In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
When objects weighing thousands of pounds have to be moved, the call goes out to riggers— specialized teams that work with hoists and cranes. They’re required to wear proper safety gear; and at some point, the riggers at SLAC decided to make a statement with their helmets.
Theorists cant help it: When asked to explain something, they reach for a piece of chalk. The language of math and physics seems to require a writing implement and a large vertical surface.
The problem: How to get short-lived radioactive drugs from the nuclear physics lab that makes them to a hospital 2.5 kilometers away, on the far side of a busy campus, in two minutes flat.
With a blue marker poised at a large white flip chart, Maury Tigner, a physicist at Cornell University, turned to a group of about 10 representatives from industry and asked, “What kind of applications interest your company?” The room was cramped and beige, a generic hotel meeting spa
It began with a guest speaker in her small upstate New York town. Roshan Houshmand’s uncles were visiting, and because of their engineering background, she thought a talk on physics would be ideal for a night of entertainment.
Chalkboard discussions usually arise spontaneously, with one person explaining something to a small group standing nearby. Scratchings on the board tend to represent fragments of a conversation rather than a complete train of thought.
