    And you make even more sense than before. Yes, I stand corrected, your 2D image has some fractal behavior; it is a bit special as it seems to require one looks through a circular hole; that way you can hide the larger circles entirely while zooming in, something a square view fails to do for moderate zoom levels. The area problem remains; the odd/even rule still seems to lead to a half circle area. What does Gregory say on the subject? PS: excellent artistic skills indeed; why didn't you fill the interior to settle the area issue too? :)

    Still no idea what you are talking about there. It is an infinitely thin/long string wrapped in a bunch of circles (perhaps "loops" would be a better term, as the "circles" aren't filled in). There's no surface, so there's no area! You'll send me to the looney bin, you will.

      which metric? ha! Infinite length of edges, zero area and covers an n-dimensional volume. For an added bonus it's used to show that n-intervals have the same cardinality as the 1-interval. What's not to love? Your fractal only has an area that tends to zero, mine has zero volume before the limit :)

        That would be a fractal, such as this Sierpinski triangle[^]. ADDED Although not many would agree they have 2 or 3 (or any integer) number of dimensions... :)

        My fractal has less area than yours. neener neener neener.

          So now it is a spiral in 2D, it no longer is a collection of circles. Just an infinite line, curled rather than straight? That's a bit disappointing...

                It doesn't actually fill a volume unless you choose your radii carefully. For example if you pick r(i) = (1/2)i than you have finite sized gaps between each of the circles. You'd have to pick something like 1, 1/2, 1/3, 2/3, 1/4, 3/4, 1/5, ... so that it ended up filling the whole circle. Also without specifying the way that the radii decrease, you could end up with a finite length as opposed to an infinite one.

                      How about we say the distance the from the outer circle is a function of the angle. How about:

                      radius = 100 - 1/(1 + 1/(angle! + googleplex * ackerman(angle, angle)))

                      That ought to work. :rolleyes:

                        That's even worse! It converges even more quickly to a single point, leaving gaps over most of the circle and it most definitely has finite length.

                            Gotta be a CP bug. Here is the text I see when I edit my post:

                            My post:

                            How about we say the distance the from the outer circle is a function of the angle.

                            Could be because I put the links in a PRE tag. Let me test that: Not in a PRE tag.

                            In a PRE tag.

                            EDIT: Correct placement of blockquote start tag.

                              Yep, looks like the bug occurs when a link is placed in a PRE tag. I'll let you have the honors of reporting that one. :)

                                Nope. Let's go through it.

                                angle! + googleplex * ackerman(angle, angle)

                                Assuming you start at 1 for the angle, the result is a very rapidly growing number. Let's call this "growingNumber" for short. So the equation becomes:

                                100 - 1/(1 + 1/growingNumber)

                                Now, what happens when you divide 1 by a growing number:

                                1/growingNumber

                                You get a number that decreases in magnitude as the input increases. Since "growingNumber" starts out very large (at least a googleplex), that means this "shrinkingNumber" starts out extremely small (no larger than 1/googleplex), and only gets closer to 0 (but never reaches 0). So the equation becomes:

                                100 - 1/(1 + shrinkingNumber)

                                That portion in parens starts out as something like 1.0000001 (only with many more 0's) and keeps getting smaller, but never goes below 1 (because shrinkingNumber never goes below 0). So, the firt result looks something like:

                                100 - 1/1.000001

                                And a later result looks like:

                                100 - 1/1.0000000000000000000000000000000001

                                That first result would be something like 99.0000000001. And the later result would be something like 99.000000000000000000000000000001. The number gets smaller, but never below 99. So the circle goes forever, always with a radius between 100 and 99. Sure, it leaves 98 to 0 empty, but that doesn't make it any less infinite. :)

                                  Q: Describe a 2 or 3 dimensional shape with an infinite edge and zero area, which takes up a finite amount of space.

                                  How about a three dimensional figure that has an edge, but only one edge, and has only one surface, and encloses a volume?
