I dont even understand what they are saying here. Something about the math of ponytails.

The Rapunzel Number provides a key ratio needed to calculate the effects of gravity on hair relative to its length. "That determines whether the ponytail looks like a fan or whether it arcs over and becomes nearly vertical at the bottom," Goldstein said in a telephone interview.

The research also took into account how a bundle of hair is swelled by the outward pressure which arises from collisions between the component hairs.

Scientists said the work has implications for understanding the structure of materials made up of random fibers, such as wool and fur and will have resonance with the computer graphics and animation industry, where the representation of hair has been a challenging problem.

The mathematics of computer graphics is a huge industry with degrees at university aimed at this task alone. Sometimes it is really fun. They had similar problems modelling water.

I have problems modeling water. It is not easy to get it to stay in shapes unless you freeze it into ice. You will not see a water sculpure.

That's because they haven't invented force fields yet . . . :whistling:

Oh I know all about the "The Rapunzel Number".

I saw the movie last year when it came out, and it was in 3D!

We are talking about the same thing are we not?........
