Math Monday: Introducing the Sonobe Unit

Math Monday: Introducing the Sonobe Unit

There have been numerous installments of Math Monday on origami or kirigami of one mathematical form or another, but today is the first time we’ve covered a classic workhorse from this genre: the Sonobe modular origami unit. One of the simplest and most versatile of the modular units, there’s so much to say about Sonobe that today we’re going to start from the basics (parallelogram one?) and next time we’ll take it to places I hope you’ve never seen it go before.
