Suppose we position ourselves inside the core of an atom, the particle everything we see is made of. Around this core, an electron flies seemingly random. Electrons are even smaller particles than the core of the atom and has an electric charge. We can use these electrons to power our houses and stuff. As we follow this electron, it looks as if it sometimes is closer and sometimes farther away from us. It’s even possible it looks as if the electron is colliding with us. But the longer we look, the more of a pattern we can see. The electron likes to be at certain distances of us. Though it does not like other positions, such as far away, it can still end up there for a moment. If we look at all these positions the electron can be, we see, on average, the electron likes to be at a certain distance from us. This is what we sometimes call the time-averaged position of the electron.
