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.

Climate Physicists Face the Ghosts in Their Machines: Clouds | Quanta Magazine The planet is getting hotter, but one factor in particular makes it hard to tell just how hot it will get. Physicists and computer scientists are racing to solve the problem of clouds.

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.

Agree. The recent challenge problems have too much Silicon Valley hype/magical thinking and not enough grounded university/lab scientist vibe for me.

Weird hack

There is a new paper that people are excited about with collaborators from OpenAI that used an internal AI tool to derive a result in theoretical physics. I’m totally distracted by the screwed up metadata in the @arxiv post. How did this get through?

The IceCube Upgrade has been successfully deployed! 🎉

The Upgrade marks the first significant expansion of IceCube since its completion 15 years ago.

A small polymerase ribozyme that can synthesize itself and its complementary strand The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.

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.

Today at 2:00 pm at @ncsaatillinois.bsky.social @kylecranmer.bsky.social will give a colloquia "Emerging Patterns in AI for Science" - see calendars.illinois.edu/detail/598?e...

Physicist @kylecranmer.bsky.social of @uwmadison.bsky.social, who aided in the #Higgs discovery, cautions that not every anomaly matters. “There’s an infinite number of ways the data can look different,” he says. The challenge is finding a “Goldilocks” balance between noise and real physics. (4/8)

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

How AI Is and Isn't Revolutionizing Science with Kyle Cranmer YouTube video by Aspen Physics

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:

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

Some of the most fractally romanesco I’ve seen.

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

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.”

The G.O.P. Senator Who Can’t Stop Thinking About the Boy ICE Detained Katie Britt is uniquely positioned to reason with the Trump administration — when she chooses to speak up.

Representative Joaquin Castro of Texas said in a post on social media that he had picked up Liam and his father, Adrian Conejo Arias, from the Dilley detention center on Saturday night and escorted them to Minnesota on Sunday morning. He shared photos of the two on social media, including one showing Liam at the airport clutching what appeared to be a Pikachu toy and wearing a Pikachu backpack. Mr. Castro was part of a delegation of Democratic lawmakers who visited Liam and his father at the detention center last week, where he said Liam’s father had reported that the child was “very depressed” and hadn’t been eating well since they were detained earlier this month.

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.

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

There are also image generation, audio generation, and video generation models, so LLM doesn’t fully capture it

Sold out show!

Naïvely, I thought you would’ve just counted the number of times each prime appears and normalize. That doesn’t give you a sense of the size of the contribution.

Interesting. Right off the best though you write “So you can think of the proportion of n that is “made of” the prime p_i to be (a_i log p_i / log n)”. I’m a little confused what your distribution is over (primes?) and what probability you are assigning them. Is it the formula above?

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"
