Solidarity with Emily Tucker and her open letter to students. Tucker writes, "But the great thing is, you don’t have to go along with this, and I urge you not to. You can refuse to use the chatbot. You can tell your professors that you don’t want them to use it or to require you to use it."

“Progressive taxation is the single most important policy lever for reducing the power of the rich—not because it raises revenue that can be redistributed via public programs or directly to the poor, but because it imposes a de facto statutory maximum on income or wealth.” @econmarshall.bsky.social

I have an astrophotography joke unfortunately the humor is both dark and flat

ME: oh a little Zohran video for St Patrick's Day, probably just celebrating Irish culture, maybe a few green beer jokes ZOHRAN (2 minutes in): ...and that's why King Leopold I of Belgium is a big wet bitch. Furthermore...

In the NJ case where the AUSA got tossed out of the courtroom: Bahahahaha!

OK so this young trans gentleman was cut off by his parents, has been unable to get MIT to up his financial aid, has been working multiple jobs while maintaining an A- average AT MIT (no one does this), but he is gonna need to actually pay his tuition to graduate: www.gofundme.com/f/help-matth...

Always a good time these days to repost this slide from an IBM internal presentation in 1979.

The astrophotography life

Very dystopian timing. I’ve been working on this since November. Thanks @thedialmag.bsky.social

Here is a video explaining the pre-Haber Bosch geopolitics of natural fertilizer (bird poop, or “guano”) youtu.be/ljbPWvIdZ7w?...

Chemistry in current events: the connections between fertilizer, the Haber-Bosch process, and the Persian Gulf. Read this and your knowledge will exceed that of most of our current political leadership after only a few minutes of light work:

Eugenicists seek to eliminate vulnerable bodies, and part of the way they do that is by claiming that the vulnerable (weak/ill/deformed) body is a physical expression of inward character defect. Dorian Gray without a portrait in the attic stuff

There's a broken cuneiform tablet from the Old Babylonian period, nearly 4,000 years ago, which preserves a tiny portion of a dialogue between two friends. It feels a bit like the conversations I've been having for the past week, so I wanted to share it.

In this current harsh world, let's warm a few hearts remembering the events of 7-8 March 1991, when the 90,000 people of Brindisi woke up to find 25,000 Albanians roaming the streets of their town. For perspective, that's roughly equivalent to 25k people suddenly landing in Hastings [Thread] >> 1

This is the Blood Moon again, but this time 30 6-second images stacked. I think it might have gained a little bit in detail, but I might like the color better on the first one. #Astronomy #Astrophotography

Last night's total lunar eclipse at mid-eclipse. You can tell it is close to the edge of the umbra at lower right. Also called a blood moon if you have orange blood. Takahashi TSA 120, modified Sony Alpha 7 III, 1s exposure moon, 10s stars, ISO 400. #astrophotography

Astronomer Nevil Maskelyne racked up a £141 alcohol bill during his 18 month expedition to observe the 1761 Transit of Venus. That’s over £26,000 ($35,000) in today’s money. Or almost £50 per day. He claimed it on expenses and would go on the become Astronomer Royal. #astronomy #histsci 🧪

The trans women in women's sports thing annoys the fuck out of me because trans women were first allowed to compete as women in the Olympics in 2004. This was the policy for at least 6 summer Olympics, at which not a single trans woman ever won a medal.

🌕➡️🔴 Lunar eclipse alert! Depending on where you are (mostly: Central/Eastern Asia, Oceania, most of North/Central America), you may be able to see a TOTAL LUNAR ECLIPSE ("blood moon") overnight! You can find information about timing and viewing locations here: www.timeanddate.com/eclipse/luna...

Antonio Guterres is up first at this Security Council meeting. He condemns this morning’s strikes by Israel and the US on Iran, and the return strikes by Iran on countries in the region. There is, he says, no alternative to the peaceful settlement of disputes

2. Several prominent outlets falsely reported that the Trade Act of 1974 gives Trump the legal authority to impose temporary tariffs of up to 15% in response to *trade deficits* THIS IS NOT TRUE

The European commissioner for human rights urges countries planning to exercise authoritarian restrictions on children's access to online connection to instead focus on creating safer online platforms that protect children's rights.

and that, my fellow academics, is one reason not to hire war criminals: so they can't show up years post (their) war arguing in favor of the scaffolding behind their own atrocities with the imprimatur and status of your university

Hey, remember that time Gimli showed up at an American Astronomical Society meeting?!

Happy s39th birthday to SN 1987A- the closest to us since the invention of the telescope! 🥳 Always a good excuse to share my cross stitch evolution over time in radio of SN1987A. Everything is to the correct scale etc bc cross stitch is the original pixel art. 🔭🧪 #sciart

Today, Feb 23, is Mount Fuji Day. Recently, there have been several instances where Mount Fuji and fireballs appeared to overlap visually. These are fireballs captured from🏔️Fuji at 4:12 AM on Dec 15,2025,11:08 PM Dec 26, and at 9:05 PM on Feb 1,2026. 📸藤井大地 @dfuji1.bsky.social x.com/dfuji1/statu...

Taught a class on the Protocols of the Elders of Zion today, and every one of my students said they've seen content on TikTok that comes directly from it, without knowing before today what the source was.

If you liked this experiment, I published a full piece today in the same vein: a text that gets 100 years older with every section, from a modern blog post to a medieval chronicle. It's a single story spanning 1000 years of English. See how far you get. www.deadlanguagesociety.com/p/how-far-ba...

Measles is a bellwether. Because it’s the most contagious vaccine-preventable disease, when vaccination rates drop, it’s the first to start spreading. Now we’ve got mumps rolling up. Expect more. This is just the beginning of RFK Jr.’s successful infectious disease reintroduction plan.
