Secret of the hidden ledger

When exploring the mysteries of the universe, don't neglect the floorboards. Last December at Fermilab, repairs to the ceiling over the kitchen in the Aspen East users' center, targeting a joist that had distorted the floor of the dorm room above, produced some startling debris.

Into a new world of physics and symmetry

The worldwide particle physics community is about to sail on a voyage into a New World of discovery. The Large Hadron Collider, a multi-billion-dollar particle collider that will begin operations in Europe in 2007, will take us into new realms of energy, space, time, and symmetry.

CERN cafeteria

Walk into the main CERN cafeteria at various times of the day and you'll find different scenes: scientists discussing results over coffee; a parent coaxing his children to finish lunch before swooping them back to the nursery school on site; groups of grad students soaking up the sun on the

Extracting physics from the LHC

A proton travels around a 27-kilometer ring at nearly the speed of light. Along with a bunch of other protons, it passes through the hearts of each of a series of detectors more than ten thousand times per second. Then, on one pass, it slams into a proton coming from the other direction.

The United States and the LHC

The United States has contributed the energy and expertise of hundreds of scientists and engineers, and more than half a billion dollars to the construction of the LHC particle collider and two of its experiments at the European laboratory CERN.
