Origins of the Ising model

In 1925, Ernest Ising published a paper analyzing a model proposed in 1920 by Wilhelm Lenz for ferromagnetism. The model is composed of constituent units that take only two states and interact only wh...

Big grant news today! I feel very lucky and honored for this opportunity from @erc.europa.eu . We will attempt to go for a big qualitative step up in how we use AI/ML to predict how particles interact with matter. Stoked to get started on this in 2026. we will release job advertisements soon!

The researchers conducted an empirical study comparing an LLM to human programmers comprehending clean and confusing code.

Based on their analysis, both LLMs (via LLM perplexity) and humans (via EEG) are similarly confused about the code.

How do Humans and LLMs Process Confusing Code?

Thanks Ken, it's an interesting analysis and i am super happy that experts like yourself (or Marek/Jan-Ake's group yesterday arxiv.org/abs/2508.19207) are spending their time helping us clarify and improve the ideas. We are discussing your paper internally and will certainly come back to you.

...leaves open loopholes for local-realistic models, it is possible to modify our measurement scheme, using a CH inequality, to get a 'unquestionable Bell theorem', and our experimental quality should already allow for its violation.

Super exciting paper by the groups of Jan-Åke Larsson & Marek Żukowski (two top-experts in Bell's theorem):
arxiv.org/abs/2508.19207

They analysed our recent paper on a very strange nonlocal interference effect (science.org/doi/10.1126/...).

They found that while the inequality we used ...

Last year, a team identified 47,176,870 as the fifth “busy beaver” number, a quantity tied to one of the hardest problems in computation. They've now found that the sixth number is so big, it's impossible to write without special notation. www.quantamagazine.org/busy-beaver-...

The quest to find the longest-running simple computer program has identified a new champion. It’s physically impossible to write out the numbers involved using standard mathematical notation.

This year quantum physics turns 100, so @nature.com decided to conduct the biggest ever survey of what lies behind it. Do physicists really believe in multiple universes? Can influences happen instantaneously? Is the Copenhagen interpretation all it's cut out to be? ⚛️🧪 www.nature.com/articles/d41...

Physicists disagree wildly on what quantum mechanics says about reality, Nature survey shows

First major attempt to chart researchers’ views finds interpretations in conflict.
