2nd Brillouin Zone of the fcc Structure, designed by me

So let’s talk about photo organization.  I have 13 years of origami photos, and every month on this blog I select one to share.  How do I avoid publishing the same photo more than once?  Well I have a primitive but effective method.  I have one folder of unposted photos, and another folder of posted photos.  Whenever I post one, I move it from one folder to the other.

When my hard drive got wiped last month, I didn’t lose any photos.  They’re all still on my camera, and all the good photos are on Flickr.  But what I did lose was the photo organization.  That makes it harder to tell what photos I’ve already posted before.  I could just use the search bar on my blog (as well as the two blogs I used previous to this one), but that’s kind of annoying.

So, you may have noticed something about this month’s origami photo.  Yes, that’s right, this is a photo that I have already posted!  I’m very flattered that you have been reading my blog for at least 13 years, and have been paying enough attention to have immediately noticed this.  Very, very flattered.

Anyway, this is one of the first origami models that I designed, back in 2012.  It is based on the concept of a Brillouin Zone from condensed matter physics.  It’s a very specific shape–so specific that if you try to search for it, the only image you will find is my own origami model.  (In practice, physicists are only ever concerned with the 1st Brillouin Zone, and so nobody ever tries to draw the 2nd or above.)

It is not a good design, I can say that with many more years of experience.  It’s basically takes several other units from other designers, and makes small modifications to fit them together.  It did not require glue, but drooped noticeably under its own weight.

This model is long deceased.  Back in 2014, I killed it with physics.
