Which is why mr Mandelbrot felt traditional geometry was completly out of touch with the real world

Elegant Universe isn't about Quantum so much as it is about String "theory," which as I'm sure most people know is not even a testable hypothesis at this point and may not be for a long time.
For a while now "Quantum" Whatevers have been treated by honest authors and snakeoil hucksters alike as a sort of magical bag into which you can fit any sort of plot device, and out of which you can yank any sort of crank mysticism; rather like "gamma rays" that used to make people superhuman and green instead of giving them masses of terminal cancers.
The problem is that the popular treatment of Quantum Whatsits generally hasn't changed in this regard. The truth is that despite all its counterintuitive and mindboggling claims and implications, QT is solidly scientific and has certain boundaries and limits (though more of the probability sort than the strictly possible sort).

That alone, was worth it

What was that article you posted on the old forum about granular space? _________________ ...if a single leaf holds the eye, it will be as if the remaining leaves were not there.

Huh, I could have sworn I posted a copy of this over here from the "news of the Oh My GoD you have got to be kidding me" thread in the casual chat forum.
Anyway, if you are going to talk about quantum physics, you should know your dimensions....

Thanks to Aaron Williams of Nodwick.com for pointing this out. It's awesome. I think I'll post it on the physics thread too....

I thought Torque posted it?
I remember posting one in which a simulation using granular space only produced a "universe" like our own when cause and effect were assumed from the getgo.
Anyway, I don't remember the link to the specific article.

hold up, there, sparky.
i was too lazy to read the entire wiki article, but are you disagreeing with me?!?!?!
cause if so, ima show you summat, boyo.
1. take your magical imaginary paper, and a magical pen that draws perfectly 1 dimensional lines, and draw an equilateral triangle on the paper.
2. draw equilateral triangles, exactly 1/3 the size of the original, that are sitting exactly in the middle of each of the sides of the original.
3. you will now have an object with, if you count only the lines at the perimeter, 12 equal sides, a star of david.
4. Now repeat step two.
5. Again.
6. And on into infinity.
7. You will be able to draw a square around the triangle with a finite area, even though the object inside has in infinite perimeter.
8. the object you have just drawn (sans square, duh) can be replicated by a fractal equation, and is thus a fractal pattern.
this effect can also be achieved with what is known in math circles as "the sponge" where you remove volume from a cube in roughly the same manner, and end up with an object of infinite area inside a finite volume.
plus, you're living in the proof that an infinite amount of a lesser demension can (mathematically, at least, although not according to the laws of physics, because none of these occur within the laws of physics, only within the laws of fractal maths) fit into a higher one.
time is the fourth dimension. would you ever say that, mathematically, a certain amount of time can only contain up to a specific limit of area? that's a non sequitur, right? well, yeah. it is. as is "a specific amount of volume can only contain a certain amount of area."
BOOYAH!

This step cannot be completed. Your pen will run out of ink.
and I can't tell why you think he was disagreeing with you.

Number one:

Number two:
because he only picked up on that one aspect of what i said, and directed me to wikipedia....?

You described only its powers of drawing lines of magical thickness! Surely you're not implying I should've assumed it had other magical powers that you didn't tell me about... at least not until your archnemesis is just about to defeat you, and your immeasurable will to survive and passion for saving the universe unlocks those new powers!

Uhhhh... no
Your only statement was that you liked fractals. How the hell am I supposed to disagree with that? Nope I was simply going yeah hey cool fractals! you know what else is cool 'bout fractals?
Originally the post was meant to feature examples of the differences between euclidean geometry and 'the real world' i.e. straight lines with a clearly defined length versus curved lines of a fractalish persuasion whose length depends highly on the way you measure them. And then I was going to direct you towards Mandelbrot and his comments on euclidean geometry and his proposed switch to a fractalbased approach. But then "I decided I couldn't be arsed" and you got a wiki link instead

Okie Dokie! Sorry I took it th' wrong way... still, cool thought experiment, huh...?
