I was hoping someone could explain, in terms I can understand, the movement of particles. Clearly I am not a scientist, but I just want to fully understand the idea that when particles are not being observed they either no longer exist or just do as they please. The example I was given is that when you are looking at your bedroom door it's tiny particles are aware they are being observed and appear as your bedroom door. However, when you look away the door might not exist at all. If this is true how do they know they are being observed? And if they are responding by either becoming positively or negatively charged based on the awareness of the others charges, how do they know they are being observed in order to respond correctly? I hope I have phrased this is an accurate enough way. I am sure it is apparent that I don't have a real understanding of the subject.
