'Star Wars,' 'Doctor Who,' 'Forgotten Realms,' even 'Firefly' and 'The X-Files' have shared world novels and other media. I can't help but notice these settings have large shelf space in bookstores, so their publishers and authors are getting something right.

I'd say Harvard graduates leave here with a sense of the possible and the limit - and a sense that there are no limits to what humans can do and that you can always be pushing, whatever limit you think might be there.
