Zhoubi Bowl, by Philip Chapman-Bell

For this week, we've got a nice, deceptively simple bowl from Philip (you might know him as oschene on Flickr). I say deceptively simple because although it's not to hard to fold, the math behind it is fascinating, and surprisingly complex, when it gets down to it. There's a division by sevenths in there, and even an allusion to a proof for the Pythagorean Theorem from an old Chinese mathematical text.

Diagrams available here.

  2. The first design I tried so far from your lovely selection. It is simple enough to show more advanced techniques to beginners like me.

    I enjoyed making it and will be back for more :)!
