Golden ratio bracelet & necklace set! (The golden ratio = 1.6180339...)Planck's constant bracelet! (NB: Planck's constant as measured in Joules-seconds.) This is a test run of my new physics jewelry idea. Planck's constant seems to be the most popular so far, so I decided to play around with it to see what, exactly, can be done. Hope everyone's having a great and crafty new year!
