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.

The world is a dangerous place for intersex people, and new research shows that many feel it’s getting worse

🚨📰📣Breaking physics news! In October, the Circular Electron–Positron Collider (CEPC) study group completed its full suite of technical design reports. However, CEPC will not be considered for inclusion in China’s next five-year plan (2026–2030). 1/3

The Circular Electron–Positron Collider (CEPC), a 100-km electron–positron “Higgs factory” proposed in China, has reached the technical-design stage but will not be included for approval or construction in the country’s 15th Five-Year Plan (2026–2030). cerncourier.com/a/cepc-matur...

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!

The new CERN Courier looks ahead, to the future of particle physics - and back to the outstanding year of 1964. The story of quarkonia spans all six decades, and its final chapter is now being written. Plus: data preservation, X17, dark energy and more. cerncourier.com/p/magazine/

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!

I’ll spend my next week at Helgoland, celebrating 100 years of #quantum mechanics on Heisenberg’s legendary eureka island. If you’ll attend the conference as well, come shake my hand! 🧪🔬🔭

Just found this (Italian!) YouTube breakdown of Laws of Physics by physicist @davidedebiasio.bsky.social on his channel Spazi Attorcigliati. He dives into the first 20 pages—ontology, nomology, laws as constraints. I'm honored! Thanks to #ChatGPT I could follow along! www.youtube.com/watch?v=UDBD...

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.

What if the universe hides a tiny extra dimension just a few micrometers across? How may string theory shape the world we observe? Where shall we look for experimental signatures of quantum gravity? 1/4

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.

Took a while to go through this material. Highly recommend reading even just his papers with 1000+ citations. A phenomenal legacy. On first meeting him as starry eyed grad student remember wondering where the bodyguards were 🧪⚛️

I don't know if the European leaders will stab #Ukraine in the back. I do know, however, that no one will force me to call ‘peace’ an agreement that neither restores the country's legal borders, nor punishes war criminals. Peace is such only when it's just.

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

On my 🇮🇹 YouTube channel (luckily for all non-speakers!) I'm hosting a weekly commentary on the Feynman Lectures on Physics. Each session lasts over two hours, with explicit calculations and digressions into contemporary research. The audience's passionate response fills me with joy – and hope! 🔭🧪🔬

I strongly advise you to go follow the ISQG official profile!

Can we chop the world forever? Will there come a time, in our shift from cells to molecules, atoms, and particles, when reality will reject our attempts to dissect it? Is there a point beyond which the concept of ‘part’ loses any meaning? youtu.be/4LPBZerOcpA 🔬🧪⚛️🔭 #physics #science #quantum #bit

So... What do the 'cancel culture is bad' people think of the latest developments? All I hear is an unsurprising silence. If anyone needed proof, free speech was never the point. Never.

Authors if you see this, it's a sign to post the first line of your book. "The night tore with a whistle, ripped open by Tupoc’s blows. Shreds of bark flew against him. He spat. With the free hand, he wiped his face—slick with sweat, gnats, and splinters of wood."

Authors if you see this, it's a sign to post the first line of your book. "In 1449, an Italian humanist named Francisco Filelfo wrote excitedly to Filippo Pelliccione, a physician in Milan, asking him, indeed begging him, to be allowed to borrow ‘a very ancient book’ in Pelliccione’s possession."

At @stsucl.bsky.social I spent a wonderful year learning about the interplay between science, society, history, and culture – while sharpening my science communication tools. Plus (as you can see from their post), they are way kinder than I’d deserve!

“We can tell whether we are happy by the sound of the wind. It warns the unhappy man of the fragility of his house, hounding him from shallow sleep and violent dreams. To the happy man it is the song of his protectedness: its furious howling concedes that it has power over him no longer.” Adorno
