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.

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.

Fire-fighting foam

When the CERN safety team and I heard the loud rumbling 25 meters underground, we weren't concerned. With no warning, it would have been frightening, but the rush of water through pipes overhead presaged a thrilling event.
