It’s common for knitters and crocheters to say that they don’t like math or that they’re afraid of math, but the intersection of fiber arts and mathematics is actually a really cool place.
For two years now Math for America has done a mini workshop on knitting mathematics, which enables teachers to craft objects such as a tessellated plane, a Möbius band, a trefoil knot, a Klein bottle, and other two and three-dimensional objects.
Scientific American also explored fiber arts and math a couple of years ago, looking in on a session at the Joint Mathematics Meetings that considered math, education and fiber arts.
One of the people mentioned in that article is Sarah-Marie Belcastro, whose website is basically the home of mathematical knitting online. It’s fascinating, even if it does go over my head quite a bit. But it’s really interesting to see how complex mathematical objects and concepts can be illustrated with yarn.
