firecat: red panda looking happy (Default)
Over on Facebook someone shared with me this video about the use of yarncrafts in mathematics:

Here's the accompanying article:

I've been collecting links about this subject for a while so I offered to do a linkspam.

Particularly rich sites to investigate:
Dr. Sarah-Marie Belcastro's mathematical knitting page.
http://www.toroidalsnark.net/mathknit.html
WoollyThoughts.com, the yarncraft home of mathematicians Pat Ashforth & Steve Plummer.
http://www.woollythoughts.com/
They also have a Ravelry group.
