|Root 2 necklace featuring peridot, rhodonite, bloodstone, and seashells by Kokoba|
Pi is usually the darling of the "math-for-the-masses" world, and it's easy to see why. It has a cool and instantly recognizable Greek letter for a symbol; it's a concept you touch on relatively early in your math career (at least in the US, I was in 6th grade when we learned about pi); you can make puns about pies and pirates.
Somewhere in my calculus notes there's a doodle of a pi symbol with a tail, some paws, and a rat face in pirate costume and the caption "pi-rat." It's probably been lost to time (and by "lost to time," I mean "thrown out with the rest of my calculus notes"). I don't think anyone was celebrating Root 2 Day on January 4, 2014 (or on April 1 2014, if you're in Europe). But pi gets a day every year!
So this is my tribute to poor, neglected root 2. I admit, I've played some part in neglecting it. Did you know, for example, that root 2 is the first number proven to be irrational? The Ancient Greeks actually cooked up an elegant proof on the topic.
There's a lot going on in this necklace: there's chips, there's cubes, there's regular round beads, and there's shells. But it still feels fairly balanced, rather than haphazard or chaotic.
If you want to show some love for an overlooked irrational, this root 2 necklace is available in my Etsy shop. I'm thinking I should sit down and whip up some more root 2 bling. Just for variety's sake.
