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

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.

Fox News: "I've gotten my hands that AG Bondi said she sent to Gov. Tim Walz. It is strongly worded. The AG calls for the governor to support the men and women of ICE, to repeal the state's sanctuary policies, and to allow the DOJ to access state voter rolls."

I’ll be visiting UIUC for an NCSA colloquium and physics seminar on Feb 11 & 12.
Illinois is renowned worldwide as a hub of scientific research, education, and innovation.
It’s in no small part thanks to the work being done here at the UIUC’s National Center for Supercomputing Applications.

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

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.
