Very rude to make us put all the DECLINED proposals we've submitted in our CVs for tenure.

Bookmarking this, as I started using uv but keep forgetting how it works 🙃
uv makes installing and using Python *so* easy! It works on pretty much any computer and it's lightning fast. 🔭☄️ #astrocode
If you're still using conda, pyenv, or... basically any other tool, then I can *highly* recommend switching:

Re-upping my take that many swing voters aren't really moderates: they're actually a collection of highly chaotic (and sometimes deeply insane) beliefs that, when mapped onto a simple left-right spectrum, cancel each other out.
Swing voters aren’t confused or undecided. They’re asleep
They imagine a swing voter as a cross-pressured moderate who will be persuaded by whatever side seems most reasonable, when the reality is most swing voters aren’t paying attention to policy debates and only wake up for sensational controversies that cross over into mainstream discourse

This is incredibly asinine, and also completely unenforcable.
Ohio State just advised all staff and students not to attend the SACNAS (Society for the advancement of Chicanos and Native Americans in Science) annual meeting of 6000+ scientists -- which is in Columbus, OH this year! -- saying it may be exclusionary, even though it is open to all.

I love how every choice Adams makes maximizes the entropy of whatever space he's in. God I'm going to miss him.

How is the tech industry ok with this?
Of all the stupid things that this regime has done, this is right up near the top. Postdoctoral researchers come to the US on H-1B visas. This will further destroy the US science enterprise. Stupid stupid stupid.

How many/where do you put hyphens in "extreme mass ratio inspiral"? This feels like something the GW community has a lot of thoughts on.

Great paper on stellar streams led by Carnegie Postdoc Nondh Panithanpaisal. Specifically, streams formed by globular clusters pulled apart by the gravity of their host galaxies. But because they trace the full gravitational potential, they're an excellent way to measure dark matter in galaxies.
