As a theoretical cosmologist, I'm frequently asked "what is the benefit of the work you're doing for people's lives?" Nothing I work on makes money or cures disease.
There are a few different answers one can give, at various levels of "convincing" / "actually relevant to why the work is done."

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 didn't come across that Earth, Wind & Fire meme this year, and that's how you know everything's in shambles.

It's been one week since this meeting ended. I missed last year's, so it was a great pleasure to attend this one. There were many fun moments with many good people - I'm already missing them! 🥹

Poll data from October showed this disaggregation of Latino voters by heritage (from www.as-coa.org/articles/pol...). We are not a monolith & have different experiences, but there's also a lot of anti-Blackness across the groups.
