Hey thank you for your reply. I learned several interesting examples from your first paragraph in the comment.

I do think your last sentence here was unnecessary though:

”That is that kind of thing I mean: proofs and calculations, not "why wouldn't it?"”

When I said “why wouldn’t it” I was asking out of genuine curiosity. There really wasn’t any need to criticize that part. It came off as maybe more hostile than I think you intended.

Again I most certainly appreciate you taking the time to type up the rest of your comment though because I did learn quite a bit from those examples you posted so I am indeed sincerely grateful for that.
