Christophe Salomon and the measurement of time: the transition to atomic time
Parution dans la presse
For centuries, mankind has been trying to master time with ever more precise clocks, today achieving a drift of just one picosecond per day. How have cold atoms made it possible to refine this measurement, and what's the point of such a quest for precision?
