Video Explanation of Crochet and Hyperbolic Space
My friend emailed me a link to this outstanding TED video of Margaret Wertheim discussing crochet's role in mathematicians' understanding of hyperbolic space and her project with the Institute for Figuring to create a crocheted coral reef.
I wish I could post the video here, but our new blogging system won't display it. So, go over there and watch it! It's a great way to spend sixteen minutes.
