Liebe "PiA - Physik im Advent" FreundInnen, nur noch 10 Tage bis zum Start von "PiA - Physik im Advent". JETZT anmelden: www.physik-im-advent.de Bitte informiert auch Eure FreundInnen, Lehrkäfte, Nachbarn ... #Physik #MINT #Bildung #DigitaleBildung #Adventskalender #Advent #Schule #Lehrer

Happy #PrideinSTEMDay! 🏳️‍🌈🏳️‍⚧️ ATLAS proudly celebrates the incredible diversity of our scientific community. Our varied backgrounds, perspectives and identities drive excellence in research. We are committed to advancing the recognition and representation of our LGBTQ+ colleagues — today and every day.

Es geht wieder los mit der Reform des #WissZeitVG! Der letzte Versuch ist geplatzt, weil die 🚦 auseinandergeflogen ist. Aber: Seitdem liegen aussichtsreiche Lösungen für das Kernproblem Postdoc-Phase auf dem Tisch! Wie lassen sich Befristungen in dieser Phase eindämmen? 5 Instrumente: ⬇️ #IchBinHanna

Heavy-ion season is here! 💥⁠ ⁠ The ATLAS Experiment at @cern.bsky.social has recorded its first lead-lead collisions of 2025, marking the start of three weeks of heavy-ion running at 5.36 TeV per nucleon pair.⁠ Take a look at some of our first spectacular event displays!⁠

Es geht wieder los mit der Reform des #WissZeitVG! Diesmal muss es was werden, faire Bedingungen überfällig: Was ich 2023 gesagt habe, gilt weiterhin! ⬇️ @drkeichhorn.bsky.social, @kubon.bsky.social & ich haben uns in der letzten Runde intensiv für #IchBinHanna eingesetzt, werden’s auch diesmal tun.💪

Students, apply for a CERN summer studentship. Greatest experience ever! Deadline 26 January 2026. careers.cern/programmes/s... (It's not just for physicists. Check it out.)

Last part of the 2025 LHC physics programme has just started. We will take 3 weeks of heavy ion collision data before going to a short end of year break in December.

Was fun to see so many friends and colleagues on the big screen 😃 Not sure when and where "the peace particle" movie will be screened for a wider audience, but I can definitely recommend it.

Zählt so ein Social-Media Gig zu den Höchstbefristungszeiten nach WissZeitVG? #IchBinHanna

Die aktuelle Ausgabe des Physik Journal der DPG illustriert einen Artikel mit einem offensichtlich KI-generierten Bild - natürlich ohne Quellenangabe oder sonst irgendeinem Hinweis. Peinlich und vollkommen überflüssig.

Vor 10 Jahren habe ich am CERN eine Schülerpraktikantin im Rahmen des Netzwerks Teilchenwelt betreut. Vorhin kam die Ankündigung für ihr Promotionskolloquium in meinem Postfach an 😊

🎤 Are you passionate about science? Show us! 😉 To mark the 20th anniversary of FameLab International, CERN is teaming up with FameLab to invite you to share your love for science and win fantastic prizes.

"Es war nicht eine kleine Zahl von Verbrechern, es waren Hunderttausende einer sogenannten deutschen Elite, Männer, Jungen & entmenschte Weiber, die unter dem Einfluss verrückter Lehren in kranker Lust diese Taten begangen haben." Thomas Mann 9. November 1938

Amateurs 😄 The @atlasexperiment.bsky.social has to detect particle collisions every 25ns (40MHz). Then our first level trigger system has about 2.5 microseconds to analyse and decide whether to keep each of these events and pass it to the second level trigger before the buffers overflow.

In honor of the upcoming #WomenInPhysics Day, let's create a thread of amazing women physicists. I'll start with one my favorites, Chien-Shiung Wu, who is best known for conducting the Wu experiment, which proved that parity is not conserved. ⚛️ 🧪 👩‍🔬 🎢

POV: Preparing to investigate the mysteries of #DarkMatter 🌌 In honour of #DarkMatterDay, we accompanied Baptiste, an @atlasexperiment.bsky.social physicist studying dark matter, as he gears up for his day of detective work.

Let's go on a Dark Matter Hunt! It's almost Dark Matter Day -- also known as Halloween 👻 🎃 -- and I'm really excited to be heading to the STFC’s Boulby Underground Laboratory! This is a unique facility where scientists hunt for the missing matter that makes up our Universe. 🌌

Why on earth needs a scientific publisher like Elsevier a "Director of Generative AI"? Why do we need AI-supported peer review? I want to read about original research not some plausible-sounding made up garbage.

Applying weights of 100% (last), 90% (1st), 50% (2nd) and 10% for anybody else in larger collaborations is wild, especially if the convention is to publish in alphabetical order 🤨

No large particle collider in China in the near future. "CEPC will not be considered for inclusion in China’s next five-year plan (2026–2030)" ⚛️🧪 cerncourier.com/a/cepc-matur...

50000000000000000 proton-proton collisions is a lot of data to analyse. Thanks a lot LHC! To put this in perspective, that should correspond to roughly 30000000 produced Higgs bosons.

ZOOM is broken, this will be an interesting day...

I was interviewed, in German btw, in the context of the #Herkommen project that highlights newcomers in Germany. We talked about international mobility, life as an immigrant, and of course particle physics. Auto-dubbing is available! Or enjoy my Süßes Hollandodeutsch 👼 🇳🇱 🇩🇪 youtu.be/JQqh0lPTsLY?

The Briefing Book for the Update of the European Strategy for Particle #Physics is out! It is a summary of the state and the ambitions of the field, summarising the hundreds of community and national white papers we received as input earlier this year. ⚛️🧪 cds.cern.ch/record/2944678

Had never read Jane Goodall's original 1963 article in Nat Geo on the wild chimpanzees in Tanzania until now. It's a wonderful blend of science and journalism, and well worth your time. www.nationalgeographic.com/pdf/jane-goo...

Here is an entertaining take on all of those anti-science grifters on YouTube and elsewhere. Highly recommended. youtu.be/miJbW3i9qQc?...

The physics institute of the @unibonn.bsky.social hosted the US team of this year's Beamline4Schools at our own electron accelerator ELSA. They measured transition radiation photons using various targets, and I had the pleasure to meet them and chat about physics. What a bunch of smart kids!

Difficult for me to put into words how disappointed I am in Sabine Hossenfelder. Many years back when she was just blogging about physics I was a huge fan, and she published a lot of intriguing papers. Now she makes money as a social media arsonist. 🧪 www.mcgill.ca/oss/article/...

i wrote about atproto and why it matters

If you're looking for indications that US developing following the course of 1930s Nazi Germany, then any indication of ICE widening their mission from detaining illegal immigrants to legal immigrants to groups of people beyond that set is a potential warning sign. 1/

Die Debatte über Charlie Kirk hat gezeigt, wie tief rechtes Gedankengut in der Gesellschaft verankert ist. Wie erfolgreich es normalisiert wurde. Das Verrückte: Vielen ist nicht Kirk und seine Gedankenwelt unwillkommen, sondern die Kritik daran. Mein neuer Essay: „Radikal? Immer nur die anderen!”

One more citation, bro. That's all I need, I swear. Just one little citation and I'm over it, I swear. Everything will be fine. 😉

The inability of too many journalists to point out blatant lies as what they are, is the root problem of our time.

Freitag Morgen, ÖPNV quasi leer. Seid ihr alle wieder im Home Office?

2 Wochen Blockveranstaltung mit Vorlesungen jeden Tag fast geschafft. Heute haben mir ein paar Studierende selbstgebackene Kekse als Dankeschön mitgebracht. Das hatte ich auch noch nicht, hat mich aber sehr gefreut 😊

Got a new temporary office mate. ⚛️
