`The Lense-Thirring effect, a prediction of general relativity, implies that massive rotating objects like Earth can slightly "drag" spacetime, which could affect the pendulum's oscillation. This effect, though theoretically significant, is currently too small to measure with a Foucault pendulum.`

I don't remember hearing about this before, but the #FoucaultPendulum at the #SmithsonianInstitution in #WashingtonDC, was removed in 2008, and there are no plans to re-install it, ever.

I don't know about you, but the Foucault pedulums at the #FranklinInstitute in Philadelphia and at the #Smithsonian are two of the things that inspired me to pursue #Science.

It upsets me to know that it was removed and won't be reinstalled.

Dang, if I had kept recording for another minute I would've had film of a peg being knocked over.

Galileo had a 10m long pendulum outside the window of his office at Padova University. He observed that the period of the oscillations were almost independent of their amplitude and proposed to use it as a speed regulator. (1641)

The Foucault pendulum installed in Palazzo della Ragione allows to observe the rotation of Earth but the rotation of it's oscillation plane is slower than the Earth's (265⁰ per day).
