In the hallway of the University of Queensland in Australia, an unassuming little experiment is kept in a glass case. It’s not that interesting, until you know that it’s the longest-running lab experiment in the world, and is just about to turn 100 years old. It’s the Pitch Drop Experiment, and it teaches us a lot about the unseen world of long time scales.
