Physical exercise

摘要

Physicists who dream of tracking down the building blocks of matter or of unravelling some of the secrets of string theory have their eyes on Switzerland. Construction of the Large Hadron Collider (LHC) is nearing completion at CERN, the European particle-physics lab near Geneva. Smashing subatomic particles together at unprecedented energies, the giant facility will offer physicists the chance to gain a deeper understanding of the early Universe. Particle physics today needs more power — physically and analytically — than ever before. "New accelerators don't come online very frequently these days, and the LHC s size alone makes it important," says Per Osland, secretary for the European Physical Society's high-energy particle physics board.
