Felix Klein lectured “On Hilbert’s first note on the foundations of physics" at the Mathematical Society of Göttingen #OTD in 1918. He included excerpts from letters in which he and Hilbert give priority to Emmy Noether’s results on conservation of energy in general relativity. (1/n) 🧪 ⚛️ 👩‍🔬

Black and white photograph of Emmy Noether. She is standing just behind an ornate chair, wearing a white striped blouse with puffy shoulders, a fluffy bow at her neck, and a heavy long skirt cinched with a belt. Her dark hair is pulled back and she is looking a bit to the photographer's right.

🚨We analyzed 138 million geocoded property tax records to quantify how municipal boundaries spatially overlap onto economic segregation in every US metro area—creating disparities in localities’ ability to fund public goods. And we made an interactive map of our results! [1/16]

woah this is genuinely, utterly WILD Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers! This is so gloriously weird I can't quite compute it 🤯🧪🐜 www.nature.com/articles/d41...

‘Almost unimaginable’: these ants are different species but share a mother

Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

Three things made the US a rich and powerful nation: the rule of law, its science & innovation system, and openness to foreign talent. Remarkable how Trump has taken a sledgehammer to all three. No enemy of this country could do more.

Americans are in denial about the implications here because they wish it wasn't happening. But this is the behavior of a dictator. It's the sort of thing that warrants secession or revolution. The Republic is over the second federal funding is withheld pending a governor's personal apology.

Trump says he will withhold federal tax dollars to Maine colleges unless the Gov of Maine personally apologizes to him.
