Foucault Pendulum

When I was a child we would visit the Griffith Observatory from time to time.  I was always fascinated by the Foucault Pendulum
 I still am.  I am not alone, it is a magnet for most who enter the observatory.
As the pendulum moves back and forth, the earth is turning beneath it.  About every 8 minutes the earth has rotated enough that a pin on the bottom of the pendulum knocks over another of the tiles at the left.
The shiny ball of the pendulum reflects the newly restored Hugo Ballin Murals in the dome of the rotunda.

Find more reflections at Weekend Reflections, hosted for us by James.

So glad you chose that as your reflection post and explained it to us. I've never seen such a thing and I am also now very fascinated by it.

I understand you fascination for this pendulum... In Paris we had one displayed in the conservatoire des arts et métiers in Paris for year ; it wasn't as pretty as this one, but it was drawing oscillations in the sand on the ground, and I spend hours looking at it...

I have never been to the Griffith Park Observatory. Next time we stay with my brother, I will propose an excursion. (He will say "where did that come from?")

I saw one of those at an Atlanta science museum last fall. I was fascinated, too.
Happy 2013!
