is useful for fission-track cooling ages too -it's closure temperature is ~220°C (the temperature when the fission tracks are annealed away). John Garver's group at Union college (@geo_garver
) used ziron fission tracks to show that the same Adirondack rocks have been cooling since the late-Precambrian/Cambrian rifting of Rodinia.

Well., simple one: is more interesting, forms nice crystals, is like a memory and timing module, totally making its own thing. While the other contestant is just useful but rather boring, and unstable enough to drive a business of just fixing failed ones.

I'm leaning towards fluorapatite but will accept convincing either way. Feel free to explain why or is a better choice for this round of voting.

Okay so sounds like it should be chaos (shark teeth!) but really how much more controlled do you get than regularly regrowing all your teeth? (And why isn't that a thing humans retained when we evolved? Think of the $ we'd save on dental bills!)

tho. My understanding is Zircon sure has given scientists some fun times figuring out how it even WORKS re background radiation of the universe and time. Also, Dr who = Time Lord = peak chaos. Vote Zircon!

A frigate carrying hypersonic cruise missiles is going to be joining naval exercises with and in February.

From the Wikipedia page for the Zircon: "Its Mach 9 speed means that it cannot be intercepted by existing missile defence systems and its precision makes it lethal to large targets such as aircraft carriers."

Between drones and the fact that the US, China, and Russia all have missiles capable of taking them out, may be as obsolete now as battleships were in WWII.

As an aside, I'm pretty sure is not "Admiral of the Fleet of the Soviet Union".

Ruské strašení, jaké nové zbraně vyvíjí, je atraktivní jak pro propagandu, tak pro novináře, ale v reálné válce na 🇺🇦 by nás mělo znepokojovat něco jiného. Není moc relevantní řešit, že 🇷🇺 budou mít za 5 let ne 2,ale dokonce 4 rakety , 2053 možná i novou ponorku(a let.loď?)

Rusko může být silné, nastartuje-li masovou produkci munice (do starých "dobrých" děl a raketometů),či levných dronů. Toho, o co dnes žebrá v 🇰🇵 a 🇮🇷.

Masy zvyklé na bídu & destrukce území protivníka,to bohužel funguje.

Love that @MineralCup got a shoutout in today's episode for nicknaming as The Time Lord. Brought me back to the fun of posting all the memes during . Ahhhh, happy memories.

Russia sends ‘unique’ new hypersonic cruise missiles to Atlantic and Indian Oceans
scmp.com/news/world/russia-cen

The frigate is armed with the latest missiles, which fly at nine times the speed of sound and have a range of over 1,000km, claims president
They can overcome any defence system and are ‘capable of delivering pinpoint and powerful strikes against the enemy at sea and on land’, Putin says

So, I may have taken 550+ photos (until my phone almost died) and had my husband take 250+ photos. I'm not going to attempt to go through them until home with my computer. 🤣

I'm going to be ready for @MineralCup 2023!

I love the way the exhibit was organized. I could happily spend many more hours exploring the exhibit.

You might not think much of sand, but the minerals found in a pile of sand can reveal the lost history of long destroyed mountains: discovermagazine.com/planet-ea
