Description	Journal: Physics World The first Foucault's pendulum I ever saw was at the Franklin Institute in Philadelphia, the city where I was born. The pendulum hung in a stairwell. Its wire was attached to the ceiling four stories up, while its silver bob glided silently back and forth over a globe in the floor, with Philadelphia at dead centre. The plane of its oscillation slowly shifted clockwise at an unchanging rate throughout the day: 9.6° an hour. I'd stare at it, trying to make myself see it was the floor and I that moved – as the sign informed me – and not the pendulum itself. It troubled me that I was never sure I succeeded.
