Altro punto di vista sul lancio di Artemis II, quello di una telecamera montata direttamente sul razzo. Nel video si vedono anche i due booster laterali (Solid Rocket Boosters, SRB) nel momento in cui si separano dal corpo centrale, seguiti dalla fase...

I will never not be angry at the way tech bros have told us that the danger is apocalyptic superintelligence when it was always obvious that the reason to worry is that we would put dumb AI in really stupid places.
I see advanced LLMs more similar to very knowledgeable but ruthless students, at the moment. A "philosophical" physicist would not be able to really supervise such a student on a computational project.
What argument does Trump now have against Putin? None whatsoever. And it's becoming clear he doesn't even want one beyond narrow self-interest.
Welcome to the nineteenth century.
You can tell that LotR was written by an academic because Gandalf disappears for like 20 years doing research to answer a single question.
I honestly don't understand why any European institution, EU-official, decision-maker of an EU member country etc. is still posting on X. It's owner literally campaigns for your destruction, despises your values and rules and you still provide his platform with reach and relevancy? Anybody home??
Editor searching reviewers in August
Since search is dead, how soon do you think Google Scholar is headed for the Google Graveyard? I'm betting it's soon, and academia is NOT prepared

Here is the preprint:

This research was driven by the excellent work of Christian Apostoli and Jacopo D'Alberto and our fruitful and always fun collaboration with Marco G. Genoni and Davide E. Galli.
* Unprecedented accuracy: Maintains high fidelity even in complex, highly entangled regimes, within the flexibility of the variational approach.
* Massive parallelism: Double Monte Carlo sampling of configurations and of trajectories.
What does this mean for researchers?
* Drastic reduction in cost: Slashes the computational resources needed for large systems.
In our latest work, we introduce a new method that unravels master equations into quantum trajectories, solved using a stochastic time-dependent variational Monte Carlo approach.
Schematic representation of the otVMC method. Open quantum system dynamics is unreveled in quantum trajectories, and each trajectory is evaluated with the stochastic time-dependent variational Monte Carlo method
New preprint!
Simulating the dynamics of open quantum systems is a major computational bottleneck, largely due to the exponential scaling of density matrices. We're tackling this challenge head-on. 🧪
Butterfly meme: a physicist looks at any physical system and asks "Is this a harmonic oscillator?"
Our SPS group circulated this:
Fearing yet more war;
hoping for peace.
May war-mongering leaders be removed, and innocents everywhere be safe. What else is worth saying?
My students' final essays are due tomorrow. Lol.
The Helgoland 2025 quantum mechanics centenary meeting kicked off last night at the rather grand Hotel Atlantic in Hamburg, with a dinner followed by historical talks.
Quantum tunnelling may be common at the tiniest scales, but no one had ever observed the phenomenon in fluorine - the element was simply thought to be too heavy. Now, this accepted wisdom has been upended in new experiments that observe fluorine tunnelling

These are real images of exoplanets.
Four super-Jupiters, imaged 10 times over 12 years around a star 133 lightyears away.
These are real, giant worlds, out there in the dark.
And we can see them.
Git was 20 years old this week. Written by the creator of Linux as a tool to streamline his workflow - it shows the importance of making tools. If you have a better way of doing something, write and share it. It's possible that few others understand the problem, let alone have the solution you do!

We just need to turn the negative productivity of scientists at NASA and IRS auditors that DOGE fired to gainfully making shoes in Nike factories reshored from Vietnam.
This is the groundbreaking economic thinking of communist purges from Mao to Pol Pot with a sprinkle of American Exceptionalism.
Explaining to young men that outsourcing your thinking to LLMs is bad because reading and writing is like lifting for your brain
