Over the next three months, scientists expect to make the world’s most precise measurement of the muon’s anomalous magnetic moment, often expressed as the quantity g-2.
In 1991, James Cronin travelled to Leeds, England, to visit Alan Watson, an expert on cosmic-ray physics. Cronin, a Nobel Prize winner in physics who had worked on accelerator-based particle physics experiments, wanted to discuss ideas for cosmic-ray projects.
Look at the periodic table of elements, and youd be hard pressed to find an element that is not used in physics. But what are the most important elements for building accelerators, detecting particles, and solving the mysteries of the universe?
The spotlight caught Todd Satogata. The camera zoomed in. “Did your particle beam shoot down a UFO?” the TV host asked. The accelerator physicist at RHIC, Brookhaven National Laboratory's Relativistic Heavy Ion Collider, smiled. Of course not.
You can't feel it. Yet the moon's gravitational pull shifts the ground ever so slightly, creating “earth tides” that rhythmically raise and lower the ground.
