As CERN’s 60th-anniversary year comes to an end, CERN Courier gives a voice to some of the organization’s pioneers who are no longer with us. Extracts from audio recordings in CERN’s archives bring to life the spirit of adventure of the early CERN. One of the studies that CERN pioneered was the measurement of the “g-2” parameter of the muon – an experiment that in its latest incarnation is setting up in Fermilab. The year also saw the 50th anniversary of the International Centre for Theoretical Physics in Trieste, and an interview with the centre’s current director reveals interesting similarities and contrasts between the two organizations. The end of the year also offers the traditional seasonal Bookshelf. Happy reading! To sign up to the new-issue alert, please visit: http://cerncourier.com/cws/sign-up.
