And yet, the contributions of those working to improve and distribute it, bringing it up to the standards of the accelerators to come, struggle to be recognised. For the latest issue of the Courier, I spoke with Jos, Thomas Gehrmann, and Joshua Davies upon the release of FORM version 5.

One billion proton pairs collide every second in CERN's flagship particle accelerator, flying off at almost the speed of light. FORM is crucial in predicting the outcomes of these extremely high-energy events.

Davide De Biasio @davidedebiasio.bsky.social · 12/03/2026

It was about twenty-five years later that Jos Vermaseren, on the hunt for a more sophisticated and portable tool, wrote the first version of FORM.

Thus he created Schoonschip, one of the earliest computer algebra programs. Written in the nowadays obscure assembly language, only maintainable by Veltman himself, and with a name chosen to "tease the foreigners", Schoonschip could handle the 50.000 terms for the quadrupole moment of the W boson.

That time, though, the formulas were too long. Even assuming one could reach the end, the odds of a plus turning into a minus, or a term slipping between lines, were close to a hundred percent. Not to mention the hassle of fetching thousands of blackboards.

In the 1960s, Dutch physicist Martinus Veltman had a problem: checking that certain particle models wouldn't yield silly infinities. That's the sort of puzzle theorists normally crack with blackboards and chalk, along with large cups of coffee.

“The campaign for intersex people’s human rights has come a long way in the past two decades… Unfortunately, as this research shows, it is still dangerous to be born this way.” Politics aimed at enforcing binary sex result in harmful interventions on intersex people. We must resist such politics.

Working at the CERN Courier is a great honour, and I am deeply grateful for it. This time, we had the pleasure of wrestling with the history of quarkonia, the X17 anomaly, ATLAS's confirmation of a top-antitop excess, and much more. I hope you'll enjoy our latest issue!

I jumped on board as the train was shooting past at supersonic speed, but working on such a significant issue is a honour I struggle to capture in a post. Go and read the new #CERNCourier – before I get too emotional!

One hundred years ago today, Werner Heisenberg wrote to Wolfgang Pauli of radical ideas about quantum mechanics. As this special anniversary edition of #CERNCourier shows, a century has not sufficed to fully understand or apply the theory. Read it now: cerncourier.com/p/magazine/

The CERN Courier has been the high-energy physics magazine for almost seventy years. On a smaller scale, it has been my personal, essential source of information on the field. It is thus with great pleasure that I announce I have joined it as an Associate Editor. I’ll do my best!

Davide De Biasio @davidedebiasio.bsky.social · 07/06/2025

Dear Professor Chen, I’m pleased and honoured to see this post! This discussion is part of a foundations of physics physics I’m delivering on a weekly basis – and I think there’s no better place to explain why “laws” are interesting than your introduction!

One hundred years have passed since Werner Heisenberg, recovering on the Helgoland island, had the epiphany that allowed him to formulate his new science. To celebrate this anniversary, we will retrace the path that led many physicists to believe that every measurement branches reality.

Davide De Biasio @davidedebiasio.bsky.social · 24/03/2025

When you flip a quantum coin, there is a copy of you that sees heads and one that gets tails. It's a bold, radical proposal. Maybe, enough to grasp what physics suggests about the nature of the universe.

Davide De Biasio @davidedebiasio.bsky.social · 24/03/2025

Hugh Everett, while searching for the meaning of quantum mechanics, was confronted with a reality that split and proliferated endlessly. He realised that each experiment has the power to create as many worlds as are its possible outcomes.

Davide De Biasio @davidedebiasio.bsky.social · 24/03/2025

How many parallel worlds are there out there? How many copies of you, living almost identical lives, are reading these very lines? How can we answer such questions?

I am surprised and saddened that hundreds of students graduate from QFT courses thinking that renormalisation is a trick and having no idea what an EFT is.

The great challenge of nuclear disarmament is to move from "many" to "none" without passing through "few". It is an almost impossible task, but our very survival depends on it. We must find a solution. 2/2

A world where many possess nuclear bombs is tragic and dangerous. Yet, one in which only a few have them - and wield that power to subjugate, dominate and exterminate with impunity - is even worse. 1/2

Let me be clear: there wasn't a single instance in which Elon Musk displayed a sound grasp of physics – despite pretending otherwise. He was a charlatan long before his Nazi era.

Do you know how sick you get when Elon Musk opens his mouth on history and politics? Well, that's how physicists have felt for years. The man is the biggest bluff of the third millennium, a mishmash of Reddit threads and clickbait YouTube videos. Now, with a fresh sprinkle of neo-Nazism.

It has to do with the history of pan-Slavism, with a delusion of Euro-Asian domination, with the trauma of those who lived under Soviet rule, with the complex relationship between the former Warsaw Pact countries. It's an ancient, brutal, European story. 5/N

To deduce from the reliance on American aid that a dream of independence rooted in the history of Central and Eastern Europe is a US plot signals deep imperial thinking. It's a sick Cold War legacy obscuring the plain truth. 3/N

Like most resistance movements, it sought help wherever it could find it. Europe lagged behind: it was inconsistent, slow, and psychologically subjugated to the tsar, despite having skin in the game. I would have liked Europe to do more, to be self-sufficient. Sadly, this did not happen. 2/N

I'm ready to die on this hill: the Ukrainian resistance is one of the clearest examples of modern anti-imperialism – and should be treated accordingly. Seeing Ukraine as a ‘proxy’ is not only anti-historical, but deprives an entire people of agency, desires, and aspirations of freedom. 1/N
