Congratulations to the class of 2025! 🎓🎉@brownphysics.bsky.social

A beautiful @cmsexperiment.bsky.social event to kick off 2025 data taking at the @cern.bsky.social LHC!

Tomorrow's lecture in my class is about pitfalls to avoid when designing figures -- quite a fun topic to prepare! 🧪

Honoured to learn that I -- alongside >13k of my close colleagues from @cern.bsky.social's @atlasexperiment.bsky.social, @cmsexperiment.bsky.social, @lhcb.bsky.social and ALICE Experiment -- was awarded the 2025 Breakthrough Prize in Fundamental Physics! Congrats all! breakthroughprize.org/News/91

Do you want to learn more about the @cmsexperiment.bsky.social at @cern.bsky.social? Join the virtual visit starting in ~20 minutes on youtube to get a live tour of the detector cavern and have your science questions answered! 🧪🔬→ www.youtube.com/@CMSExperiment

… and today, another @ippog.bsky.social masterclass! With six high school classes, we discussed proton structure, jets, and how AI intersects with particle physics. It was a treat to moderate the VC with one of @atlasexperiment.bsky.social’s most ‘heavy metal’ physicists, Martin Rybar!🧪🔬

I was happy to host an @ippog.bsky.social particle physics masterclass VC today! High school students from Poland & Greece compared LHC data analyses, and asked about life working at @cern.bsky.social. 🧪🔬 We discussed positive impacts of HEP on society, incl. medical technologies like PET scans!

A most wonderful letter 🧪 Looked too perfect to be true, so I checked the source (einsteinpapers.press.princeton.edu/vol8-trans/34) - it is true! Originally in German. Additional historical context by @mariapopova.bsky.social here: www.themarginalian.org/2016/04/19/e...

I once again want to plug one of the 'simple tool' websites I use the most when prepping #physics talks and lectures: www.unicodeit.net, made by @svenkreiss.bsky.social and Kyle Cramner. I don't even know how to open the equation editor on my computer, and I hope that I never will! 🧪

I took advantage of the holiday weekend to get some lecture prep done, and clearly made the most of it. 🧪

I always enjoy learning about the efforts to photograph large-scale experiments like Dune -- not only was this was a great read, but the photos are amazing! Like a sci-fi movie, only real! 🧪📸

Getting ready to teach some Modern Physics this term … 🧪

me: "my father was a fisherman; now I teach people about fission!" my physics class:

The original @cern.bsky.social x Lego collab? 🧪 From the cover of the July-August 1975 CERN Courier: "[...] a 3D representation of the data from a recent search for charmed particles."

Getting ready for the kick-off event for CERN’s 70th anniversary this year, a set of discussions about art & science. You can follow along online here! www.youtube.com/live/JNPnrfQ...

Today is my first day as research faculty at Brown! Getting settled in, need to next bring in some books and plants … 📚

Snowy lunch at #CERN today! ☃️

I had a great time at DESY this week learning about the bleeding-edge of AI in particle physics at #ML4Jets2023! Many thanks to the organisers @GregorKasieczka, @freyablekman, & all for their hospitality! 🔬🎉🤖🧪

The ATLAS Experiment always takes particle physics into uncharted territories — Hi Bluesky! 👋

Saturday morning hike in Zermatt ... ⛰

Complex particle jets at the LHC lend themselves to AI algorithms 🤖, which can distill lots of info into accurate decisions. This week, @ATLASexperiment presented 4 new results about jet tagging w/ AI at #BOOST23! 🎉 You can learn more here: https://atlas.cern/Updates/Briefing/Boosting-Jets-AI 🧪

Getting high-quality signals w/o noise from pile-up is one of the biggest experimental challenges at the #LHC. We're improving @ATLASexperiment reconstruction in #Run3 w/ timing information⏰ and #AI🤖, presented this week at #BOOST23! learn more: https://atlas.cern/Updates/Briefing/Signal-Noise 🧪

#BOOST23 is happening this week! I'm at @BerkeleyLab talking about jets, substructure, QCD, AI/ML & more with experts from theory & experiment! @ATLASexperiment is showing many new, jetty results 🎉 -- you can find them summarized here! atlas.cern/Updates/News/Sum... 🧪

Arrival in California 🌴🌺🌁

It was a lot of fun to work on a search again! We didn't see any significant 4-jet resonances in the @ATLASexperiment Run 2 data, but if we had, it could have looked something like this. You can read about this search today on the @arxiv : https://arxiv.org/abs/2307.14944 (🎉🎉)(🎉🎉) 🧪

Finally at home for long enough to see the hibiscus blooming -- two at once today! 🌺🌺

bluesky is the great equalizer

@danirabaiotti.bsky.social could you add me to the What's Science list? I'm a particle physicist working at the Large Hadron Collider.🧪

On Twitter, I mostly followed scientists: here, I hardly follow anyone. So, scientists, please introduce yourselves and share your best STEM follows (of all stripes)!

It was a treat to talk about a photon & multijet measurements from the LHC at #SMatLHC 2023 today! Although I couldn't go to @Fermilab, hopefully I still illuminated the many results of @ATLASexperiment & @CMSExperiment from afar.💡🎉🔬

Evidence that people have made it back to CERN from the Vancouver ATLAS Week.

Good morning from #CERN! I'm a scientist studying quarks and gluons with the #ATLASexperiment, to learn about the #StrongForce and search for new particles. You can expect: 🎉 The latest results with jets ☕️ Slice of life around CERN ❌ Next to nothing about the 90s sitcom #Friends (wrong guy)
