Slate published an article yesterday (which I didn’t see until this morning) in celebration of National Science Fiction Day. It’s tied in with Asimov’s birthday and even includes a classic photograph of Asimov from the 1950s—the one that often appeared in hardback editions of his books and is presumably the most public-domainy of the pictures of Asimov on the Web.

The article, called “Celebrate National Science Fiction Day by Learning To Live in the Future,” argues that we should be using the new technologies available to us to explore the universe more deeply. I certainly agree with the sentiment, but I don’t understand what this “Facebook” thing is the article mentions.
