Some science cuts in Trump's proposed FY27 budget

❌ NIH: -$5B, including all of NIEHS, NIMHD, FIC & NCCIH.
❌ EPA: -4.6B
❌ NSF: -3.8B
❌ NASA Science: -3.4 Billion
❌ NOAA: -1.8B, including the entire Oceanic and Atmospheric Research budget ($605M)
❌ AHRQ: All of it. -$296M, 100%

And there's more.

If there is one thing I’ve learned is that if a project is struggling, adding a bunch of new trainees always helps, especially if they’re being paid and you’re not, and they’re the reason you’re not being paid

Excited to have @thserra.bsky.social here at UW Madison for SILO seminar series.

#MOS

I am expecting you to start with a joke next week. 😀

You’re on fire!🔥

Any more misleading than having an empty BOUNDS section in your MPS file and having the lower bounds of your variables be 0?

I wouldn't blame scipy. Default lower bound of zero has been the convention of LP since the dawn of LP.

And no SDP, even better! 😵‍💫

I come to Bluesky for all my Optimization and Sewing news.

This is an intriguing paper with numerous examples of using an LLM to generate formal proofs and ideas, and a nice cookbook for how to do it. Refreshingly, the paper stays away from hype and as far as possible states very clearly how the LLMs are used and the key nature of human-AI interaction.

Oh no. This is so sad. We all were at Georgia Tech together. Kelly was wonderful. Heartfelt condolences to Todd. :-(

So much for the Provost search.

Wait wut?!?!?!?

Backing PDHG into a Corner Recent enhancements to the Primal-Dual Hybrid Gradient (PDHG) algorithm have enabled GPUs to efficiently solve large linear programming problems, often faster than the long-dominant simplex and ...

This is an amazing work.

I was there too. But I was in Grad School. 😜

I’m an award-winning mathematician. Trump just cut my funding. The “Mozart of Math” tried to stay out of politics. Then it came for his research.

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

The Irrational Decision How the computer revolution shaped our conception of rationality—and why human problems require solutions rooted in human intuition, morality, and judgment

I’m excited to announce that my new book, _The Irrational Decision_, is now available for pre-order from Princeton University Press.

FICO Xpress Optimization Surpasses AlphaEvolve’s Achievements FICO’s global optimization solver outperforms Gemini AI-powered AlphaEvolve coding agent by improving solutions for complex, constrained math problems

Weeping with joy.✌️

Three things made the US a rich and powerful nation: the rule of law, its science & innovation system, and openness to foreign talent. Remarkable how Trump has taken a sledgehammer to all three. No enemy of this country could do more.

Please erase!!!

If a foreign adversary snuck into our Federal budget and cut science research and education the way we’re cutting it ourselves — strategically undermining America’s long-term health, wealth, and security — we would likely consider it an act of war.

This is a great thread on a great blog post.

“I can…assure you that were this a Republican president…targeting Democrats, I at least would speak out just as vigorously against it because if we are going to respect rule of law, the apparatus of the federal government cannot and should not be used as a partisan tool to bludgeon your enemies."
