[Origami] Coc: Role of OUSA Board
OUSA has an elected board, accepts monetary payments, and is nonprofit (I hope). And there is a convention subcommittee. Ordinarily, the Board is the body who is *insured* and has the authority to just by fiat state what the CoC will be. The discussion to this point is solely advisory, isn't it? The process would usually be for the convention committee to propose CoC and for the board to approve them. And then it is up to individuals in the community to decide if they can live with those. What is the value to the community cross-talk on this issue? Particularly *now* when every single last social media platform is tuned to stoke outrage and crosstalk. I have no guidance on what the content of CoC should be, but are not all the options and issues clear for an agendized Board discussion and decision? With best wishes, Galen T.

I'm even more grateful for another twitter of yours about your article in the AWIS (Assoc. for Women in Science) magazine about creating a physics department that makes science so exciting and welcoming that undergrads flock to it: http://magazine.awis.org/i/880805-fall-2017/24 pp 22-25 Lots of practical ideas there, and in the whole issue, that I'll be sharing with my ScienceMentors colleagues and kids -- thank you! Karen Karen Reeds Princeton Public Library Origami Group co-ringleader Volunteer mentor, ScienceMentors 1:1 http://www.sciencementors.org/ from Karen Reeds karenmre...@gmail.com Hi Karen! Yes, both were fun and rewarding. For the Masu tessellation, I have been working with fractals as a physics topic since 1989, and combining the traditional Masu with this bit of my research life is really cool. There is a strong theme in physics dealing with unifying seemingly unrelated ideas, and this is an example. The AWiS article describes the outcomes of a long-term project in my department to extend the benefits of a life studying physics to everyone who wants it... The most important things I have discovered as a physicist have to do with how to make an equitable program. So thanks for your comment! Please share widely (outside o-list)! I am convinced that physics can be a truly equitable enterprise, and we will all benefit from that. Physical sciences, computer sciences, mathematics have some heavy lifting to do in this respect ... the individual act of creation and discovery is tied to training AND the exact personal path someone has taken in life. It makes me nervous as hell thinking about the discoveries that have not been made because someone was turned away from this life. Best, Galen
[Origami] Sierpinski Masu tessellation
https://twitter.com/GalenPickett/status/919228877213282304 This started as a 20"square, divided into 32 divisions. Conventional box pleating, and the final model has a 10x10" "framed area" with a one division border all around so the model will fit nicely under a 10" mat. Each of the small boxes are traditional masu boxes, and the center box has an aspect ratio of 1-grid wall to a 4 grid base. Eight of these (with a slightly different "ninth" center panel) would make a stage 3 version. With best wishes, Galen T. Pickett https://www.etsy.com/shop/GeometricOrigami
Re: [Origami] Permission question (Dick and Serena LaVine)
...below quote as per list rules. With best wishes, Galen T. Pickett https://www.etsy.com/shop/GeometricOrigami Now, time for a little rant. I routinely use data and whole papers from my colleagues while teaching genetics and developmental biology. On the few occasions when I’ve informed my colleagues that I was using their work in a classroom setting, they’ve been utterly delighted that their work was worthy of being spread in such a fashion. None would have dreamed of having their permission sought for such a purpose. Now the work I’m talking about isn’t the exertions of one person for a day. We’re talking about years of highly trained and creative professional efforts. Why Origami is so special is truly beyond me. I agree with you ... But it is no use telling someone that they should give up their intellectual property rights. Some will gladly do so, others will definitely not. It is entirely the option of the creator ... not the consumer. The reality is that most (not all) origami diagrams, finished models, and even designs are essentially worthless. The same is true for published scientific manuscripts (the modal number if citations of a paper is 0). (And, FYI, the authors release their copyrights to the publishers as a condition of publication... You need permission from Wiley, e.g., and they will give you the right to more than "fair use", if you pay a license fee of several $1000s). Best, Galen Pickett

Re: [Origami] Self similarity in a smaller scale models
...all of these models fail the most basic test for self-similarity... at best we can say that each of these displays self similarity at a single point. A *very* simple and truly self similar model is the dragon curve from a strip of paper. A *very* complex and hard to execute model would be a Menger sponge. If I define a measure as being 1 at the tip of a petal of a hydrangea and 0 everywhere else, the fractal dimension of an infinite - stage model is zero everywhere ... except right at the center, but that is a finite set, so the overall fractal dimension is the same as for a point.

[Origami] Mesoscopicity
Yes. Not a word, But I have been experimenting with controlling not just the shape of the paper, but the decoration on the page as well. This is the opposite of the Sara Adams deal ... I think. The order in the folds as I have designed them is pure, absolute, crystalline (at least in intention, if not execution). The decoration is free-form, not linked particularly to the underlying lattice of folds, and is, if not outright chaotic, at least disordered, Adding the two of them in the same piece orders the decoration, and disorders the folds, leaving a middle-ground (mesoscopic) place where neither extremes are exactly represented. Which I like, scientifically, philosophically, aesthetically. https://plus.google.com/u/0/115624021374660826601/posts/A4RhRsMTJmk -- With best wishes, Galen T.

[Origami] The arrow-loop symbol
The arrow-loop diagramming symbol (turn over the paper) is useless, and in fact counter-productive, in Rokoan-style origami. There is just no convenient way to turn over a sheet that is connected by 4 corners to neighbors ... if you don't want to break a junction! This requires new folding sequences for some familiar models ... I'm calling this restriction one-sided origami. Most tessellation work (after the precreasing) is one-sided, but not all!

The compression factor of a full FT folded from octagonal closed-back twists is around 4 ... tessellations of the crossed box pleat have a ratio of 2, and the clover folds of Fujimoto have a ratio of 3, for comparison. This fold has a compression factor of 1.5, with important design consequences. For instance, 1-level versions of this I have elaborated into my Sunflower Array: https://www.etsy.com/listing/111972678/sunflower-array-midnight-starfire -something that would be impossible for a true FT (for someone of my skill, patience, and resources).

[Origami] Convergent folding
The biggest secret (almost approaching outright fraud) in tessellation folding is that the very repetitive nature of the pattern tends to smooth out the errors that usually accumulate when making a super-complex model. And, even though individual cells of a finished tessellation can have gross errors in them, the eye kind of smooths those out, too. You all know of what I speak ... points that are not sharp, precreased folds creaping away from their landmarks... What I do is seek for robust, and error-tolerant methods. Folding thirds by successive pinches is a great example ... no matter how bad your first guess, eventually you converge on those thirds. My experience is that a global fold should have about 5 landmarks that I try to eyeball a least-squares fit to. And if the first few are wrong ... eventually things straighten out by the averaging process. I really admire designers who recognize that errors are an integral part of this art, and accommodate this as a feature, rather than as a flaw. With best wishes, Galen T.
