This is fabulous.

It makes me want to go back to school and learn more math. I gotta tell ya, I don't think I've ever said that before.

Knit theory, only it's really crochet

Edit: I just read the rest of the article, and I'm amazed at how a journalist who appears to have a working knowledge of high-level math can't seem to grasp the difference between knitting and crocheting. She's not knitting; indeed, knitting wouldn't work at all for this project. She's crocheting, and doing something that anyone who has ever worked a ruffle knows how to do: she increasing the number of stitches exponentially each row, so she starts with a straight line of, say, eight chain stitches, and four rows later has 64 stitches that ruffle. This is the basis for any lacework pattern that doesn't need to lay flat, and I've done it dozens of times.

I've crocheted the hyperbolic plane! Cool!

OH! It's the square root? I was dividing it in half! Maybe that's why my circles were a little bit off and things got bunchy. I'll have to try again.

I'm 10 years removed from this stuff...thanks for the reminder. =)

Well, the formula is C = pi * r squared. Or is that the area? Now I'm confused. :)

You're right. I had the formula wrong. This is what I get for doing it without a textbook handy. :)

Once I thought about I realized that David and I had the same conversation about the area formula vs. the radius formula in the car last night...(yikes, if that doesn't say geek I don't know what does!)

Either way, it doesn't explain why my circles didn't fit quite right...hmmm...

No, to get the radius you divide by 2*pi, You had it right, velvetpage didn'ty. What she gave you was the way to get the radius from the area.
