Heading offline for a restorative break before getting busy again. Teaching both upper level statistical physics and observational astronomy this semester. And taking daughter to college. It’s going to be a lot.

The US could see a 30-40% decline in new international student enrollment, resulting in nearly $7 billion in lost revenue and more than 60,000 fewer American jobs. https://www.nafsa.org/fall-2025-international-student-enrollment-outlook-and-economic-impact

people are so weird about the radicalization of men thing.

if i told you that one social group was becoming violent and aggressive in response to a social group that they've traditionally repressed gaining resources and power, it would be immediately comprehensible.

My other reaction though is sadness that she doesn’t get to explore and learn from the other subjects and classes she would take in an undergraduate program.

Obviously this young mathematician is amazing.

But the article is an enjoyable read about the universal human story of looking for a path, for proof, the value of interaction w other great minds, & the silliness of institutions' valuing traditional credentials over the advances she *had* achieved.

There is nothing that gets my red flag meter going quite like men saying things like "it was hard meeting women because I was interested in (insert nerdy thing here)" when I have distinct memories of certain kinds of men in nerdy thing specifically and repeatedly excluding me from nerdy thing.

That our end of summer physics/astro research pool party has been called off* for thunderstorms and flash flood warnings kind of summarises how summer weather has been this year.

Reminds me of other advice (iirc this was from Christi Tremonti) that time being a co-author on other people's papers takes time away from your ability to work on your own first author papers. And at many career points the latter counts a LOT more than the former.

Helicopter parenting also removes opportunities to practice being responsible for things while the stakes are low.

Light pollution is encroaching on observatories around the globe – making it harder for astronomers to study the cosmos Some observatories that used to be dark and remote are now adjacent to bright urban centers. And sending all telescopes into space isn’t a viable solution.

Light pollution is stealing our view of the stars ⭐

Mountaintop observatories worldwide face growing skyglow from city lights and LEDs.

Protecting dark skies isn’t just for astronomers – it’s about preserving a universal right to see the cosmos.

Readers, if you don't know, course evals are often a nightmare for women & faculty of color. I've had friends & colleagues report students commenting on their appearance, using racial slurs, & making all sorts of misogynistic comments.
white male = genius, non-white/female = pushing an agenda.

Early on in my first postdoc I got advice I often think about. It’s usually better to prioritize one paper and get it out (and move on to the next) than to juggle all of them.

Rejoice! ‘Bend It Like Beckham’ Is Finally Getting a Sequel Those still reeling from the Lionesses’ historic victory have even more news to celebrate.

Someone just alerted me to this news by being snarky about it and friends, I HAVE BEEN WAITING SINCE I WAS PREGNANT WITH THE DAUGHTER WHO JUST GRADUATED FROM COLLEGE FOR A SEQUEL TO BEND IT LIKE BECKHAM.

Snark however much you want, internet stranger, I am choosing joy!
