🔴 „Ich habe es geschafft, [der libyschen Küstenwache] die Position des Schlauchboots zu geben.“ Das funkte heute die von Frontex betriebene Drohne „Falcon01“. Unsere Seabird war vor Ort: ~65 Menschen in Seenot wurden danach abgefangen & nach Libyen verschleppt. 🧵(1/4)

And, almost forgot, the amethyst color is of course due to charge-transfer effects. So inorg chemistry, applied chem (silica fuse), solid state physics, nuclear physics, geology, cristallography, mathematics, you could almost think quartz is the holy grail of polymathy. #mincup #quartz

Shame David found this need to clarify the joke. NO real climate scientist would be only now waking up to the danger of climate change after working on "fossil fuel extraction" with the big oil companies for the past 3 years. His satire shows how messed up our perspective is on the real dangers.

I wrote this quickly at a bus stop and didn't realize it would go viral, or else I would have worded it better. But the point is that the media is too credulous about AI killing everyone in 10 years (how?) when climate change is killing people now and will only get worse (we know exactly how).

A very intricate carving of an octopus made from a colourless piece of quartz. It looks like it's perching on a boulder.

On display in the Natural History Museum, London.A double terminate crystal of slightly smoky quartz next to the octopus. It's from Grisons, Switzerland.

On display in the Natural History Museum, London.An example of the agate the three chimps were carved from. It's shaped like a V and is black on the outside and brown on the inside. An outline of the chimps is drawn on top. The agate is from Rio Grande do Sul, Brazil.
