I haven’t really done mathematics in months, since I left my book at 55 pages. But this afternoon, after I took a nap, I decided to do this, a problem that had interested me on and off for a while. Otherwise, I’m working on a paper on Romance linguistics (”working” meaning I wrote 5 pages of it 2 weekends ago and never finished it, and will probably have to in a week or so). Also, I don’t use the spell check in my LaTeX editor, so this thing is probably full of errors. My apologies.
(EDIT: This version is now the updated version, to include perspective. I also fixed two typos).
As always, all writing is copyrighted to me.
