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.
Physics has demonstrated that the everyday phenomena we experience are governed by universal principles applying at time and distance scales far beyond normal human experience.
The sighting of Jupiter's moons by Galileo Galilei resonates through science and history. Using a handmade telescope in January 1610, Galileo confirmed the Copernican theory that the planets moved around the sun; the Earth was not the center of the solar system.
Along the Loop Road at Stanford Linear Accelerator Center, the roar of falling water and a refreshing mist filled the air after six solid weeks of California rain. But the water cascading down the inside of Campus Cooling Tower 101, and landing in a frothy pool, is hardly scenic.
Neutron scattering research has improved the quality of many everyday items: Shatter-proof windshields, credit cards, pocket calculators, airplanes, compact discs, and magnetic storage tapes are just some examples.
Over a half-eaten burrito or a bowl of spaghetti, Sam Ehrenstein ponders the unanswered questions of fundamental physics. Yet Sam is no experimental physicist or postdoc brooding over his data. Not yet, anyway.
After undergoing a buffered chemical polishing (BCP) treatment at Cornell University, the first US-processed and tested International Linear Collider superconducting cavity achieved a milestone accelerating gradient of 26 MV/m (megavolts per meter)–surpassing the first gradient goal (25 MV/m).
Welcome to SLAC's End Station B, where work on the International Linear Collider (ILC) will help shape the future of particle physics–although some inhabitants don't seem to give a hoot.
