Around the world

Travel is an integral part of the life and work of particle physicists. Since the beginning of the year, some 30 physicists known as the Quantum Diarists have criss-crossed the world to meet collaborators at distant accelerators, attend conferences, teach a seminar, or interview for jobs.
