Hello Polymaths:

This video by Margaret Wertheim is about female handicraft (i.e. crotchet) and its applications to marine biology and advanced mathematics. Covering such broad topics in only 18 minutes inherently limits the depth:

- geometric complexity of coral
- geometry of crotchet
- history of hyperbolic geometry
- generation of life thru collective collaboration

I viewed this presentation as "hand-waving" to some degree. She does not teach hyperbolic geometry in this video. I would think you already need to know what it is to understand this material.

In contrast the collaboration and modeling aspects are fascinating.

The video is called The Mathematics of Coral.
