When I was wee, I often visited the Mid America Science Museum, which introduced me to theremins and tectonics. I was especially fascinated by the movie Powers of Ten, which played on a continuous loop in a dark alcove of a theatre. In its own seventies-tastic way that movie helped me get a sense of the universe’s scale.

I’d never seen anything like it until recently.

This movie is both awesome and awe-inspiring. Every time I watch it raptly I remember what it was to be six again and only starting to discover how wondrous our universe is.
