Margaret Wertheim leads a project to re-create the creatures of the coral reefs using a crochet technique invented by a mathematician — celebrating the amazements of the reef, and deep-diving into the hyperbolic geometry underlying coral creation.

One thought on “Margaret Wertheim: The beautiful math that links coral, crochet and hyperbolic geometry

  1. Ah the lovely pretense of art– albeit for the best of reasons. But think of the billions of hours the corals took to build themselves…

    Fascinating. Knot theory. Hardly geometric nor geodesic. Look only to the lowly diatom or protist, the Venus flowerbasket, the spider’s web to follow the exuberance of life’s forms.

    You can do this in metal, it’s called Anti-clastic raising, stretching the edge– in fact it ultimately curves upon itself, a toroid from a flat like time itself.

    (like what happens when you add an extra loop per row…)

    But phylogeny? Natural progressions are more like fractals than knots. And don’t forget the helix.

    Hyperbolic or hyperbole?

    The Play-tank, philosophy of life through sweater construction– A performance… but still cozy and warm, pliant connections notwithstanding…

    All that aside, sounds like an intense installation!
