Acnestis [ak-NEES-tis] (n.) - The part of the back that cannot easily be reached to scratch. Used in a sentence: “Ever since our illicit dalliance in the back garden, my acnestis has been afflicted with a most infernal rash of Poison Oak, and Miss Drollup has ceased returning my correspondence.”

Physicist Dr. Ursula Franklin helped invent archaeometry--the application of materials science to analyze archaeological artifacts. She used modern physics tools to date/determine the compositions of ancient metals & ceramics to uncover how ancient peoples lived/worked. Born #OTD 1921. #WomenInSTEM

“Practice any Art: music, singing, dancing, acting, drawing, painting, sculpting, poetry, fiction, essays, reportage, no matter how well or badly, not to get money & fame but to experience becoming, to find out what's inside you, to make your soul grow.” IAN McKELLEN & the words of KURT VONNEGUT

If I had to share just one lesson from my decades of teaching, it's that the best way to learn is by talking to someone who disagrees with you.

Why am I posting so much about the #ReflectingPool debacle? Partly because it is so emblematic of the incompetence & corruption of Trump & his government. But also because of what it says about their hatred & dismissal of #science & expertise. Any # of experts would have stopped this if consulted.

Physicist Rosalyn Yalow co-invented a super-sensitive test (radioimmunoassay) that uses tiny amounts of radioactive tags to detect exact levels of insulin in blood & won the 1977 Nobel Prize in Physiology or Medicine (the 2nd woman ever to win in this category). She died #OTD in 2011. #WomenInSTEM

This book, and The Brain From Inside Out by G. Buzsaki.

What if everything we thought about how our brains work is fundamentally wrong? A new book challenges the deep-rooted idea that our minds are like computers, revealing how our cognition is far more complex and nuanced than mere data processing. 🧠

This is the problem with home schooling, private and religion-based schools, and state-based make-up-your-own-curriculum. Children are not getting a FACT-based education.

Saying it louder for those in the back: "The United States was not founded, in any sense, on Christian principles. It's simply not true." More people would know this if they were taught history without restrictions. History doesn’t fit your narrative. #Pinks @timothysnyder.bsky.social

Portrait of a woman, 1435. Don't know what I love more: the eyes, the subtlety of the purple robe, the incredible headscarf (the layers! the folds!) or the pins. The pins! Robert Campin, you did well.

More generally: Trump’s economic policy makes more sense once you recognize it’s just an elaborate bribe-solicitation mechanism.

This is very true! And as the research on the issue shows and as the Hungarian example confirms, and the Polish one before that, the key to large turnout is long-term, grass-roots organizational labor that helps people understand how their single vote is a dignified part of a larger transformation.

Like most bullies, Trump can be constrained only if everyone stands up to his bullying. Keep protesting. Go to town halls. Protect the vulnerable in your community. Keep speaking out. The fight against authoritarianism will take all of us — and we can't relent.

‘Mr. Nobody Against Putin’ Director: “This is about how you lose your country — through small acts of complicity: when a government murders people on the streets, when oligarchs take over the media… we all face a moral choice. But even a nobody is more powerful than you think."
