Here's an

infiniteline, which is a closed-loop, like a circle.It's all scrunched up in zigzags \/\/\/\/\/\/\/\/\/\/ but

Are you taking the limit of zero angle for each zig-zag? If so, I think you've got an array of pseudo-delta-functions with finite peak height, and therefore infinitesimal (read zero) area, but covering the plane. How close to the center do the peaks go? The enclosed area should just be the space strictly interior to the peaks. If I'm wrong, could you post the derivation? Feel free to use LaTeX and a GIF or PDF, since it's much easier and clearer than ASCII math :-/

I used the word

apparentbecause it's not a paradox. Figuring out what's wrong with it is the point, and I think you can see that.L

Select as Best AnswerUndo Best Answer

Yes, indeed! I wasn't arguing :-) I don't think you're wrong -- a fractal, after all, is a boundary of infinite length which encloses or covers a finite area. I am interested in the computational details, though -- how do you represent the zig-zags, and how are you doing the integration?

Select as Best AnswerUndo Best Answer

I don't - if it's infinite the angles must be zero, so obviating the thickness of any lines drawn or represented the enclosed area must be zero. Or without the zig-zagging infinite. It looks better on paper, but I didn't seek it out and post an image because these things work better for confusion without something to look at. It took me a little while to work it out (but I like thinking). L

But you know as well as I do that limits don't always come out intuitively. I'm interested in how you represent the zig-zag in the finite angle limit (i.e., an N-pointed star). Let's use the inner vertices of the star as the baseline. Give that a radius

r, so a circumference of 2(pi)r.For N points, each point has a base of 2(pi)r/N. In the small-angle limit (appropriate for large N), we can treat the sides as having a fixed, constant length

l, equal to the height, and hence an areaa= l×2(pi)r/N / 2. The area of the whole star is thereforeA = N×a + 2(pi)r

= N×2(pi)rl/N / 2 + 2(pi)r

= 2(pi)rl/2 + 2(pi)r

So, A = (2+l)(pi)r. Notice that the N cancelled out before we ever took the actual limit, so this result

isthe answer for your limiting case.Select as Best AnswerUndo Best Answer

You'd have N as infinity, rather than l - so you get a result. Hmmm, there must be some wonky-maths in here somewhere... L

Select as Best AnswerUndo Best Answer

That's correct. By construction I kept the height of the zig-zigs finite (think of one of those kitschy '60's era wall clocks), but made them narrower and narrower (limit as N -> infinity). The

wonky mathis precisely in taking that limit :-)Select as Best AnswerUndo Best Answer

Okay, E-R-IC. Was that a sufficiently interesting discussion of a paradox for you?

Next up ought to be quantum entanglement and spooky action at a distance, but it's already been done.

Select as Best AnswerUndo Best Answer

No, that's just nonsense. The naïve paradox (with correct punctuation and words) is

The statement to the right is false. The statement to the left is true.Statements like that are just semantic mumbo jumbo. Far more interesting are the true logical (mathematical) paradoxes, such as Gödel's Indecidability Theorem.

Modern physics (both quantum mechanics and relativity) are replete with apparent paradoxes (such as entanglement) which arise from our attempts to interpret results in a classical way.

Ummm..you proposed paradoxes, self-contradictory statements or groups of statements, or situations which are logically or physically inconsistent. "Nothing is impossible" is simply a falsehood, at least in this universe.

Due to your explanation i will not flame. What you say is also perfectly true, alot of people through ignorance think things are possible. Me and my faith, is not an example.

Yeah, bookmarks are always a great source for Truth. But how, exactly, do you write the citation?

Select as Best AnswerUndo Best Answer

But what if I have a pair of entangled bookmarks? Every time I click on the one, the other changes!

Select as Best AnswerUndo Best Answer

Unfortunately, they're only entangled as long as you

don'tclick on them. Once you do, you project them out into orthogonal (or parallel, depending on the specifics of the entanglement) eigenstates, and after that they evolve independently according to the Schrödinger equation._{You do know you were asking for it, don't you?}Select as Best AnswerUndo Best Answer

if nothing is impossible, that means everything is possible, meaning that it is possible to make something that is impossible, but, that would be impossible because everything is possible, except making something impossible even though it's possible because everything is not not possible.
