If I think about it long enough, I'm sure I could reconstruct a long ago heard explanation of exactly how the earth, moon and sun must be positioned to create the various phases of the moon. I suspect we saw it played out in the darkness of our high school's planetarium, or maybe acted it out using twirling students and a flashlight "sun" back in elementary school.
I like that there's a why and a how and that it's all wonderfully logical, but when I looked up tonight, all I saw was a heavenly smile - a reminder that we are loved.
If you've never read Walt Whitman's poem "When I Heard the Learn'd Astronomer" I recommend it. It is short, reader friendly and a wonderful reminder that no matter how much we study and learn about the workings of the universe, the experiencing of it is where the magic lies.
