I suppose it works well because it’s designed that way. We abstract away the non essential and do our math. The results measure out in the non-abstract world well enough to be useful. So we keep on with it. This process is recurring, so we do math on our math. I think it’s fun to ask if this abstract world is real. I think it is. It’s a wonderful place in the mind to visit if you’re inclined to wander around without trying too hard to get anywhere. That’s my hobbyist point of view anyway.
