Such a good Nobel Prize! Francis Halzen is a great person, and “let’s turn the Antarctic ice sheet into a neutrino detector” is the kind of idea that deserves a Prize if you can pull it off.

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2026 #NobelPrize in Physics to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.”

LLMs could be the end of the “shut up and calculate” approach to fundamental physics. (Not that Kyle is part of that.) When the computer is better at calculating than you are, you might be forced to actually think about things.

Wow, I just found out that our team has been scooped by Anthropic www.anthropic.com/research/yes... See the addendum of the post “How does it feel to be scooped by a machine?” written by my collaborator Lance Dixon (who was under NDA while checking the result)

"Boltzmann Brains" is a fanciful name for a dead-serious idea. I'm beginning to wonder whether the name hasn't caused the physics community to not spend nearly enough time thinking carefully about the problems that they pose. We have Boltzmann Brain Blindness. Long 🧵 coming. ⚛️ #cosmology (1/n)

Math proofs online, physics research accelerating—as much as could be said about any period in history, this really does feel like a pivotal moment for humanity. I’m just glad to be alive.

An old fable for Dualities in Physics: Once, a group of blind men were asked to describe an elephant. As they reached out to touch it, the one who felt the trunk said it was a snake. Another touched the body and said it was a wall. But in reality, they were all trying to describe the same thing.

The paradoxical nature of our world has led to many discoveries and here’s one that’s still unresolved: The laws of quantum mechanics are perfectly reversible, yet the world we experience is irreversible. 0/7

As I near 5th yr of PhD in Physics, I reflect on lessons beyond eqns, papers & prob-solving. It has taught me patience, humility, resilience & comfort with uncertainty. If you’re considering PhD in fundamental science, I hope this aids honest entry with less fear. 0/5

We have created a world with previously unimagined material abundance, and yet we have organized society such that many people struggle with loneliness and alienation. Now we're offering tools that enhance delusion and paranoia. www.404media.co/delusion-usi...

Researchers Simulated a Delusional User to Test Chatbot Safety

Grok and Gemini encouraged delusions and isolated users, while the newer ChatGPT model and Claude hit the emotional brakes.

Remembering the innocent lives lost in the Pahalgam terror attack one year ago today. We stand with the families who continue to carry this loss. As a nation, we remain united against terror, unwavering in our resolve.

Full house at @pattersonparkhtx tonight. I had so much fun talking about: Are we living in a Matrix! A big thank you to @after5society for the invite and organising this and a bigger thanks to each and everyone who showed up. Cheers 🥂

Mathematicians call prime numbers the building blocks, analogous to atoms. I find this weird. In physics, building blocks have a smaller scale associated with them, while prime numbers are at the same “scale” as all other numbers. How do you think about this?
