[Origami] Our CPs haz been analyzed
Ken Yamamoto and Yoshihiro Yamazaki have analyzed the statistical properties of crease patterns by me, Jason Ku, and Satoshi Kamiya in the Journal of the Physical Society of Japan (free download): http://jpsj.ipap.jp/link?JPSJ/82/044803 Spoiler alert: our CPs are not statistically the same as crumpling. Whew! Glad we got that cleared up. (Of course, I know there are many folders out there who would disagree with that conclusion.) Enjoy, Robert

Whew! Glad we got that cleared up. (Of course, I know there are many folders out there who would disagree with that conclusion.) Well, yes, following one of your more complex crease patterns, the first attempt(s) might very well turn out quite indistinguishable from crumbling ;-) I do use crumbling in some origami works, but mainly as a means to change the properties of the paper before folding. The empirical discovery of Yamamoto and Yamazaki that the successive-folding process leads to a lognormal behavior sounds plausible. Intuitively the number of cells is doubled - at least locally - with each fold? Best regards, Hans Hans Dybkjær papirfoldning.dk

I am starting an origami group for residents of Missouri in the USA, called Show Me Origami.? We have a group page on Facebook, and the email address is showmeorig...@yahoo.com. In addition to sharing photos and information via Facebook or email, I am hoping we will be able to get together once or twice a year.? I'm located near St. Louis, and would like to connect with folders anywhere and everywhere in MO.? Please email me, or find Show Me Origami on Facebook.

Re: [Origami] origami sighting : folded pages create words

For example, the circle inside a P cannot be achieved unless you make cuts and then fold the corners in to make the hollow of the P It is possible to make, without cutting, O, P, g ... by using more than one page. The bottom of the O would be formed by one page and the very next page forms the top of the O. By alternating in this pattern, one can make it look very nice. A g would need to alternate through 3 pages. Brian K. Webb www.eorigamipublishing.com
