Foucault Pendulum

It's not a very good photo of the Foucault pendulum at work, but it's the only one I took where one can actually see the pendulum. It's hanging in a wire eight floors up and swings to push down little wooden pegs. I stood in the stairs on the fifth floor taking the photo.

It was another productive day at work although I encountered a problem with a program that I have never seen before, it will be interesting to figure it out.

The weather was dreary again, wet and cold, but no snow.
