In response to The Daily Post’s weekly photo challenge: “Shadowed.”
I think I missed on this one. I forgot it was suppose to be “not the obvious shot.” I was just excited to see a shadow I would have not thought of taking before. I might have gone back to taking a picture of my dogs. [laughing]
From the Institutes sign:
Why is it Important: In 1851, Jean-Bernard-Leon Foucault proved that the Earth turns using a pendulum like this one.
What would you see if you stood here all day? At 9:30 am the museum starts the pendulum swinging in a North-South direction. During the day the pendulum knocks down a peg every 20-25 minutes, making it to change direction. By 5pm half of the pegs have fallen.
What’s going on? The fact that the Earth is spinning and the pendulum is swinging creates this interesting effect.
