Trump "has expressed such outrage at attacks on Christians in Nigeria that he has threatened military intervention there... but here’s the awkwardness: Trump’s aid cuts are killing far more Nigerian Christians than Islamic terrorists are." @nickkristof.bsky.social

No opinion about this specific claim, but I do think we need more humanities in our lives and hearts and minds. And more arts. More history, more literature, more painting, more moral philosophy, more poetry. More thinking about and cherishing what makes human life special.
I don’t know about you but I sincerely believe that Zohran Mamdani’s BA Major in Africana Studies enabled him to understand our current conjuncture & its demands of justice. Humanities shape minds & in his case for the better.
I know white tech bros disagree as they continue to collapse our worlds.

Awesome new paper on galaxy evolution for the #astrosci crowd!
Should’ve posted yesterday! In a paper titled “Searching Within Galaxies for the Earliest Signs of Quenching With Spatially Resolved Star Formation Histories in UVCANDELS” we divided star-forming galaxies into bits to see how star formation changed depending on location over the last billion years.

I have no faith that the DNC will have any idea how to proceed from here. But let's forget that for now -- congratulations Mayor Mamdani, Governor Sherrill, and Governor Spanberger!

Huge fan of Dr. Katie Mack, and much love for all she does for physics & astronomy + outreach.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

We use score matching and a trick from quantum field theory to make a product-of-experts family both expressive and efficient for variational inference.
