We officially had our first freeze last night as the temperature at O'Hare dipped to -1°C. At Inner Drive Technology World HQ it only got down to 0.1°C, barely above freezing, but still cold enough to put on ear muffs and gloves taking Cassie to day camp this morning. It'll warm up a bit this weekend, though.
Meanwhile, I'm writing a longer post about propaganda, which I may post today or tomorrow. And that's not the only fun thing happening in the world, either:
- Ukraine has had a lot of success blowing up $2 million Russian tanks with $400 drones. Good.
- The XPOTUS keeps making fun of the President's age, which, like everything else he does and says, turns out to have a pretty large element of projection. (Remember: to figure out what the XPOTUS wants to do, listen to what he says our lot are doing.) Bad.
- Chicago house prices have risen faster than in any other major US city lately, but only because they still lag almost every other US city. Mixed.
- BlueTriton, the parent company of Poland Springs-brand bottled water, not only sells one of the worst products for degrading our natural environment, but also has engaged in ballsy corruption to "persuade" the Maine legislature to let it continue doing so. Bad.
- HackRead reports a 587% increase in "quishing" attacks, where bad guys get you to scan bogus QR codes to steal your credentials. Very bad.
- Paleontologists have published evidence that the dust layer kicked up by the Chicxulub impact 66 million years ago may have persisted for 15 years, shutting down photosynthesis entirely for up to 24 months. Bad for the dinosaurs, good for the paleontologists.
Finally, as you sniffle and snort this winter, it might not comfort you to know that you have two noses that can get congested and runny. Bad.
A fossil found in a mine in Alberta six years ago is one of the best-preserved dinosaur specimens ever discovered:
On March 21, 2011, Shawn Funk was digging in Alberta’s Millennium Mine with a mechanical backhoe, when he hit “something much harder than the surrounding rock.” A closer look revealed something that looked like no rock Funk had ever seen, just “row after row of sandy brown disks, each ringed in gunmetal gray stone.”
What he had found was a 2,500-pound dinosaur fossil, which was soon shipped to the museum in Alberta, where technicians scraped extraneous rock from the fossilized bone and experts examined the specimen.
The fossil, which looks more like a statue than a skeleton, is 110 million years old, and will be at Canada's Royal Tyrrell Museum of Paleontology.
In the last 40 years, astronomers have gathered more and more evidence that our moon came out of a scarcely-imaginable collision between a baby (100-million-year-old) Earth and another proto-planet named Theia. (Watch this video for a good explanation.) Just two weeks ago, astronomers at UCLA announced a clarification: Theia didn't hit Earth in a glancing blow, as previously thought. Instead, the two planets hit head-on:
“We don’t see any difference between the Earth’s and the moon’s oxygen isotopes; they’re indistinguishable,” said Edward Young, lead author of the new study and a UCLA professor of geochemistry and cosmochemistry.
The fact that oxygen in rocks on the Earth and our moon share chemical signatures was very telling, Young said. Had Earth and Theia collided in a glancing side blow, the vast majority of the moon would have been made mainly of Theia, and the Earth and moon should have different oxygen isotopes. A head-on collision, however, likely would have resulted in similar chemical composition of both Earth and the moon.
“Theia was thoroughly mixed into both the Earth and the moon, and evenly dispersed between them,” Young said. “This explains why we don’t see a different signature of Theia in the moon versus the Earth.”
So why am I reviewing catastrophic astronomical events? I'm reading Neal Stephenson's latest novel, Seveneaves, which posits (in its opening paragraph) the collision between our moon and what is probably a small black hole. Stephenson imagines what would happen from a serious, scientific perspective.
Seveneves isn't what you would call a character piece. I'm 45% through it, according to my Kindle, and thoroughly fascinated. But Stephenson is almost the anti-Ishiguro.
Another aside: I have to see the tidal bore in the Bay of Fundy someday. It just sounds so cool—especially in context.
Too many interesting things to read today. I've got some time between work and Bel Canto to get through them:
I have not read Bel Canto, though I understand it's loosely based on an actual historical event. I also haven't ever heard anything from composer Jimmy López before, since it only permiered last month. Friends who work for the Lyric tell me it's pretty good. I'll find out in a few hours.
