Thought vs Matter/Energy Hello Gary
The shape does mean something. If we had 5 eyes maybe we would see shapes different, a circle may appear to look more like a triangle. Who knows. The point is how we are built as humans has a lot to do with how we interpret our reality.
To answer your initial question from the start of this post, it’s our position, our physical position in space, that gives us this outcome. Having two variables, both a probability or/and a determined state exist because of our physical position. We are bigger than an atom so we see probabilities when we look in and we are smaller than the whole universe so we predict outcomes easily when we look out. If we had the ability to shrink ourselves smaller than an atomic nucleus and looked out pass an atom and out to the universe we would see the same determined state for both. If we made ourselves bigger than the universe and looked in we would see probabilities for atoms and planetary movements.
Back to my shape, we are physically built to see our surroundings through a specific shape. How we see an atom having a nucleus and electrons has more to do with how we are built than what we are measuring.
To see the image I’m suggesting we see through; search google for Spyroe Theory.
