Oooh lookee here! I joined a new server and community only for photos. Recommended by @FediTips@social.growyourown.services today. It’s supposed to federate with ActivityPub and play well with Instances using it. So here is a link to a well-known photo I shot back in 2007. And you’ll also have my account address by clicking into it. I’m cobalt there, no surprise! It’s not an account or place for conversation like most social media. But looks good for photography content only. Hope it works out! #MyPhoto #Rock #Geode #Arizona #Crystals #CobaltBlue https://vernissage.photos/@cobalt/7661752387937241821

💁🏻‍♀️ TIL: 🌋✨ #MountErebus on #RossIsland, #Antarctica, emits microscopic #crystals of elemental gold in its volcanic plume. Scientists found faceted #gold particles up to 60 micrometers wide in #snow up to 1,000 km away. The #volcano releases about 80 grams of gold dust daily, but how the crystals form remains an open question. 👉 https://www.sciencealert.com/the-worlds-southernmost-active-volcano-is-spewing-out-gold-every-day #geology #earthscience #earth #science #nature #atmosphere

Imagine being a scientist, and being told that your mere presence in a facility would alter the crystals being grown, that no joke you cannot step foot inside: Scientists who had been exposed to Form II in the past seemingly contaminated entire manufacturing plants by their presence, probably because they carried over microscopic seed crystals of the new polymorph Fact, not fiction! In materials science, a disappearing polymorph is a form of a crystal structure (a morph) that is suddenly unable to be produced, instead transforming into a different crystal structure with the same chemical composition (a polymorph) during nucleation and points for being airborne! In a few cases, such as progesterone and paroxetine hydrochloride, the disappearance gradually spread across the world, and it is suspected that it is because Earth's atmosphere has over time become permeated with tiny seed crystals https://en.wikipedia.org/wiki/Disappearing_polymorph #science #TIL #crystals
