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.

Nice photos, great for the theme!
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.
what a great reflection!
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...
That is very special and I learned something today. Tha k you. Happy NewYear
That would be so interesting to see in person!!
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?")
Must go see! Wonderful picture and thank you for the information.
I saw one of those at an Atlanta science museum last fall. I was fascinated, too.
Happy 2013!
