Don’t Watch This Space

I had a rather long essay posted here, in which I made a dumb mathematical error that invalidated my whole premise.  (Figures are not my friend.) I removed the post not because I was embarrassed— at my age I’m pretty much immune to embarrassment— but because I didn’t want anyone as math-impaired as I am to link to it. Which was a shame, because it was actually a rather entertaining post. Sic transit gloria internet, and all that.
