While the Fields Medal celebrates the under-40s, the mathematician Joan Birman has, at the age of 99, solved a major open problem in representations of the Braid groups, a topic she has worked on for more than 60 years.

Twice a year, Hawai'i experiences a strange moment where the sun appears to be exactly overhead & anything that is completely vertical casts no shadow. Let's learn about Lāhainā Noon, subsolar points & 'Kau ka lā i ka lolo', meaning "the sun rests on the brains."

From a Reddit forum, a photo of a can of coconut milk with a blue label, papyrus text and a flip-top, on a sidewalk.  It seems to hover because there's no visible shadow.  The pavement is sort of unevenly colored, with bright spots, and the grass along it is green and lush.

This is dangerous. The minute you start limiting what can and can not be studied, you start biasing your results. Just because you don’t like - say climate change - doesn’t erase it. Ignoring a problem, limiting what words can be used negatively impacts research & our ability to understand the world

Our PhD student Kennedy Orwa, who studies applications of AI to health care, was hastily deported today to Kenya along with his 13-year-old son without opportunity to speak to legal counsel. King 5 reports that he held a valid visa that was rescinded without explanation.

Donald Trump is deranged. He must be impeached and removed from office. Republicans who don’t stop him will have blood on their hands, and anyone who carries out an order to bomb civilian targets will be complicit in war crimes and will be held accountable.

Trump: “A whole civilization will die tonight, never to be brought back again. I don’t want that to happen, but it probably will … We will find out tonight, one of the most important moments in the long and complex history of the World. 47 years of extortion, corruption, and death, will finally end”

Trump: “A whole civilization will die tonight, never to be brought back again. I don’t want that to happen, but it probably will. However, now that we have Complete and Total Regime Change, where different, smarter, and less radicalized minds prevail, maybe something revolutionarily wonderful can happen, WHO KNOWS? We will find out tonight, one of the most important moments in the long and complex history of the World. 47 years of extortion, corruption, and death, will finally end. God Bless the Great People of Iran!”

Completely unstable and perilous. The House must bring up impeachment articles, and the Senate needs to remove a president who wants to commit war crimes. We cannot sit idly by as Donald Trump threatens to end an entire civilization.

Trump warns ‘a whole civilization will die’ if Iran doesn’t make a deal
The president had issued a deadline of 8 p.m. Eastern time for Iran to open up the Strait of Hormuz, pledging destruction by midnight if leaders don’t comply.

Trump is completely unhinged. He's lashing out with no plan, threatening horrific war crimes after already bombing a girl's school. It's making the entire world, including the United States, less safe. Every Republican enabling him is responsible. Congress must act.

Trump’s unhinged threats of violence and genocide are inexcusable.   He is a warmonger, escalating the conflict for his own profit and consolidation of power.   My Republican colleagues can't keep turning a blind eye. He must be stopped and impeached.

Breaking news: President Trump said “a whole civilization will die tonight” if Iran doesn’t accept his deal to open the Strait of Hormuz by 8 p.m. Eastern time tonight, pledging destruction by midnight if not.

That was a multi-day story. The story where the former top general who served as Trump's chief of staff warned he was an insane fascist got buried on A14 and never mentioned again. In retrospect, perhaps more important than the Walz thing idk.

The media told us, based on the amount of coverage they devoted to it, that the number one military-related issue of the 2024 campaign was whether Tim Walz retiring from the National Guard after 21 years was too soon or not.

Thing is, it is hard to tell how/where/who wanted this. Like anti-vaccine sentiment, this level of slash and burn appears to be enthusiastically backed by a very narrow slice of right wing elites. And we're in a spot where knowledge that this has happened is very, very low.

Genuinely just bonkers to watch the USA do this to one of the most successful and innovative hubs of scientific research the world has ever seen. All those years of Free Speech On Campus debates and it turns out they actually wanted less cancer research. Absurd.

ICE has arrested and detained a Nashville journalist who reported stories critical of ICE. She’s married to a U.S. citizen and has been seeking asylum here after fleeing death threats in Colombia because of her journalism there. They’ve already sent her to Louisiana.

We seem to have collectively decided, gradually and mostly out of apathy, that presidents can launch flagrantly unconstitutional wars of choice without congressional approval and there just won’t be any consequences. Would be nice if this is where we start reversing the trend.
