Thermodynamics has a missing law. We spotted it. 📷

Free energy governs work extraction. But only one process at a time.
We asked the device-level question.

New preprint:
📷 Quantum work beyond classical (commuting) limits

One device. Many preparations. Many Hamiltonian settings. We derive the exact classical average-work limit when "classical" means only that the Hamiltonian settings commute. Incompatible Hamiltonians exceed it.

Every branch stays free-energy bounded. 📷. The resource isn't extra work in one process.
It's Hamiltonian incompatibility across the task. 📷

[The Nobel Prize @NobelPrize]

This year’s chemistry laureate Omar Yaghi was born in Amman, Jordan, in 1965 to parents who were refugees from Palestine. When we spoke to him he shared his story:

“I grew up in a very humble home, we were a dozen of us in one room, sharing it with the cattle that we used to raise. I was born in a family of refugees, and my parents could barely read or write. My father finished sixth grade and my mother couldn’t read or write. It’s quite a journey. Science allows you to do it. Science is the greatest equalising force in the world.

Smart people, talented people, skilled people exist everywhere. That’s why we really should focus on unleashing their potential through providing them with opportunity.”

Today Yaghi shared the 2025 Nobel Prize in Chemistry with Susumu Kitagawa and Richard Robson for their work developing metal–organic frameworks.

Lately I've been seeing a lot of hype around quantum computing on this platform. Are those bots or humans? Either way, what I'm seeing is concerning. I want to provide an honest perspective on the current status quo, which is hopefully useful. Long story short, I do think a lot of exciting progress on QC will be made over the next few years. But I doubt those progress will be commercial applications.

India prioritized the concerns of the upper caste/upper classes, over that of the masses. Pretty simple really. India didn't aspire to build basics first, it aspired to go to space like the Americans and Russians.

Ok, here we go: Much of my work concerns the history and return of scientific racism. I’ve written extensively about attempts to resurrect the shuffling corpse of
race science and eugenics for many years. Bigotry dressed up as biology. 1/n

Been thinking a lot about hiring and @soumitrashukla9’s paper finding that discrimination is alive and well in elite hiring.

Soum finds the bulk of discrimination against lower-caste job candidates emerges after amorphous, subjective “personality fit” interviews.

Following allegations of names being deleted from the SSB awards list for non-scientific reasons, a group of Indian scientists have written to the Principal Scientific Adviser seeking clarification on the selection process for SSB awards.

Ashoke Sen, Deepak Dhar, Shubha Tole, Mahan Mj, Vidita Vaidya are some of the signatories.

This is the letter.

Piracy isn't okay. It's good see illegal sites like KimCartoons shut down. If you actually want to support these shows legally, go watch them on their official streaming service or live TV.

RCT introduction of a pollution market in Surat, Gujarat.

Pollution fell by 20–30%, and efficiently — gains came from the firms who could cut pollution most effectively.

Mortality benefits are *25 times* costs.

An incredible state/research collaboration.

@tamilravi Data exists in the Indian context as well.

Job applicants with a Dalit or Muslim name were significantly less likely to be invited for interview than equivalently-qualified high caste Hindus.
