All of this is to say: Monday's a good day to do blog and Etsy stuff. Here's my next just-relisted piece of SciArt:
|Planck Constant bracelet in amethyst and fluorite.|
|Physics jewelry in action! Also: I have teeny-tiny nail beds.|
I love love love making things out of memory wire, which makes me the beading equivalent of a filthy casual I suppose, but sometimes you just want to put some beads together and not fuss with clasps and crimps. I also love wearing memory wire because it's easy to get off and on but surprisingly secure. I've never had a memory wire bracelet just suddenly come undone and fall off out of the blue.
The number in this piece is the Planck constant, a proportionality constant that describes the relationship between the energy of a particle and the frequency of its associated electromagnetic wave.
More specifically, it's a physical constant that can be measured in a number of different ways; the value I used here is given in Joule-seconds. This is mostly because I'm more familiar with Joules than electronvolts. Physical constants are also notoriously tricky to measure, so every once in a while their values are recalculated and recalibrated. The value I used in this bracelet is from the 2010 CODATA value, but CODATA values were recalculated in 2014, which makes this little piece of wearable nerdery a bit out of date.
The round beads are both amethyst; the large rectangular beads are fluorite. Those are all mostly purple but you can see flecks of green in them here and there.
