A Reuters photographer captured this image of a page from Pam Bondi's "burn book," which she used to counter any questions from Democratic lawmakers during an unhinged hearing today. It looks like the DOJ monitored members of Congress’s searches of the unredacted Epstein files. Just wow.

For reference, building 8-12 new beamlines at NSLS-II over the next 12 years or so is also about 500M$

Alberto Castañeda Mondragón was hospitalized with eight skull fractures and five life-threatening brain hemorrhages. Officers claimed he ran into a wall, but medical staff doubted that account. n.pr/4bHoZDU

GM: Charisma check. Mamdani: [rolls natural 20] GM: that’s a d6 how did you Mamdani: [direct to camera] Did you know you can check out board games at your local public library? 😊

Angus just gave a FOSDEM 2026 talk on Introducing Jupyter Book 2 and why this stack matters for reusable, reproducible computational publishing. 2i2c.org/blog/fosdem-...

Appalling news. @ukri.org has some serious questions to answer. How was prioritisation made and how is UK's world leading international science programmes being tensioned against national facilities?

The Factbook survived the Cold War and became a hit online. It mixed quirky cultural notes and trivia with maps, data, and photos taken by CIA officers. But it was discontinued this week. n.pr/3Mq3Y6i

We're excited to announce Pixi GUI, developed by our working student Felix Häcker! With the goal to make Pixi accessible to a wider audience while also empowering expert users. Find out more in Felix's blog post: prefix.dev/blog/introd...

The @uwssec.bsky.social team wrote up why they switched to Pixi for all their research software engineering: "Pixi has allowed us to remove the friction of package management to focus on what matters: writing better, reproducible scientific software." prefix.dev/blog/seeking...

1. It was not an accident. 2. It was not a staffer. 3. While the president may have dementia his racism is not due to dementia. 4. He isn’t sorry. He means every racist thought he shares. 5. His base agrees with him. 6. He will do it again. 7. No one in power will hold him accountable.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

Just like with Kilmer Abrego Garcia, the biggest sin any targeted immigrant can commit is winning battles — legal or PR battles — against the government, and they just won’t let those losses go

“It seems our university leaders cannot even say that it is wrong to murder a former student in broad daylight because some people might disagree,” geography professor Kate Derickson

I will be giving the Nick and Maggie DeWolf public lecture at the Aspen Center for Physics tomorrow. See, it’s in the newspaper. @aspenphysics.bsky.social

Scaling Laws in Particle Physics Data! This is a result I've been itching to share and it's finally out. One of the big open questions is how much better AI-based methods at particle colliders can still become. 1/4

How many STEM Ph.D.s were lost from the U.S. federal government last year? My colleagues @mghersher.bsky.social and @policyhound.bsky.social dug into a recent data release to find the answer. A @science.org exclusive. www.science.org/content/arti...

There have been 3 homicides in Minneapolis this year. Trump’s agents committed two of them: a mom and a nurse who cared for our Veterans. Stay the hell out of our cities.

This moment in history provides us with incontrovertible evidence that all the conservatives who claim to be extremely devoted to freedom of speech and the right to bear arms, and opposed to the encroachment of tyranny, are completely and totally full of shit. It's all white supremacy and greed.

Alex Jeffrey Pretti was an ICU nurse at a VA hospital. His life, through his profession, was dedicated to serving his community and our country. As so many have now seen on video, his final act before he was killed by federal agents was doing everything in his power to protect his community.

A state government is having to file an emergency lawsuit to be able to ensure that the federal government is not actively obstructing justice.

You all know I’m their biggest critic. Credit to @nytimes.com for reporting the truth and not the criminal regime’s lies this time. www.nytimes.com/live/2026/us...

“One officer responded mockingly as he walked away, telling (protesters): ‘Boo hoo.’” apnews.com/article/immi...

ICE agents will continue to execute our citizens in the streets for as long as they believe they can get away it. There will be more executions like this. What are our leaders doing to prevent it?

Walz: "We sill investigate this. We will not be stonewalled ... this will end when enough American say this will end. Do I have any confidence that Donald Trump will do the right thing? No ... quit referring to these people as law enforcement. They are not law enforcement."

A coworker took this from her apartment. I haven't seen a crowd this size before. Maybe the first Women's March? But it was much much warmer that day. ICE OUT OF MINNESOTA!

As clergy pray, arrests begin

I talked with the Director of Quantitative Analysis for the @ladodgers.bsky.social yesterday. They are looking for physicists that have experience analyzing data, uncertainty quantification, and deep learning. Two jobs: recruiting.ultipro.com/LOS1000LADOD... recruiting.ultipro.com/LOS1000LADOD...

🗓️ SciPy reminder: Just over a month left to submit! The CFP submission deadline is February 25. If you’re working on a talk, tutorial, or poster, now’s a great time to start polishing and get ready to submit to your favorite conference! 🚀 ➡️ Submit here: pretalx.com/scipy-2026/cfp

New — I wrote about ChongLy Scott Thao, the elderly Hmong American wrongly arrested and forced out of his home by ICE in his underwear during the punishing Minnesota winter, what witnesses saw, and DHS's racist claim that he fit the description of another Asian man they were looking for. My story:

Entertainer, childhood literacy advocate, and *scientific philanthropist* Dolly Parton was born #OTD in 1946. Mostly known for singing and songwriting, Dolly's Imagination Library program has distributed over 100 million free books to kids around the world. 🦋 📖 🎶 dollyparton.com/imagination-...

They’re investigating everyone except the murderer.

Mubashir and his family came to the United States as refugees from Ethiopia when he was a child, and they all became naturalized citizens in 2019. Despite being a U.S. citizen, Mubashir was targeted by ICE, assaulted, and detained. Listen to his story:

Let’s call this what it is: a disgusting abuse of power and a farce. As his agents terrorize Minnesotans, as prices rise, as he fails to deliver for Americans, he is also weaponizing the DOJ against his perceived enemies. This is not a banana republic and justice will prevail.

“Noem: U.S. Citizens Should Be Prepared To Show Proof.” Did you vote for a “Show Me Your Papers” society?

Reminder if you find yourself somehow running out of space on your multi-TB laptop to check your ~/.cache size. I got 150 GB of disk back today by doing some trivial cleanup. ``` du -ch ~/.cache | tail -1 | cut -f1 ``` Caches are wonderful things and having large caches on large disks is great!

Laser Loon forever!

Excited to receive my copy of the second edition of Maxwell Dashwood and Christopher Hendon’s Water for Coffee! This book has been long awaited and I’m looking forward to learning much more about water chemistry beyond the little bits I have so far from making my own coffee water at home.

HT @simonegiertz.bsky.social for this framing, but if you can afford Netflix you can afford to support @npr.org. The US needs a free and independent public media. I've started an annual recurring donation to the network and I would encourage you to do so as well. www.npr.org/donations/su...

The US Department of Agriculture suspends all federal funding to Minnesota, effective immediately.

Tried to do Higgs production via gluon-gluon fusion on my cappuccino. Messed it up pretty badly but I think to make it more viable I should try with a larger cup and so a latte. Would be fun to learn how to really nail some Feynman diagrams on demand. :)
