More recursion after last week’s recursive map post
Last week I posted The most amazing â€œYou Are Hereâ€ map youâ€™ve ever seen, which featured a map that referred to itself. In the closing paragraph I referred to a book—Godel, Escher, Bach—on recursion. I’d read and reread the book in the 1980s and it stuck with me.
Not sure if anything would come of it, I wrote the author, Douglas Hofstadter, with a link. Beyond writing back that he appreciated the reference to self-reference, he noted the pattern in sending him a reference to him. Beyond that note, he included a diagram of the email noting the location of a red star in the email where the red star was.
I hope he doesn’t mind my quoting his email to me, in which I close with a diagram with a red star indicating the close of this post indicating the close of his email referring to the star on the map referring to a star in the real world that I wrote about in my last post.
I know I normally post on leadership, stewardship, fitness, and topics related to them, but I grew up geeking out to things like this and I’m indulging in phrases like “a diagram with a red star indicating the close of this post indicating the close of his email referring to the star on the map referring to a star in the real world that I wrote about in my last post.” even if no one else appreciates it.
And if you like it as much as I do, you’re welcome.
Dear Mr. Spodek — Thanks for thinking of me in your blog post with the map with the red star that represents itself — and for sending it along to me. Itâ€™s lovely! Somehow, sending the blog to the very person whoâ€™s mentioned in its concluding sentence seems reminiscent of the blog itself. It gives things an extra added self-referential twist! All the best from Bloomington, Indiana. — Douglas Hofstadter.
P.S. — Here is a diagram of this email (disregarding the role of text in it):
