Happy to see @msalbergo.bsky.social passing through Madison.

So long #LHC and thank you for all the collisions 👋 Today, the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, comes to the end of an extraordinary chapter in its scientific journey. Find out more: home.cern/cern-bids-fa...

Come be my colleague!

A nice rainbow yesterday!

I really enjoyed these two videos about math and physics of music. The first is about Pythagorean, Just, and Equal Temperament and has a nice explanation of the 2^{1/12} issue I learned about as a grad student. It emphasizes pure math and fundamental note youtu.be/nK2jYk37Rlg?...

CERN leads a project to make EU scientific data more accessible The EU-funded HORIZON-ZEN+ project is developing AI tools to improve the increasingly popular EU Open Research Repository. Find out more: lnkd.in/dXH-RQAZ #OpenScience

This case could be absolutely huge for AI-related law. I don't see why tech companies should get a free pass when they generate harmful material

Core software infrastructure tools like this continue to be incredibly highly sided. Ironically, they’re also often severely underfunded.

WOW - Trump crashes out & cuts his interview w/ Welker short as she presses him on his lack of evidence for claiming elections are rigged "You're either crooked or you're stupid. I've had enough. Thank you darling," he tells her" "I traveled all the way to Wisconsin for this interview," she pleads

I have great memories of this project, which developed from a narrowly scoped question to something much more impactful over more than a year. It’s interesting how terms like “Asimov” and “signal strength” and “mu” now permeate the field.

I'm at a symposium on internal combustion engines (which UW Engineeringhas been doing since 1946!). I was surprised to see Zeldovich show up. Same Zeldovich that was a giant in cosmology en.wikipedia.org/wiki/Yakov_Z...

In 2026, @uwmadison.bsky.social will move from early investment in AI toward broad institutional readiness, centering people, judgment and institutional guardrails. DSI Director @kylecranmer.bsky.social will participate in the AI Readiness and Competency Working Group. news.wisc.edu/uw-madison-d...

I’m at U. Chicago for SciFM26: Foundation Models and AI Agents for Science www.scifmconferences.org/program

Another awesome poster from @annalenakofler.bsky.social and another cool use of simulation-based inference!

State Rep. @jasmineclarkforga.bsky.social wins the Democratic primary in the vacant #GA13, @decisiondeskhq.bsky.social projects. Clark is now poised to become the first Black woman PhD scientist to serve in Congress. My interview with her here: 19thnews.org/2026/05/geor...

I'm very excited about this new paper, which kicks of our LEGO ERC project we started earlier this year towards general-purpose AI surrogates for simulating radiation-matter interaction. Instead of training AI surrogates for specific detectors or material distribution ...

I'm in Hamburg, Germany joining my first meeting as a member of the Scientific Council for DESY sc.desy.de/e7/

K3 surfaces are a fascinating example of spaces that have rich geometry in a multitude of different yet closely intertwined ways: differential geometric, algebrogeometric, 4-manifolds, moduli, fibrations, enumerative… yet they are just simple enough to be accessible. Let me introduce you to the K3!

I've only skimmed so far, but seems interesting, thoughtful, and full of some nice quotes and references.

Tomorrow at 1PM CT: Join the @alliance4dsai.bsky.social for a talk on building and sustaining campus-wide data science and AI research institutes, with Sarah Stone (University of Washington) and Kyle Cranmer @kylecranmer.bsky.social (UW–Madison). Register at zoom.us/meeting/regi...

I loved that in yesterday's announcement "Openness" was literally the first principle that was mentioned: "Landay says Stanford HAI’s defining commitment will be openness: open science, open-source code, open datasets, and open education." news.stanford.edu/stories/2026... @stanfordhai.bsky.social

Nice view of San Francisco this morning.

Before vs. after. The last 6 weeks have been intense

Submitted! 🎉

Take note Wisconsin! @uwmadison.bsky.social is a powerhouse in quantum, but Illinois is way ahead in terms of investment. (Note, quantum does not use big data centers).

A stunning visualization born from a collaboration with @manlius.bsky.social : 55,486 galaxies and 29,555 streamlines tracing how matter flows across our local universe, built on data from the CosmicFlows-4 project. Article in the first reply 👇

I’m thrilled to see the growth of our open source internship (and our new OSPO website). Thanks to support from @sloanfoundation.bsky.social and @warfnews.bsky.social through the RISE initiative

Got caught in a tornado on my drive home from FermiLab. Scary.

Visiting @fermilab.bsky.social to give a “Wine & Cheese” seminar on Emerging Patterns in AI for Science.

It was great to have @tylerjamesburch.com of the RedSox talk about sports analytics! He’s holding a CD with the first release of R signed by the core developers

Later today we will have Alyssa Travitz talking about the role of Research Software Engineering in Molecular Sciences, pharmaceutical, etc.

For April fools day in 2014 I wrote a paper called The Realineituhedron in reference to Amplituhedron. This was one of the figures. In October @QuantaMagazine did a piece connecting the Amplituhedron to origami 😂 theoryandpractice.org/2014/04/The-...

🚨I'm happy to share a preview draft of new paper "Scalars Are All You Need for Multimodal Inference". Instead of the traditional approach to multimodal foundation models for science with task-independent embedding, I outline an alternative strategy theoryandpractice.org/2026/04/scal...

I thought this was pretty funny while on vacation, but realizing that the email is going to find me tomorrow when I go back to work.

Happy to see a Simulation-Based Inference Blueprint workshop being held at CERN. First papers were in 2015, and it took several years to get the first physics papers out. Hope to see it become more mainstream. indico.cern.ch/event/160067...

Climate scientist Chris Bretherton leads a team training a neural network on data from real clouds. Their model is already competing with traditional simulations to make seasonal forecasts.
