De laatste run van de Large Hadron Collider (LHC) op CERN is begonnen. Aan het eind van deze periode gaat de LHC voor vier jaar uit bedrijf voor een grote ombouw.

Such a cool way to show people the β€œinvisible” microscopic world whizzing around them! βš›οΈπŸ§ͺ

πŸ’₯Splash! πŸ’₯

CMS sees splashes of protons in the detector: beams of protons are whizzed around the #LHC and crash into a barrier just before the CMS detector! We use these splashes to calibrate the detector before starting full particle collisions, due to take place in the coming days.

Halvemaansteeg & Rembrandtplein, Amsterdam in 1979 and today.

From car-choked streets with little space for people to a lively car-free area with only trams, pedestrians & bikes permitted. Cafes and outdoor seating dominate the area.

A reminder to politicians: design streets for the city you want.

Hoe gaat het eigenlijk met ITER? We missen Marco de Baar hier op BlueSky, maar net even wat foto’s bekeken en het is echt indrukwekkend. Klassieke: β€˜big science megastructure’ 🀩

Funding U-turn will cost UK trust and leadership, partners say.

Senior European physicists say country’s status as β€œreliable partner” damaged by withdrawal of pledged investment.

On my way to University of Twente.. why is it always so cold when I’m lecturing about High Energy Physics?

I understand the angle here, but I wouldn't want people to think that all this furore is just about LHCb. STFC plans to cut particle physics and astronomy research in the UK by 30%. That means one in three researchers risk losing their jobs. One in three university groups may close. Serious shit.
