean that there actually is no precise information. The second is highly anti-intuitive, but intuition generally means nothing in quantum physics...

I just got another question popping into my head: I've not had many years of physics in school, so I'm not especially good at this. What I'm wondering, is: An electron orbiting an atom core, is that scientifically proven to be a particle while it's in orbit? That's how it's pictured when we learn about them, but since its position is so unmeasurable, I'm just wondering if there could be some alternative state for it.
