People are often using AI to increase the seeming complexity of minimal ideas, where I find I spend most of my time taking highly complex ideas and compressing them as much as possible into minimal descriptions. Can AI do that? I would say not.

It’s times like these that remind me of Asimov’s Mule. And an interesting question about how far we can go beyond probabilities in looking ahead with social behavior.

2026년 가을부터 서울대학교 물리학과에 조교수로 합류하게 되어 매우 기쁘게 알립니다!

저에게는 새로운 장이 될 것이며, 학과에서 이미 진행되고 있는 놀라운 연구에 새롭고 복합적이며 다양한 기여를 더하게 될 것입니다.

마지막으로, 이러한 혼란스러운 시기에 민주주의와 법치주의를 수호하는 젊지만 활기찬 문화를 포용하는 곳으로 가게 된다는 것을 말할 수 있어 안도감을 느낍니다.

새해를 앞두고 미리 건배합니다! 🥂

@Neon_sci I'm noticing that a lot of the SCBI precip data is blank when I download the data. Does anyone know what's up? NEON website claims all the data should be present.

Finally got around to read Darwin. The clarity of thought is wholly impressive and still compelling today.

Also very quotable and perhaps one of the reasons this work became such a recurrent tome.

This is nuts
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

A fun read about group selection on culture, not genes 🧪
What changes when humans change: individuals with genes, or groups with culture?

In this month's Q&A, I talk with @twaring.bsky.social about his argument that humans are going through an evolutionary transition: groups are the new individual, and culture is the new genome. 🧪
The individual isn't what it used to be
Tim Waring thinks human evolution is shifting from genetic and individual to cultural and collective

Last month's Q&A with @spintheory.bsky.social dug into the ~physics~ of polarization in the US Senate and what it has to do with the simple neural network models that sparked the AI boom:
Politicians talk big. But what if (with a bit of physics) you could let their votes speak for themselves?

In this Q&A, I chat with @spintheory.bsky.social about what his mathematical maps of US Senate politics reveal about polarization — with a surprising link to the physics foundations of AI 🧪⚛️

🍁A call for PhD positions in complex systems relevant to ecology
#Ecosystems, #ecology, and #forests as an example are marvelous examples of #complex systems. In collaboration with our colleagues at BOKU, we are also interested in applicants who want to study these topics! Applications due soon!

🧪🦋🌳
Ready to tackle the world’s most complex challenges?
We are looking for #PhD candidates eager to apply large-scale data analysis, quantitative models, and complexity science to shed light on pressing global issues.

Highlighting this Simons postdoc fellowship again. Looking for junior postdocs who might team up with Brian Enquist and me.

Keywords include nonlinear dynamics, reaction diffusion, population dynamics, metabolic scaling.

🧪🦋🌳
This is a great Simons foundation #postdoc opportunity for theorists with incipient interest. If you’re interested in working in quantitative laws of life in ecosystems, please message me.

Due date Dec. 4.

Note the 3 years w/in PhD condition.

One of the most fascinating points from the Q&A:

Polarization isn't just about what we believe. It's about what we choose to make into a political issue.

Some issues divide, others unite. The Senate is voting on more polarizing issues and, predictably, getting more divided outcomes.
@spintheory.bsky.social used statistical physics to study 50 years of #Senate votes, and accidentally recreated the network architecture that won the 2024 Nobel in Physics. He finds #polarization is more complex than R vs D. Read the Q&A with @elisecutts.bsky.social 👉 shorturl.at/TD3bN
