What is a period of restlessness for many of us can be turned into a time of reflection and learning from the safety of our homes. What better way to do that than with a healthy diet of physics-themed videos? 1/n #StayAtHome
Let's start with John Ellis. We thought it's time to finally figure out what the Higgs boson is... 2/n #StayAtHome
Watch the unlikely story of our most venerable accelerator, from the mouth of our most venerable coworkers ⤵️
🔭Discoveries made during the past 20 years have revealed the impressive diversity of extrasolar planetary systems.
Watch this CERN Colloquium by Michel Mayor, who is co-laureate of the 2019 @NobelPrize in Physics along with Jim Peebles and @DidierQueloz.
"I... a universe of atoms, an atom in the universe". - Richard Feyman. Let's travel to your universe!
Who remembers the Large Electron-Positron Collider, which was operated by CERN from 1989 to 2000? If you don't, time to get a refresh. It is, after all, the largest electron-positron ever built.
Until we can hop back onto our bikes outside, #StayAtHome. In the meantime, let's cycle back to 2019 when our bold co-worker raced accelerated particles around the LHC.
If you have a training bike at home, you can even pretend #confinement is over...and imagine you are riding inside the LHC! (not quite as steep as Mt Ventoux 😏)
Ever wonder about the colour of antimatter? Find out more about the light spectrum of antihydrogen here ⤵️
Learn more about the ambitious and accomplished @ALICEexperiment and practice your French with today's video! (English captions available 😉)
With the current situation, works for the #HiLumiLHC are on an extended break. We all look forward to resume this beautiful project. Until then, #StayAtHome!
👁 Sure, a field trip to CERN would have been nicer... But in these exceptional times, a 360° virtual tour of CERN's experiments is the next best thing we can offer.
Today, visit the @CMSExperiment and #StayAtHome! (filmed last year before lockdown)
And this, folks, is how you make #antimatter!
Please don't try this at home.😏
The electric field has its electron, but when it comes to the magnetic field, have you ever heard of a #magneton?
🤔 Where has all the #antimatter gone? If this question prevents you from sleeping at night, rejoice! For the @LHCbExperiment is there to quench your thirst for knowledge.
🛤 Discovering the Higgs particle and field was far from being the end of the journey. Studying its interaction with other particles is crucial to understanding how they acquire mass.
Protons may be in the spotlight at CERN, but neutrons shall not be forgotten. By studying their properties, the #n_TOF can help in dealing with various issues like nuclear waste management or cancer therapy.
Let yourself go, with François Englert's explanation of the Standard Model equation... We didn't understand everything at first either 😏
🌌 If you thought that protons, neutrons and electrons were the only guests in the vast zoo of particles, think again! Today, we're looking at the NA62 experiment, which chases the elusive kaons and their decays into pions.

#OnThisDay in 1902, the theoretical physicist Paul Dirac was born.
As we #FollowTheProtons to CERN’s #Antimatter Factory, what better way to start than by celebrating the work of this young physicist and his @NobelPrize-winning equation?
@NobelPrize In 1928, Dirac wrote an equation to describe the behaviour of an electron moving at a relativistic speed. It could have two solutions: one for an electron with positive energy, and one for an electron with negative energy.
@NobelPrize This equation, in some way, predicted for the first time the existence of an anti-world identical to ours, but made out of antimatter.
What would you ask him about antimatter if you could meet him? 🎂
On 13 July, CELESTA was launched into #space aboard #VegaC.
Here are the quick facts:
🛰️ It is the first CERN-driven satellite
🤖 It will study radiation's effects on electronics
🤝🏽 It is a collaboration with @umontpellier
Protecting satellites against radiation is a challenging and costly task. Some of CERN’s facilities are able to reproduce the environment of Earth’s orbit at a low cost, and help with radiation testing: kt.cern/aerospace/faci…
To study the effect of space radiation on electronics, CERN has developed a radiation monitoring device, Space RadMon, taken into space with the #CELESTA microsatellite aboard #VegaC.
Display of a collision event recorded by ATLAS on 5 July 2022, when stable beams of protons at the energy of 6.8 TeV were delivered to ATLAS for the start of #LHCRun3.
Display of a collision event recorded by CMS on 5 July 2022, when the collisions at the record energy of 13.6 trillion-electronvolts (TeV) were first recorded by the #LHC experiments. #LHCRun3
Today’s #PhotoOfTheWeek is all about the @LHCbExperiment. We are almost ready for #restartingLHC, so here are some of the tasks involved in the upgrade of the LHCb experiment. 💪
@LHCbExperiment ✅ Upgrade of the VErtex LOcator, a detector used to determine the exact point where the particles collide. One of its sensors is just 5mm away from the beam. Brand new modules were installed, with 40 million active pixels.
@LHCbExperiment ✅ New mirrors for the ring-imaging Cherenkov (RICH) detectors: this system consists of two huge digital cameras that measure the speed of particles. The lens system of the cameras is made of about 200 flat and spherical mirrors immersed in special gases.
“I would like to express my deepest gratitude to the many partners in our Member and Associate Member States and beyond who are making the #CERNScienceGateway possible, in particular to our generous donors.”
Fabiola Gianotti, CERN Director-General
“We will do our best, not only in the construction & operation of the #CERNScienceGateway but also more widely to ensure that science maintains a place of integrity and trustworthiness, of international collaboration aiming for peace”
Ursula Bassler, President of the CERN Council
