Another glorious feature of many modern science museums is a movie theater showing IMAX or OMNIMAX films. In some cases the screen is ten stories tall and wraps around you. The Smithsonian's National Air & Space Museu, the popular museum on Earth, has premiered in its Langley Theater some of the best of these films. 'To Fly' brings a catch to my throat even after five or six viewings. I've seen religious leaders of many denominations witness 'Blue Planet' and be converted on the spot to the need to protect the Earth's environment
