This tray is part of the CMS MIP Timing Detector (MTD), to be installed around the Tracker for the Hi-Lumi LHC upgrade. With ~35 ps time resolution, it will help CMS maintain event reconstruction accuracy even with 5x more collisions. 🏆MTD Image of the Month.📸A. Benaglia

The idea that you have to push against something to accelerate is one of the most common misconceptions.

How can Superman blowing air into a black hole create any push? A black hole is a void—what would the air even push against?. #DumbWriting.

What project would you be happy to devote 50 years of your life to, despite (or because of) it only being 10% done when you die?. Ht @hannu @gwern and Antoni Gaudi for inspiring the question.

In Germany, international students can study physics tuition-free because public universities are funded by taxpayers. Since universities receive the same funding regardless of nationality, they have no financial incentive to admit more or fewer international students, nor to use.

If Universities didn’t take international students there would be *fewer* places for ‘smart kids from Wisconsin’. International students subsidise these places. This sounds like someone who hasn’t ever thought about their position for longer than 3 seconds.

Cool paper!. It's interesting that it's limited to dimensionless variables. Does this suggest it performs better for physical systems that can be described by only dimensionless quantities?. I wouldn't be surprised if that is connected to the fact that it finds different sets of.

Absurd, ridiculous story, but if dumb emails are presented as the ‘War on Science,’ any scientist reading this will see it as completely out of touch with the reality of massive budget cuts gutting entire research programs.

From a Dean to his faculty at McGill U. Can it get much dumber? Sent to me by a faculty member there who was incredulous. The kind of nonsense pervades university administrations as we discuss in The War on Science, available July 29th.

Can an AI model predict perfectly and still have a terrible world model?. What would that even mean?. Our new ICML paper formalizes these questions. One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧵

In Berlin, a friend told me about a map that was circulating of East and West Germany, illustrating how individual generational wealth was far greater in the West—a supposed testament to capitalism's superiority. But as my friend pointed out, what the map left out was that in.

Grok 4 is the first time, in my experience, that an AI has been able to solve difficult, real-world engineering questions where the answers cannot be found anywhere on the Internet or in books. And it will get much better.

I would really like to know if there's anyone who seriously believes it's wise or sustainable for the entire UK university system to be so financially dependent on international student fees. And if nobody wants this system, why do we have it?.

Visa applications to study in UK slip for first time in 2025. There were fewer international student visa applications in June 2025 than in the same month in 2024, marking the first year-on-year fall in six months.
