Differences in the chemical composition of urine caused by changes in diet mean that many medieval recipes for paint etc don’t work right unless you get the urine from someone whose diet resembles a medieval one. (Tested in illuminated manuscript labs, thank you book historians!)

Throughout the Middle Ages and Renaissance urine as source of ammonia remained vital to many processes including bleaching, tanning leather, dying, fertilizer, tinting pigment, & making gunpowder
When tackling the "All we need is STEM!" attitude, my response: Developing the vaccine was the STEM problem; distribution & getting shots in arms was the Social Science problem; getting people to trust it & combatting misinformation was the Humanities problem--which did we fail?
Also to anyone feeling like you should’ve accomplished great things in quarantine: remember that in 1521-2 Michelangelo was dealing w/ lawsuits & got so stressed he couldn’t concentrate on art & made nothing for two full years. Stress hurts productivity, no matter who you are.
The longer I work as an historian the more I keep reconfirming that one of the top rules of history should be: "Always look up everybody's mom."
*So much* that doesn't quite make sense makes more sense when you look up mothers and sisters and the connections that get left out!
I used "slouching toward Bethlehem to be born" in an essay, and the copy editor flagged it and informed me that slouching is not a verb of motion, and then I was sad.
Plato’s mother Perictione was a Pythagorean philosopher. As recently as the 16th c. some scholars considered her an equal of Socrates as Plato’s 2 teachers. 19th c scholars believed a woman couldn’t have been a philosopher & removed her from the story leaving only the male mentor
This is *good content* so it needs to be translated:
If Socrates had been a woman, as soon as she said "I know that I know nothing", men would have arrived to explain life to her.
Other gods' advice to humans: Be fruitful & multiply. Don't make idols. Don't murder. Don't take My name in vain.
Odin's advice to humans: Don't leave the house at night except to take a piss. Don't have sex with witches in a cave. When hiking, don't forget to pack a lunch.
There's a surviving letter of Lorenzo de Medici in which he writes basically: "Hey, mom, I left my favorite purple bathrobe at home, can you send it to me?" I find these familiar human moments helpful as we try to remember that famous historical figures were also just people.
The brilliant Lila Goldenberg, currently doing her book history Ph.D. at

, told me her book history class was struggling to recreate a green shade used for illumination, so she got urine from a weightlifter who ate super-high-protein, & that got the color much closer.
Antiquity: Plato's Mom was a philosopher!
Middle Ages: Cool! Like Catherine of Alexandria?
Renaissance: Great! I'll paint her in my daughter's room. Keep up your Greek lessons, dear!
Enlightenment: Another proof of equality!
19th Century: Must be fake, women can't be philosophers

Ancient Romans had their clothes professionally cleaned--with urine. The cleaners ("fullones") didn't use their own pee, but left vessels on the roads to be filled by passers-by, which they would then collect and dilute with water before using.

Also: it's perfectly normal to balance your laptop on top of a bunch of cold carrots to keep it from overheating because the file is so ridiculously huge. Right?

Agreed. And as writers in the fantasy & science fiction genres we need to be aware of how often monarchy is depicted positively in genre fiction, & to think carefully if we choose to depict it to make sure we depict its flaws & failings & help dismantle not valorize.
I don’t believe in monarchies, which means I don’t revere them and will do whatever I can, however I can, aggressively, sometimes passive aggressively, to dismantle them.
Yep, pretty simple. 😊

Yes, what historians really want: please sign and date EVERY DOCUMENT EVER! And include your full name plus all common nicknames. A brief marginal note on why you're making the document & how you feel about your current regime and/or other power structures would be handy too. ;-)
Gotta hand it to you, these massive choirbooks get the job done! Having a dated initial (1625) is pretty handy too.

If Clifford grows with love and is 30 feet from one kid it would take minimum 300,000 people’s love to make him big enough to fight the Fenris wolf (basing the size on wolf jaw ratio & the texts saying Fenris can’t open his jaw the whole way w/o his nose hitting the sky).
I have a partial and answer to this important question, from an experience interacting with a former student who had done an internship with a weapons manufacturer, which is interesting as an example of why it's so important that we teach people how to think about history 1/?
How does a person go home at night from a job making and selling vile, destructive implements designed to rip the life from fellow humans, then kiss their kids and sleep peacefully? How can anyone justify making a living this way?
Men, what’s stopping you from dressing like this?
Seriously, I own a copy of this outfit and it looks fabulous on everyone! Every body type, every weight! Renaissance clothes were cut to look good on everyone even as bodies change with age, so unlike modern things!
What the study actually shows is that masks aren’t effective *when proper compliance with masking instructions is low.* It doesn’t show masks don’t work, it shows that we need people to use masks properly for them to work. It shows we need solidarity & empathy.
NEW: One of the largest and most comprehensive studies on masks to date found they do almost nothing to reduce the spread of respiratory viruses.
The study was done by the Cochrane Review—a database long considered the Bible for evidence-based medicine.🧵

I remember a teacher friend was arguing with a parent on a school board who was complaining about budgeting, and teachers asking for raises. Friend asked "How much do you think the teachers here make now?" Parent answered "I realize it's probably not much, maybe $300,000 a year?"

While I smiled at the spirit of this line, the Sistine Chapel floor is paved with imperial purple & green porphyry mined in ancient Egypt, that cost way more per square foot than Michelangelo and his team were paid in a year. Ceilings got the cheap stuff.
“Another big strike in France.”
“France is always having strikes. I don’t get it, they have so much vacation, sick leave, some the best worker conditions in the world so why strike all the time?”
“…They have great worker conditions BECAUSE they strike all the time. It works.”
In addition to protecting bigotry & the other terrible consequences of this move, usually those DEI offices handle disability accommodations and emergency medical leave for staff & faculty. The impact on lives will be immediate and horrible.
All state-funded colleges and universities in Texas will have to close their diversity, equity and inclusion offices under a measure signed into law by Gov. Abbott.

After decades of museum visits around the world I’ve concluded that everybody who was anybody in history had a rock crystal bowl shaped like a duck. You wouldn’t believe how common they are in royal tombs, crown jewel sets: Napoleon to the Agamemnon tomb at Mycenae, St Peter’s 💯
Rock crystal duck-shaped vase. Culture: Mycenaean or Minoan craftsmanship. Found in Grave Circle B, Mycenae. Date: c. 16th cent BC. Collection: National Archaeological Museum Athens.
Yes, as a historian who studies multiple centuries I keep telling people we haven't been trying large-scale democracy very long, & the USA is still running the barely-updated beta software which had had no user testing, of course we're finding exploitable bugs.

It’s important to have large & diverse sample sizes, because if you use my data (Renaissance Florence) then 80% of men were bisexual and 90% of women were the Virgin Mary.

Now I want a T-shirt with "STET" in big letters, but when you look closely it's composed of tiny text with lines from major works and hilarious editorial notes like that. I bet everyone would want to wear it to Worldcon!
This toxic practice, in addition to the other horrors, is also lowering vaccination rates, because people who have been hurt by surprise billing in the past are wary of being told "it's free" and don't trust that there won't be a giant surprise bill for the vaccine afterward.
Of all the dysfunctions of the famously cursed US healthcare system, few are so obviously a total scam as "surprise billing." Here's how that works: you go to a hospital (often its ER) that is covered by your insurer, and then, despite this, you get a giant bill. Surprise!

Very much how I feel. We want AI and made a thing and named it AI but it’s not what AI is in fiction. Just as since 300 BC the atom was defined as the tiniest piece of indivisible matter so we wanted to split the atom & then named a complex thing with parts “atom” & then split it
saw ted chiang give a talk yesterday where he basically told a bunch of ai bros, "we are nowhere near having real ai, and what we call ai today is just a tool of capitalism. i don't fear ai, i fear capitalism" and the ai bros got their feelings hurt. it was great.
