My PhD ring was featured in this week’s Scientist Show & Tell for LabX and the National Academy of Sciences. When I first laid eyes on it at Jean Jean Vintage, I thought it looked exactly like a black hole with big jets shooting out of the top and bottom. I would visit it in the store and try it on periodically until I just had to have it. Since the ring looks like the artist’s illustrations of black holes that I use in research talks, it seemed like fate to commemorate getting my PhD.
