@wellingmax very cool! for MD, what would you say are the main advantages wrt to traditional software such as LAMMPS or GROMACS?

Preprint alert!

In this work we present quantum-mechanical calculations of permeances of graphdiyne for the transport of hydrogen, comparing with molecular dynamics simulations and taking into account the membrane's thermal motion.

First time! 😀

Yep, math is going to be 'solved' in a few years everyone

Is there some kind of bet going on where everyone is trying to post the most unhinged opinion about physics and math at the moment?

At university, you realize that:
1. many students are dumb
2. you’re not particularly smart either.

A few thoughts after reading the @OpenAI paper on scattering amplitudes over the weekend:

- The result from GPT-5.2 Pro is technically impressive, clearly at the level of a strong grad student / postdoc

- However, without the transcripts, it is unclear what role the human authors had in producing the final result. For example, what materials was the model provided with: previous papers, internal notes, Mathematica? In its current form, the claim in the paper that "the key formula (39) for the amplitude in this region was first conjectured by GPT-5.2 Pro and then proved by a new internal OpenAI model" is basically unverifiable :(

- I think journals should start requiring authors publish their transcripts with AI tools. Reproducibility is a core feature of the scientific method, and referencing secret models that the broader community doesn't have access to is deeply unscientific IMO

This video should unsettle anyone who takes the United States seriously as a nation.

Because it exposes something dangerous: the trivialization of the world's most consequential office. It shows how carelessly the power, credibility, and accumulated moral authority of a superpower can be squandered for a few seconds of viral attention.

In any other major democracy, this behavior from a head of state would trigger a constitutional crisis. Paris would burn. Berlin would convene emergency sessions. In the Nordic countries, resignation would follow within hours. Across functioning democracies, the public, institutions, and political class would recognize this for what it is: an assault on the dignity of the state itself. Leaders are not free to perform as entertainers without consequence. National honor is not personal property, it's held in trust.

But the United States is not just another country with a provocateur in charge. It is the linchpin of global order. It maintains formal alliances and security guarantees with forty to fifty nations. It underwrites the financial architecture, trade systems, and diplomatic frameworks that billions of people depend on daily. When the American president speaks—or posts—it doesn't land as satire, meme, or personal whim. It reads as a signal about what the country is becoming.

American power has never relied solely on carrier strike groups or economic output. It has rested on something more fragile and more valuable: trust. The belief that beneath domestic turbulence lies institutional seriousness, predictability, and a baseline commitment to dignity. That belief is now disintegrating in real time.

Millions of American companies operate globally. They negotiate multibillion-dollar contracts in environments where reputation is currency. Boardrooms in Frankfurt, Singapore, and Dubai aren't debating whether a post was clever—they're asking whether the United States remains a reliable partner. Whether agreements signed today will be honored tomorrow. Whether American leadership has devolved from institutional to purely theatrical.

Consider tourism, which sustains millions of American jobs—airlines, hotels, restaurants, museums, entire regional economies. Soft power isn't an abstraction. It materializes in flight bookings, conference locations, study-abroad programs, and decades of accumulated goodwill. A quiet, decentralized boycott doesn't require government action—only a collective sense that a nation no longer respects itself.

Now picture this image being studied by foreign ministers, central bank governors, defense strategists, and sovereign wealth fund managers. Picture them asking a coldly rational question: How do we write binding thirty-year agreements with a country whose public face will be this, relentlessly, for years to come? How do we plan for the long term when the tone is impulsive, mocking, and unbound by the gravity of office?

This is where the real calculus begins. Trillions in foreign capital depend on confidence that America is stable, credible, and rule-governed. That confidence is now being traded for what, exactly? Applause from an online mob? A dopamine rush from manufactured outrage? Content designed to dominate the news cycle rather than serve the national interest?

Every serious nation eventually confronts this choice: burn long-term credibility for short-term spectacle, or safeguard the reputation previous generations bled to build. The United States spent eighty years constructing an image of reliability, restraint, and leadership under pressure. That image wasn't born from perfection—it came from a visible commitment to standards that transcended impulse.

This isn't a partisan issue. Europeans who value democratic norms recognize something ominously familiar here. Americans—Democrat and Republican alike—who believe in responsibility and restraint should see it too. Power attracts scrutiny. Leadership demands discipline. A superpower cannot behave like a reality TV contestant without paying a price.

The presidency is not a personal broadcast channel. It's a symbol carried on behalf of 330 million people and countless international partners who never voted but whose lives are shaped by American decisions anyway. Every post either reinforces or erodes the idea that America can be counted on when it matters most.

So the question is no longer whether this is offensive. The question is whether this is who America chooses to be: a nation that trades a century of hard-won reputation for viral moments. A country that replaces statecraft with content creation. A republic governed like a season of reality television.

History offers a harsh lesson here. Great powers don't fall because enemies mock them. They collapse when they begin mocking themselves—publicly, proudly, and without grasping the cost until it's far too late.

In November 2024, environmental police in Rochedo, Brazil, stumbled on an unexpected sight: thousands of orange-and-black bumblebee catfish scaling the slippery rocks behind waterfalls on the Aquidauana River. A week later, a team of Brazilian scientists arrived to document the unprecedented event, detailing their findings.

These videos provide rare insight into the lives and migrations of these little-studied catfish, the authors said. This genus of small South American fish, which inhabits the rocky bottoms of fast-flowing streams, only became known to science in 2017.

They nuke Harvard's funding, which everybody told them was going to lead to Chinese research dominance. China is now dominating and instead of reconsidering their terrible science policies, they're blaming it all on minorities.

These people are insane.
