Our panel on RISE-AI is highlighted in this article.

Last week I gave a public lecture at the @AspenPhysics Center titled "How AI Is and Isn't Revolutionizing Science". It was well attended, and I was happy with how it went. Here it is on YouTube: www.youtube.com/live/dIsxqh0...

Some questions I ask whenever I see a crayon like this:

Some of the most fractally romanesco I’ve seen.

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...

🤯“I tasked 16 agents with writing a Rust-based C compiler, from scratch, capable of compiling the Linux kernel. Over nearly 2,000 Claude Code sessions and $20,000 in API costs, the agent team produced a 100,000-line compiler that can build Linux 6.9 on x86, ARM, and RISC-V.”

This is a remarkable @nytimes.com split screen: A huge 3,526 word + photos profile on Sen Britt who "can't stop thinking about the boy ICE detained" But Rep Jaoquin Castro- who actually got Liam Ramos out of detention & back home- gets no interview, no pix, just 116 words inside a story. WOW.

February's ML4MI seminar features Dr. Ulugbek Kamilov, @uwmadison.bsky.social Engineering, who will present score-based methods for computational imaging problems. This seminar will be held in person on 2/16, 11am, at WIMR 2409, with a Zoom option available. ml4mi.wisc.edu/learning-opp...

I woke up before 4am to leave Denver to join this meeting in Madison. Currently at O’Hare. Uff

Sold out show! aspenphys.org/event/how-ai...

It's always frustrating to me how the term AI has evolved. AI was an umbrella term from 1950s. Then Machine Learning (a subset of AI), Deep Learning (a subset of ML), and modern generative AI (a subset DL). Now LLMs are used synonymously with "AI". So I made these graphics of the "AIroboros"

On Feb 9, Jonas Arruda and @alex-andorra.bsky.social will give a live demo on diffusion models for SBI using BayesFlow. Don't miss out! www.linkedin.com/feed/update/...

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

Arrived Aspen Physics Center @aspenphysics.bsky.social . I’ll give a public talk on Wednesday. Very happy to see our Neural simulation-based inference result in the with if the Higgs boson being highlighted ( @sandesarajay.bsky.social )

This is quite the text.

Whoa… 9 years ago, @glouppe.bsky.social and I teamed up with @kyunghyuncho.bsky.social on what I think was the first paper to make a connection between language modeling and particle physics. It also had a cool tie in with intepretability arxiv.org/abs/1702.00748

What a confusing sign. [NO] RE-ENTRY how can the no be optional, doesn’t that change the meaning significantly?

Come join our team!

40 years ago I was in Cape Canaveral to watch the Challenger launch. It was delayed and we had to leave to return to Arkansas. When I got out of the plane I saw the news that it had exploded. It was a lot for an 8 year old

Great memories from 2016! Photo with @glouppe.bsky.social

RIP Gladys Mae West, a US mathematician best known for her foundational work on GPS systems. At @springernature.com we remember her every day as a major communal space in our London offices is named after her 🧪 www.nature.com/articles/d41...

Attention folks in the weather, climate, disaster, wildfire, and Earth science communities: NSF has just published a new "Dear Colleague" letter inviting feedback (by Mar 13) on the proposal to dismantle the National Center for Atmospheric Research (NCAR). www.nsf.gov/funding/...

Remember last week when there were people dismissing the idea they could do illegal things to mess with elections? Days later the administration is using violence from federal agents in the streets as a tool to try and access voter data.

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...

The new NSF public access policy adds software to what must be publicly shared, and must be described in the data management and sharing plan (DSMP) www.nsf.gov/policies/doc...

I’ll be visiting UIUC for an NCSA colloquium and physics seminar on Feb 11 & 12.

UW–Madison ranks 5th in the nation for funds invested in research activities. This is @uwmadison.bsky.social's highest ranking since 2014. news.wisc.edu/uw-madison-5...

Very happy to kick off this new working group on data centers @uwmadison.bsky.social

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:

Photo by Pierre Lavie. Yes this is me. And I threw my Leica. It landed on the bass plate with hardly a scratch. Another Photographer grabbed it along with my phone and I was able to track him later. I was held face down tear gas deployed right in front of me and pepper sprayed directly into the eye.

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.

Cool new paper from my colleague @jsellenberg.bsky.social @uwmadison.bsky.social Math + collaborators. They used AlphaEvolve to generate interpretable programs that led to the discovery of new mathematical structures in the symmetric group arxiv.org/abs/2601.01235

Facebook parent Meta has reached nuclear power deals with three companies as it continues to look for electricity sources for its artificial intelligence data centers.

Been working on this one for a while — it's a little bit of history of a key foundation of internet technology, and a little bit of an explainer about how people _actually_ invent things. This is the amazing (true!) story of how Markdown took over the world. www.anildash.com/2026/01/09/h...

This figure captures how challenging the #cryoEM analysis was, but it doesn't capture the challenges we had to solve in molecular biology, biochemistry, purification, and functional testing. Every step was hard! So glad to see it available.

The Corporation for Public Broadcasting has been dissolved, ending its 58 years as the primary funder for PBS, NPR and local TV and radio stations

New website updates with new group, project, and media pages. Having a blast doing these updates with Claude code and Pelican theoryandpractice.org/collaborator...

UW-Madison is looking for a new Chief Research Administration Officer: jobs.wisc.edu/jobs/chief-r... @uwmadison.bsky.social

I'm spending too long playing around, but I'm having fun. New publications page built from a new pelican-plugin I made with Claude Code. Uses a BibTeX library and some yaml config to make the page, which is served statically from GitHub Pages. theoryandpractice.org/selected-pub...

2025 was a huge year for me and the Data Science Institute. I tried to capture some highlights in my year in review (and updated website) theoryandpractice.org/2025/12/year...

I migrated my somewhat janky / customized pelican3.7 website to pelican4.11 using Claude Code. Migrated to a clean repo, streamlined GitHub Pages deployment, new features! theoryandpractice.org/2025/12/migr...

Update... 3D travel "Worldline". Something I've wanted to visualize for years. It makes this automatically from a folder of images. GitHub: github.com/cranmer/trav... Gallery: theoryandpractice.org/travel-map/

ok, for fun I asked Claude Code to make me a tool where I can drop in some photos from my travels and have it make me a travel map. Thinking about my year in review.

A bipartisan group in Congress formally pushed back against administration plans to dismantle NCAR, while the country experiences a record warm Christmas week with monthly records - and CA braces for more serious flooding and wind (and eventually snow). More: tinyurl.com/3b2tsp7m

Over the last few days I was playing around with claude code. I uploaded a photo of a board game my family plays and had it build an RL environment, a UI, and do some reproducible analysis of strategies with MyST markdown. github.com/cranmer/cass... theoryandpractice.org/cassville-ch...

This is not just "NCAR boosterism," folks. There are multiple empirical measures by which this is correct--and also, if you took a random sampling of atmospheric & Earth scientists from around the world, I'd bet that a substantial majority of them would agree. NCAR is truly irreplaceable.

The LHC community has had more than an exabyte of data and simulation globally distributed, but now @cern.bsky.social has hit an exabyte of experimental observations at its data centers. At these scales, analysis of data from the HL-LHC upgrade will require new approaches. home.cern/news/news/co...
