Weekly Photo Challenge 2: this sign says….

the earth rotates!

Foucault’s pendulum, named after the French physicist Léon Foucault, is a simple device conceived as an experiment to demonstrate the rotation of the Earth. While it had long been known that the Earth rotated, the introduction of the Foucault pendulum in 1851 was the first simple proof of the rotation in an easy-to-see experiment.

The first public exhibition of a Foucault pendulum took place in February 1851 in the Meridian of the Paris Observatory. A few weeks later Foucault made his most famous pendulum when he suspended a 28 kg brass-coated lead bob with a 67 meter long wire from the dome of the Panthéon, Paris. The plane of the pendulum’s swing rotated clockwise 11° per hour, making a full circle in 32.7 hours.(Wikipedia)

We saw this when we visited the Pantheon a few years back. What a sign! I stood and watched and took photos as I watched the pendulum inch itself along the degree marks. Foucault’s pendulum had tucked itself away in my knowledge bank for a long time, a miracle I wanted to see. And seeing it felt like I’d completed some circuit of my own.

Yo Yo Ma and Wiki

Wiki Blackout

Today Wikipedia is dark. An extraordinary decision by Wikipedia founder Jimmy Wales to protest two bills now before Congress.  “The protest is aimed at the Stop Online Piracy Act in the House and the Protect  Intellectual Property Act under consideration in the Senate,” reported Fox News. Both bills would, in essence, censor the freedom of the Internet.

I believe in protest and applaud Wales’ decision to shut down one of the Internet’s most visited sites, but I can imagine college students, just back in class, having just received a research assignment, going to Wiki this morning and finding it dark. What a shock! Information is not necessarily at a fingertip distance. The shutdown is only for 24 hours so I don’t expect them to go scurrying to the library necessarily, but perhaps it will cause thought.

I’m reminded of something Yo Yo Ma said. A couple of weeks ago, we watched the Lincoln Center Honors and as one of the honorees, he sat in a box with the President and First Lady and watched as a film clip reviewed his life and work. And at one point, his voice, in voice-over, said, “Every day I make an effort to go toward what I don’t understand.”

I hastily scribbled down the line so I wouldn’t forget the exact words and I put the scrap of paper next to my writing area.

Every day I make an effort to go toward what I don’t understand.

Years ago, I wouldn’t let students use Wiki as a source, but over time the site has proved its reliability and is one I use–we all use-to find something quick. And sometimes not only quick but in depth. And sources for more information. It’s one of the places I go toward when I don’t understand.

Every day I make an effort to go toward what I don’t understand.

That’s what writing does. It aims for what the writer doesn’t understand. I’m grateful for that direction. I’ve studied everything from Kansas history to mythology on the Internet, looking for information, wanting to understand my subject. Writers research. We look.

But even if you’re not a writer, if your talent lies in reading, you are still going toward what you don’t understand. Just walking into each day, when you think about it, is going toward what’s not understood. We don’t know what’s going to happen, even if we think we do.

What I don’t understand fills volumes.

So I’ll miss Wiki today if I have to suddenly find out something but I applaud the protest and the time it’s given me to think about where I need to head today. Which piece of what I don’t understand will be the focal point of wondering?
