Features

The quest for gravitational waves

The search for gravitational waves - gravitational perturbations in transit ­ remains a major objective for the start of the next century. But with such a feeble force the waves are extremely difficult to detect amid the cacophony of noise on the Earth's crust.

Making tracks for the LHC

Pictures ultimately provide the most graphic record of of particle interactions. For CERN's LHC collider, sophisticated electronic "eyes" at the heart of the big ATLAS and CMS detectors will pick up the tracks left by the particles fleeing from the collisions and search for masterpieces to hang in the next century's gallery of research art.

Challenging the Big Bang: a longer history of time

Conventional dogma says that the Big Bang was the beginning of everything. Here, Gabriele Veneziano of CERN challenges this view. He believes that the Big Bang is the biggest thing that the universe has seen, but that it did not take place at time zero.

The ratchet of time

New results remind us how, in the strange world of the neutral kaon, a fast rewind does not necessarily take you back to where you started.

Directions beyond the Standard Model

The annual theory workshop at the German DESY laboratory in Hamburg traditionally focuses on a burning physics issue. The latest event, exploring "Directions beyond the Standard Model", tried to peer beyond the physics horizon.

Relic neutrinos, a challenge for the next millennium

Neutrinos created in the first seconds after the Big Bang could hold vital clues about the evolution of the universe. A workshop in Trieste looked at a wealth of intriguing possibilities.

ABSolutely fabulous!

Software is playing an increasingly important role in the tricky business of setting up the beams from particle accelerators. A recent workshop at CERN looked at what has been accomplished so far and what still needs to be done.

ECFA in Poland

In its continual tour of CERN Member States, the European Committee for Future Accelerators (ECFA) visited Poland recently. The venue was Cracow's 600-year-old Jagiellonian University, the oldest institution for higher education in Poland and among the oldest in Europe.

Putting a spin on physics

Both theoretically and experimentally, spin physics has always been a challenge. Although many physicists proudly point to an increased understanding, some spin puzzles are still waiting for an explanation. The biennial Spin Physics Conference is always a good barometer for spin.

The sun sets on SATURNE

After a 40-year career, first as a weak focusing machine and then rebuilt with strong focusing, the French SATURNE synchrotron has exited the physics stage.
