Hello to those who found me here. I am a particle physicist at CERN working on the @lhcb.bsky.social experiment and on future accelerators. In particular I worry about sustainability.
I'm also chairing the advisory committee of the 12000 CERN users.

In the Portuguese presidential election, very clear victory of the centre-left candidate Segura against the radical right Ventura.

Reading a preprint that has an indent at the beginning of each section and no indent at the start of a new paragraph. I can't.

I was discussing Wu's non-nomination at @nikhef.bsky.social last week. I did know she wasn't nominated in 1957. But then she got plenty of nominations later. ⚛️

Chien-Shiung Wu shattered one of physics' core assumptions. ⚛️
In 1957, she proved that nature does distinguish between left & right in weak interactions.
Before her, physicists thought mirrors didn't matter in fundamental laws.
She flipped that on its head.🧪

Many people have wondered why the Chien-Shiung Wu never won the Nobel Prize for Physics. New findings from the Nobel archives, exclusively revealed in Physics World, show she was nominated 23 times by 18 different physicists - and yet was still left empty-handed. 🧪⚛️

Profoundly sad to read news of Roger Barlow's passing. A great physicist, educator and communicator, who lived by his principles and would share his wisdom with anyone who asked. The world is now a poorer place.

Every unit of sunshine that hits earth is precisely $0.
It’s literally insane that we know that fact and allow a profiteering scheme to tell us that’s not good enough and charge us for an alternative that literally kills us.
