Old news, but there’s nothing self-referential about a formula that draws all possible bitmaps of height 17, where the bitmap is encoded by the gigantic number n (not displayed in the image!) that defines the y coordinate where we choose to start the graph. Tupper himself didn’t even call it self-referential.
For more details on how it works, see my Quora answer: http://qr.ae/TbcJFK http://qr.ae/TbcJFK.
- schoen 9y agoI was just going to ask whether one could port a full-fledged quine to this "platform", and then your Quora answer went on to exhibit one (!). Awesome attention to detail on your part as well as the constructor's!
- amelius 9y agoThe bitmap is 105x16==1680 pixels, or bits. And 2^1680 is about 5*10^505, which is about the magnitude of n. So, indeed, nothing to see here.
- jwilk 9y agoIt's disappointing to see a supposedly serious encyclopedia call Tupper's formula "self-referential" and even "amazing". :-|
