That is excellent, thanks very much. I would say though that , perhaps, "Perfect" is a little generous, no? That is to say, if mathematics was an actually, "perfect" representation of the world (universe). It would mean that there would be nothing that it did not fully explain, i.e. dark matter, quantum gravity, the big bang, what is actually going on at black hole events horizons, etc. Know what I mean? Not that it won't, eventually, attain these mysteries, merely that "perfection" implies complete understanding currently. If that makes any sense...
