This was a star that had left behind the fiery extravagances of its youth, had raced through the violets and blues and greens of the spectrum in a few fleeting billions of years, and now had settled down to a peaceful maturity of unimaginable length. All that had gone before was not a thousandth of what was yet to come; the story of this star had barely begun.

― Arthur C. Clarke, 2001: A Space Odyssey

I wish I’d read Clarke’s book before rewatching Stanley Kubrick’s film adaptation (in 70mm at the Music Box in Chicago). It would have filled in a lot of context for the famously opaque film. For understanding how the film got made I highly recommend Michael Benson’s Space Odyssey: Stanley Kubrick, Arthur C. Clarke, and the Making of a Masterpiece.
