You may, perhaps, be wondering just what the Hyperbolic Coral Reef is?
So glad you asked!
It’s a project started in Australia by two crocheting sisters seeking to call attention to the destruction of the Great Barrier Reef.
Interestingly, there’s a mathematical angle to all this. I will likely not get this entirely right, but basically for some time mathematicians denied there was a hyperbolic function until Mr Vincenzo Riccati and Johann Heinrich Lambert came up with it in 1760. This despite the fact that many coral grow hyperbolically, so there were examples right under their nose (or toes).
And you can crochet a hyperbolic function by simply creating a chain and doubling it for every stitch–example below:
Very cool! I will have to learn more. The hyperbolic coral made remarkable ruffles.
You can catch Margaret Wertheim's TED lecture:
or just search on hyperbolic coral ted. it's somehow reassuring that everything is connected.
I've crochet a hyperbolic plane and knit several MÃ¶bius strips. The first makes a lovely scrubby as well as a cool mathematical object. The MÃ¶bius strip makes a wonderful scarf that doesn't fall off. Iâ€™m currently knitting a Fibonacci striped sweater â€“few people will know when I wear it, but it does amuse me. And darn if I didnâ€™t knit a Sierpinski shawl for a friend. Sigh!
Clearly –Marianne the math geek!
