It is painful to read the blithe dismissal of scaling and of emergent properties In renormalization, you are setting scales. The beautify of renormalization is that it “resets” at each scale; that is, no longer do the rules of ATOMS apply at the next scale because there is a NEW basic unit. and so on. In short, there are RANGES of behavior. Outside of those ranges, atoms don’t matter. The next level doesn’t matter. The level above or below that doesn’t matter. New units are used at each scale.
