Libration

 ,

This is just good.  A clear explanation of libration, set to music.  And how often do you have a piece of formal music vetted by NASA scientists?

As it says on the credits, music by Matthew Schickele; sung by Hai-Ting Chinn; with piano by Erika Switzer.


And . . . 

I've got some nifty stuff coming up soon.  Keep watching the Web!
