I few days back I inked a post about Douglas Hofstadter’s fascinating book Gödel, Escher, Bach: An Eternal Golden Braid, in which I showed a little item from the chapter Figure and Ground, which is about recursively enumerable systems. The tidbit I offered was a most unusual number series. Here it is again, for those of you who didn’t see it the first time around, or who just passed it by without really thinking about it:
1 3 7 12 18 26 35 45 56 69 …
I admit it takes a minute or two to make sense of it, but it is worth the effort. It is wonderfully strange, and is typical of the little jewels that are everywhere in that amazing book.
And don’t worry, I am not going to make a habit of posting retreads.
