Indeed. It's at the level of beauty, romance, poetry, experience, the awe-and-wonder circuits (if one wants to get computational-theory-of-mind... which to me just makes a nice metaphor but not really accurate per se). Infinities are one of the religious components of mathematics. It has several others I can think of but that's one of the big ones. They're also very useful as well but the usefulness doesn't take away from the inspiration it brings to people. == holographic principle... fractal universe - even with our fancy formulations of it, it amounts to the crack that deepens with no end. == One of the places I think modern Sciences "misses the boat" with Newton is in his treatment of Impetus... well, Inertia. Newton had a distinction between internal and external Inertia. He was considering both as possibilities. We currently entirely reject the internal inertia in our modern definitions. It's a missed opportunity. Useful and practical? Sure, but it misses some good opportunities for further exploration by our insistence on objectivity.
